1 00:00:04,120 --> 00:00:07,160 Speaker 1: Get in touch with technology with tech Stuff from how 2 00:00:07,200 --> 00:00:13,800 Speaker 1: stuff works dot com. Hey there, and welcome to tech Stuff. 3 00:00:13,840 --> 00:00:16,320 Speaker 1: I'm your host, Jonathan Strickland. I'm an executive producer and 4 00:00:16,360 --> 00:00:19,840 Speaker 1: I love all things tech. And this is our fourth 5 00:00:19,840 --> 00:00:23,280 Speaker 1: episode about DARPA, And after this episode I will switch 6 00:00:23,360 --> 00:00:26,560 Speaker 1: to some other topics for a while. But DARPA's history 7 00:00:26,600 --> 00:00:29,880 Speaker 1: is incredibly complicated and it's intertwined with some of the 8 00:00:29,920 --> 00:00:34,320 Speaker 1: most important technologies we interact with today, So we will 9 00:00:34,479 --> 00:00:37,440 Speaker 1: revisit this topic in the future. Will come back and 10 00:00:37,479 --> 00:00:40,520 Speaker 1: continue the story of DARPA. But I did not want 11 00:00:40,560 --> 00:00:44,599 Speaker 1: to turn tech stuff into DARPA stuff, So after this one, 12 00:00:44,600 --> 00:00:47,000 Speaker 1: I figure we'll move on to something else and maybe 13 00:00:47,080 --> 00:00:49,120 Speaker 1: in a few weeks we'll pick up where we left 14 00:00:49,159 --> 00:00:52,639 Speaker 1: off today. In our last episode, we covered a lot 15 00:00:52,720 --> 00:00:55,360 Speaker 1: more of the technology that was developed as part of 16 00:00:55,440 --> 00:00:58,480 Speaker 1: the efforts in the Vietnam War, and I guess now 17 00:00:58,480 --> 00:01:00,920 Speaker 1: it's a good time to remind every in the DARPA, 18 00:01:01,040 --> 00:01:03,600 Speaker 1: which back in the sixties was known by its original 19 00:01:03,680 --> 00:01:07,759 Speaker 1: name ARPA, was not an R and D facility itself, 20 00:01:07,840 --> 00:01:10,800 Speaker 1: not truly. It was more of an agency that would 21 00:01:10,800 --> 00:01:15,720 Speaker 1: award contracts to other organizations such as think tanks, universities, 22 00:01:15,840 --> 00:01:20,639 Speaker 1: defense contractors, and stuff like that. ARPA slash DARPA would 23 00:01:20,760 --> 00:01:24,520 Speaker 1: fund the work and they would also set the expectations, 24 00:01:24,600 --> 00:01:26,840 Speaker 1: the guidelines, you know what it was that they were 25 00:01:26,840 --> 00:01:29,279 Speaker 1: hoping to get out of it. But the actual science 26 00:01:29,280 --> 00:01:31,640 Speaker 1: and development was going on throughout the United States and 27 00:01:31,680 --> 00:01:35,080 Speaker 1: all these different facilities, and these projects were frequently top 28 00:01:35,120 --> 00:01:38,000 Speaker 1: top top secret, meaning the people who worked on them 29 00:01:38,000 --> 00:01:41,040 Speaker 1: would keep it quiet even from their co workers. So 30 00:01:41,120 --> 00:01:44,040 Speaker 1: only people at the top of DARPA really tended to 31 00:01:44,080 --> 00:01:47,240 Speaker 1: know all about the bits and pieces, and sometimes even 32 00:01:47,280 --> 00:01:50,480 Speaker 1: the director wasn't fully aware of everything that was going on. 33 00:01:50,560 --> 00:01:54,000 Speaker 1: That's how classified some of these projects were. In nineteen 34 00:01:54,080 --> 00:01:58,480 Speaker 1: sixty nine, while several ARPA research projects were all tied 35 00:01:58,560 --> 00:02:01,920 Speaker 1: up in the Vietnam War, a group of computer networking 36 00:02:01,960 --> 00:02:07,800 Speaker 1: specialists would initiate the original Arpanet Connections. ARPANETT was the 37 00:02:07,880 --> 00:02:10,480 Speaker 1: R and D project to create a means for different 38 00:02:10,480 --> 00:02:14,000 Speaker 1: computers to send data back and forth between each other, 39 00:02:14,480 --> 00:02:18,320 Speaker 1: even if those computers relied upon different computer languages, and 40 00:02:18,360 --> 00:02:21,960 Speaker 1: even if they were separated by many many miles from 41 00:02:22,120 --> 00:02:25,480 Speaker 1: one another. Part of this required the design and production 42 00:02:25,639 --> 00:02:29,919 Speaker 1: of a brand new technology a router. ARPA had contracted 43 00:02:29,960 --> 00:02:34,040 Speaker 1: the company BBN Technologies to build the first routers back 44 00:02:34,080 --> 00:02:36,880 Speaker 1: in nineteen sixty eight, and then it took a year. 45 00:02:37,040 --> 00:02:41,160 Speaker 1: But on October twenty, nineteen sixty nine, computers at the 46 00:02:41,320 --> 00:02:45,400 Speaker 1: Stanford Research Institute, at the University of California and Santa 47 00:02:45,440 --> 00:02:49,239 Speaker 1: Barbara and at the University of Utah would connect through 48 00:02:49,320 --> 00:02:53,720 Speaker 1: these routers. The first message sent across this three node 49 00:02:53,919 --> 00:03:00,400 Speaker 1: network was low l O. This was actually Christopher Lines 50 00:03:00,560 --> 00:03:04,359 Speaker 1: attempt to log in l O g I N to 51 00:03:04,520 --> 00:03:08,160 Speaker 1: the s r I computer remotely, but the s r 52 00:03:08,200 --> 00:03:11,600 Speaker 1: I computer crashed in mid message, and so low is 53 00:03:11,639 --> 00:03:15,359 Speaker 1: all we got. Also, how typical is it that the 54 00:03:15,480 --> 00:03:18,040 Speaker 1: server goes down just when you have something important to 55 00:03:18,080 --> 00:03:20,480 Speaker 1: send to it? It dates all the way back to 56 00:03:20,560 --> 00:03:24,480 Speaker 1: the beginning of the ARPA net. But more seriously, this 57 00:03:24,520 --> 00:03:27,480 Speaker 1: connection showed that remote computers would be able to send 58 00:03:27,560 --> 00:03:32,000 Speaker 1: data back and forth using network communication standards and also 59 00:03:32,240 --> 00:03:37,280 Speaker 1: relying upon technologies like packet switching that involves dividing data 60 00:03:37,440 --> 00:03:41,480 Speaker 1: such as the data that represents a file, into smaller packets, 61 00:03:41,680 --> 00:03:44,680 Speaker 1: and each packet has information about where the data is from, 62 00:03:44,800 --> 00:03:47,400 Speaker 1: where it's going, and how it fits into the overall 63 00:03:47,480 --> 00:03:51,080 Speaker 1: collection of information so that you can um when I 64 00:03:51,120 --> 00:03:54,520 Speaker 1: say you, so that a computer can reconstruct the file. 65 00:03:55,000 --> 00:03:57,760 Speaker 1: These ideas we get fleshed out over the next several years. 66 00:03:58,200 --> 00:04:00,800 Speaker 1: An important moment would happen to night teen seventy four 67 00:04:00,840 --> 00:04:04,280 Speaker 1: when vent Surf and Bob con would publish a protocol 68 00:04:04,480 --> 00:04:08,880 Speaker 1: for Packet Network Interconnection, which laid out the principles behind TCP. 69 00:04:09,400 --> 00:04:11,880 Speaker 1: But I've done full episodes about ur PONET, so for 70 00:04:11,960 --> 00:04:15,760 Speaker 1: this episode, we'll just remind you that that was something 71 00:04:15,800 --> 00:04:18,520 Speaker 1: that was happening at this time, and will also point 72 00:04:18,520 --> 00:04:20,640 Speaker 1: out some of the big moments as they tie back 73 00:04:20,680 --> 00:04:23,159 Speaker 1: into our PA. So the main purpose of our Bonette, 74 00:04:23,160 --> 00:04:26,000 Speaker 1: by the way, that was just to create those methodologies 75 00:04:26,040 --> 00:04:30,200 Speaker 1: for computer networks. But one of the applications, perhaps one 76 00:04:30,200 --> 00:04:34,240 Speaker 1: of the benefits that ar Bo was really interested in, 77 00:04:34,440 --> 00:04:38,279 Speaker 1: was the idea that by creating distributed networks of computers, 78 00:04:38,760 --> 00:04:42,320 Speaker 1: the US could maintain some communications and command structures in 79 00:04:42,360 --> 00:04:45,680 Speaker 1: the event of a nuclear strike. So it's kind of scary, 80 00:04:45,720 --> 00:04:48,640 Speaker 1: but it's also really interesting when you think of it 81 00:04:48,760 --> 00:04:53,599 Speaker 1: from a communication standpoint. If you have a concentrated computer center, 82 00:04:54,080 --> 00:04:58,360 Speaker 1: let's say that you've got a known defense computer at 83 00:04:58,400 --> 00:05:03,120 Speaker 1: a university, Well, that is a potential target. If your 84 00:05:03,200 --> 00:05:07,039 Speaker 1: adversary knows that there's a computer at that location and 85 00:05:07,040 --> 00:05:10,960 Speaker 1: they know that it's of critical importance, they may target it. 86 00:05:11,440 --> 00:05:13,520 Speaker 1: And if they take it down, then you lose it, 87 00:05:13,800 --> 00:05:17,760 Speaker 1: and that is another problem for you to have to handle. 88 00:05:17,839 --> 00:05:20,839 Speaker 1: But if you create a means for computers to work 89 00:05:20,880 --> 00:05:23,680 Speaker 1: together across a big network and it spreads all over 90 00:05:23,720 --> 00:05:28,799 Speaker 1: the country, you have distributed your computing power significantly. And 91 00:05:29,360 --> 00:05:31,640 Speaker 1: even if a strike were to take down part of 92 00:05:31,680 --> 00:05:35,000 Speaker 1: that network, because the nature of the network itself, the 93 00:05:35,040 --> 00:05:39,440 Speaker 1: rest of it may continue to operate without the section 94 00:05:39,480 --> 00:05:41,880 Speaker 1: that has been taken out, which means you still have 95 00:05:41,960 --> 00:05:46,240 Speaker 1: some of your communications and control systems in place. So 96 00:05:46,279 --> 00:05:49,920 Speaker 1: it was looked at as a defense measure as well, 97 00:05:50,040 --> 00:05:53,080 Speaker 1: not just a means of having computers be able to 98 00:05:53,120 --> 00:05:56,160 Speaker 1: communicate with one another, but it was an added benefit. 99 00:05:56,520 --> 00:05:59,240 Speaker 1: Also in nineteen sixty nine, are PA and the U. 100 00:05:59,360 --> 00:06:03,040 Speaker 1: S Army with Bell Labs and the Williams Research Corporation 101 00:06:03,080 --> 00:06:07,560 Speaker 1: to develop the w R nineteen turbo fan engine. This 102 00:06:07,640 --> 00:06:12,160 Speaker 1: engine acts as the power plant for many different cruise missiles. 103 00:06:12,200 --> 00:06:14,599 Speaker 1: And I actually had to look this up because I 104 00:06:14,640 --> 00:06:18,080 Speaker 1: was not familiar with the term power plant when it 105 00:06:18,160 --> 00:06:22,479 Speaker 1: comes to things like missiles and jets and airplanes. I 106 00:06:22,480 --> 00:06:25,120 Speaker 1: think a power plant as a place that is used 107 00:06:25,160 --> 00:06:28,320 Speaker 1: to generate electricity. But power plant in this context is 108 00:06:28,320 --> 00:06:30,920 Speaker 1: an apparatus that provides power for device. It's not a 109 00:06:30,960 --> 00:06:34,200 Speaker 1: big surprise. And so the power in this particular scenario 110 00:06:34,760 --> 00:06:37,359 Speaker 1: is the power to fly through the air. So not 111 00:06:37,640 --> 00:06:40,760 Speaker 1: that mysterious and just threw me for a loop the 112 00:06:40,800 --> 00:06:43,160 Speaker 1: first time I saw it, because despite the fact that 113 00:06:43,200 --> 00:06:45,800 Speaker 1: I've been doing this for ten years, that I'm forty 114 00:06:45,839 --> 00:06:48,640 Speaker 1: three years old, I don't think I've ever actually encountered 115 00:06:48,680 --> 00:06:54,120 Speaker 1: that phrasing before. Meanwhile, while this turbo fan is in development, 116 00:06:54,120 --> 00:06:57,279 Speaker 1: while ar Panetta is coming online, ARPO was also funding 117 00:06:57,279 --> 00:07:01,760 Speaker 1: advancements in underwater propulsion systems. So not just this turbo 118 00:07:01,839 --> 00:07:04,039 Speaker 1: fan for going through the air, they were also looking 119 00:07:04,040 --> 00:07:07,160 Speaker 1: at underwater systems. The U. S. Navy had already funded 120 00:07:07,160 --> 00:07:10,320 Speaker 1: work out of the Applied Research Laboratory at Penn State 121 00:07:10,840 --> 00:07:13,760 Speaker 1: for a system that was called the Stored Chemical Energy 122 00:07:13,840 --> 00:07:18,200 Speaker 1: Propulsion System or SKEPS s c e p S. This 123 00:07:18,280 --> 00:07:22,240 Speaker 1: was used to power torpedoes. ARPA would fund subsequent research 124 00:07:22,560 --> 00:07:26,240 Speaker 1: to increase the operation duration for those systems to have 125 00:07:26,400 --> 00:07:30,360 Speaker 1: them be long endurance systems in other words, and these 126 00:07:30,560 --> 00:07:35,160 Speaker 1: were systems that were relying upon thermal chemical reactions, so 127 00:07:35,680 --> 00:07:39,880 Speaker 1: you would have them burned through what was essentially fuel. 128 00:07:40,160 --> 00:07:41,800 Speaker 1: So they had to come up with new ways to 129 00:07:41,880 --> 00:07:45,080 Speaker 1: replenish that. The result of this was an improvement over 130 00:07:45,080 --> 00:07:47,520 Speaker 1: the old technology, and it would be incorporated in the 131 00:07:47,560 --> 00:07:53,120 Speaker 1: design of the m K fifty torpedo. In anti war 132 00:07:53,280 --> 00:07:56,680 Speaker 1: sentiment was on the rise in the United States. The 133 00:07:56,800 --> 00:08:00,760 Speaker 1: Vietnam War conflict had been dragging on for were quite 134 00:08:00,760 --> 00:08:05,440 Speaker 1: some time, and the news was just devastating out of Vietnam. 135 00:08:05,520 --> 00:08:08,040 Speaker 1: For one thing, via the Vietnam War was one of 136 00:08:08,040 --> 00:08:12,960 Speaker 1: the first real conflicts where reporters on the ground were 137 00:08:13,000 --> 00:08:17,800 Speaker 1: able to send back footage and real stories of what 138 00:08:17,840 --> 00:08:20,800 Speaker 1: was going on, and it was not These were not 139 00:08:20,880 --> 00:08:24,960 Speaker 1: positive stories. One place where this anti war sentiment really 140 00:08:25,000 --> 00:08:28,720 Speaker 1: became apparent was at the University of Illinois at Urbana Champagne. 141 00:08:29,040 --> 00:08:33,040 Speaker 1: There an enormous computer, the fastest in the world at 142 00:08:33,080 --> 00:08:37,120 Speaker 1: that time, was the bull's eye of this target. The 143 00:08:37,200 --> 00:08:41,760 Speaker 1: computer was called the ILIAC four I L L I 144 00:08:42,000 --> 00:08:47,439 Speaker 1: A C four. Professor Daniel L. Slotnick who had called 145 00:08:47,559 --> 00:08:50,199 Speaker 1: John von Neumann, a mentor he had studied under. Von 146 00:08:50,280 --> 00:08:54,400 Speaker 1: Neuman was the Arbors scientist in charge of the Iliac 147 00:08:54,520 --> 00:08:57,040 Speaker 1: four project, and his goal was to get the ILIAC 148 00:08:57,120 --> 00:09:00,319 Speaker 1: four up to being able to process a billion instructs 149 00:09:00,320 --> 00:09:05,040 Speaker 1: per second. It was running calculations related to ballistic missiles 150 00:09:05,160 --> 00:09:07,960 Speaker 1: as well as the possibility of using weather modification for 151 00:09:08,120 --> 00:09:11,400 Speaker 1: defense top secret stuff in other words, because it was 152 00:09:11,440 --> 00:09:15,040 Speaker 1: a Department of Defense computer running at this university. And 153 00:09:15,080 --> 00:09:19,080 Speaker 1: in early nineteen seventy a student reporter was able to 154 00:09:19,120 --> 00:09:22,880 Speaker 1: attend a meeting where they talked about how this computer's 155 00:09:22,920 --> 00:09:26,080 Speaker 1: time was being allocated, and in that story that the 156 00:09:26,160 --> 00:09:29,720 Speaker 1: student reporter published, the reporter revealed that one of the 157 00:09:29,800 --> 00:09:32,079 Speaker 1: things the computer was being used to do was related 158 00:09:32,120 --> 00:09:36,720 Speaker 1: to nuclear weapons. Slot Nick was caught between anti war 159 00:09:36,840 --> 00:09:41,160 Speaker 1: protesters and the Department of Defense. He managed to anger 160 00:09:41,280 --> 00:09:44,760 Speaker 1: both sides at the same time when he said he 161 00:09:45,480 --> 00:09:48,520 Speaker 1: took on this project in order to be able to 162 00:09:48,559 --> 00:09:51,640 Speaker 1: build the computer. He wanted to have this computer capable 163 00:09:51,679 --> 00:09:54,760 Speaker 1: of running a billion operations per second, and in order 164 00:09:54,760 --> 00:09:57,040 Speaker 1: to do that he was going to need millions of dollars, 165 00:09:57,080 --> 00:10:00,560 Speaker 1: and the Department of Defense offered that operat tunity. He 166 00:10:00,600 --> 00:10:03,320 Speaker 1: said that if the Red Cross had done the same, 167 00:10:03,360 --> 00:10:05,160 Speaker 1: he would have taken the money from the Red Cross 168 00:10:05,200 --> 00:10:07,240 Speaker 1: and had nothing to do with the Department of Defense. 169 00:10:07,800 --> 00:10:10,959 Speaker 1: This had the benefit of taking off both the anti 170 00:10:11,040 --> 00:10:15,800 Speaker 1: war protesters and the Department of Defense. Nobody was happy 171 00:10:15,840 --> 00:10:19,480 Speaker 1: about this. Tensions continued to grow, and there were more 172 00:10:19,520 --> 00:10:23,680 Speaker 1: than a few violent incidents on and around the University 173 00:10:23,679 --> 00:10:26,720 Speaker 1: of Illinois campus in the months following this news report. 174 00:10:27,280 --> 00:10:30,360 Speaker 1: So in June of that year, the university reported to 175 00:10:30,480 --> 00:10:33,400 Speaker 1: ARPA that the university was no longer going to be 176 00:10:33,400 --> 00:10:36,320 Speaker 1: able to keep this computer safe. The ILIAC four was 177 00:10:36,480 --> 00:10:40,160 Speaker 1: in danger if it stayed on campus, and so ARPA 178 00:10:40,280 --> 00:10:44,000 Speaker 1: chose to move the computer, which by the way, was huge. 179 00:10:44,120 --> 00:10:47,040 Speaker 1: I mean it was several feet long, several feet wide, 180 00:10:47,160 --> 00:10:51,280 Speaker 1: weight an enormous amounts, So moving it was not a 181 00:10:51,280 --> 00:10:53,680 Speaker 1: an easy option. In fact, just to plug in the 182 00:10:53,679 --> 00:10:56,360 Speaker 1: power supply you would have to have a forklift. So 183 00:10:57,240 --> 00:10:58,720 Speaker 1: this was not an easy thing to move. But they 184 00:10:58,760 --> 00:11:00,960 Speaker 1: did relocate it. They moved did all the way out 185 00:11:01,040 --> 00:11:04,440 Speaker 1: to California to NASA's Institute for Advanced Computation at the 186 00:11:04,440 --> 00:11:08,240 Speaker 1: AIMS Research Center. Now, following this, while you have this 187 00:11:08,320 --> 00:11:12,720 Speaker 1: anti war sentiment growing, you have these these violent protests happening. 188 00:11:13,520 --> 00:11:17,520 Speaker 1: Senator Mike Mansfield would introduce a bill that would limit 189 00:11:17,679 --> 00:11:21,920 Speaker 1: ARPA's projects to those that had a quote specific military 190 00:11:21,920 --> 00:11:26,079 Speaker 1: function end quote. ARPA would end up having trouble getting 191 00:11:26,160 --> 00:11:31,400 Speaker 1: budget for speculative or bleeding edge research. They were mostly 192 00:11:31,679 --> 00:11:36,760 Speaker 1: trying to look into ways of pushing the bleeding edge 193 00:11:36,760 --> 00:11:40,000 Speaker 1: of technology out much further than anyone else. In fact, 194 00:11:40,000 --> 00:11:42,680 Speaker 1: the whole goal of ARPA or DARPA as it would 195 00:11:42,760 --> 00:11:45,240 Speaker 1: later be known, was to make certain that the United 196 00:11:45,240 --> 00:11:48,520 Speaker 1: States would never be left behind again, that another spot 197 00:11:48,640 --> 00:11:52,400 Speaker 1: Nick type event would never happen to the US, that 198 00:11:52,480 --> 00:11:55,800 Speaker 1: the US would always be on the forefront of that technology, 199 00:11:56,040 --> 00:11:59,080 Speaker 1: which would mean having to do a lot of exploratory 200 00:11:59,200 --> 00:12:04,960 Speaker 1: research and development that you could not easily tie into 201 00:12:05,080 --> 00:12:11,840 Speaker 1: active military efforts because you're looking ahead to anticipate problems 202 00:12:11,880 --> 00:12:14,079 Speaker 1: that you don't have yet but you think are around 203 00:12:14,120 --> 00:12:19,079 Speaker 1: the corner. So this was a real blow to the agency. 204 00:12:19,240 --> 00:12:22,800 Speaker 1: In addition, the Secretary of Defense would order ARPA to 205 00:12:22,840 --> 00:12:25,800 Speaker 1: be removed from the Pentagon, so the agency's new office 206 00:12:25,800 --> 00:12:30,040 Speaker 1: would be almost three miles away in Arlington, Virginia, and 207 00:12:30,120 --> 00:12:32,280 Speaker 1: that would mean that you would no longer have that 208 00:12:32,480 --> 00:12:37,760 Speaker 1: very quick, immediate access to Pentagon officials. You weren't working 209 00:12:37,840 --> 00:12:40,679 Speaker 1: side by side with them anymore. No one at ARPA, 210 00:12:40,800 --> 00:12:43,320 Speaker 1: not even the director, was really sure if the agency 211 00:12:43,440 --> 00:12:45,600 Speaker 1: was going to be around much longer or not. There 212 00:12:45,679 --> 00:12:48,880 Speaker 1: was a serious worry that the agency might just fizzle 213 00:12:48,920 --> 00:12:54,360 Speaker 1: out without a formal conclusion. But the agency wasn't officially 214 00:12:54,400 --> 00:12:57,120 Speaker 1: shut down, and so it would continue to fund R 215 00:12:57,160 --> 00:13:00,440 Speaker 1: and D work in various projects. I'll explain a little 216 00:13:00,480 --> 00:13:02,839 Speaker 1: bit more in just a second, but first let's take 217 00:13:02,880 --> 00:13:13,160 Speaker 1: a quick break to thank our sponsor. ARFA was also 218 00:13:13,360 --> 00:13:16,560 Speaker 1: funding work to develop low weight mirrors made out of 219 00:13:16,600 --> 00:13:20,440 Speaker 1: beryllium for use, and stuff like infrared telescopes and ballistic 220 00:13:20,480 --> 00:13:25,040 Speaker 1: missile defense systems and weapons guidance systems ended up being 221 00:13:25,080 --> 00:13:28,199 Speaker 1: useful for lots of stuff, especially in space. I mean anytime, 222 00:13:28,679 --> 00:13:31,200 Speaker 1: and I'll mention this again towards the end of this episode, 223 00:13:31,200 --> 00:13:34,560 Speaker 1: anytime you can reduce the amount of weight of the 224 00:13:34,559 --> 00:13:37,360 Speaker 1: components you're sending up into space, you want to do 225 00:13:37,440 --> 00:13:45,280 Speaker 1: it because weight essentially equates money. The heavier your payload 226 00:13:45,360 --> 00:13:47,120 Speaker 1: is to get into space, the more expensive it's going 227 00:13:47,160 --> 00:13:49,600 Speaker 1: to be to get up there. So this was an 228 00:13:49,640 --> 00:13:53,480 Speaker 1: important development not just for these military guidance systems and 229 00:13:53,600 --> 00:13:59,520 Speaker 1: defense systems, but for space faring stuff overall. Are but 230 00:13:59,720 --> 00:14:03,160 Speaker 1: also funded development of technologies that would be incorporated into 231 00:14:03,200 --> 00:14:05,800 Speaker 1: a new generation of detection equipment that could pick up 232 00:14:05,840 --> 00:14:10,360 Speaker 1: Soviet submarine movements. Uh. The project was considered one of 233 00:14:10,360 --> 00:14:14,560 Speaker 1: the agency's biggest successes, with the resulting technology being deployed 234 00:14:14,559 --> 00:14:17,640 Speaker 1: in the early nineteen eighties. So again you see how 235 00:14:17,720 --> 00:14:22,520 Speaker 1: far ahead the agency is from the production of technology. 236 00:14:22,600 --> 00:14:25,680 Speaker 1: You know, it's several years out from where they're doing 237 00:14:25,760 --> 00:14:27,880 Speaker 1: the research and development. They do the r and D 238 00:14:27,960 --> 00:14:30,720 Speaker 1: work in the early seventies, it's not really ready to 239 00:14:30,800 --> 00:14:34,680 Speaker 1: be rolled out in an application until the nineteen eighties. 240 00:14:34,920 --> 00:14:38,920 Speaker 1: But that was again are PA's argument. They said, we 241 00:14:38,960 --> 00:14:42,359 Speaker 1: are necessary to be able to work on these problems 242 00:14:42,680 --> 00:14:45,560 Speaker 1: and anticipate these things so that we're ready to go 243 00:14:46,240 --> 00:14:49,160 Speaker 1: within a decade or so. But if we're not doing that, 244 00:14:49,200 --> 00:14:52,960 Speaker 1: if we're being reactionary instead of proactive, we're going to 245 00:14:53,040 --> 00:14:56,440 Speaker 1: be behind the game. John Lehman, who was Secretary of 246 00:14:56,440 --> 00:14:59,760 Speaker 1: the Navy in nineteen would end up saying that because 247 00:15:00,000 --> 00:15:03,760 Speaker 1: of these submarine sensors, if a war were to ever 248 00:15:03,800 --> 00:15:06,160 Speaker 1: break out between the United States and the Soviet Union, 249 00:15:06,480 --> 00:15:10,040 Speaker 1: those sensors would give him the capability to attack all 250 00:15:10,120 --> 00:15:12,640 Speaker 1: Soviet subs that were in deployment within the first five 251 00:15:12,680 --> 00:15:15,720 Speaker 1: minutes of that war. So it was considered to be 252 00:15:15,760 --> 00:15:19,240 Speaker 1: an incredibly successful technology. It's also indicative of a lot 253 00:15:19,280 --> 00:15:23,800 Speaker 1: of DARPA's early work, which focused largely on developing sensor 254 00:15:23,880 --> 00:15:28,240 Speaker 1: technology for all sorts of stuff seismic sensors, acoustic sensors, 255 00:15:28,960 --> 00:15:33,440 Speaker 1: radioactive isotope sensors, etcetera. So there's also no getting around 256 00:15:33,440 --> 00:15:35,600 Speaker 1: the fact that most of the technologies I've talked about 257 00:15:35,640 --> 00:15:39,840 Speaker 1: in these episodes are meant either to defend against or attack, 258 00:15:40,240 --> 00:15:43,400 Speaker 1: or to make attacks more effective. They're all supposed to 259 00:15:44,120 --> 00:15:48,280 Speaker 1: be related to military stuff, after all, But this next 260 00:15:48,320 --> 00:15:51,360 Speaker 1: bit is sort of a relief from that. In the 261 00:15:51,400 --> 00:15:54,320 Speaker 1: early nineteen seventies, are PA funded research into what was 262 00:15:54,360 --> 00:15:58,880 Speaker 1: called glassy carbon. This was a foamy sort of stuff 263 00:15:58,960 --> 00:16:01,840 Speaker 1: made from pure carbon, and the foam had some really 264 00:16:01,880 --> 00:16:05,160 Speaker 1: interesting features. It was strong, it didn't weigh very much, 265 00:16:05,320 --> 00:16:08,320 Speaker 1: it was chemically inert, and while the original idea was 266 00:16:08,320 --> 00:16:12,120 Speaker 1: that the stuff might be really important for numerous electrochemical applications. 267 00:16:12,760 --> 00:16:16,840 Speaker 1: One unexpected benefit was that it became a strong candidate 268 00:16:17,040 --> 00:16:20,880 Speaker 1: for material to use in surgical implants like heart valves, 269 00:16:21,000 --> 00:16:23,920 Speaker 1: and so it was. And so this particular ARPA project 270 00:16:24,040 --> 00:16:26,280 Speaker 1: would fund work on a technology that would go on 271 00:16:26,360 --> 00:16:29,520 Speaker 1: to save countless lives, and I think that's pretty cool. 272 00:16:29,880 --> 00:16:32,080 Speaker 1: It's also a good reminder that while some of this 273 00:16:32,200 --> 00:16:36,920 Speaker 1: technology was initially intended specifically for a military purpose or 274 00:16:37,320 --> 00:16:41,840 Speaker 1: to potentially go into military applications, they often would have 275 00:16:42,200 --> 00:16:47,560 Speaker 1: much wider applications than just military ones. In nineteen two, 276 00:16:47,680 --> 00:16:51,640 Speaker 1: are PAS Materials Research Projects developed rare earth permanent magnets 277 00:16:51,640 --> 00:16:55,040 Speaker 1: capable of operating That means is, you know, maintaining their 278 00:16:55,080 --> 00:16:58,880 Speaker 1: magnetism across a range of temperatures that had been identified 279 00:16:58,920 --> 00:17:02,560 Speaker 1: as being military relevant. And it's a pretty big range. 280 00:17:02,840 --> 00:17:06,120 Speaker 1: So on the low end is minus fifty five degrees 281 00:17:06,160 --> 00:17:10,399 Speaker 1: celsius or minus sixty seven fahrenheit. On the hot end 282 00:17:10,440 --> 00:17:13,000 Speaker 1: of the scale, it's a hundred twenty five degrees celsius, 283 00:17:13,000 --> 00:17:16,520 Speaker 1: which is two hundred fifty seven degrees fahrenheit. Now, typically 284 00:17:16,920 --> 00:17:20,879 Speaker 1: heating a magnet will reduce its strength of its magnetic field, 285 00:17:21,040 --> 00:17:24,399 Speaker 1: and cooling a magnet down will increase a permanent magnets 286 00:17:24,440 --> 00:17:27,840 Speaker 1: magnetic field. So why is that Well, from a very 287 00:17:27,880 --> 00:17:32,520 Speaker 1: basic level, a magnet's molecules are largely aligned with one another. 288 00:17:32,560 --> 00:17:35,119 Speaker 1: They're more or less all pointing in the same direction 289 00:17:35,520 --> 00:17:39,119 Speaker 1: within the material. So you've got all these molecules that 290 00:17:39,160 --> 00:17:42,320 Speaker 1: are lined up in parallel, and their north poles are 291 00:17:42,320 --> 00:17:44,120 Speaker 1: all pointing in one direction, their south poles are all 292 00:17:44,119 --> 00:17:46,919 Speaker 1: pointing in the other direction. Heating a magnet up causes 293 00:17:47,080 --> 00:17:50,679 Speaker 1: molecules to move around. Heating stuff up causes molecular movement, 294 00:17:51,359 --> 00:17:54,040 Speaker 1: and the more the molecules move around, the more that 295 00:17:54,080 --> 00:17:56,920 Speaker 1: alignment is compromised. So if you heat up a magnet 296 00:17:57,359 --> 00:18:01,000 Speaker 1: a bit, it starts to lose its magnetic properties. If 297 00:18:01,000 --> 00:18:03,760 Speaker 1: you heat it up enough to a point that's called 298 00:18:03,800 --> 00:18:07,879 Speaker 1: the Curie point, named after Madam Curry, they will no 299 00:18:07,920 --> 00:18:11,959 Speaker 1: longer be magnetic at all. You will have demagnetized your 300 00:18:11,960 --> 00:18:14,160 Speaker 1: magnet by heating it up to this point. It's where 301 00:18:14,480 --> 00:18:16,640 Speaker 1: the molecules will be out of alignment and they will 302 00:18:16,680 --> 00:18:20,480 Speaker 1: not realign. To do that, though, you'd have to heat 303 00:18:20,520 --> 00:18:23,760 Speaker 1: the material a pretty darn hot. The Cury point is 304 00:18:24,520 --> 00:18:27,920 Speaker 1: typically very very very hot for most materials, so for example, 305 00:18:27,960 --> 00:18:32,440 Speaker 1: iron that curi point is like seven seventy degrees celsius. 306 00:18:32,440 --> 00:18:37,720 Speaker 1: It's one thousand, four hundred seventeen degrees fahrenheit. So this 307 00:18:38,000 --> 00:18:41,400 Speaker 1: would mean that it be very rare that you would 308 00:18:41,400 --> 00:18:43,480 Speaker 1: ever encounter those kind of situations. The only way you 309 00:18:43,480 --> 00:18:45,560 Speaker 1: would do it is if you were doing it on purpose. Typically, 310 00:18:46,320 --> 00:18:48,320 Speaker 1: this work was really to make sure that the magnets 311 00:18:48,320 --> 00:18:51,560 Speaker 1: were going to operate according to expectations under hot and 312 00:18:51,680 --> 00:18:58,399 Speaker 1: cold conditions. Also in nineteen two, ARPA officially became DARPA, 313 00:18:58,560 --> 00:19:02,280 Speaker 1: or the Defense Advanced Research Projects Agency, and it would 314 00:19:02,280 --> 00:19:07,400 Speaker 1: stick with that name until nine. In three it would 315 00:19:07,480 --> 00:19:11,280 Speaker 1: drop the D and become ARPA again for three years, 316 00:19:11,760 --> 00:19:15,760 Speaker 1: and then in nine will become DARPA again. But I 317 00:19:15,760 --> 00:19:18,119 Speaker 1: figure we're gonna have a while before we get to 318 00:19:18,160 --> 00:19:20,520 Speaker 1: the nineties, so we'll talk about that when we get there. 319 00:19:21,160 --> 00:19:25,080 Speaker 1: Another DARPA funded innovation in the early nineteen seventies was 320 00:19:25,160 --> 00:19:29,840 Speaker 1: the development of gallium arsenide as a semiconductor material. So 321 00:19:29,880 --> 00:19:34,000 Speaker 1: before the semiconductor electronics relied on these really large component 322 00:19:34,040 --> 00:19:37,680 Speaker 1: parts like vacuum tubes, which meant your basic computer would 323 00:19:37,720 --> 00:19:41,719 Speaker 1: take up an enormous amount of space. Several researchers developed 324 00:19:41,760 --> 00:19:45,399 Speaker 1: semiconductor technologies all the way through the nineteen forties, but 325 00:19:45,440 --> 00:19:48,359 Speaker 1: it would take a while for the semiconductor transistor to 326 00:19:48,480 --> 00:19:52,560 Speaker 1: become practical. The properties of gallium arsenide allowed it to 327 00:19:52,600 --> 00:19:57,000 Speaker 1: host faster transistors running on more power than you could 328 00:19:57,000 --> 00:20:01,159 Speaker 1: put on a silicon transistor. Technology would find its way 329 00:20:01,160 --> 00:20:04,480 Speaker 1: into all sorts of applications, though the military was mostly 330 00:20:04,480 --> 00:20:07,920 Speaker 1: concerned with its use on GPS kits and precision guided 331 00:20:08,040 --> 00:20:12,719 Speaker 1: munitions and other defensive systems. One last bit about the 332 00:20:12,800 --> 00:20:16,120 Speaker 1: Vietnam War and DARPA, because we're getting to the point 333 00:20:16,160 --> 00:20:20,840 Speaker 1: where America was getting ready to withdraw from Vietnam. The 334 00:20:20,880 --> 00:20:24,879 Speaker 1: war became increasingly unpopular as it stretched on, and for 335 00:20:24,960 --> 00:20:27,439 Speaker 1: one thing, in the US, it was never really a 336 00:20:27,480 --> 00:20:30,360 Speaker 1: formal war. The US had started out trying to supply 337 00:20:30,520 --> 00:20:33,399 Speaker 1: aid in the form of technology and training to the 338 00:20:33,400 --> 00:20:36,520 Speaker 1: South Vietnamese government and military, and this was all in 339 00:20:36,560 --> 00:20:40,400 Speaker 1: an effort to stop the growth of communism without getting 340 00:20:40,560 --> 00:20:44,800 Speaker 1: directly involved. That was the goal, was to make sure 341 00:20:44,920 --> 00:20:49,280 Speaker 1: that the South Vietnamese forces were capable of handling this 342 00:20:50,040 --> 00:20:52,720 Speaker 1: without the US having to get directly involved. But obviously 343 00:20:52,760 --> 00:20:56,520 Speaker 1: that did not pan out. Every year since nineteen fifty 344 00:20:56,600 --> 00:20:58,880 Speaker 1: nine had seen an increase in the number of US 345 00:20:58,920 --> 00:21:02,760 Speaker 1: troops sent to the region. In nineteen seventy one, a 346 00:21:02,840 --> 00:21:07,280 Speaker 1: former Rand Corporation analyst named Daniel Ellsberg would leak a 347 00:21:07,359 --> 00:21:11,400 Speaker 1: collection of documents that collectively were called the Pentagon Papers 348 00:21:11,480 --> 00:21:15,520 Speaker 1: to The New York Times. Those documents contained information about 349 00:21:15,560 --> 00:21:19,400 Speaker 1: the US is secret involvement with Vietnam for more than 350 00:21:19,440 --> 00:21:23,520 Speaker 1: a decade. This was actually a detailed report that mc 351 00:21:23,560 --> 00:21:27,520 Speaker 1: namara had asked the Rand Corporation to put together as 352 00:21:27,560 --> 00:21:29,879 Speaker 1: it was going on, sort of an encyclopedia of the 353 00:21:29,960 --> 00:21:34,800 Speaker 1: Vietnam War. And the problem was that at this point 354 00:21:35,000 --> 00:21:38,879 Speaker 1: this analyst leaked the whole thing to The New York Times, 355 00:21:39,520 --> 00:21:42,320 Speaker 1: and it included details on the various ARPA projects that 356 00:21:42,359 --> 00:21:44,919 Speaker 1: had happened in that time, and the involvement of the 357 00:21:45,000 --> 00:21:49,320 Speaker 1: super elitist group of scientists called the Jason's and the 358 00:21:49,480 --> 00:21:52,879 Speaker 1: growing anti war movement was really gaining momentum in the 359 00:21:53,000 --> 00:21:57,080 Speaker 1: United States, and many people were outraged not just about 360 00:21:57,119 --> 00:22:00,119 Speaker 1: the war, but also about these revelations of how the 361 00:22:00,200 --> 00:22:03,399 Speaker 1: US public had been deceived over the years, how the 362 00:22:03,440 --> 00:22:10,359 Speaker 1: government had been purposefully misleading the US population, that is, 363 00:22:10,680 --> 00:22:13,560 Speaker 1: you know, at least supposed to be represented by this government. 364 00:22:14,320 --> 00:22:18,280 Speaker 1: And so it bred this this distrust in the government, 365 00:22:18,359 --> 00:22:21,720 Speaker 1: saying you have been doing all the secret stuff, telling 366 00:22:21,800 --> 00:22:24,399 Speaker 1: us it's one thing when it's really another. The anti 367 00:22:24,440 --> 00:22:27,440 Speaker 1: war sentiment put a lot of pressure on all parties involved. 368 00:22:27,480 --> 00:22:31,320 Speaker 1: Eventually it led to ARPA's director, who was a Dr. 369 00:22:31,400 --> 00:22:35,439 Speaker 1: Steve J. Lucasik, the seventh director of ARPA at that point, 370 00:22:36,000 --> 00:22:39,400 Speaker 1: to sever the ties with the Jason's ARPA was seen 371 00:22:39,440 --> 00:22:41,679 Speaker 1: as the R and D tip on the point of 372 00:22:41,720 --> 00:22:46,040 Speaker 1: the military industrial complex SPEAR, and since the efforts in 373 00:22:46,119 --> 00:22:49,640 Speaker 1: Vietnam didn't prevent the North Vietnamese forces from taking Saigon, 374 00:22:50,480 --> 00:22:53,000 Speaker 1: many were beginning to question the usefulness of such an 375 00:22:53,000 --> 00:22:55,879 Speaker 1: agency in the first place. The experience of Vietnam had 376 00:22:55,920 --> 00:22:59,960 Speaker 1: an enormous effect on the American psyche. The majority of 377 00:23:00,000 --> 00:23:03,480 Speaker 1: Americans felt the war was unethical and a political mistake, 378 00:23:03,880 --> 00:23:07,000 Speaker 1: and that it led to the deaths of thousands of Americans, 379 00:23:07,000 --> 00:23:10,160 Speaker 1: not to mention millions of others. And it taunt Americans 380 00:23:10,720 --> 00:23:14,040 Speaker 1: that the use of force and superior technology would not 381 00:23:14,320 --> 00:23:19,680 Speaker 1: necessarily win out over philosophies and ideology. It wasn't realistic 382 00:23:19,720 --> 00:23:23,560 Speaker 1: to say because we are technologically superior, We're definitely going 383 00:23:23,640 --> 00:23:26,840 Speaker 1: to win. Now, all of this is to say that 384 00:23:26,920 --> 00:23:29,919 Speaker 1: it would make the post Vietnam War era for DARPA 385 00:23:30,119 --> 00:23:33,520 Speaker 1: really challenging. Apart from the name change, which was again 386 00:23:33,520 --> 00:23:36,399 Speaker 1: to indicate that from this point forward, the agency was 387 00:23:36,440 --> 00:23:39,600 Speaker 1: only going to pursue projects that met a specific military need. 388 00:23:40,280 --> 00:23:43,439 Speaker 1: All projects related to the Vietnam War were to stop. 389 00:23:43,760 --> 00:23:48,359 Speaker 1: Project Agile was called an enormous failure, that all the 390 00:23:48,400 --> 00:23:52,040 Speaker 1: attempts to bring research and technology to stop insurgents had 391 00:23:52,080 --> 00:23:56,639 Speaker 1: been ineffective at best and counter productive at worst. Several 392 00:23:56,680 --> 00:24:00,959 Speaker 1: previous ARPA directors who oversaw Project Agile throughout the years 393 00:24:01,359 --> 00:24:05,560 Speaker 1: would admit that their efforts were misguided and ineffective. DARBA 394 00:24:05,680 --> 00:24:10,400 Speaker 1: established a new office called Tactical Technology. This office carried 395 00:24:10,440 --> 00:24:12,440 Speaker 1: out much of the top secret R and D work 396 00:24:12,440 --> 00:24:16,000 Speaker 1: around sensors, improving the technologies that had been part of 397 00:24:16,040 --> 00:24:19,840 Speaker 1: the failed electric fence project, as well as more successful 398 00:24:19,840 --> 00:24:23,360 Speaker 1: projects like VILA and the submarine sensors. And then there 399 00:24:23,440 --> 00:24:26,560 Speaker 1: was the move to research technologies that can mask aircraft 400 00:24:26,680 --> 00:24:31,040 Speaker 1: from radar systems. New advanced air defense missile systems were 401 00:24:31,040 --> 00:24:35,200 Speaker 1: making it increasingly dangerous to fly missions in combat theaters. 402 00:24:35,760 --> 00:24:38,959 Speaker 1: DARPA would tackle this problem by funding research into ways 403 00:24:39,000 --> 00:24:43,720 Speaker 1: that an aircraft might foil radar systems, either by absorbing 404 00:24:43,840 --> 00:24:47,359 Speaker 1: radar waves so that nothing bounces back, or by reflecting 405 00:24:47,480 --> 00:24:50,640 Speaker 1: radar waves off into other directions so that they don't 406 00:24:50,640 --> 00:24:55,520 Speaker 1: return to their radar stations, or both. These projects would 407 00:24:55,560 --> 00:24:59,960 Speaker 1: evolve into have Blue, the first practical stealth combat aircraft. 408 00:25:00,560 --> 00:25:03,480 Speaker 1: This was a proof of concept vehicle the had's first 409 00:25:03,480 --> 00:25:06,520 Speaker 1: test flight in nineteen seventy seven, and there's an interesting 410 00:25:06,560 --> 00:25:09,640 Speaker 1: behind the scenes story that really shows how secretive all 411 00:25:09,680 --> 00:25:13,919 Speaker 1: this stuff was. So the CIA had previously been working 412 00:25:13,960 --> 00:25:18,399 Speaker 1: with Lockheed to develop stealth technology that would culminate with 413 00:25:18,440 --> 00:25:21,960 Speaker 1: an aircraft called the A twelve Ox cart Plane. I 414 00:25:22,000 --> 00:25:25,199 Speaker 1: talked about it in an episode about stealth aircraft. But 415 00:25:25,280 --> 00:25:29,000 Speaker 1: the A twelve was so top secret that even the 416 00:25:29,040 --> 00:25:32,840 Speaker 1: director of DARPA, who was George Hallmeyer at this time, 417 00:25:33,560 --> 00:25:37,159 Speaker 1: he hadn't even heard about it. So when DARPA began 418 00:25:37,200 --> 00:25:41,239 Speaker 1: to look for possible contractors to work on stealth technology, 419 00:25:41,280 --> 00:25:44,680 Speaker 1: they did not initially consider Lockeed. They weren't They didn't 420 00:25:44,720 --> 00:25:47,560 Speaker 1: know that Lockeed had been working on this stuff. They 421 00:25:48,200 --> 00:25:51,960 Speaker 1: originally only reached out to McDonald Douglas and to Northrop. 422 00:25:52,440 --> 00:25:55,840 Speaker 1: When Lockeed executives found out, they petitioned the CIA to 423 00:25:55,960 --> 00:25:59,040 Speaker 1: let them tell DARPA about the stealth technology that the 424 00:25:59,160 --> 00:26:02,199 Speaker 1: Super Secrets Gunkworks division had been doing in order to 425 00:26:02,880 --> 00:26:06,639 Speaker 1: bid on this contract. The CIA would allow Locked to 426 00:26:06,680 --> 00:26:10,560 Speaker 1: tell hal Meyer about the twelve, which later would evolve 427 00:26:10,560 --> 00:26:13,480 Speaker 1: into the SR seventy one reconnaissance aircraft for the Air Force, 428 00:26:13,760 --> 00:26:17,480 Speaker 1: and Lockeed would win this contract. I'll have more to 429 00:26:17,560 --> 00:26:21,000 Speaker 1: say about stealth technology and some of the other tech 430 00:26:21,080 --> 00:26:23,800 Speaker 1: that DARBA worked on towards the end of the seventies 431 00:26:23,840 --> 00:26:25,920 Speaker 1: in just a moment, but first let's take another quick 432 00:26:25,920 --> 00:26:36,680 Speaker 1: break to thank our sponsor. The original design for what 433 00:26:36,760 --> 00:26:40,359 Speaker 1: would become Have Blue would later evolve into the F 434 00:26:40,480 --> 00:26:44,639 Speaker 1: one seventeen stealth fighter. The original design was nicknamed the 435 00:26:44,760 --> 00:26:48,640 Speaker 1: Hopeless Diamond. The sketch was of an aircraft that vaguely 436 00:26:48,680 --> 00:26:52,280 Speaker 1: resembled the Hope Diamond and had lots of facets and 437 00:26:52,359 --> 00:26:56,200 Speaker 1: odd angles. No one was really sure if it would 438 00:26:56,200 --> 00:26:59,840 Speaker 1: be able to fly. The weird angles were part of 439 00:26:59,840 --> 00:27:02,160 Speaker 1: the stealth technology. It was all on effort to redirect 440 00:27:02,200 --> 00:27:05,360 Speaker 1: those incoming radar signals so that they would not return 441 00:27:05,400 --> 00:27:08,240 Speaker 1: to the listing stations. They would bounce off into some 442 00:27:08,280 --> 00:27:10,800 Speaker 1: other directions, kind of like using a mirror to direct 443 00:27:10,800 --> 00:27:13,600 Speaker 1: a ray of light and you just tilt the mirror 444 00:27:13,640 --> 00:27:16,320 Speaker 1: a different direction and the light goes a different way. 445 00:27:16,680 --> 00:27:19,080 Speaker 1: By redirecting the radar signals, it would seem to the 446 00:27:19,200 --> 00:27:22,040 Speaker 1: radar station that there was nothing in that region of 447 00:27:22,080 --> 00:27:24,399 Speaker 1: the sky. That was the whole idea. Much of the 448 00:27:24,400 --> 00:27:26,880 Speaker 1: work on the stealth technology took place on the most 449 00:27:27,000 --> 00:27:30,879 Speaker 1: famous secret base of all time, which of course is 450 00:27:30,960 --> 00:27:34,640 Speaker 1: Area fifty one or the Groom Lake Facility. I've talked 451 00:27:34,640 --> 00:27:37,480 Speaker 1: about this base numerous times in this podcast as well. 452 00:27:37,800 --> 00:27:40,080 Speaker 1: The Air Force would take over the program in the 453 00:27:40,160 --> 00:27:43,720 Speaker 1: late nineteen seventies and conduct flight tests all over the 454 00:27:43,760 --> 00:27:47,240 Speaker 1: Tonopah Test Range, which was seventy miles northwest of Area 455 00:27:47,320 --> 00:27:50,919 Speaker 1: fifty one. Some people would just call that Area fifty two. 456 00:27:51,520 --> 00:27:55,399 Speaker 1: And another big project was in updating the old transit 457 00:27:55,560 --> 00:27:59,639 Speaker 1: navigation system. It was a satellite based navigation system that 458 00:28:00,240 --> 00:28:04,840 Speaker 1: u ARPA had been involved with in the early sixties. 459 00:28:05,359 --> 00:28:08,160 Speaker 1: This effort was to replace that with a more robust 460 00:28:08,320 --> 00:28:12,600 Speaker 1: satellite system. In nineteen seventy three, as America was withdrawing 461 00:28:12,640 --> 00:28:16,360 Speaker 1: from Vietnam, the Pentagon ordered a joint program for a 462 00:28:16,400 --> 00:28:20,040 Speaker 1: single navigation system that all the branches of the military 463 00:28:20,080 --> 00:28:22,720 Speaker 1: would be able to use, because at this point, these 464 00:28:22,800 --> 00:28:25,800 Speaker 1: various military branches had all been working on their own 465 00:28:26,040 --> 00:28:29,600 Speaker 1: systems which were not compatible with one another, and eventually 466 00:28:30,160 --> 00:28:33,480 Speaker 1: um the government said, this doesn't make sense. We should 467 00:28:33,640 --> 00:28:37,560 Speaker 1: have a more unified approach. So this new program was 468 00:28:37,600 --> 00:28:41,360 Speaker 1: called nav Star, and DARPA helped fund the development of 469 00:28:41,360 --> 00:28:45,600 Speaker 1: this program, which by was finally ready for full deployment, 470 00:28:46,120 --> 00:28:50,800 Speaker 1: and it consisted of twenty four satellites with atomic clocks, 471 00:28:50,840 --> 00:28:54,760 Speaker 1: which was necessary for synchronization, and they were launched into 472 00:28:54,840 --> 00:28:59,280 Speaker 1: orbit to give global navigation coverage. This information could be 473 00:28:59,400 --> 00:29:02,800 Speaker 1: used not just to navigate people around the world, but 474 00:29:03,080 --> 00:29:06,920 Speaker 1: also for guided weapons systems. As part of the technology, 475 00:29:06,960 --> 00:29:10,280 Speaker 1: designers included what they called an offset feature. It was 476 00:29:10,360 --> 00:29:14,040 Speaker 1: it was known as selective availability, and it meant that 477 00:29:14,080 --> 00:29:17,080 Speaker 1: if you didn't have the right kind of receiver to 478 00:29:17,400 --> 00:29:20,560 Speaker 1: descramble this information and get a readout, you would actually 479 00:29:20,600 --> 00:29:23,240 Speaker 1: get a result that would be off by several hundred feet, 480 00:29:23,680 --> 00:29:27,760 Speaker 1: which would limit the chances of someone unauthorized making use 481 00:29:27,800 --> 00:29:29,920 Speaker 1: of the system, and it would also keep the GPS 482 00:29:30,000 --> 00:29:34,080 Speaker 1: network impractical for commercial use. That is until President Bill 483 00:29:34,080 --> 00:29:37,480 Speaker 1: Clinton would end the era of selective availability and allow 484 00:29:37,520 --> 00:29:41,200 Speaker 1: civilian systems to access information with essentially the same precision 485 00:29:41,280 --> 00:29:45,880 Speaker 1: as military systems, and at that point GPS receivers were 486 00:29:45,960 --> 00:29:49,520 Speaker 1: accurate enough to be used for things like navigation and cars, 487 00:29:50,200 --> 00:29:53,520 Speaker 1: because before you would be you know, you would have 488 00:29:53,600 --> 00:29:57,520 Speaker 1: like a precision of down two around a few hundred feet. 489 00:29:58,040 --> 00:29:59,920 Speaker 1: That's not very useful when you're trying to look for 490 00:30:00,080 --> 00:30:04,719 Speaker 1: return anyway. During Vietnam, DARPA had funded a few drone 491 00:30:04,760 --> 00:30:08,120 Speaker 1: programs as well. These were very primitive drones compared to 492 00:30:08,160 --> 00:30:09,959 Speaker 1: what we have today, but it was the beginning of 493 00:30:10,000 --> 00:30:15,280 Speaker 1: serious work in unmanned aerial vehicles for reconnaissance and for weaponization. 494 00:30:15,920 --> 00:30:20,560 Speaker 1: They were code named Prairie and Collare. Both were remotely 495 00:30:20,640 --> 00:30:25,160 Speaker 1: piloted vehicles or RPVs, and both used lawnmower motors and 496 00:30:25,200 --> 00:30:27,760 Speaker 1: could carry a payload of about twenty eight pounds or 497 00:30:27,800 --> 00:30:31,600 Speaker 1: twelve point seven kilograms. These would serve as prototypes for 498 00:30:31,720 --> 00:30:34,400 Speaker 1: work in the field, which DARPA would end up handing 499 00:30:34,440 --> 00:30:38,680 Speaker 1: over to the Armed Forces in nineteen seventy seven, DARPA 500 00:30:38,720 --> 00:30:43,200 Speaker 1: would fund another project for an unmanned aerial vehicle called 501 00:30:43,240 --> 00:30:46,560 Speaker 1: Amber that was supposed to be a long endurance u 502 00:30:46,600 --> 00:30:49,000 Speaker 1: a V that would get support from the Navy. As 503 00:30:49,000 --> 00:30:53,479 Speaker 1: the project was proving promising, but in the late nineteen eighties, 504 00:30:53,800 --> 00:30:57,320 Speaker 1: Congress would create a new Joint Program Office to continue 505 00:30:57,360 --> 00:31:00,800 Speaker 1: research and development for unmanned aerial vehicles and DARPA was 506 00:31:00,840 --> 00:31:05,200 Speaker 1: effectively removed from that process. DARPA would move on to 507 00:31:05,320 --> 00:31:09,479 Speaker 1: pursue a new project called Assault Breaker, which had the 508 00:31:09,520 --> 00:31:13,160 Speaker 1: goal of bringing together many different disparate technologies in an 509 00:31:13,200 --> 00:31:16,560 Speaker 1: effort to make them work together in a system of systems. 510 00:31:16,600 --> 00:31:19,440 Speaker 1: This idea of we have all these pieces out there 511 00:31:19,520 --> 00:31:22,320 Speaker 1: and they're all effective, but it would be better if 512 00:31:22,360 --> 00:31:27,239 Speaker 1: we could actually make a cohesive approach to this. So 513 00:31:27,280 --> 00:31:29,200 Speaker 1: the goal was to create a means in which military 514 00:31:29,240 --> 00:31:32,400 Speaker 1: commanders would have an enormous amount of information at their 515 00:31:32,400 --> 00:31:35,920 Speaker 1: disposal and the capability of launching an attack on a target, 516 00:31:35,960 --> 00:31:39,200 Speaker 1: even if that target were well behind enemy lines. This 517 00:31:39,240 --> 00:31:42,760 Speaker 1: would require bringing together all of these different technologies that 518 00:31:42,880 --> 00:31:46,880 Speaker 1: DARPA had played a part in making a reality. Soviet 519 00:31:46,960 --> 00:31:51,320 Speaker 1: Union spies learned about this program, Assault Breaker, and they 520 00:31:51,360 --> 00:31:55,120 Speaker 1: reported back to their superiors in Moscow, and as eventually, 521 00:31:55,200 --> 00:31:58,240 Speaker 1: military personnel in the Soviet Union wrote up a report 522 00:31:58,600 --> 00:32:01,440 Speaker 1: and published it in a journal called Military Thought. It's 523 00:32:01,480 --> 00:32:05,280 Speaker 1: actually a classified journal. Only a few high ranking officials 524 00:32:05,280 --> 00:32:09,040 Speaker 1: really had access to it. Well, high ranking Soviet officials 525 00:32:09,040 --> 00:32:12,160 Speaker 1: and a few U. S. Spies, because, as we know, 526 00:32:12,360 --> 00:32:15,360 Speaker 1: everyone is spying on everyone else all the time, always. 527 00:32:16,040 --> 00:32:19,160 Speaker 1: So when US officials learned that the Soviet government was 528 00:32:19,200 --> 00:32:21,880 Speaker 1: worried that the US was building up a program that 529 00:32:21,920 --> 00:32:26,360 Speaker 1: would give America this incredible advantage in both gathering intelligence 530 00:32:26,400 --> 00:32:29,080 Speaker 1: and acting upon it, spirits started to run high in 531 00:32:29,120 --> 00:32:33,400 Speaker 1: the US because if your enemy is scared, that's good 532 00:32:33,400 --> 00:32:37,640 Speaker 1: news for you. I guess. One cool project that started 533 00:32:37,680 --> 00:32:42,719 Speaker 1: independently from Darba was one that would eventually be called simnet. 534 00:32:43,320 --> 00:32:46,480 Speaker 1: So there was an Air Force pilot named Jack Thorpe 535 00:32:46,920 --> 00:32:50,400 Speaker 1: who was thinking about the possibility of networked flight simulators 536 00:32:50,400 --> 00:32:54,959 Speaker 1: for the purposes of training pilots, you know, combat training 537 00:32:55,200 --> 00:32:57,480 Speaker 1: without actually having to go up in a real jet. 538 00:32:58,000 --> 00:33:00,280 Speaker 1: And he had experienced this on a small scale ld. 539 00:33:00,280 --> 00:33:01,960 Speaker 1: This was not something he just came up with on 540 00:33:02,000 --> 00:33:04,680 Speaker 1: his own. He had already had sort of this experience 541 00:33:05,160 --> 00:33:07,760 Speaker 1: in a system that was at the Flying Training Division 542 00:33:07,840 --> 00:33:11,080 Speaker 1: of Williams Air Force Base, and that system would allow 543 00:33:11,200 --> 00:33:15,600 Speaker 1: two pilots to simulate flying emission together. The simulator was 544 00:33:15,640 --> 00:33:19,120 Speaker 1: complete with hydraulic motion system, so it move you as 545 00:33:19,160 --> 00:33:22,600 Speaker 1: you're piloting the simulated aircraft. But again it was just 546 00:33:22,680 --> 00:33:26,160 Speaker 1: a pair of these simulators that worked together. Thorpe wondered 547 00:33:26,200 --> 00:33:28,320 Speaker 1: if perhaps it would be possible to build out a 548 00:33:28,400 --> 00:33:33,040 Speaker 1: much larger system with multiple UH simulators all connected to 549 00:33:33,080 --> 00:33:36,800 Speaker 1: each other to allow for more complex training. Thorpe wrote 550 00:33:36,840 --> 00:33:40,680 Speaker 1: up a paper titled Future Views Aircrew Training nineteen eighty 551 00:33:40,800 --> 00:33:44,640 Speaker 1: through two thousand. This was in n when he wrote this, 552 00:33:45,040 --> 00:33:49,040 Speaker 1: and he pitched his ideas to top Brass, but they 553 00:33:49,080 --> 00:33:52,560 Speaker 1: didn't take it very seriously. To be fair to them, 554 00:33:53,000 --> 00:33:56,800 Speaker 1: the tech that Thorpe was proposing was incredibly sophisticated for 555 00:33:56,880 --> 00:34:00,040 Speaker 1: the time, and also not many people really knew that 556 00:34:00,240 --> 00:34:02,880 Speaker 1: much about the progress that ARPA net had been making 557 00:34:02,920 --> 00:34:06,360 Speaker 1: in networking different computer systems together, so no one was 558 00:34:06,400 --> 00:34:09,319 Speaker 1: really sure how feasible this was. Thorpe would go on 559 00:34:09,520 --> 00:34:12,799 Speaker 1: doing his career and then he would go to the 560 00:34:12,920 --> 00:34:16,320 Speaker 1: Naval War College to further his education, and after getting 561 00:34:16,320 --> 00:34:19,440 Speaker 1: out of that he was assigned sort of on loan 562 00:34:19,640 --> 00:34:23,120 Speaker 1: by the Air Force to DARPA. While he was at DARPA, 563 00:34:23,360 --> 00:34:26,920 Speaker 1: his boss asked him, hey, gun, any interesting ideas, you know, 564 00:34:27,000 --> 00:34:30,160 Speaker 1: beyond what you're working on. So Thorpe shared his vision 565 00:34:30,239 --> 00:34:33,800 Speaker 1: of these networked simulators, and his boss loved this idea 566 00:34:34,040 --> 00:34:36,920 Speaker 1: and told Thorpe that you should tell this to Larry Lynn, 567 00:34:36,960 --> 00:34:40,479 Speaker 1: who was then the director of DARPA. Larry Lynn liked 568 00:34:40,480 --> 00:34:43,120 Speaker 1: it a lot too, and so yes, Thorpe, how much 569 00:34:43,120 --> 00:34:45,719 Speaker 1: money do you think it would cost to do this project? 570 00:34:46,040 --> 00:34:50,720 Speaker 1: And Thorpe said seventeen million dollars and Lynn said, okay, doky. 571 00:34:50,760 --> 00:34:55,080 Speaker 1: So the program began and it became known as Simulator 572 00:34:55,280 --> 00:35:00,040 Speaker 1: Networking or sim net. DARPA would contract with delt A 573 00:35:00,120 --> 00:35:05,879 Speaker 1: Graphics Incorporated, Perceptronics Incorporated, and bb IN Incorporated to help 574 00:35:05,920 --> 00:35:08,520 Speaker 1: build out the system, and they would subcontract with other 575 00:35:08,560 --> 00:35:11,759 Speaker 1: companies to build all these simulators. And they weren't just 576 00:35:11,840 --> 00:35:15,160 Speaker 1: aircraft simulators. They built tank simulators and other stuff too, 577 00:35:15,480 --> 00:35:18,759 Speaker 1: and they networked them all together. The advantages of these 578 00:35:18,800 --> 00:35:23,440 Speaker 1: simulators over real world training were numerous. Real world combat 579 00:35:23,480 --> 00:35:28,080 Speaker 1: training is obviously very dangerous for some scenarios such as 580 00:35:28,160 --> 00:35:31,200 Speaker 1: let's say you want to operate your aircraft, but you 581 00:35:31,280 --> 00:35:35,279 Speaker 1: also want to jam the sensors on that aircraft. Not 582 00:35:35,320 --> 00:35:38,239 Speaker 1: only is that very dangerous because you're taking away some 583 00:35:38,280 --> 00:35:41,120 Speaker 1: of the information that the pilots are relying upon, it's 584 00:35:41,160 --> 00:35:45,560 Speaker 1: also potentially problematic because depending on where you're flying these 585 00:35:45,600 --> 00:35:50,520 Speaker 1: these training missions, using that jamming technology can affect other 586 00:35:50,800 --> 00:35:57,440 Speaker 1: stuff like commercial flights, or maybe the the airspace of allies, 587 00:35:57,640 --> 00:35:59,960 Speaker 1: or maybe people who aren't your allies. It could be 588 00:36:00,160 --> 00:36:03,080 Speaker 1: really really touchy. But if you simulate it, you can 589 00:36:03,120 --> 00:36:05,760 Speaker 1: do pretty much any scenario that the computer is capable 590 00:36:05,800 --> 00:36:09,840 Speaker 1: of running. So also, because the systems were networked in theory, 591 00:36:09,960 --> 00:36:11,960 Speaker 1: you could have people in different parts of the world 592 00:36:12,160 --> 00:36:14,359 Speaker 1: all training together. You didn't have to get them all 593 00:36:14,400 --> 00:36:17,040 Speaker 1: in the same place at the same time, though, you 594 00:36:17,080 --> 00:36:19,719 Speaker 1: would have to figure out something about lag and latency 595 00:36:20,080 --> 00:36:24,000 Speaker 1: for these systems. Symnet in a way was a precursor 596 00:36:24,200 --> 00:36:27,640 Speaker 1: to online games that millions of gamers play these days, 597 00:36:27,680 --> 00:36:31,120 Speaker 1: like M M O RPGs. They can kind of trace, 598 00:36:31,360 --> 00:36:34,840 Speaker 1: uh what not necessarily trace their history back. But symnet 599 00:36:35,000 --> 00:36:38,560 Speaker 1: was definitely a precursor to that kind of stuff. There 600 00:36:38,600 --> 00:36:41,840 Speaker 1: are many more technologies the DARPA helped fund In the 601 00:36:41,920 --> 00:36:45,120 Speaker 1: nineteen seventies, there were xemer lasers. These were used in 602 00:36:45,160 --> 00:36:50,680 Speaker 1: communications platforms between aircraft and submerged submarines. They needed to 603 00:36:50,719 --> 00:36:54,480 Speaker 1: develop special lasers in the short wave range of lasers. 604 00:36:54,520 --> 00:36:58,280 Speaker 1: The longer wavelengths didn't have good penetration in the water, 605 00:36:58,520 --> 00:37:02,440 Speaker 1: so you couldn't really use them to communicate with a submarine. 606 00:37:02,600 --> 00:37:05,160 Speaker 1: But there was this need to communicate with submarines because 607 00:37:05,200 --> 00:37:07,719 Speaker 1: at that point, really the only way a submarine could 608 00:37:07,719 --> 00:37:11,480 Speaker 1: communicate with the surface is if the submarine itself surfaced, 609 00:37:11,680 --> 00:37:14,960 Speaker 1: and obviously that puts the submarine in a vulnerable position. 610 00:37:15,480 --> 00:37:19,279 Speaker 1: Being able to use these short wave lasers and have 611 00:37:19,440 --> 00:37:22,040 Speaker 1: them penetrate the water reach the submarine and have the 612 00:37:22,080 --> 00:37:25,640 Speaker 1: submarine be able to respond opened up communication in ways 613 00:37:25,719 --> 00:37:29,239 Speaker 1: that weren't possible before. DARPA also contributed some of the 614 00:37:29,280 --> 00:37:34,320 Speaker 1: components for the Hubble Space Telescope. The agency would design 615 00:37:34,440 --> 00:37:38,800 Speaker 1: and help build two antenna booms for the satellite telescope 616 00:37:38,800 --> 00:37:42,440 Speaker 1: in the late nineteen seventies and early nineties. DARBA pioneered 617 00:37:42,440 --> 00:37:45,480 Speaker 1: the development of a special graphite and aluminum material that 618 00:37:45,480 --> 00:37:48,319 Speaker 1: would allow the booms to not just conduct radio frequencies 619 00:37:48,560 --> 00:37:52,440 Speaker 1: but also double as structural supports. So these structural supports 620 00:37:52,440 --> 00:37:57,440 Speaker 1: that made made the overall telescope lighter. The material was lighter, 621 00:37:57,920 --> 00:38:01,840 Speaker 1: it removes some of the need for some extra infrastructure. 622 00:38:02,360 --> 00:38:05,640 Speaker 1: And again, if you make your payload lighter to send 623 00:38:05,640 --> 00:38:08,960 Speaker 1: off into space, you bring the price down. So weight 624 00:38:09,120 --> 00:38:12,200 Speaker 1: is money, So it was a cost saving feature. It 625 00:38:12,320 --> 00:38:15,520 Speaker 1: took the better part of a decade for DARPA to 626 00:38:15,560 --> 00:38:19,000 Speaker 1: recover in the wake of the Vietnam War. The agency 627 00:38:19,120 --> 00:38:22,400 Speaker 1: changed a lot in the nineteen seventies. And we're gonna 628 00:38:22,480 --> 00:38:26,880 Speaker 1: leave off for now. We're gonna say goodbye to DARPA 629 00:38:26,920 --> 00:38:29,040 Speaker 1: for the time being, but I will come back to 630 00:38:29,080 --> 00:38:31,799 Speaker 1: revisit the agency and the projects that funded over the 631 00:38:31,840 --> 00:38:35,839 Speaker 1: following decades in future episodes. So we'll talk about things 632 00:38:35,840 --> 00:38:39,239 Speaker 1: like star wars and autonomous cars and spying on World 633 00:38:39,320 --> 00:38:42,680 Speaker 1: of Warcraft players and more, because DARPA played a role 634 00:38:42,719 --> 00:38:46,600 Speaker 1: in all of that kind of stuff. It's a fascinating story. 635 00:38:47,080 --> 00:38:52,440 Speaker 1: And again, because of the work that DARPA has helped fund, 636 00:38:52,920 --> 00:38:57,799 Speaker 1: we have access to some pretty incredible technologies that you know, 637 00:38:58,160 --> 00:39:01,160 Speaker 1: rolled out a few years later based on that early work. 638 00:39:02,000 --> 00:39:05,960 Speaker 1: So it's definitely benefited us in many, many ways. The 639 00:39:06,360 --> 00:39:10,719 Speaker 1: agency has also created stuff that's been at best controversial 640 00:39:10,719 --> 00:39:15,600 Speaker 1: and it worst incredibly incredibly harmful, like Agent Orange is 641 00:39:15,840 --> 00:39:20,040 Speaker 1: the one to point to easily as being a truly 642 00:39:20,160 --> 00:39:24,680 Speaker 1: terrible thing. So you take the good, you take the bad, 643 00:39:24,719 --> 00:39:27,000 Speaker 1: you take them both, and there you have DARPA. I 644 00:39:27,080 --> 00:39:30,480 Speaker 1: guess we will revisit this in the future, but in 645 00:39:30,520 --> 00:39:33,560 Speaker 1: the meantime, if you guys have any suggestions for topics 646 00:39:33,560 --> 00:39:35,600 Speaker 1: you would like me to cover on tech Stuff, some 647 00:39:35,640 --> 00:39:38,359 Speaker 1: sort of technology, a company, a person in tech, whatever 648 00:39:38,400 --> 00:39:43,520 Speaker 1: it may be, go to tech Stuff podcast dot com. 649 00:39:43,680 --> 00:39:46,880 Speaker 1: You can find all the ways to contact us there. 650 00:39:47,280 --> 00:39:50,080 Speaker 1: I look forward to hearing from you.
