The engines worked like giant vacuums

Area 51 by Annie JacobsenThe Oxcart’s J-58 jet engines developed by Pratt and Whitney were finally delivered in 1963, Annie Jacobsen explains (in Area 51), but not without complications:

A host of new problems occurred when the engines were first powered up. In one instance, engineers suspected a foreign object was stuck in an engine’s heart, called the power plant, and was damaging internal parts. An X-ray showed the outline of a pen that had fallen into the engine’s cover, called a nacelle, during final assembly in Burbank. From then on, Lockheed workers got coveralls without breast pockets.

[…]

The engines worked like giant vacuums. Once powered up on the tarmac, they sucked in every loose object lying around, including rocks and metal screws. As a solution, Area 51 workers took to sweeping and then vacuuming the runway before each flight. It was a tedious but necessary job.

[…]

As the airplane reached higher speeds, the 500-plus-degree temperatures began melting electrical components, many of which had to be redesigned and rewired.

[…]

In the case of the Oxcart, the sonic shock unexpectedly caused the fuselage to flex in such a way that many structural parts became dangerously compromised. These parts had to be redesigned and replaced.

[…]

Every flight was like an operational mission, with navigators plotting a course and making maps days before as they worked to test the Oxcart’s inertial navigation system, or INS. “When you’re flying at that altitude and that speed, you need big checkpoints to validate information from the INS,” recalls navigator Sam Pizzo. “Any old geographical landmark, like a mountain or a river, would not do. The Oxcart traveled too fast. Pilots would have to look for landmarks on the scale of the Grand Canyon or the Great Lakes,” says the veteran navigator. “You can’t imagine what new territory this was for a navigator. No amount of experience can prepare you when you work on an airplane that goes two or three times as fast as anything you navigated for before.”

Elon Musk by Walter Isaacson An hour before Russia launched its invasion of Ukraine on February 24, 2022, Walter Isaacson explains (in his biography of Elon), it disabled the routers of the American satellite company Viasat with a massive malware attack, which disabled the Ukrainian military’s command and control:

Top Ukrainian officials frantically appealed to Musk for help, and the vice prime minister, Mykhailo Fedorov, used Twitter to urge him to provide connectivity. “We ask you to provide Ukraine with Starlink stations,” he pleaded. Musk agreed. Two days later, five hundred terminals arrived in Ukraine.

[…]

The next day SpaceX sent two thousand more terminals via Poland. But Dreyer said that the electricity was off in some areas, so many of them wouldn’t work. “Let’s offer to ship some field solar+battery kits,” Musk replied. “They can have some Tesla Powerwalls or Megapacks too.” The batteries and solar panels were soon on their way.

[…]

Unlike every other company and even parts of the U.S. military, they were able to find ways to defeat Russian jamming. By Sunday, the company was providing voice connections for a Ukrainian special operations brigade. Starlink kits were also used to connect the Ukrainian military to the U.S. Joint Special Operations Command and to get Ukrainian television broadcasts back up. Within days, six thousand more terminals and dishes were shipped, and by July there were fifteen thousand Starlink terminals operating in Ukraine.

[…]

Starlink contributed about half of the cost of the dishes and services it provided. “How many have we donated so far?” Musk wrote Dreyer on March 12. She replied, “2000 free Starlinks and monthly service. Also, 300 heavily discounted to Lviv IT association and we waived the monthly service for ~5500.” The company soon donated sixteen hundred additional terminals, and Musk estimated its total contribution to be around $80 million.

[…]

Although he had readily supported Ukraine, his foreign policy instincts were those of a realist and student of European military history. He believed that it was reckless for Ukraine to launch an attack on Crimea, which Russia had annexed in 2014. The Russian ambassador had warned him, in a conversation a few weeks earlier, that attacking Crimea would be a red line and could lead to a nuclear response.

[…]

Allowing the use of Starlink for the attack, he concluded, could be a disaster for the world. So he reaffirmed a secret policy that he had implemented, which the Ukrainians did not know about, to disable coverage within a hundred kilometers of the Crimean coast. As a result, when the Ukrainian drone subs got near the Russian fleet in Sevastopol, they lost connectivity and washed ashore harmlessly.

[…]

Musk replied that the design of the drones was impressive, but he refused to turn the coverage for Crimea back on, arguing that Ukraine “is now going too far and inviting strategic defeat.” He discussed the situation with Biden’s national security advisor, Jake Sullivan, and chairman of the joint chiefs, General Mark Milley, explaining to them that SpaceX did not wish Starlink to be used for offensive military purposes. He also called the Russian ambassador to assure him that Starlink was being used for defensive purposes only. “I think if the Ukrainian attacks had succeeded in sinking the Russian fleet, it would have been like a mini Pearl Harbor and led to a major escalation,” Musk says. “We did not want to be a part of that.”

[…]

He took it upon himself to help find an end to the Ukrainian war, proposing a peace plan that included new referenda in the Donbas and other Russian-controlled regions, accepting that Crimea was a part of Russia, and assuring that Ukraine remained a “neutral” nation rather than becoming part of NATO. It provoked an uproar. “Fuck off is my very diplomatic reply to you,” tweeted Ukraine’s ambassador to Germany. President Zelenskyy was a bit more cautious. He posted a poll on Twitter asking, “Which Elon Musk do you like more?: One who supports Ukraine, or One who supports Russia.”

[…]

“SpaceX’s out of pocket cost to enable and support Starlink in Ukraine is ~$80M so far,” he wrote in response to Zelenskyy’s question. “Our support for Russia is $0. Obviously, we are pro Ukraine.” But then he added, “Trying to retake Crimea will cause massive death, probably fail and risk nuclear war. This would be terrible for Ukraine and Earth.”

[…]

Providing humanitarian help was fine, but private companies should not be financing a foreign country’s war. That should be left to the government, which is why the U.S. has a Foreign Military Sales program that puts a layer of protection between private companies and foreign governments. Other companies, including big and profitable defense contractors, were charging billions to supply weapons to Ukraine, so it seemed unfair that Starlink, which was not yet profitable, should do it for free. “We initially gave the Ukrainians free service for humanitarian and defense purposes, such as keeping up their hospitals and banking systems,” she says. “But then they started putting them on fucking drones trying to blow up Russian ships. I’m happy to donate services for ambulances and hospitals and mothers. That’s what companies and people should do. But it’s wrong to pay for military drone strikes.”

[…]

An agreement was struck that the Pentagon would pay SpaceX $145 million to cover the service.

But then the story leaked, igniting a backlash against Musk in the press and Twitterverse. He decided to withdraw his request for funding. SpaceX would provide free service indefinitely for the terminals that were already in Ukraine. “The hell with it,” he tweeted. “Even though Starlink is still losing money & other companies are getting billions of taxpayer $, we’ll just keep funding Ukraine govt for free.”

Shotwell thought that was ridiculous. “The Pentagon had a $145 million check ready to hand to me, literally. Then Elon succumbed to the bullshit on Twitter and to the haters at the Pentagon who leaked the story.”

[…]

“Starlink was not meant to be involved in wars. It was so people can watch Netflix and chill and get online for school and do good peaceful things, not drone strikes.”

[…]

More than 100,000 new dishes were sent to Ukraine at the beginning of 2023. In addition, Starlink launched a companion service called Starshield, which was specifically designed for military use. SpaceX sold or licensed Starshield satellites and services to the U.S. military and other agencies, allowing the government to determine how they could and should be used in Ukraine and elsewhere.

Area 51 by Annie JacobsenAfter Oxcart pilot Kenneth Collins’ experimental spy plane crashed, Annie Jacobsen explains (in Area 51), the CIA redoubled its efforts to keep the project secret:

Declassified in 2007 and never before made public, the CIA had been monitoring phone conversations of journalists who seemed interested in the Oxcart program. “Mr. Marvin Miles, Aviation Editor, Los Angeles Times, telephonically contacted Westinghouse Corp., Pittsburgh, attempting to confirm if employees of that firm were traveling covertly to ‘the desert’ each week in connection with top secret Project which he suspects may have ‘CIA’ association,” read one memo. Another stated that “Mr. Robert Hotz, Editor Aviation Week, indicated his awareness of developments at Burbank.” Of particular concern to the Agency was an article in the Hartford Courant that referred to the “secret development” of the J-58 engine. Another article in the Fontana, California, paper the Herald News speculated about the existence of Area 51, calling it a “super secret Project site.” An increasingly suspicious CIA worked overtime to monitor journalists, and they also monitored regular citizens, including a Los Angeles–based taxi driver who was described in a memo marked “classified” as once having asked a Pratt and Whitney employee if he was “en route to Nevada.”

The Agency should have been more concerned about its rival:

Just as it had with the U-2, the Pentagon moved in on the CIA’s spy plane territory. Only with the Oxcart, the Air Force ordered not one but three Air Force variants for its stable. One version, the YF-12A, would be used as an interceptor aircraft, its camera bay retrofitted to hold two 250-kiloton nuclear bombs. The second Oxcart variant the Air Force ordered could carry a drone on its back. The third was a two-seater version of the CIA’s stealth spy plane, only instead of being designed to conduct high-speed, high-altitude reconnaissance missions over enemy territory during peacetime, the Air Force supersonic spy plane was meant to go in and take pictures of enemy territory immediately after a nuclear strike by U.S. bomber planes—to see if any strategic targets had been missed. Designated the RS-71 Blackbird, this now-famous aircraft had its letter designation accidentally inverted by President Lyndon B. Johnson in a public speech. Since the president is rarely ever “corrected,” the Air Force changed its letter designation, which is how the SR-71 Blackbird got its name. (Originally, the letters stood for “Reconnaissance/ Strike.”)

[…]

The Air Force had already spent eight hundred million dollars developing the B-70 bomber airplane — a massive, triangle-shaped, Mach 3, six-engined bomber that had been General LeMay’s passion project since its inception in 1959. When a fleet of eighty-five of these giant supersonic bombers was first proposed to Congress, LeMay, then head of the Strategic Air Command, had his proposition met with cheers. But the Gary Powers shoot-down in May of 1960 had exposed the vulnerability of LeMay’s B-70 bombers, which would fly at the same height as the U-2. In 1963 LeMay was no longer head of the Strategic Air Command — instead, he was President Kennedy’s Air Force chief of staff. Despite evidence showing the B-70 bomber was not a practical airplane, LeMay was not about to give up his beloved bomber without a fight.

When the CIA first briefed President Kennedy on how high and how fast the A-12 Oxcart would fly, the president was astonished. His first question, according to CIA officer Norman Nelson, was “Could it be converted into a long-range bomber to replace the B-70?” LeMay was in the room when Kennedy asked the question. The thought of losing his pet program to the Agency drove General LeMay wild. He lobbied the Pentagon to move forward with the B-70, and he stepped up his public relations campaign, personally promoting the B-70 bomber program in magazine interviews from Aviation Week to Reader’s Digest. He was committed to appealing to as many Americans as possible, from aviation buffs to housewives. But by 1963, Kennedy was leaning toward canceling the B-70. In a budget message, he called it “unnecessary and economically unjustifiable.” Congress cut back its B-70 order even further. The original order for eighty-five had already been cut down to ten, and now Congress cut that to four.

[…]

“Johnson, I want a promise out of you that you won’t lobby anymore against the B-70,” LeMay said. Provided Kelly Johnson complied, LeMay promised to send Lockheed an Air Force purchase order for an interceptor version of Lockheed’s A-12 Oxcart, in addition to the preexisting order. For Lockheed, this would mean a big new invoice to send to the Air Force. At first, Kelly Johnson was suspicious of LeMay’s sincerity. That changed just a few weeks later when Secretary of Defense Robert McNamara showed up at the Skunk Works with the secretary of the Air Force and the assistant secretary of defense in tow. Now McNamara asked for a briefing on the A-12, during which he took “copious notes.” Within a matter of months, the Pentagon ordered twenty-five more A-12 variants. The Pentagon already had a catchy name for its versions of the Oxcart. They would call them Blackbirds. Black because they had been developed in the dark by the CIA, and birds because they could fly.

[…]

The CIA did all of the heavy lifting to get the aircraft aloft, only to have the program eventually taken over by the Pentagon for the Air Force.

Collins submitted to a far less conventional way of seeking out the truth of the cause of the crash

Saturday, August 24th, 2024

Area 51 by Annie JacobsenOxcart pilot Kenneth Collins was taking the experimental spy plane out for a subsonic test run, like a race horse out for a trot, Annie Jacobsen explains (in Area 51), when something went wrong:

“Suddenly, the altimeter was rapidly unwinding, indicating a rapid loss of speed,” Collins recalls. In heavy clouds, Collins had no visual references to determine where he was. “I advanced the throttles to counter the loss of airspeed. But instead of responding, and without any warning, the aircraft pitched up and flipped over with me trapped underneath. Then it went into an inverted flat spin.” The Agency’s million-dollar A-12 Oxcart was unrecoverable and crashing. Collins needed to bail out.

Collins had no idea how close he was to the Earth’s surface because he was in the middle of a cloud and couldn’t see out of it. He also did not know if he was over a mountain range, which would mean he had even less time to eject. Collins closed his visor and grabbed the ejection ring that was positioned between his legs. He pushed his head firmly against the headrest and pulled. This kind of radical ejection from a prized top secret aircraft is not easy to forget, and Collins recalls dramatic details. “The canopy of the aircraft flew off and disappeared but I was still upside down, with the aircraft on top of me,” he explains. “Having pulled the D-ring, my boot stirrups snapped back. The explosive system in the seat rocket engaged, shooting me downward and away from the aircraft.” First Collins separated from the Oxcart. Next he separated from his seat. After that, he was a body falling through the air until a small parachute called a drogue snapped open, slowing his body down. In his long history of flying airplanes, this was the first time Collins had ever had to bail out. Falling to Earth, he tried to get a sense of what state he might be over. Was he in Nevada or Utah? The ground below him appeared to be high-desert terrain, low hills but no mountains that he could see. He was still too high up to discern if there were roads. As he floated down, in the distance he spotted the heavy black aircraft tumbling through the air until it disappeared from sight. “I remember seeing a large, black column of smoke rise up from the desert floor and thinking, That’s my airplane.” Only now there was nothing left of it but an incinerated hunk of titanium smoldering on the ground. Fate was a hunter, all right.

[…]

Collins unclipped himself from the parachute and began collecting everything around him. Flight-protocol pages and filmstrips of navigational maps fluttered across the desert. As he hurried to collect the top secret papers, he was surprised to hear a car motor in the distance. Looking up, he saw a pickup truck bouncing toward him along a dirt desert road. “As it got closer, I could see there were three men in the front cab,” Collins recalls. “The truck pulled alongside me and came to a stop. I could see they had my aircraft canopy in the back of their pickup.”

The men, who appeared to be local ranchers, sized up Collins. Because the flight had been subsonic, Collins was wearing a standard flight suit and not a high-altitude pressure suit, which would have made him look like an astronaut or an alien and likely prompted a lot more questions. Instead, the ranchers asked Collins if he wanted a ride. They said they knew exactly where his airplane had crashed, and if he hopped in, they’d give him a ride back to his plane. Until that moment, no civilian without a top secret security clearance had ever laid eyes on the Oxcart, and Collins had strict orders to keep it that way. He’d been briefed on what to do in a security breach such as this one, given a cover story by the Agency that fit perfectly with the proximity to the Nevada Test Site—and with the times. Collins told the ranchers that his aircraft was an F-105 fighter jet and that it had a nuclear weapon on board. The men’s expressions changed from helpful to fearful. “They got very nervous and said if I wanted a ride, I better jump in quick because they were not staying around Wendover for long,” Collins recalls.

The ranchers drove Collins to the nearest highway patrol office. There, he jumped out, took his airplane canopy from the back of the truck, and watched the men speed off. Collins reached into the pocket of his flight suit. Inside, he found the note that read call this number, followed by a telephone number. Also in his pocket was a dime. Inside the highway patrol office, Collins asked the officer on duty where he could find the nearest pay phone. The man pointed around to the side of the building, and using the Agency’s dime, Collins made the phone call that no Agency pilot ever wants to make. A little less than an hour later, Kelly Johnson’s private airplane landed in Wendover, Utah, along with several men from the CIA. After a brief exchange of words so Kelly Johnson could confirm that Collins was physically okay, Collins boarded the airplane. During the two-hour flight to the Lovelace Clinic in New Mexico, no one said a word. “There would be plenty of talking to do during the debriefing,” Collins says, “and with the Agency’s tape recorders taking everything down.” A crash of a CIA spy plane meant someone had some explaining to do.

[…]

“Maintenance guys, security guys, navigators, we all took off in trucks and airplanes and headed to Utah,” Pizzo explains. With Collins confirmed alive, the goal now was to locate every single piece of the wrecked airplane, “every nut, bolt, and sliver of fuselage.”

[…]

Once they found the site, the work crew had a lot of digging to do. The aircraft, Article #123, hadn’t broken apart in flight, but given the speed at which it had hit the earth, huge sections of the airplane had become buried. Critically important was locating every loose piece of the titanium fuselage. The metal was rare and expensive, and the fact that the Agency’s spy plane was hand-forged from titanium was a closely held secret. If a news reporter or a local got a hold of even the smallest piece of the aircraft, its unusual composition would raise questions that might threaten the cover of the entire Oxcart program. Equally critical to national security was making sure the radar-absorbing materials, known as composite and that covered the entire airplane, remained in government control. If a piece of the plane got into the wrong hands, the results could be disastrous: the Russians could learn the secret of stealth.

Along with a crew of more than one hundred men, the Agency brought its own horses to the crash site. Men from Groom Lake took to the desert terrain on horseback and began their search.

[…]

In Air Force culture, when an airplane crashes, someone has to take the blame. Collins explains: “In the SAC [Strategic Air Command] mind-set, if there’s an accident, the wing commander suffers the consequences.” Instead, Collins believes, Holbury tried to get Collins to be the fall guy. “Holbury didn’t want blame; he wanted a star. He wanted to become a general, so he tried to put the blame on me. After the crash, even before the investigation, he requested that I be fired.”

Collins was unwilling to accept that. Fortunately for Collins’s career, Kelly Johnson, the builder of the aircraft, didn’t care about blame as much as he wanted to find out what had gone wrong with his airplane. Listening to Collins describe what had happened during the debriefing, Johnson couldn’t figure out what caused the aircraft to crash. He wondered if there was something Collins had forgotten, or was maybe leaving out. “I was clear in my mind that the crash was a mechanical error and not a pilot error,” Collins explains. “So when Kelly Johnson asked would I try unconventional methods like hypnosis and truth serum, I said yes. I was willing to do anything I could to get to the truth.” While the Pentagon’s accident board conducted a traditional investigation, Collins submitted to a far less conventional way of seeking out the truth of the cause of the crash.

Inside the flight surgeon’s office at Lockheed, Collins sat with a CIA-contracted hypnotist from Boston, “a small, rotund man dressed in a fancy suit,” as Collins recalls. “He tried very hard to put me in a trance, only it didn’t work. I don’t think he realized that hypnotizing a fighter pilot was not as easy as he thought it might be.” Next, Collins was injected with sodium thiopental, also known as truth serum. Collins remembers the day well. “I told my wife, Jane, I was going to work for a few hours, which was unusual to begin with because it was a Sunday. The point of the treatment was to see if I could remember details other than those I relayed in the original debrief with the CIA. But yes, even with the sodium pentothal in my system, everything I said was exactly the same. The treatment takes a lot out of you and after it was over, I was very unsteady on my feet. Three CIA agents brought me home late that Sunday evening. One drove my car, the other two carried me inside and laid me down on the couch. I was still loopy from the drugs. They handed Jane the car keys and left without saying a word.”

[…]

After a lengthy investigation it was determined that a tiny, pencil-size part called a pitot tube had in fact caused the crash. The pitot tube measured the air coming into the aircraft and thereby controlled the airspeed indicator. Unlike in a car, where the driver can feel relative speed, in a plane, without a proper reading from an airspeed indicator, a pilot has no awareness of how fast he is going, and without correct airspeed information a pilot cannot land. When Collins flew into the cloud, the pitot tube reacted adversely to the moisture inside and froze. The false airspeed indicator caused the aircraft to stall. As a result of the stall, the Oxcart flipped upside down and crashed.

FPV drones generally require a radio link to the operator

Tuesday, August 20th, 2024

Russia is striking back against the Kursk offensive with new drones guided by fiber optics which are immune to radio jamming:

FPV drones generally require a radio link to the operator. This transmits a video signal from the drone, and command signals to the drone on another channel. Loss of either signal usually means an instant crash.

This is why we have seen a profusion of trench jammers, suitcase jammers and vehicle -mounted jammers on the front lines, blasting out radio noise on selected frequencies. If effective they create a bubble of protection reaching out fifty or a hundred yards. This will generally keep FPVs away, although skilled FPV operators approach at a steep angle so their drone gets through on sheer momentum.

Drones keep changing their operating frequencies and jammers keep being updated to stop them in an unending cat-and-mouse game. This is why it takes a blitz like the one in Kursk, with a prolonged period of preparation to identify all the frequencies in use and the concentration enough jammers to block everything in a given area to strop all drones for a time.

Drones can also lose their link for other reasons. The radio link essentially requires over line of sight. This is fine when the drone is well above ground, but as soon as it dips low, communication starts to break up. Flying relays help, but FPVs have to dive low during the final attack, and there is almost always interference in the video signal in the last second which impair the view at the critical moment.

If you’ve watched a few FPV drone videos, you’ve seen the static right before impact. (They’re analog feeds, typically.)

When I first learned about TOW missiles — “Tube-launched, Optically tracked, Wire-guided” — I was incredulous that a missile spooled out a wire along the way, a three kilometer-long wire. The design goes back a ways:

Late in World War II, the German Army began experimenting with modified versions of the Ruhrstahl X-4 wire-guided missile. Originally developed for the Luftwaffe as an anti-bomber weapon, by changing the warhead to one using a high-explosive anti-tank (HEAT) design, the new X-7 version made an effective anti-armor weapon with a range of hundreds of metres. This would greatly improve the effectiveness of infantry anti-tank operations, which at that time were generally based on smaller weapons like the Panzerfaust and Panzerschreck, limited in the best case to ranges on the order of 150 metres (490 ft). X-7 was never fully developed before the war ended.

These newer FPV drones spool out fiber-optic cable, which carries a high-resolution video signal:

On August 12th videos on social media showed what were claimed to be attacks Ukrainian BTR-4 reconnaissance vehicles in Giri with fiber-optic FPV drones. While this is impossible to confirm, the video show an unusual lack of interference.

[…]

The company Skywalker Technology is now offering fiber-optic drone controllers on the open market. The company website gives a contact address in Singapore, although ClashReport describe them as Chinese.

Skywalker sell a number of drones with military applications including one armed with rockets and another kamikaze type, plus devices to convert consumer quadcopters into bombers. Their latest offering is a fiber-optic guidance set to replace radio control. As with previous designs, it comes with a considerable weight penalty; a 5 km/ 3 miles cable reel weighs about two and a half pounds. Maximum range is six miles, HIGHCAT offers twice that.

As with other FPV components which are commonly sourced from Far Eastern suppliers, this opens up an instant supply of new technology to both parties in the Ukraine conflict. Whereas previously military technology went through a process of evaluation, specification, testing, approval and acquisition taking years, independent drone makers can now buy off the shelf and ship drones to the front in weeks.

The most commonly raised objections – snagging on obstacles, the cable breaking, leaving a trail back to the operator – do not appear to be real issues, but fiber-optic control does have downsides as previously discussed and is unlikely replace radio control entirely. This type will be effective in situations of intense jamming though and might be used in the first wave of an attack.

Fate is a hunter

Saturday, August 17th, 2024

Area 51 by Annie JacobsenAfter surviving the Korean War, Annie Jacobsen explains (in Area 51), Oxcart pilot Kenneth Collins returned with a fatalistic attitude:

“Fate is a hunter,” Collins believes. “When it comes for you, it comes,” and for whatever reason it was not time for death to come to him yet. This was a notion Collins formulated during the Korean War while flying reconnaissance missions and watching so many talented and brave fellow pilots die. How else but by fate did he survive all 113 combat missions he had flown? On those classified missions, the young Collins was armed with only a camera in the nose of his airplane as he flew deep into North Korea, sometimes all the way over the Yalu River, being fired at by MiG fighter jets. During the war, he was awarded a Distinguished Flying Cross and also the coveted Silver Star for valor, the third-highest military decoration a member of the armed services can receive. Both medals were pinned on Collins’s chest before he turned twenty-four.

[…]

Accepting fate as the hunter made things easier for Collins, which is how he dealt with the memory of his closest friend and former wingman from the Fifteenth Tactical Reconnaissance Squadron, Charles R. “Chuck” Parkerson. The two men had flown on many missions together, but there was one from which Parkerson never came home. “We had flown into North Korea and back out side by side,” Collins recalls. “We were almost home when Parkerson radioed me. He said the engine on his RF-80 had flamed out and he was unable to restart it. I saw he was losing altitude quickly and he knew that soon he would crash.” Parachuting into enemy territory meant certain death. “Over the radio, Parkerson asked me, ‘What should I do?’” Collins explains. “I said, ‘Fly out over the Yellow Sea and I’ll fly with you.’ I told him to bail out in the water and I’d send his coordinates back to base for a rescue team.” It seemed like a good idea, and Collins flew alongside his wingman as they headed toward the Yellow Sea. Parkerson prepared for a bailout. “But there was a problem,” Collins recalls. “The canopy on Parkerson’s RF-80 was stuck. Jammed. It wouldn’t open, which meant he was trapped inside the airplane. There was nothing I could do for my friend except to fly alongside him all the way until the end.” Collins watched Parkerson land his airplane on the sea. With Parkerson unable to get out of the sinking aircraft, Collins waited, watching from the air as his friend drowned. “When your time is up, it is up,” Collins recalls.

Only to reemerge from his defrocking by Big Tech as a vengeance-seeking icon of counterelite Americana

Wednesday, August 14th, 2024

Palmer Luckey sounds like a fictional character:

Luckey is the owner of the world’s largest video game collection, which he keeps buried 200 feet underground in a decommissioned U.S. Air Force nuclear missile base — which is the kind of thing a man can afford to buy when he single-handedly turns virtual reality from the laughingstock of the technology industry into a multi-billion-dollar enterprise by inventing the Oculus Rift in a camper trailer parked in the driveway of his parents’ duplex in Long Beach, California, where at 19 years old he lived alone and survived on frozen burritos and Mucho Mango AriZona tea.

[…]

After selling Oculus to Facebook for $2.7 billion and then getting fired by Mark Zuckerberg for making a $10,000 donation to a pro-Trump troll group dedicated to “shitposting in real life,” Luckey tried his hand at building a nonprofit private prison chain that only gets paid when ex-prisoners stay out of prison. After he decided that would require too much lobbying work, he attempted to solve the obesity epidemic by making food out of petroleum products centrifuged out of the sewer system — a perfectly delicious and low-calorie idea, he maintains, which he only ditched because of the “marketing nightmare” of persuading people to eat remanufactured sewage. In the end, he decided instead to found Anduril Industries, a defense technology startup that makes lethal autonomous weapons systems. It is now valued at $14 billion.

[…]

In his spare time, when he is not providing U.S. Customs and Border Patrol with AI-powered long-range sensors, or Volodymyr Zelenskyy with drones to attack high-value Russian targets, or winning first place in the Texas Renaissance Festival’s costume contest with historically meticulous renderings of Henry VIII and Anne Boleyn sewn and stitched by his wife, Nicole—who’s been at his side for 16 of his 31 years on earth — Luckey recently built a bypass for his peripheral nervous system to experiment with giving himself superhuman reflexes; vestibular implants to pipe sounds into his skull so that instead of having to call him and wait for him to pick up, Anduril employees could just pick up a designated Palmer Phone and talk straight into his head; and a virtual reality headset that — by tying three explosive charges to a narrow-band photosensor that can detect when the screen flashes red at a specific frequency (i.e., GAME OVER) — kills you in real life when you die in a video game.

[…]

Before the recent preference cascade enabling high-profile tech moguls to violate the taboo against supporting Donald Trump, there was first the lonely figure of Palmer Luckey, the homeschooled, Jules Verne-obsessed, amateur scientist with no money, whose faith in the power of technology was so strong that he worked jobs sweeping ship yards, scrubbing decks, fixing engines, repairing phones, and training to sing as a gondolier for tourists, all in order to spend his nights in a gutted 19-foot camper trailer trying to manufacture dream worlds out of breadboards and lens equipment and accelerometers and magnetometers and a soldering iron — which he did, bringing virtual reality to the masses, burning a hole in his retina with a laser, and losing it all to Zuckerberg over a meme, only to reemerge from his defrocking by Big Tech as a vengeance-seeking icon of counterelite Americana, the aspiring rebuilder of the arsenal of democracy, the black mullet-, chin beard-, Hawaiian shirt-, cargo short-, sandal-clad possible savior of America.

Two of the installers succumbed to the heat

Monday, August 12th, 2024

Elon Musk by Walter IsaacsonWhen Musk turned his attention to SolarCity, Walter Isaacson explains (in his biography of Elon), there were consequences:

He fired his cousins, who had focused on door-to-door sales schemes rather than making a good product. “I fucking hate my cousins,” he told Kunal Girotra, one of the four chiefs of Tesla Energy he hired and fired over the subsequent five years. “I don’t think I ever will ever speak to them again.”

He cycled through leaders by demanding miraculous growth in roof installations, giving them insane deadlines for delivering, and firing them when they didn’t.

[…]

There were too many fasteners, he said. Each had to be nailed down, adding time to the installation process. Half should be deleted, he insisted. “Instead of two nails for each foot, try it with only one,” he ordered. “If the house has a hurricane, the whole neighborhood is fucked up, so who cares? One nail is going to be fine.” Someone protested that could lead to leaks. “Don’t worry about making it as waterproof as a submarine,” he said. “My house in California used to leak. Somewhere between sieve and submarine should be okay.”

[…]

The tiles and railings were shipped to the sites packed in cardboard. That was wasteful. It took time to pack things and then unpack them. Get rid of the cardboard, he said, even at the warehouses.

[…]

“We need to get the engineers who designed this system to come out here and see how hard it is to install,” he said angrily. Then he erupted. “I want to see the engineers out here installing it themselves. Not just doing it for five minutes. Up on roofs for days, for fucking days!”

[…]

Why, he asked, did it take eight times longer to install a roof of solar tiles than one with regular tiles? One of the engineers, named Tony, began showing him all the wires and electronic parts. Musk already knew the workings of each component, and Tony made the mistake of sounding both assured and condescending. “How many roofs have you done?” Musk asked him.

“I’ve got twenty years of experience in the roof business,” Tony answered.

“But how many solar roofs have you installed?”

Tony explained he was an engineer and had not actually been on a roof doing the installation. “Then you don’t fucking know what you’re fucking talking about,” Musk responded. “This is why your roofs are shit and take so long to install.”

[…]

At high noon the next day, it reached 97 degrees in the shade, of which there was none. Dow and his installers were on top of the house next door to the one they had done the previous day. Two of the installers succumbed to the heat and started vomiting, so Dow sent them home. Some of the rest attached battery fans to their safety vests. Per Musk’s instructions, they were using only one nail to hold down each foot of the tiles, but it wasn’t working well. The tiles were popping up and rotating. So the team began using two nails again.

[…]

When Musk arrived at 9 p.m., they showed him why they needed a second nail, and he nodded. It was part of the algorithm: if you don’t end up having to restore 10 percent of the parts you deleted, then you didn’t delete enough.

[…]

“Nice work, guys,” he said. “You should stopwatch each step. That will make it more fun, like a game.”

I asked him about his anger the previous evening. “It’s not my favorite way to fix things, but it worked,” he says. “The improvement from yesterday to today was gigantic. The big difference is that today the engineers were actually on the roof installing instead of at a keyboard.”

[…]

The business of installing solar roofs is labor-intensive and doesn’t scale.

[…]

Musk did not have the patience for such businesses.

[…]

“You’ve got to cut costs,” he said. “You’ve got to show me a plan by next week to cut costs in half.” As before, Dow showed his enthusiasm. “Okay, let’s do it,” he said. “We’ll kick ass and cut costs.”

He spent all weekend working on a cost-cutting plan to present to Musk that Monday. But as soon as the meeting began, Musk changed the subject and grilled Dow about how many installations had been completed in the past week and details about personnel redeployments. Dow did not know some of the answers, and he protested that he had been working since his birthday on cost-cutting plans and not the details Musk was now asking about. “Thank you for trying,” Musk finally said. “But this isn’t cutting it.”

It took Dow a while to realize that Musk was firing him. “It was just the most bizarre, weird firing you could imagine,” Dow later says. “I had so much history with him, and deep down Elon knows that I have something special. He knows that I can kick ass, because we’d done it together in the past, in the Nevada battery factory. But he thought I was losing my edge, even though I had missed my birthday with my family to be up on that roof with him.”

The pressure-suit officers could gauge how tough a flight was

Saturday, August 10th, 2024

Area 51 by Annie JacobsenAt Area 51, Annie Jacobsen explains (in Area 51), Oxcart pilot Kenneth Collins went by the code name Ken Colmar:

“Same first name because you will instantly respond to it when called,” Collins explains. “Colmar for the C, in case you had something monogrammed.” His call sign was Dutch 21 but most men on base called him the Iceman. The pressure-suit officers came up with the nickname. “I was known to show no emotion or irritation even after a particularly dangerous flight,” Collins recalls. The pressure-suit officers could gauge how tough a flight was by how sweaty a pilot’s underwear was when they helped pilots undress. Collins’s underwear was always remarkably dry.

[…]

Having a stable marriage and family had become a CIA-pilot mandate during Oxcart, something that was not in place during the U-2. It was Gary Powers’s alcoholic wife who’d triggered the change. Some in the Agency believed she put the secrecy of the entire U-2 program at risk with behavior that even they could not control. Once, Barbara Powers got it into her head to visit her husband at his clandestine post in Turkey. She made it as far as Athens before the officer assigned to watch her notified Powers that he would be out of a job if he couldn’t keep his impetuous wife in line. Ken Collins was told this story during his first interview at the Pentagon. Loose lips didn’t just sink ships, he was reminded; loose lips could trigger nuclear war.

[…]

Each Monday morning, Collins left his home and drove to Burbank Airport, nine miles to the southwest. There, he and the other Oxcart pilots climbed aboard Constellation propeller planes and headed to Area 51, never with more than two pilots per airplane—a guideline put into place after the Mount Charleston crash eight years earlier. The deaths of those top Agency and Air Force managers and scientists had set progress on the U-2 program back several months.

[…]

The appearance of a new, moonlike subsidence crater was often a weekly occurrence now that nuclear testing had moved underground. When seen from above, the landscape at the Nevada Test Site looked like a battlefield after the apocalypse.

[…]

During training missions, the papers in Collins’s flight pouch identified him only as a NASA weather pilot. His space-age-looking aircraft was registered to an airfield called Watertown Strip, Nevada. He was never to carry any personal effects with him in the airplane. When the Lockheed Constellation landed on the tarmac at Area 51, security guards took his ID and papers and locked them away in a metal box. Each Friday, before the afternoon flight home, Collins’s identity was returned to him.

Palantir’s CTO has good taste in books

Wednesday, August 7th, 2024

This Kind of War by T.R. FehrenbachAxios recently interviewed Palantir’s CTO and asked, “What are you currently reading, or what’s a book you’d recommend?”

I’m in the midst of “This Kind of War,” a classic about the Korean War. The book I read right before that, which I would highly recommend, is Annie Jacobsen’s “Nuclear War.”

I suppose I’ll get around to sharing my thoughts on Nuclear War, but loyal readers of the blog will know that This Kind of War earned a lot of attention here.

2.9 billion hit in one of the largest data breaches ever

Wednesday, August 7th, 2024

The personal data of 2.9 billion people — full names, addresses going back 30 years, and Social Security Numbers — was stolen from National Public Data by a group that goes by the name USDoD:

The complaint goes on to explain that the hackers then tried to sell this huge collection of personal data on the dark web to the tune of $3.5 million.

[…]

So how does a firm like National Public Data obtain the personal data of almost 3 billion people? The answer is through scraping which is a technique used by companies to collect data from web sites and other sources online.

What makes the way National Public Data did this more concerning is that the firm scraped personally identifiable information (PII) of billions of people from non-public sources. As a result, many of the people who are now involved in the class action lawsuit did not provide their data to the company willingly.

Physics does not care about hurt feelings

Elon Musk by Walter IsaacsonA few weeks after the surge, Walter Isaacson explains (in his biography of Elon), Musk turned his attention to Raptor, the engine that would power Starship:

Fueled by supercooled liquid methane and liquid oxygen, it had more than twice the thrust of the Falcon 9’s Merlin engine. This meant that Starship would have more thrust than any other rocket in history.

[…]

Raptor was too complex to be mass-manufactured. It looked like a spaghetti bush. So in August 2021, Musk fired the person in charge of its design and personally took on the title of vice president for propulsion. His goal was to get the cost of each engine to around $200,000, a tenth of what it then cost.

[…]

Musk began with his lecture on collegiality. “I want to be super clear,” he began. “You are not the friend of the engineers. You are the judge. If you’re popular among the engineers, this is bad. If you don’t step on toes, I will fire you. Is that clear?” Hughes stuttered a bit as he assented.

Ever since he flew back from Russia and calculated the costs of building his own rockets, Musk had deployed what he called the “idiot index.” That was the ratio of the total cost of a component to the cost of its raw materials. Something with a high idiot index — say, a component that cost $1,000 when the aluminum that composed it cost only $100 — was likely to have a design that was too complex or a manufacturing process that was too inefficient. As Musk put it, “If the ratio is high, you’re an idiot.”

“What are the best parts in Raptor as judged by the idiot index?” Musk asked.

“I’m not sure,” Hughes responded. “I will find out.” This was not good. Musk’s face hardened, and Shotwell shot me a worried glance.

“You better be fucking sure in the future you know these things off the top of your head,” Musk said. “If you ever come into a meeting and do not know what are the idiot parts, then your resignation will be accepted immediately.” He spoke in a monotone and showed no emotion. “How can you fucking not know what the best and worst parts are?”

“I know the cost chart down to the smallest part,” Hughes said quietly. “I just don’t know the cost of the raw materials of those parts.”

“What are the worst five parts?” Musk demanded. Hughes looked at his computer to see if he could calculate an answer. “NO! Don’t look at your screen,” Musk said.

“Just name one. You should know the problematic parts.”

“There’s the half nozzle jacket,” Hughes offered tentatively.

“I think it costs thirteen thousand dollars.”

“It’s made of a single piece of steel,” Musk said, now quizzing him. “How much does that material cost?”

“I think a few thousand dollars?” replied Hughes.

Musk knew the answer. “No. It’s just steel. It’s about two hundred bucks. You have very badly failed. If you don’t improve, your resignation will be accepted. This meeting is over. Done.”

[…]

“We should ask each of them to see if they can get the cost of their part down by eighty percent,” Musk suggested, “and if they can’t, we should consider asking them to step aside if someone else might be able to do so.”

By the end of the meeting, they had a roadmap to get the cost of each engine down from $2 million to $200,000 in twelve months.

[…]

“I give people hardcore feedback, mostly accurate, and I try not to do it in a way that’s ad hominem,” he says. “I try to criticize the action, not the person. We all make mistakes. What matters is whether a person has a good feedback loop, can seek criticism from others, and can improve. Physics does not care about hurt feelings. It cares about whether you got the rocket right.”

[…]

He thinks that when people want to prioritize their comfort and leisure they should leave.

That’s what Hughes did in May 2022. “Working for Elon is one of the most exciting things you can do, but it doesn’t allow time for a lot else in your life,” he says. “Sometimes that’s a great trade. If Raptor becomes the most affordable engine ever created and gets us to Mars, then it may be worth the collateral damage. That’s what I believed for more than eight years. But now, especially after the death of our baby, it’s time for me to focus on other things in life.”

[…]

“It’s like Machiavelli taught,” Krebs replied. “You have to have fear and love for the leader. Both.”

That attitude would sustain Krebs for another two years. But by Spring 2023, he would become another refugee from Musk’s hardcore all-in approach. After getting married and having a child, he decided it was time to move on and find a better work-life balance.

The Ukrainian Ministry of Defense has not always been efficient in providing the best equipment

Thursday, August 1st, 2024

Swarm Troopers by David HamblingNear the end of his 2015 book Swarm Troopers, David Hambling notes that “there has been conflict in the east of Ukraine since 2014”:

Militias in Russian-speaking eastern Ukraine, apparently with covert backing from Russia, have been fighting against government forces. The Ukrainian Ministry of Defense has not always been efficient in providing the best equipment; critics say that the procurement process is managed badly and undermined by corruption. Ukrainian forces needed drones for reconnaissance and surveillance on the front line. When they could not get them through official channels, they took procurement into their own hands.

The Aerorozvidka project and the People’s Project are both devoted to making up the Ukrainian drone shortfall. Using private money — and in the case of the People’s Project, crowdfunding — they have adapted commercial drones for battlefield operations. At the larger end of the scale, the PD-1 “People’s Drone” is a fixed-wing craft with a ten-foot wingspan and a pusher propeller. Many of the other drones are simply commercial models like the DJI Phantom supplied by supporters in the US.

[…]

The Ukrainians fit their drones with improved communications, as their opponents have access to effective Russian jammers and have jammed both drone communications and GPS navigation signals. They have also learned to be careful about placement of communication antennas when controlling the drones, and the need for controllers to keep moving. On two occasions, their drone operators have been hit by mortar fire when the Russians pinpointed them by their radio signals.

The Ukrainian drones can find and track the enemy and direct artillery fire in real time. Aerorozvidka even claims to be working on drones armed with homemade missiles.

Any Western soldier who has to expose themselves to enemy fire during reconnaissance may well wonder why they do not have access to the same small drones as the Ukrainians.

Why is no one working?

Sunday, July 28th, 2024

Elon Musk by Walter Isaacson”The storm clouds building in his head burst,” Walter Isaacson explains (in his biography of Elon), when Musk and a group of his top managers went down the road to the launchpad site and didn’t see anybody working:

This might not have seemed unusual to most people on a late Friday night, but Musk erupted. His immediate target was a tall, mild-mannered civil engineer named Andy Krebs, who was in charge of building the infrastructure at Starbase. “Why is no one working?” Musk demanded.

Unfortunately for Krebs, it was the first time in three weeks he didn’t have a full night shift working on the tower and launchpad. Soft-spoken with a hint of a stutter, he was tentative in his answers, which didn’t help. “What is the fucking problem?” Musk demanded. “I want to see activity.”

That’s when he ordered the surge. Starship’s booster and second stage, he said, should be rolled out of the manufacturing bays and stacked on the launchpad within ten days. He wanted five hundred workers from around SpaceX—Cape Canaveral, Los Angeles, Seattle—to be flown immediately to Boca Chica and thrown into the breach. “This is not a volunteer organization,” he said. “We are not selling Girl Scout cookies. Get them here now.” When he called Gwynne Shotwell, who was in bed in Los Angeles, to figure out what workers and supervisors would come to Boca Chica, she protested that the engineers at the Cape still had Falcon 9 launches to prepare for. Musk ordered them delayed. The surge was his priority.

Shortly after 1 a.m., Musk sent out an email titled “Starship Surge” to all SpaceX employees. “Anyone who is not working on other obviously critical path projects at SpaceX should shift immediately to work on the first Starship orbit,” he wrote. “Please fly, drive, or get here by any means possible.”

At Cape Canaveral, Kiko Dontchev, who won his spurs when Musk ignited a similar frenzy after seeing almost no one working on Pad 39A one night, began rousing his best workers to fly to Texas. Musk’s assistant Jehn Balajadia tried to get hotel rooms in nearby Brownsville, but most were booked for a border-control convention, so she scrambled to make arrangements for workers to sleep on air mattresses. Sam Patel worked through the night figuring out the reporting and supervising structures they would put in place—and also how to get enough food to Boca Chica to feed everyone.

[…]

The surge was successful. In just over ten days, the booster and spacecraft of Starship were stacked on the launchpad. It was also a bit pointless. The rocket was not yet capable of flying, and stacking it did not force the FAA to rush its approval. But the ginned-up crisis pushed the team to remain hardcore, and it provided Musk with a bit of the drama that his headspace craves.

GPS jamming looks more like a weapon for a swarm attacking an urban target rather than as a way of stopping a swarm

Thursday, July 25th, 2024

Swarm Troopers by David HamblingEver since radios have been used in warfare, David Hambling explains (in Swarm Troopers), there have been efforts to interfere with them:

Britain’s Royal Navy experimented with broadcasting signals to interfere with enemy communication as far back as 1902, just five years after the first radios were installed on ships. By WWI, the use of radio was more sophisticated, and so were countermeasures. The German Zeppelins used fixes from radio stations to navigate; so on the night of 19 October 1917, the French switched radio broadcasts from the Eiffel Tower to another station to send the airships off course. When the Germans started using their own transmitters for navigation, the Allies drowned these out with louder transmissions on the same wavelength, possibly the first attempt to deliberately jam radio reception.

[…]

The first radio-guided weapon to see action was the German FS-1400 or Fritz-X developed in WWII. This was a three-thousand-pound glide bomb designed to attack heavily armored battleships and cruisers. It was a simple bomb fitted with small fins worked by radio control. A flare on the tail of the bomb allowed the bomb aimer to follow its progress and adjust its course with simple up-down, left-right corrections.

[…]

The Allies captured Fritz-X missiles and control equipment, and had developed effective countermeasures within a matter of months.

The British Type 650 Transmitter, and jammers from the US Naval Research Laboratory and Harvard’s Radio Research Laboratory, nullified the Fritz-X. The jammer steered the bomb as far over in one direction as possible, overriding the operator’s commands. From being a guaranteed hit, it became a guaranteed miss. The Germans dropped the idea of radio guidance, and the next version of the Fritz-X was guided via a wire spooling out of the back of the missile.

[…]

At its simplest, jamming may simply mean broadcasting noise in the frequency band that the receiver is operating in. This sort of brute force jamming is rare in military circles, where communications tend to hop from one frequency to another at rapid intervals, and it is difficult to jam the entire spectrum with enough power. Smart jammers detect and analyze an opponent’s communications and can selectively jam only in the ranges where needed. Jammers are also likely to be directional, rather than blasting out noise in all directions.

In the Iraq and Afghan conflicts, tactical jamming took on a new urgency. Insurgents had started triggering bombs using cheap cell phones. Special countermeasures were fielded to block the signals; the Pentagon spent some $17 billion on electronic countermeasures with some fifty thousand jamming units being issued. These included portable Warlock Green units for foot soldiers, which are credited with saving many lives.

[…]

It is notable that the 2014 Black Dart exercise included an EA-18 Growler, the most modern electronic warfare aircraft in the Air Force’s inventory, equipped with a range of powerful jammers. When the radio signal to a drone is jammed, it is usually programmed to return to the last point where it could communicate or simply return to base.

[…]

There is a growing interest in free-space optical communications, sometimes described as “like broadband over optical fiber, but without the fiber.” The laser signal is beamed through the air to the receiver. This method only works over line of sight (obviously enough) and, because of atmospheric effects, the range tends to be limited to a mile or so. It can carry as much data as a broadband fiber optic cable and would be ideal for a swarm of drones forming a mesh network. Because it does not rely on radio waves, optical communication cannot be jammed or hacked into.

In a more low-tech version of optical communication, researchers at the Postgraduate Naval Center in Monterey have looked at communicating via QR codes as a form of “digital semaphore.”

[…]

The team found that QR codes could be read from over five hundred feet away. A swarm could pass messages between members to coordinate its actions.

[…]

An artillery shell is out of control as soon as it leaves the barrel, as is a heat-seeking missile when it leaves the rails. Some missiles, designed to target air defense radar, already pick their own targets. The distinction between controlled and uncontrolled is subtler than you might expect.

[…]

If blocking communications does not work, we can try another weak point, navigation. A human pilot has many ways of finding their way around, but most drones only have GPS. The power of the Global Positioning System’s signal has been compared to a car headlight over ten thousand miles away, making it an easy signal to jam.

However, anti-jamming measures are getting better. Raytheon has developed a sophisticated anti-jam device for GPS called Landshield built around a controlled pattern reception antenna. This has an array of receiving elements that combine to cancel out the jamming from any given direction. When a jamming signal is detected, the array automatically nulls it out. It is like looking through a cardboard tube so you can see a faint light in the distance without being dazzled by lights nearby.

Raytheon’s previous generation of anti-jam GPS was the Advanced Digital Antenna Platform, which weighed about ten pounds and was the size of a telephone directory. The new Landshield fits on a silicon chip and may be integrated with military GPS devices, from portable units used by individual soldiers to the GPS-guided Paveway bomb and, of course, drones.

[…]

On Monday, 22 January 2007, an electronic warfare exercise being carried out in San Diego harbor accidentally jammed GPS signals across the city. Disruption started almost immediately. The emergency paging system at a hospital stopped functioning. The automated harbor traffic management system stopped working, threatening to throw the port into chaos. Air traffic control at San Diego airport reported problems with their system for tracking incoming aircraft. Some bank ATMs reportedly stopped giving out money.

The reason for this disruption is that many modern systems use the precision time signal from GPS satellites. In some cell phone networks the signal is used to give each mast a unique identity; if it is lost, the mast drops off the network. GPS timing signals time-stamp financial transactions to prevent fraud, and this may be why the cash machines stopped working. Power utilities use the GPS time signal to keep alternating current from different power plants in phase across the grid. If this is lost, then attempts to switch power supplies to channel power to where it is needed become inefficient as the out-of-phase currents clash. This may ultimately produce blackouts.

GPS jamming looks more like a weapon for a swarm attacking an urban target rather than as a way of stopping a swarm.

This vulnerability is one reason why alternatives to GPS are a hot topic. One such is the system developed by Australian company Locata. This uses a network of ground-based ‘pseudo-satellites’ which give a more accurate fix and would require vastly more powerful jammers to block.

[…]

You can already navigate urban areas without GPS thanks to Wi-Fi. Each Wi-Fi hotspot has its own fingerprint, including a Service Set ID and Media Access Control address, and transmits them continuously. Service providers including Google and Navizon map out the location of each node; by identifying those closest to you, you can pinpoint your location within less than a hundred feet.

Other researchers are navigating using “signals of opportunity,” including not only Wi-Fi but cell phone signals, radio and television transmitters, and other sources of radio waves. These may not be as accurate as GPS, but they can be used indoors as well as out, and cannot be stopped except by jamming absolutely everything.

[…]

Tomahawk cruise missiles were originally equipped with terrain-matching radar to compare the scenery with an electronic landscape map to determine their location. The difference now is that every smartphone has the storage and processing power to scan the scenery and find out where it is.
