How Lockheed Martin Designed the World's Weirdest, Quietest Supersonic Jet (fastcompany.com) 77

An anonymous reader quotes a report from Fast Company: The Lockheed Martin X-59 is probably the strangest airplane ever designed. Its razor-sharp nose takes half of the airplane's length; there's no cockpit in sight; the wings are tiny compared to the entire fuselage; and its oversized tail engine looks like a weird hump about to fall off. Of course, there's a method to this madness. The design is the secret sauce that has produced a true unicorn: a supersonic jet that doesn't boom the hell out of people and buildings on the ground. [...] The X-59, developed alongside NASA, is designed as an experimental jet that NASA will use to test just how big of a boom people on the ground are willing to accept from a supersonic aircraft. According to Dave Richardson, the program director for X-59 at Lockheed Martin, with this new design, people shouldn't expect much of a boom at all.

The X-59's "quiet" supersonic boom isn't made possible by expensive magical materials or exotic engines, Richardson explains. "There is no radical technology in the airplane itself. It really is just the shape of the aircraft." And if the shape looks more like an anime alien spaceship than an actual vehicle created by human beings, that's because it was dreamed up in another dimension -- by computers and humans -- through special software created by the Bethesda, Maryland, company's engineers. [...] Richardson and his team learned a few important lessons about designing for supersonic boom. First, the heavy, bulky parts of the plane needed to be as far back as possible. "We really put nothing out in the front, but we want to have that long, fine ratio," he says. This resulted in an extremely fine nose and body, with no surface interruptions that can produce noise when the plane breaks the sound barrier. "You want to be able to stretch out and manage the different shocks across the length of the airplane," he adds.

They also learned that anything that causes discontinuity in the airplane's shape -- for instance a windshield or canopy -- can add to the boom effect. This led them to get rid of the windshield altogether. Instead, the X-59 uses an external vision system, which is the only advanced technology in the plane, according to Richardson. The pilot navigates using a camera, viewing the outside through a large display. This system had to undergo rigorous certification by the Federal Aviation Administration for use in the national airspace. [...] The X-59 has been designed to manage and distribute shockwaves differently from the very start while also flying at slower speeds than the Concorde (the Concorde's cruising speed was 1,350 mph, while the X-59 will cruise at around 925 mph). "I think most people look at the airplane and they say, 'Wait, something's wrong,'" Richardson says. "[They think] it's too long. The landing gear is too far in the back. And why is the nose so long?"
The inaugural flight is scheduled for early 2024, notes Fast Company. "If they achieve their objectives, there's no reason why aircraft manufacturers can't take the concepts they discovered and turn them into commercial airliners, Richardson says."

"Someday, people might be able to look up and see an alien shape in the sky, with the X-59's design transcending experimental nature and ushering in a new era for high-speed travel across the globe."

Air Force Receives Its First Electric Air Taxi (nytimes.com) 32

An anonymous reader quotes a report from the New York Times: The Air Force said on Monday that it had received its first electric passenger aircraft capable of taking off and landing vertically, a milestone for the companies that hope to one day sell thousands of such vehicles to serve as air taxis. Joby Aviation, an air taxi start-up, delivered the aircraft to Edwards Air Force Base in Southern California, where the first supersonic flight took place. Air taxis are typically powered by batteries and designed to lift off and land like helicopters, but include wings to fly like airplanes. Joby, which is based in Santa Cruz, Calif., said that its electric aircraft is substantially quieter than helicopters or planes. Each can carry one pilot and four passengers and travel as fast as 200 miles per hour and as far as 100 miles, according to the company.

The delivery is the first under an Air Force contract that Joby said was valued at up to $131 million and gives the government the option to receive up to nine aircraft. The Air Force and Joby will operate the vehicle, but Joby will still own the aircraft and receive both fixed and variable payments for hours flown. NASA, which has a facility at the base, will also conduct research on the vehicle. The Air Force has signed similar contracts with other air taxi companies under a program called Agility Prime, part of a broader effort to promote innovation. Agility Prime's mission is to support development of air taxis and similar technology, giving the Air Force a head start in exploring how it might use such aircraft while also providing financial and testing support to the air taxi companies.

At Edwards Air Force Base, Joby's aircraft will be tested as a means to transport cargo and people. The vehicles could also be used to monitor the expansive base or tested to conduct medical evacuations, for example. All told, the Air Force has more than 100 performance measures it wants to evaluate, said Beau Griffith, the deputy lead of Agility Prime. "Bearing out the promise of these vehicles is the program's goal," he said. NASA will work closely with the military and Joby in testing the aircraft, with the aim of using its research to guide air taxi development and support the F.A.A. Starting next year, NASA pilots and researchers will explore how Joby's vehicle would operate in a typical city environment, examining flight procedures and how it could interact with air traffic control and local infrastructure. Joby's aircraft is expected to remain at the base for at least a year, and the company has plans to deliver another in 2024.

US Exploring Potential Space Force Hotline With China (reuters.com) 43

The United States Space Force reportedly discussed setting up a hotline with China to prevent crises in space, according to Reuters, citing U.S. commander General Chance Saltzman. From the report: The chief of space operations said a direct line of communication between the Space Force and its Chinese counterpart would be valuable in de-escalating tensions but that the U.S. had not yet engaged with China to establish one. "What we have talked about on the U.S. side at least is opening up a line of communication to make sure that if there is a crisis, we know who we can contact," Saltzman said, adding that it would be up to President Joe Biden and the State Department to take the lead on such discussions. The U.S. Space Force, founded in 2019, also does not have a direct line of communication with its Russian counterpart.

Los Alamos's New Project: Updating America's Aging Nuclear Weapons (apnews.com) 192

During World War II, "Los Alamos was the perfect spot for the U.S. government's top-secret Manhattan Project," remembers the Associated Press.

"The community is facing growing pains again, 80 years later, as Los Alamos National Laboratory takes part in the nation's most ambitious nuclear weapons effort since World War II." The mission calls for modernizing the arsenal with droves of new workers producing plutonium cores — key components for nuclear weapons. Some 3,300 workers have been hired in the last two years, with the workforce now topping more than 17,270. Close to half of them commute to work from elsewhere in northern New Mexico and from as far away as Albuquerque, helping to nearly double Los Alamos' population during the work week... While the priority at Los Alamos is maintaining the nuclear stockpile, the lab also conducts a range of national security work and research in diverse fields of space exploration, supercomputing, renewable energy and efforts to limit global threats from disease and cyberattacks...

The headline grabber, though, is the production of plutonium cores. Lab managers and employees defend the massive undertaking as necessary in the face of global political instability. With most people in Los Alamos connected to the lab, opposition is rare. But watchdog groups and non-proliferation advocates question the need for new weapons and the growing price tag... Aside from pressing questions about the morality of nuclear weapons, watchdogs argue the federal government's modernization effort already has outpaced spending predictions and is years behind schedule. Independent government analysts issued a report earlier this month that outlined the growing budget and schedule delays.

"A hairline scratch on a warhead's polished black cone could send the bomb off course..." notes an earlier article.

"The U.S. will spend more than $750 billion over the next 10 years replacing almost every component of its nuclear defenses, including new stealth bombers, submarines and ground-based intercontinental ballistic missiles in the country's most ambitious nuclear weapons effort since the Manhattan Project."

US Defense Department Funds Design Analysis for a Transportable Micro Nuclear Reactor (defense.gov) 120

America's Department of Defense recently exercised a contract option with X-energy, a private nuclear reactor engineering company, seeking "a thorough analysis of design options" for a transportable micro nuclear reactor. The Department says its ultimate goal is "a reactor design which is ready for licensing by the Nuclear Regulatory Commission for both commercial ventures and military resiliency."

Their announcement also notes that additional work is already underway by another company, BWX Technologies, on a prototype micro reactor: "Due to their extraordinary energy density, nuclear reactors have the potential to serve multiple critical functions for meeting resiliency needs in contested logistical environments," said Dr. Jeff Waksman, Project Pele program manager. "By developing two unique designs, we will provide the Services with a broad range of options as they consider potential uses of nuclear power for both Installation and Operational energy applications in the near future."

The Defense Department uses approximately 30 Terawatt-hours of electricity per year and more than 10 million gallons of fuel per day — levels that are only expected to increase due to anticipated electrification of the vehicle fleet and maturation of future energy-intensive capabilities. A safe, small, transportable nuclear reactor would address this growing demand with a resilient, carbon-free energy source that does not add to the Defense Department's fuel needs, while supporting mission-critical operations in remote and austere environments...

"The Strategic Capabilities Office specializes in adapting commercial technology for military purposes," said Jay Dryer, director. "By nurturing and developing multiple micro reactor designs, SCO will not just provide options for the military Services, but will also help jumpstart a truly competitive commercial marketplace for micro reactors."

China's Quest for Human Genetic Data Spurs Fears of a DNA Arms Race (adn.com) 32

In 2020 Serbian scientists were gifted China's "Fire-Eye" labs, remembers the Washington Post. The sophisticated portable labs "excelled not only at cracking the genetic code for viruses, but also for humans, with machines that can decipher genetic instructions contained within the cells of every person on Earth, according to its Chinese inventors."

Although some of them were temporary, "scores" of the portable labs "were donated or sold to foreign countries during the pandemic," reports the Washington Post. But it adds that now those same labs "are attracting the attention of Western intelligence agencies amid growing unease about China's intentions." Some analysts perceive China's largesse as part of a global attempt to tap into new sources of highly valuable human DNA data in countries around the world. That collection effort, underway for more than a decade, has included the acquisition of U.S. genetics companies as well as sophisticated hacking operations, U.S. and Western intelligence officials say. But more recently, it received an unexpected boost from the coronavirus pandemic, which created opportunities for Chinese companies and institutes to distribute gene-sequencing machines and build partnerships for genetic research in places where Beijing previously had little or no access, the officials said. Amid the pandemic, Fire-Eye labs would proliferate quickly, spreading to four continents and more than 20 countries, from Canada and Latvia to Saudi Arabia, and from Ethiopia and South Africa to Australia. Several, like the one in Belgrade, now function as permanent genetic-testing centers...

BGI Group, the Shenzhen-based company that makes Fire-Eye labs, said it has no access to genetic information collected by the lab it helped create in Serbia. But U.S. officials note that BGI was picked by Beijing to build and operate the China National GeneBank, a vast and growing government-owned repository that now includes genetic data drawn from millions of people around the world. The Pentagon last year officially listed BGI as one of several "Chinese military companies" operating in the United States, and a 2021 U.S. intelligence assessment linked the company to the Beijing-directed global effort to obtain even more human DNA, including from the United States. The U.S. government also has blacklisted Chinese subsidiaries of BGI for allegedly helping analyze genetic material gathered inside China to assist government crackdowns on the country's ethnic and religious minorities...

Beijing's drive to sweep up DNA from across the planet has occasionally stirred controversy, particularly after a 2021 Reuters series about aspects of the project. Chinese academics and military scientists have also attracted attention by debating the feasibility of creating biological weapons that might someday target populations based on their genes. Genetic-based weapons are regarded by experts as a distant prospect, at best, and some of the discussion appears to have been prompted by official paranoia about whether the United States and other countries are exploring such weapons.

U.S. intelligence officials believe China's global effort is mostly about beating the West economically, not militarily. There is no public evidence that Chinese companies have used foreign DNA for reasons other than scientific research. China has announced plans to become the world's leader in biotechnology by 2035, and it regards genetic information — sometimes called "the new gold" — as a crucial ingredient in a scientific revolution that could produce thousands of new drugs and cures...

U.S. intelligence officials said in interviews that they have limited insight into how BGI handles DNA information acquired overseas, including whether genetic data from the Fire-Eye labs ultimately end up in the computers of China's military or intelligence services... Chinese law makes clear that any information collected using BGI's machines can be accessed by the Chinese government. A national intelligence law enacted in 2017 stipulates that Chinese firms and citizens are legally bound to share proprietary information acquired in foreign countries whenever requested.

US Asks for Help Finding Missing F-35 Fighter Jet After Crash (bloomberg.com) 103

The United States' military is on the hunt for an F-35 fighter jet that has gone missing following an incident that forced the pilot to eject from the advanced stealth aircraft over South Carolina. Bloomberg News: Emergency response teams are trying to find what's left of the F-35B Lightning II jet, which suffered what the military called a "mishap" on Sunday afternoon, according to social media posts by Joint Base Charleston, an air base in South Carolina. The unidentified pilot ejected safely and was taken to a local hospital in a stable condition. Joint Base Charleston called on the public to cooperate with military and civilian authorities as the search for the F-35 jet continues. The air base said it was working with Marine Corps Air Station Beaufort to search for the plane north of North Charleston around Lake Moultrie and Lake Marion, based on its last-known location.

Lockheed Martin is the manufacturer behind the F-35, a single-seat fighter craft used by militaries around the world. The aircraft was a vertical take-off version used by in the US Marine Corps, and the jet is popular for its stealth qualities that make it difficult to detect by radar. The F-35 program, the most expensive US weapons program ever, is projected to cost $400 billion in development and acquisition, plus an additional $1.2 trillion to operate and maintain the fleet over more than 60 years. Each jet can cost more than $160 million, depending on the variant.

China's Spy Balloon Program Appears to Have Been Suspended, US Officials Say (cnn.com) 81

An anonymous reader shared this report from CNN: China appears to have suspended its surveillance balloon program following a major diplomatic incident earlier this year, when one of the country's high-altitude spy balloons transited the United States, multiple sources familiar with US intelligence assessments told CNN. US officials believe that Chinese leaders have made a deliberate decision not to launch additional balloons since the one over the US was shot down by American fighter jets in February, the sources said. The US has not observed any new launches since the episode occurred... The US intelligence community believes that Chinese Communist Party leaders did not intend for the balloon to cross over the United States, and even reprimanded the operators of the surveillance program over the incident, one of the sources said...

The US assessed at the time that the spy balloon was part of an extensive surveillance program run by the Chinese military, CNN has previously reported. The balloon fleet had conducted at least two dozen missions over at least five continents in recent years, according to US officials. The suspension of the program is likely China's way of trying to stabilize its relations with the United States in the run-up to a potential meeting between President Biden and Xi in November at the Asia-Pacific Economic Cooperation summit in San Francisco, said Christopher Johnson, a former senior China analyst at the CIA and now a senior fellow at the Center for Strategic and International Studies. Although China is unlikely to publicly acknowledge that the balloon was part of an espionage program or announce it will no longer conduct such surveillance on the United States, Johnson said, quietly suspending the program is "a positive step" and likely Beijing's way of showing the US it is trying to address some of the friction points in the relationship...

The FBI concluded its analysis of the balloon's remnants earlier this year, and the Pentagon announced in June that the US government assessed that the balloon did not collect intelligence while flying over the country...In the wake of the incident, the US widened the aperture of its radar systems so that they could better detect objects traveling above a certain altitude and at certain speeds. The aim was to fix a "domain awareness gap" that had allowed three other suspected Chinese spy balloons to transit the continental United States undetected under the Trump administration, Gen. Glen VanHerck, commander of US Northern Command and North American Aerospace Defense Command, said at the time. The more sensitive radar systems led the US military to spot more unidentified objects in US airspace, however, leading to three additional shootdowns of unidentified high-altitude objects in the weeks following the Chinese balloon incident.

Firefly Aerospace Sets Launch Speed Record For US Space Force (space.com) 28

An anonymous reader quotes a report from Space.com: Firefly Aerospace just set a new responsive-launch record. The company's Alpha rocket lifted off from Vandenberg Space Force Base on Thursday (Sept. 14) at 10:28 p.m. EDT (7:28 p.m. local California time; 0228 GMT on Sept. 15), kicking off a mission for the U.S. Space Force called Victus Nox. The rocket roared off the pad just 27 hours after the U.S. Space Force gave the order -- less time than on any previous national security mission. The wheels for Victus Nox (Latin for "conquer the night") began turning in September 2022, when the Space Force awarded contracts to Texas-based Firefly and Millennium Space Systems, a Boeing subsidiary headquartered in the Los Angeles area that built the mission's payload.

On Aug. 30 of this year, Firefly and Millennium entered the mission's "hot standby" phase, a six-month period during which they could receive a launch-alert notice at any time. After receipt of that notice, Millennium and Firefly would have 60 hours to get the satellite from Millennium's Southern California facilities to Vandenberg, fuel it up and mate it to the Alpha rocket's payload adapter. The alert came through recently, and the mission teams hit their ambitious timeline. "Upon activation, the space vehicle was transported 165 miles [266 kilometers] from Millennium's El Segundo facility to Vandenberg Space Force Base where it was tested, fueled and mated to the launch adapter in just under 58 hours, significantly faster than the typical timeline of weeks or months," Space Force officials said in the emailed statement.

The teams then had to wait for the launch order, which would give them Victus Nox's orbital requirements. They would then have just 24 hours to update Alpha's trajectory and guidance software, encapsulate the satellite in its payload fairing, get the payload to the pad, mate it to Alpha and get the rocket ready to launch, Firefly wrote in a statement. The teams managed that task as well. They were ready to launch as soon as the first window opened, which was 27 hours after the Space Force gave the order. Victus Nox's speed goals didn't end with the successful liftoff. The teams now aim to get the satellite up and running within 48 hours of its deployment.
The report notes that the previous response-launch record for a U.S. national security mission was 21 days, which was set in June 2021.

North American Airspace Defense Getting Cloud-Based Backbone Next Month 26

The cloud-based system the Air Force is co-developing with Canada to enable instantaneous combat data-sharing is just about ready for prime time, although the looming threat of a budget gap may slow its global deployment. The Drive reports: Cloud-based command-and-control (CBC2), a pillar of the service's Advanced Battle Management System (ABMS), will hit initial operating capability roughly on schedule next month, Brig. Gen. Luke Cropsey, integrating program officer for Command, Control, Communications and Battle Management, told The War Zone and other outlets this week at the Air, Space, and Cyber conference near Washington, D.C. It's headed to three unspecified base locations within the first half of 2024, Cropsey said, with others to follow at "more scale" as what's anticipated to be a five-year rollout plan gets underway. [...] CBC2 is designed to replace the hardware-based Battle Control System-Fixed, which provides command-and-control for Canada and the U.S., including Alaska and Hawaii. Officially made a program in 2022, CBC2 is "a set of microservice applications," according to an Air Force release, that can take in more than 750 radar feeds and deliver them to a single user interface. "The system then allows operators to create machine-generated courses of action to help shorten the tactical C2 kill chain and send a desired effect via machine-to-machine connections," the release adds.

In addition to delivering data faster and streamlining communication, CBC2 will build in new artificial intelligence elements. A January Government Accountability Office report states that it will build upon Pathfinder, an AI-empowered prototype that ingests "data that would in the past have been ... left on the cutting room floor," as North American Aerospace Defense Command chief Gen. Glen VanHerck put it in remarks reported by C4ISRNet. A September 2020 paper (PDF) from the Canada Institute described Pathfinder as "giving new life to old sensors" for NORAD's defense. "In a recent demonstration," the paper stated, "The Pathfinder system was tied to Federal Aviation Administration radars, and without any modification to the radars themselves, consistently demonstrated an ability to effectively detect and track very small unmanned aircraft, previously thought to be beyond the capability of the system."

Pentagon Plans Vast AI Fleet To Counter China Threat (wsj.com) 60

The Pentagon is considering the development of a vast network of AI-powered technology, drones and autonomous systems within the next two years to counter threats from China and other adversaries. WSJ: Kathleen Hicks, the deputy secretary of defense, will provide new details in a speech later Wednesday about the department's plans to spend hundreds of millions of dollars to develop an array of thousands of air-, land- and sea-based artificial-intelligence systems that are intended to be "small, smart, cheap."

The U.S. is seeking to keep pace with China's rapidly expanding military amid concerns that the Pentagon bureaucracy takes too long to develop and deploy cutting-edge systems. [...] One approach could be to build on the capabilities demonstrated by Task Force 59, the U.S. Navy's network of drones and sensors designed to monitor Iran's military activities in the Middle East.

US Spy Agency Dreams of Surveillance Underwear (theintercept.com) 82

The future of wearable technology, beyond now-standard accessories like smartwatches and fitness tracking rings, is ePANTS, according to the intelligence community. The Intercept: The federal government has shelled out at least $22 million in an effort to develop "smart" clothing that spies on the wearer and its surroundings. Similar to previous moonshot projects funded by military and intelligence agencies, the inspiration may have come from science fiction and superpowers, but the basic applications are on brand for the government: surveillance and data collection. Billed as the "largest single investment to develop Active Smart Textiles," the SMART ePANTS -- Smart Electrically Powered and Networked Textile Systems -- program aims to develop clothing capable of recording audio, video, and geolocation data, the Office of the Director of National Intelligence announced in an August 22 press release. Garments slated for production include shirts, pants, socks, and underwear, all of which are intended to be washable.

The project is being undertaken by the Intelligence Advanced Research Projects Activity, the intelligence community's secretive counterpart to the military's better-known Defense Advanced Research Projects Agency, or DARPA. IARPA's website says it "invests federal funding into high-risk, high reward projects to address challenges facing the intelligence community." Its tolerance for risk has led to both impressive achievements, like a Nobel Prize awarded to physicist David Wineland for his research on quantum computing funded by IARPA, as well as costly failures. "A lot of the IARPA and DARPA programs are like throwing spaghetti against the refrigerator," Annie Jacobsen, author of a book about DARPA, "The Pentagon's Brain," told The Intercept. "It may or may not stick."

Russia Targets Ukraine With New Android Backdoor, Intel Agencies Say (arstechnica.com) 24

An anonymous reader quotes a report from Ars Technica: Russia's military intelligence unit has been targeting Ukrainian Android devices with "Infamous Chisel," the tracking name for new malware that's designed to backdoor devices and steal critical information, Western intelligence agencies said on Thursday. "Infamous Chisel is a collection of components which enable persistent access to an infected Android device over the Tor network, and which periodically collates and exfiltrates victim information from compromised devices," intelligence officials from the UK, US, Canada, Australia, and New Zealand wrote (PDF). "The information exfiltrated is a combination of system device information, commercial application information and applications specific to the Ukrainian military."

Infamous Chisel gains persistence by replacing the legitimate system component known as netd with a malicious version. Besides allowing Infamous Chisel to run each time a device is restarted, the malicious netd is also the main engine for the malware. It uses shell scripts and commands to collate and collect device information and also searches directories for files that have a predefined set of extensions. Depending on where on the infected device a collected file is located, netd sends it to Russian servers either immediately or once a day. When exfiltrating files of interest, Infamous Chisel uses the TLS protocol and a hard-coded IP and port. Use of the local IP address is likely a mechanism to relay the network traffic over a VPN or other secure channel configured on the infected device. This would allow the exfiltration traffic to blend in with expected encrypted network traffic. In the event a connection to the local IP and port fails, the malware falls back to a hard-coded domain that's resolved using a request to dns.google.

Infamous Chisel also installs a version of the Dropbear SSH client that can be used to remotely access a device. The version installed has authentication mechanisms that have been modified from the original version to change the way users log in to an SSH session. [...] The report didn't say how the malware gets installed. In the advisory Ukraine's security service issued earlier this month (PDF), officials said that Russian personnel had "captured Ukrainian tablets on the battlefield, pursuing the aim to spread malware and abuse available access to penetrate the system." It's unclear if this was the vector.

Pentagon Bets On Quick Production of Autonomous Systems To Counter China (politico.com) 114

Under an ambitious program, dubbed Replicator, the Pentagon aims to field thousands of autonomous systems within two years to counter China. The effort is being spearheaded by Deputy Defense Secretary Kathleen Hicks. Politico reports: Hicks said the time is right to push to rapidly scale up innovative technology. The move comes as the U.S. looks to get creative to deter China in the Indo-Pacific and Pentagon leadership has taken stock of how Ukraine has fended off Russia's invasion. "Industry is ready. The culture is ready to shift," Hicks said. "We have to drive that from the top, and we need to give it a hard target." "The great paradox of military innovation is you're going to have to make big bets and you've got to execute on those bets," she added.

With Replicator, the Pentagon aims to have thousands of autonomous systems across various domains produced and delivered in 18 to 24 months. Hicks declined to discuss what specific platforms might be produced under the program -- such as aerial drones or unmanned ships -- citing the "competition landscape" in the defense industry as well as concerns about tipping DOD's hand to China. The Pentagon will instead "say more as we get to production on capabilities."

Autonomous weapons are seen as a potential way to counter China's numerical advantages in ships, missiles and troops in a rapidly narrowing window. Fielding large numbers of cheap, expendable drones, proponents argue, is faster and lower-cost than exquisite weapons systems and puts fewer troops at risk. Another major aim of the Replicator initiative is to provide a template for future efforts to rapidly field military technology. She said lessons from the Replicator program could be applied throughout the Pentagon, military services and combatant commands.

US Air Force Tests an AI -Powered Drone Aircraft Prototype (msn.com) 65

An anonymous reader shared this report from the New York Times: It is powered into flight by a rocket engine. It can fly a distance equal to the width of China. It has a stealthy design and is capable of carrying missiles that can hit enemy targets far beyond its visual range. But what really distinguishes the Air Force's pilotless XQ-58A Valkyrie experimental aircraft is that it is run by artificial intelligence, putting it at the forefront of efforts by the U.S. military to harness the capacities of an emerging technology whose vast potential benefits are tempered by deep concerns about how much autonomy to grant to a lethal weapon.

Essentially a next-generation drone, the Valkyrie is a prototype for what the Air Force hopes can become a potent supplement to its fleet of traditional fighter jets, giving human pilots a swarm of highly capable robot wingmen to deploy in battle. Its mission is to marry artificial intelligence and its sensors to identify and evaluate enemy threats and then, after getting human sign-off, to move in for the kill... The emergence of artificial intelligence is helping to spawn a new generation of Pentagon contractors who are seeking to undercut, or at least disrupt, the longstanding primacy of the handful of giant firms who supply the armed forces with planes, missiles, tanks and ships. The possibility of building fleets of smart but relatively inexpensive weapons that could be deployed in large numbers is allowing Pentagon officials to think in new ways about taking on enemy forces.

It also is forcing them to confront questions about what role humans should play in conflicts waged with software that is written to kill...

The article adds that the U.S. Air Force plans to build 1,000 to 2,000 AI drones for as little as $3 million apiece. "Some will focus on surveillance or resupply missions, others will fly in attack swarms and still others will serve as a 'loyal wingman' to a human pilot....

"A recently revised Pentagon policy on the use of artificial intelligence in weapons systems allows for the autonomous use of lethal force — but any particular plan to build or deploy such a weapon must first be reviewed and approved by a special military panel."

China Keeps Buying Hobbled Nvidia Cards To Train Its AI Models (arstechnica.com) 20

The US acted aggressively last year to limit China's ability to develop artificial intelligence for military purposes, blocking the sale there of the most advanced US chips used to train AI systems. From a report: Big advances in the chips used to develop generative AI have meant that the latest US technology on sale in China is more powerful than anything available before. That is despite the fact that the chips have been deliberately hobbled for the Chinese market to limit their capabilities, making them less effective than products available elsewhere in the world. The result has been soaring Chinese orders for the latest advanced US processors. China's leading Internet companies have placed orders for $5 billion worth of chips from Nvidia, whose graphical processing units have become the workhorse for training large AI models.

The impact of soaring global demand for Nvidia's products is likely to underpin the chipmaker's second-quarter financial results due to be announced on Wednesday. Besides reflecting demand for improved chips to train the Internet companies' latest large language models, the rush has also been prompted by worries that the US might tighten its export controls further, making even these limited products unavailable in the future. However, Bill Dally, Nvidia's chief scientist, suggested that the US export controls would have greater impact in the future. "As training requirements [for the most advanced AI systems] continue to double every six to 12 months," the gap between chips sold in China and those available in the rest of the world "will grow quickly," he said.

Why DARPA Hopes To 'Distill' Old Binaries Into Readable Code (theregister.com) 54

Researchers at Georgia Tech have developed a prototype pipeline for the Defense Advanced Research Projects Agency (DARPA) that can "distill" binary executables into human-intelligible code so that it can be updated and deployed in "weeks, days, or hours, in some cases." The work is part of a five-year, $10 million project with the agency. The Register reports: After running an executable through the university's "distillation" process, software engineers should be able to examine the generated HAR, figure out what the code does, and make changes to add new features, patch bugs, or improve security, and turn the HAR back into executable code, says GT associate professor and project participant Brendan Saltaformaggio. This would be useful for, say, updating complex software that was written by a contractor or internal team, the source code is no longer or never was to hand and neither are its creators, and stuff needs to be fixed up. Reverse engineering the binary and patching in an update by hand can be a little hairy, hence DARPA's desire for something a bit more solid and automatic. The idea is to use this pipeline to freshen up legacy or outdated software that may have taken years and millions of dollars to develop some time ago.

Saltaformaggio told El Reg his team has the entire process working from start to finish, and with some level of stability, too. "DARPA sets challenges they like to use to test the capabilities of a project," he told us over the phone. "So far we've handled every challenge problem DARPA's thrown at us, so I'd say it's working pretty well." Saltaformaggio said his team's pipeline disassembles binaries into a graph structure with pseudo-code, and presented in a way that developers can navigate, and replace or add parts in C and C++. Sorry, Java devs and Pythonistas: Saltaformaggio tells us that there's no reason the system couldn't work with other programming languages, "but we're focused on C and C++. Other folks would need to build out support for that." Along with being able to deconstruct, edit, and reconstruct binaries, the team said its processing pipeline is also able to comb through HARs and remove extraneous routines. The team has also, we're told, baked in verification steps to ensure changes made to code within hardware ranging from jets and drones to plain-old desktop computers work exactly as expected with no side effects.

US Space Force Creates First Unit Dedicated To Targeting Adversary Satellites (space.com) 57

The United States Space Force has activated its first and only unit dedicated to targeting other nations' satellites and the ground stations that support them. Space.com reports: The 75th Intelligence, Surveillance and Reconnaissance Squadron (ISRS) was activated on Aug. 11 at Peterson Space Force Base in Colorado. This unit is part of Space Delta 7, an element of the U.S. Space Force tasked with providing intelligence on adversary space capabilities. It'll do things like analyze the capabilities of potential targets, locate and track these targets as well as participate in "target engagement," which presumably refers to destroying or disrupting adversary satellites, the ground stations that support them and transmissions sent between the two.

Master Sgt. Desiree Cabrera, 75th ISRS operations superintendent, said the new unit will revolutionize the targeting capabilities of not just the Space Force, but also the entire U.S. military: "Not only are we standing up the sole targeting squadron in the U.S. Space Force, we are changing the way targeting is done across the joint community when it comes to space and electromagnetic warfare." The 75th ISRS will also analyze adversary space capabilities including "counterspace force threats," according to the Space Force's statement. Counterspace forces refer to adversary systems aimed at preventing the U.S. from using its own satellites during a conflict.

The US Is Turning Away From Its Biggest Scientific Partner at a Precarious Time (wsj.com) 131

One of the most productive scientific collaborations of the 21st century is pulling apart, as deteriorating relations between the U.S. and China lead researchers to sever ties. From a report: The decoupling, which began in recent years with investigations into Chinese researchers in the U.S., has accelerated as tensions have risen between the superpowers. Now some U.S. lawmakers are pushing to let a landmark agreement to cooperate on science and technology, signed in 1979 and renewed routinely since, expire this month. China has built itself into a powerful engine of scientific discovery in recent decades, partly with American help, and many in Washington fear that China could gain a security and military advantage unless the U.S. takes decisive steps to cut off cooperation in scientific research.

Many scientists warn, however, that Washington would be severing ties as China is making its greatest contributions to scientific advancements, and cutting it off risks slowing American progress in critical areas such as biotechnology, clean energy and telecommunications. While the U.S. remains the world's pre-eminent science power, fundamental scientific research has grown borderless in the era of globalization, much as business has. More than 40% of America's scientific production -- measured by the number of high-quality papers that U.S.-based scientists produce -- involves cooperation with researchers abroad, according to Clarivate, a London-based data firm that tracks global scientific research. China and the U.S. are each other's No. 1 partner in producing scientific research, with collaborative research between the two consistently among the most-cited papers across fields, according to an analysis of Clarivate's data by Caroline Wagner, a professor of public policy at Ohio State University.

Congressman Bacon Says His Emails Were Hacked in Campaign Linked To China (bloomberg.com) 22

US Representative Don Bacon said he is among those whose emails were hacked in an espionage campaign that Microsoft has attributed to China. From a report:Bacon, a Republican from Nebraska and a strong advocate for US military support to Taiwan, posted on social media that the FBI had notified him that the Chinese Communist Party hacked into his personal and campaign emails over the course of a month, from May 15 to June 16. "The CCP hackers utilized a vulnerability in the Microsoft software, and this was not due to 'user error,'" he wrote on X, the social media platform formerly known as Twitter.

Bacon, a member of the House Armed Services Committee, received an email from Microsoft indicating he may have been hacked and advising him to change his password on June 16, according to Maggie Sayers, Bacon's press secretary. She said that following subsequent notification from the FBI that he had been hacked, Bacon determined emails relating to political strategy, fundraising and personal banking information may have been breached. As a former US Air Force intelligence officer, he is careful to avoid writing sensitive emails relating to China and Taiwan, she said.
