The American military news site Defense One shares a cautionary tale from top U.S. Air Force Major General Daniel Simpson (assistant deputy chief of staff for intelligence, surveillance, and reconnaissance). Simpson describes their experience with an experimental AI-based target recognition program that had seemed to be performing well: Initially, the AI was fed data from a sensor that looked for a single surface-to-surface missile at an oblique angle, Simpson said. Then it was fed data from another sensor that looked for multiple missiles at a near-vertical angle. "What a surprise: the algorithm did not perform well. It actually was accurate maybe about 25 percent of the time," he said.

That's an example of what's sometimes called brittle AI, which "occurs when any algorithm cannot generalize or adapt to conditions outside a narrow set of assumptions," according to a 2020 report by researcher and former Navy aviator Missy Cummings. When the data used to train the algorithm consists of too much of one type of image or sensor data from a unique vantage point, and not enough from other vantages, distances, or conditions, you get brittleness, Cummings said. In settings like driverless-car experiments, researchers will just collect more data for training. But that can be very difficult in military settings where there might be a whole lot of data of one type — say overhead satellite or drone imagery — but very little of any other type because it wasn't useful on the battlefield...

Simpson said the low accuracy rate of the algorithm wasn't the most worrying part of the exercise. While the algorithm was only right 25 percent of the time, he said, "It was confident that it was right 90 percent of the time, so it was confidently wrong. And that's not the algorithm's fault. It's because we fed it the wrong training data."

Graham Allison, a professor of government at Harvard, and Eric Schmidt, former CEO of Google, writing in a column for WSJ: Last year China produced 50% of the world's computers and mobile phones; the U.S. produced only 6%. China produces 70 solar panels for each one produced in the U.S., sells four times the number of electric vehicles, and has nine times as many 5G base stations, with network speeds five times as fast as American equivalents. In the advanced technology likely to have the greatest effect on economics and security in the coming decade -- artificial intelligence -- China is ahead of the U.S. in crucial areas.

A spring 2021 report from the National Security Commission on AI warned that China is poised to overtake the U.S. as the global leader in AI by 2030. U.S.-born students are earning roughly as many doctorates each year in AI-related fields as in 1990, while China is on track to graduate twice as many science, technology engineering and mathematics Ph.D.s as the U.S. by 2025. The Harvard report adds that China now clearly tops the U.S. in practical AI applications, including facial recognition, voice recognition and fintech.

The U.S. still has a dominant position in the semiconductor industry, which it has held for almost half a century. But China may soon catch up in two important arenas: semiconductor fabrication and chip design. China's production of semiconductors has surpassed America's, with its share of global production rising to 15% from less than 1% in 1990, while the U.S. share has fallen from 37% to 12%. In 5G, the Pentagon's Defense Innovation Board reports that China is on track to replicate the economic and military advantages America gained from being the global leader in 4G. China has installed 950,000 base stations to America's 100,000. By the end of last year, 150 million Chinese were using 5G mobile phones with average speeds of 300 megabits a second, while only six million Americans had access to 5G with speeds of 60 megabits a second. America's 5G service providers have put more focus on advertising their capabilities than on building infrastructure. The Chinese Communist Party has made no secret of its ambitions: China intends to become the global leader in the technologies that will shape the decades ahead.

An anonymous reader quotes a report from Ars Technica: The detonation of the first nuclear bombs over Hiroshima and Nagasaki in August 1945 is seared into our collective memory, and the world has been haunted by the prospect of a devastating nuclear apocalypse ever since. Less well-known but equally significant from a nuclear arms race standpoint was the Soviet Union's successful detonation of a hydrogen "superbomb" in the wee hours of October 30, 1961. Dubbed "Tsar Bomba" (loosely translated, "Emperor of Bombs"), it was the size of a small school bus -- it wouldn't even fit inside a bomber and had to be slung below the belly of the plane. The 60,000-pound (27 metric tons) test bomb's explosive yield was 50 million tons (50 megatons) of TNT, although the design had a maximum explosive yield of 100 million tons (100 megatons).

The US had conducted the first successful test of a hydrogen bomb (codename: Ivy Mike) in 1954 and had been pondering the development of even more powerful hydrogen superbombs. But the Soviets' successful test lent greater urgency to the matter. Ultimately, President John F. Kennedy opted for diplomacy, signing the Partial Nuclear Test Ban Treaty on October 7, 1963. But US nuclear policy -- and, hence, world history -- might have ended up looking very different, according to Alex Wellerstein, a historian of science at the Stevens Institute of Technology in New Jersey and author of Restricted Data: The History of Nuclear Secrecy in the United States, released earlier this year. He also maintains the NUKEMAP, an interactive tool that enables users to model the impact of various types of nuclear weapons on the geographical location of their choice.

Wellerstein has analyzed recently declassified documents pertaining to the US response to Tsar Bomba during the Kennedy administration. He described his conclusions in a fascinating article recently published in the Bulletin of the Atomic Scientists, coinciding with the 60th anniversary of the test. [...] According to Wellerstein, the US initially sought to minimize the significance of the Soviets' success, officially dismissing it as a political publicity stunt with little to no technical or strategic importance. But the declassified files revealed that, behind the scenes, US officials took the matter very seriously indeed. Physicist Edward Teller in particular strongly advocated in favor of developing two even more powerful hydrogen bombs, with yields of 1,000 and even 10,000 megatons, respectively. While much of Teller's testimony at a secret meeting on the topic remains classified, Wellerstein found that many scientists who were present expressed shock at his proposal. Concerns about the practical use of such a massive weapon, particularly the widespread nuclear fallout, ultimately scuttled those plans. "I found the new information with regard to the US response to Tsar Bomba really interesting, because it contradicts what they said in public versus what was going on behind the scenes," says Wellerstein. "A lot of the discussions about the Tsar Bomba in American writing essentially parrot then-President Kennedy's line without realizing it: 'Oh, these bombs are worthless. No, they can't do it.' But it's clear that there were people within the Kennedy administration who didn't think it was as simple as that. We can be happy that those people didn't win out."

He added: "There is always this temptation for big bombs. I found a memo by somebody at Sandia, talking about meeting with the military. He said that the military didn't really know what they wanted these big bombs for, but they figured that if the Soviets thought they were a good idea, then the US should have one, too. It's reminiscent of that line from Dr. Strangelove."

Ars Technica sat down with Wellerstein to learn more about the Tsar Bomba test. You can read the full article here.

The US will put SenseTime, the Chinese artificial intelligence company that specialises in facial recognition software, on an investment blacklist on Friday, the same day that it prices its Hong Kong initial public offering. From a report: The action against SenseTime, which Washington says enables human rights abuses against Muslim Uyghurs in Xinjiang, will be part of a package of sanctions against a number of countries to mark Human Rights Day, according to three people familiar with the decision.

The US Treasury will place SenseTime on a list of "Chinese military-industrial complex companies." In June, President Joe Biden signed an executive order that barred Americans from investing in companies on the list, following a Trump administration policy intended to tackle national security threats. The decision to blacklist SenseTime will coincide with the last day of the Democracy Summit that Biden has convened with more than 100 countries. The US president held a virtual meeting last month with Xi Jinping, his Chinese counterpart, in which they discussed ways to ensure that tensions between the countries did not veer into conflict. But Biden has stressed that he will not stop criticising China over human rights abuses.

"The U.S. military has gone on the offensive against ransomware groups," reports CNET, "as U.S. companies increasingly become targets of malware attacks, the nation's top cyber defender acknowledged on Saturday." Up until about nine months ago, reining in ransomware attacks was seen as the responsibility of law enforcement agencies, Gen. Paul M. Nakasone, the head of U.S. Cyber Command and director of the National Security Agency, told the New York Times. But attacks like the ones on Colonial Pipeline and JBS beef plants have been "impacting our critical infrastructure," Nakasone said, leading federal agencies to ramp up the gathering and sharing of intelligence on ransomware groups....

Nakasone didn't describe the action taken or identify the groups targeted, but said one of the goals is to "impose costs" for ransomware groups. "Before, during and since, with a number of elements of our government, we have taken actions and we have imposed costs," Nakasone said. "That's an important piece that we should always be mindful of."

An anonymous reader quotes a report from The Drive: U.S. Space Force's General David Thompson, the service's second in command, said last week that Russia and China are launching "reversible attacks," such as electronic warfare jamming, temporarily blinding optics with lasers, and cyber attacks, on U.S. satellites "every single day." He also disclosed that a small Russian satellite used to conduct an on-orbit anti-satellite weapon test back in 2019 had first gotten so close to an American one that there were concerns an actual attack was imminent.

Thompson, who is Vice Chief of Space Operations, disclosed these details to The Washington Post's Josh Rogin in an interview on the sidelines of the Halifax International Security Forum, which ran from Nov. 19 to 21 in Halifax, Nova Scotia, in Canada. The forum opened just four days after a Russian anti-satellite weapon test involving a ground-launched interceptor, which destroyed a defunct Soviet-era electronic intelligence satellite and created a cloud of debris that presents a risk to the International Space Station (ISS). That test drew widespread condemnation, including from the U.S. government, and prompted renewed discussion about potential future conflicts in space.

"The threats are really growing and expanding every single day. And it's really an evolution of activity that's been happening for a long time," Thompson, told Rogin. "We're really at a point now where there's a whole host of ways that our space systems can be threatened." "Right now, Space Force is dealing with what Thompson calls 'reversible attacks' on U.S. government satellites (meaning attacks that don't permanently damage the satellites) 'every single day,'" according to Rogin. "Both China and Russia are regularly attacking U.S. satellites with non-kinetic means, including lasers, radio frequency jammers, and cyber attacks, he said." [...] Thompson's assertion that these kinds of attacks are occurring with extreme frequency is new. It underscores the rapid development and fielding by Russia and China, among others, of a wide variety of anti-satellite capabilities, something the U.S. military has called increasing attention to in recent years. "The Chinese are actually well ahead [of Russia]," Thompson told Rogin. "They're fielding operational systems at an incredible rate." "Thompson could not confirm or deny whether any American satellites had actually been damaged in a Russian or Chinese attack," the report adds. "[H]e told Rogin that even if such a thing had occurred, that very fact would be classified."

He did, however, provide new details about the incident in 2019 where a small Russian satellite released a projectile in one on-orbit anti-satellite weapon test. According to The Drive, "Russia's satellite had first got in very close to a U.S. 'national security satellite' and that 'the U.S. government didn't know whether it was attacking or not.'"

"It maneuvered close, it maneuvered dangerously, it maneuvered threateningly so that they were coming close enough that there was a concern of collision," Thompson said. "So clearly, the Russians were sending us a message."

schwit1 writes: At least three U.S. federal agencies, including the military, have purchased China-made video surveillance equipment banned from use in the federal government. Purchasing records seen by TechCrunch and video surveillance news site IPVM show the agencies collectively spent thousands of dollars on purchasing video surveillance equipment manufactured by Lorex, a wholly owned subsidiary of Dahua Technology. Dahua is one of several China-based companies banned from selling to the federal government under a 2019 defense spending law over fears that the technology could help the Chinese government conduct espionage.

Today, Vice President Kamala Harris' office released a new framework for US space policy, detailing how the Biden administration plans to approach commercial, civil, and military space activity moving forward. From a report: Called the United States Space Priorities Framework, the document keeps many of the same space priorities from the previous administration but adds a new emphasis on using space to help combat climate change and investing in STEM education. The new framework comes ahead of today's National Space Council meeting, the first one to be held under the Biden administration. Harris, who chairs the National Space Council, will convene the policy advisory group at the United States Institute of Peace in Washington, DC, at 1:30PM ET today.

[...] When it comes to space, the Biden administration is carrying forward many of the priorities set by the Trump administration. Notably, NASA's ambitious Artemis program, which was solidified under Trump, is still a major focus under Biden. And plenty of the topics discussed under Pence's Space Council are included in the new framework released by Harris. A few of the key points include maintaining US leadership in space by sending humans back to the Moon and exploring the Solar System with robotic spacecraft, fostering a competitive, regulatory environment for space companies, and defending against security threats in space while strengthening our space assets. In the biggest break from the previous administration, there looks to be a renewed focus on using space in the fight against climate change. In the new framework, the administration pledges to invest in satellites that can observe Earth from space, helping scientists better understand our changing climate. "Open dissemination of Earth observation data will support both domestic and international efforts to address the climate crisis," the document states. To further drive home this new emphasis on climate research from space, President Biden plans to sign a new Executive Order today that will add five new members to the National Space Council, including the Secretaries of Education, Labor, Agriculture, and the Interior, but also notably the National Climate Advisor.

Iranians couldn't buy gas. Israelis found their intimate dating details posted online. The Iran-Israel shadow war is now hitting ordinary citizens. From a report: Millions of ordinary people in Iran and Israel recently found themselves caught in the crossfire of a cyberwar between their countries. In Tehran, a dentist drove around for hours in search of gasoline, waiting in long lines at four gas stations only to come away empty. In Tel Aviv, a well-known broadcaster panicked as the intimate details of his sex life, and those of hundreds of thousands of others stolen from an L.G.B.T.Q. dating site, were uploaded on social media. For years, Israel and Iran have engaged in a covert war, by land, sea, air and computer, but the targets have usually been military or government related. Now, the cyberwar has widened to target civilians on a large scale. In recent weeks, a cyberattack on Iran's nationwide fuel distribution system paralyzed the country's 4,300 gas stations, which took 12 days to have service fully restored.

That attack was attributed to Israel by two U.S. defense officials, who spoke on the condition of anonymity to discuss confidential intelligence assessments. It was followed days later by cyberattacks in Israel against a major medical facility and a popular L.G.B.T.Q. dating site, attacks Israeli officials have attributed to Iran. The escalation comes as American authorities have warned of Iranian attempts to hack the computer networks of hospitals and other critical infrastructure in the United States. As hopes fade for a diplomatic resurrection of the Iranian nuclear agreement, such attacks are only likely to proliferate. Hacks have been seeping into civilian arenas for months. Iran's national railroad was attacked in July, but that relatively unsophisticated hack may not have been Israeli. And Iran is accused of making a failed attack on Israel's water system last year. The latest attacks are thought to be the first to do widespread harm to large numbers of civilians. Nondefense computer networks are generally less secure than those tied to state security assets.

The US has placed a dozen Chinese groups involved in quantum computing and other advanced technologies on an export blacklist, saying they pose a risk of gaining access to critical American technologies for the People's Liberation Army. From a report: The move, which makes it almost impossible for US companies to sell technologies to the listed companies, targeted a total of 27 entities, including 12 in China and two affiliated firms in Japan and Singapore. In addition to quantum computing, the list included companies in the semiconductor and aerospace industries. Eight of the Chinese groups were specifically targeted to prevent them from accessing sensitive quantum-related technology, the US commerce department said, arguing they could help the PLA improve counter-stealth and counter-submarine applications and facilitate efforts to break US encryption.

The actions mark the latest effort by the Biden administration to make it more difficult for China to secure cutting-edge technologies with military applications. Last month, US intelligence officials warned American companies about Chinese efforts to access technology in areas including quantum computing and artificial intelligence. "This is a sensible move and an important reminder of the scope and scale of China's efforts to achieve technological breakthroughs that erode US national security," said Martijn Rasser, a former CIA official who heads the technology and national security programme at the Center for a New American Security think-tank. In addition to the Chinese groups targeted, Washington put 13 Pakistani firms on the "entity list" for activities related to nuclear and ballistic missile programmes. It added the Moscow Institute of Physics and Technology to a "military end-user" list that makes it more difficult to sell technology with military applications.

Apple co-founder Steve Wozniak's startup Privateer aims to help humanity get the goods on space junk before it's too late. Space.com reports: The Hawaii-based company, whose existence Wozniak and co-founder Alex Fielding announced in September, wants to characterize the ever-expanding space debris population like never before. Privateer will do this by incorporating a variety of data, including crowdsourced information and observations made by its own sizable satellite fleet. "I think we're looking at several hundred satellites," Privateer Chief Scientific Adviser Moriba Jah told Space.com. "We won't launch all several hundred at once; we'll just slowly build it up."

Orbital debris is already tracked by a number of organizations, including the U.S. military and private companies such as LeoLabs. Privateer wants to contribute to these efforts and help ramp them up, eventually creating the "Google Maps of space," as Fielding told TechCrunch last month. To make this happen, Privateer, which is still in "stealth mode" at the moment, plans to build and analyze a huge debris dataset that incorporates information from a variety of sources. "We want to basically be a company that's focused on decision intelligence by aggregating massive quantities of disparate and heterogeneous information, because there's something to be gained in the numbers," said Jah, a space debris expert who's also an associate professor of aerospace engineering and engineering mechanics at the University of Texas at Austin.

Privateer will purchase some of this information, crowdsource some of it and gather still more using its own satellites, Jah said. The first of those satellites is on track to launch this coming February, he added. This information will lead to much more than a census of space junk, if all goes according to plan. The company intends also to characterize debris objects, nailing down their size, shape and spin rate, among other features. "The catalogs of objects out there all treat things like they're spheres," Jah said. "We're going to take it beyond the sphere, to what the thing more realistically looks like and is." Such information will allow satellite operators and others in the space community to better gauge the threat posed by debris objects and improve their predictions about how long pieces of junk will stay aloft, he added. Privateer will make some of its analyses and data freely available for the public good and sell others to customers.

An anonymous reader quotes a report from Ars Technica: The seven astronauts and cosmonauts onboard the International Space Station sheltered inside their respective spacecraft, a Crew Dragon and Soyuz, on Monday morning as the orbiting laboratory passed through an unexpected debris field. This was not a pre-planned collision avoidance maneuver in low Earth orbit, in which the station would use onboard propulsion to move away. Rather, the situation required the astronauts to quickly take shelter. Had there been a collision during the conjunction, the two spacecraft would have been able to detach from the space station and make an emergency return to Earth. Ultimately that was not necessary, and the astronauts reemerged into the space station later Monday. However, as the crew on board the station prepared for their sleep schedule, Mission Control in Houston asked them to keep as many of the hatches onboard the space station closed for the time being, in case of an unexpected collision during subsequent orbits.

It appears likely that the debris field that had alarmed flight controllers on Monday was caused by an anti-satellite test performed by Russia's military early on Monday. [...] It appears that Russia launched a surface-to-space Nudol missile on Monday, between 02:00 and 05:00 UTC, from the Plesetsk Cosmodrome in the northern part of the country. The missile then struck an older satellite, Cosmos 1408. Launched in 1982, the satellite had been slowly losing altitude and was a little more than 450 km above the Earth. This is a large satellite, with a mass of about 2,000 kg. As of Monday afternoon, US Space Command said it was already tracking more than 1,000 pieces of new debris. Although the satellite's altitude is higher than the International Space Station, which is about 400 km above the surface, a kinetic impact would spread a large cloud of debris. Satellite expert Jonathan McDowell believes the Cosmos 1408 satellite is the likely candidate for the space station's ongoing debris event.

During a daily briefing today, US State Department Spokesman Ned Price said the test had created more than 1,500 pieces of trackable debris and hundreds of thousands of pieces of un-trackable debris. "The Russian Federation recklessly conducted a destructive satellite test of a direct-ascent anti-satellite missile against one of its own satellites," Price said. "This test will significantly increase the risk to astronauts and cosmonauts on the International Space Station as well as to other human spaceflight activities. Russia's dangerous and irresponsible behavior jeopardizes the long-term sustainability of outer space."

China has decided to ban access to Flightradar24, a real-time commercial aircraft flight-tracking service that provides equipment to volunteers to collect aviation data. A Chinese national security agency in 2020 discovered that a citizen with the surname Li had signed up to receive the equipment from Flightradar24 and track aircraft. From a report: CCTV reported that Beijing Municipal National Security Bureau found data-sharing poses a security threat to military aircraft. It added that security agencies seized the equipment given to volunteers by Flightradar24. Chinascope recently told you that China's Ministry of State Security declassified an investigation into the theft of Chinese airlines' data by a foreign spy agency. It is unclear if the Flightradar24 case and that are related.

"A drone laden with explosives targeted the residence of Iraqi Prime Minister Mustafa al-Kadhimi in Baghdad early on Sunday," reports Reuters, "in what the Iraqi military called an attempted assassination, but said Kadhimi escaped unhurt." The attack, which security sources said injured several members of Kadhimi's personal protection, came after protests in the Iraqi capital over the result of a general election last month turned violent. The groups leading protests and complaints about the result of the October vote are heavily-armed Iran-backed militias which lost much of their parliamentary power in the election... No group immediately claimed responsibility for the attack on Kadhimi's residence in Baghdad's fortified Green Zone, which houses government buildings and foreign embassies...

Security sources told Reuters that six members of Kadhimi's personal protection force stationed outside his residence had been injured.

The United States Marine Corps and Japan's Maritime Self Defense Force made history last month with an epic flight that relaunched Japan's carrier aviation program. From a report: The flight involving the Japanese aircraft carrier Izumo and American F-35B fighter jets marked the first time Japan has operated an aircraft carrier since 1945. Japan was one of the first pioneering naval aviation powers, but its involvement in World War II saw the destruction of nearly its entire fleet battle force -- particularly the carriers. The flight took place on October 3 in the Pacific Ocean. Two F-35B Joint Strike Fighters operating from Marine Corps Air Station Iwakuni took off from mainland Japan, refueled in midair, and then landed on the ship JS Izumo. The F-35Bs landed vertically on Izumo's flight deck and then performed a rolling takeoff. [...] In December 1941, Japan operated the largest and best-trained carrier force in the world. Japan was heavily reliant on its navy for power projection and took a natural liking to the concept of operating planes from ships. The Imperial Japanese Navy built the world's first purpose-built aircraft carrier, Hosho, in 1922. (Other countries, including the United States, built early carriers by using the hulls of other types of ships.)

On Monday, A group of diplomats from the United Kingdom proposed that the United Nations set up a group to develop new norms of international behavior in space, with the aim of preventing the kinds of misunderstandings that could lead to war. Wired reports: As spacefaring nations advance their military satellite capabilities, including being able to disrupt or damage other satellites, such provocative behavior could escalate already-tense diplomatic situations -- and create more space debris in low earth orbit, a crucial region that's already chock-full of derelict spacecraft. This is the first significant progress in developing space rules in more than four decades. The most important piece of space law, the Outer Space Treaty, was negotiated by the fledgling space powers in 1967.

Monday's vote before the UN's First Committee, which is focused on international security and disarmament, passed overwhelmingly, with representatives of 163 countries voting yea versus eight nays and nine abstentions. Considering the widespread support for the proposal, including backing from the Biden administration, Edmondson expects it to pass in the full UN General Assembly next month. The proposal would create a new working group at the UN that will meet twice a year in Geneva in 2022 and 2023. By the end of that time, the group must reach consensus on new rules and identify areas in need of further investigation. Crafting norms for the kinds of activities that escalate tensions or generate debris will likely be top priority for this group, says Cassandra Steer, an expert on space law and space security at the Australian National University in Canberra.

Three years after an employee revolt forced Google to abandon work on a Pentagon program that used artificial intelligence, the company is aggressively pursuing a major contract to provide its technology to the military. From a report: The company's plan to land the potentially lucrative contract, known as the Joint Warfighting Cloud Capability, could raise a furor among its outspoken work force and test the resolve of management to resist employee demands. In 2018, thousands of Google employees signed a letter protesting the company's involvement in Project Maven, a military program that uses artificial intelligence to interpret video images and could be used to refine the targeting of drone strikes. Google management caved and agreed to not renew the contract once it expired.

The outcry led Google to create guidelines for the ethical use of artificial intelligence, which prohibit the use of its technology for weapons or surveillance, and hastened a shake-up of its cloud computing business. Now, as Google positions cloud computing as a key part of its future, the bid for the new Pentagon contract could test the boundaries of those A.I. principles, which have set it apart from other tech giants that routinely seek military and intelligence work. The military's initiative, which aims to modernize the Pentagon's cloud technology and support the use of artificial intelligence to gain an advantage on the battlefield, is a replacement for a contract with Microsoft that was canceled this summer amid a lengthy legal battle with Amazon. Google did not compete against Microsoft for that contract after the uproar over Project Maven.

The Pentagon's restart of its cloud computing project has given Google a chance to jump back into the bidding, and the company has raced to prepare a proposal to present to Defense officials, according to four people familiar with the matter who were not authorized to speak publicly. In September, Google's cloud unit made it a priority, declaring an emergency "Code Yellow," an internal designation of importance that allowed the company to pull engineers off other assignments and focus them on the military project, two of those people said. On Tuesday, the Google cloud unit's chief executive, Thomas Kurian, met with Charles Q. Brown, Jr., the chief of staff of the Air Force, and other top Pentagon officials to make the case for his company, two people said. Google, in a written statement, said it is "firmly committed to serving our public sector customers" including the Defense Department, and that it "will evaluate any future bid opportunities accordingly."

new nukes "A sophisticated electronic sensor buried in hardened metal shells at the tip of a growing number of America's ballistic missiles reflects a significant achievement in weapons engineering that experts say could help pave the way for reductions in the size of the country's nuclear arsenal," reports the Washington Post, "but also might create new security perils." The wires, sensors, batteries and computing gear now being installed on hundreds of the most powerful U.S. warheads give them an enhanced ability to detonate with what the military considers exquisite timing over some of the world's most challenging targets, substantially increasing the probability that in the event of a major conflict, those targets would be destroyed in a radioactive rain of fire, heat and unearthly explosive pressures.

The new components — which determine and set the best height for a nuclear blast — are now being paired with other engineering enhancements that collectively increase what military planners refer to as the individual nuclear warheads' "hard-target kill capability." This gives them an improved ability to destroy Russian and Chinese nuclear-tipped missiles and command posts in hardened silos or mountain sanctuaries, or to obliterate military command and storage bunkers in North Korea, also considered a potential U.S. nuclear target.

The increased destructiveness of the warheads means that in some cases fewer weapons could be needed to ensure that all the objectives in the nation's nuclear targeting plans are fully met, opening a path to future shrinkage of the overall arsenal, current and former U.S. officials said in a number of interviews, in which some spoke on the condition of anonymity to discuss sensitive technology.

Production of the first of many high-yield nuclear warheads containing the gear, developed over the past decade at a cost of billions of dollars, was completed in July for installation on missiles aboard Navy submarines, the National Nuclear Security Administration announced.
The Post notes that the U.S. has now installed the technology on hundreds of submarine-based warheads, doubling their destructive power (according to estimates by a Georgetown professor).

The acting administrator of America's National Nuclear Security Administration called it "the culmination of over a decade of work."

This week the U.S. Air Force announced that it's chosen Alaska's Eielson Air Force Base as the site for its first "micro" nuclear reactor test program.

The Drive reports: The U.S. military, as a whole, together with the Department of Energy has been increasingly looking into micro-reactor designs as possible ways to meet ever-growing electricity demands, including for units on the battlefield, as well as to help cut costs and improve general operational efficiency by reducing reliance on fossil fuels. The base is situated deep within the interior of Alaska near the city of Fairbanks and is around 110 miles south of the Arctic Circle [and 26 miles from Fairbanks].

It is not clear exactly what the specifications might be for the reactor that is now set to be constructed at Eielson... The Air Force did say that the project in question had been initiated in response to language in the annual defense policy bill, or National Defense Authorization Act for the 2019 Fiscal Year and that the goal is for the micro-reactor to be fully operational by the end of 2027. This would seem to indicate that this reactor is the one that the Office of the Secretary of Defense's Strategic Capabilities Office is leading the development of as part of an effort known as Project Pele. The goal of that project, which started in 2019 and that you can read more about here, is to demonstrate a small reactor capable of producing between one and five megawatts of power...

In March, the Pentagon awarded contracts for prototype Project Pele reactors to X-Energy and BWX Technologies. These deals cover the continued maturation of the respective designs over the next two years, with the expectation being that a winning design will be selected afterward. The hope is that work on an actual microreactor will begin by the end of the 2022 Fiscal Year...

It is worth pointing out that 19,780 acres associated with Eielson are already designated by the U.S. Environmental Protection Agency (EPA) as a so-called "Superfund site," due to existing toxic chemical contamination related to "closed and active unlined landfills, shallow trenches where weathered tank sludge was buried, a drum storage area, and other disposal and spill areas."
Waste from the micro-reactor "will be subject to the same rigorous storage and control requirements of the commercial nuclear industry," explains an Air Force FAQ. (Though more specifically, it says that "Used fuel will be stored on-site using NRC-licensed storage casks pending a decision on the ultimate disposition of commercial spent fuel.") The FAQ also notes the reactor will not be connected to the commercial grid.

The Drive points out that currently the Air Force has just been using a fleet of diesel locomotives that bring the base trainloads of coals.

Big data "has big designs on a big cloud," reports NBC News: A steady drumbeat from some of the most influential executives in the technology industry has emerged in recent months to push the idea that the U.S. government should invest in a "national research cloud" — a hub for U.S. research into artificial intelligence where researchers from academia and smaller tech companies could share data sets and other resources.

It's an idea that has been backed by a government commission led by ex-Google CEO Eric Schmidt and including executives from Amazon, Microsoft and Oracle, which recommended that the Biden administration create a hub for U.S. research into artificial intelligence. The White House has warmed up to the idea, ordering another report on it due next year with an eye toward competing with China on the development of artificial intelligence. "We should be able to stay ahead of China. We estimated that we are one to two years ahead of China, broadly speaking, in this area. I hope that's true," Schmidt said in an interview with NBC News. "Investments that are targeted in research — new algorithms — should be able to keep us ahead," he said.

The stakes could be enormous. Some experts in artificial intelligence believe it has the potential to transform the economy — automating some jobs, while creating new ones — and the potential military applications have spurred investment by the Pentagon.

But this month, the idea began getting fresh pushback. Research groups including New York University's AI Now Institute and Data & Society, a nonprofit technology research group based in New York, say the very tech companies pushing this idea stand to profit from it, because the national hub would likely be housed in the same companies' commercial cloud computing services. They say that's a conflict, and little more than a cash grab by what's effectively the next generation of military contractors. The plan also could entrench the very same tech companies that President Joe Biden's antitrust enforcers are working to rein in, these critics say.
