The Pentagon has moved more ground-based air defense systems, including the Terminal High Altitude Area Defense (THAAD) system, to the Middle East as President Trump considers bombing Iran.

… A top State Department official says China detonated a secret underground nuclear blast in 2020.

… Software development for the next-generation Sentinel intercontinental ballistic missile system “remains slower than anticipated,” according to a new U.S. Government Accountability Office snapshot report.

… Adm. Samuel J. Paparo Jr., head of the Pentagon’s Indo-Pacific Command, was in India this week for a roundtable discussion on U.S.-India defense tech cooperation.

… U.S. B-2 bombers and Tomahawk cruise missile attacks on Iranian nuclear facilities last June sparked fear in Beijing that underground Chinese sites are vulnerable, according to a U.S. Air Force think tank report.

… Critics say Mr. Trump is testing free-market orthodoxy with his order that the Pentagon prioritize coal energy over other forms of energy.

… Lockheed Martin says its collaboration with the Japanese information tech company Fujitsu officially “cements” Lockheed’s “commitment to establishing a Japan‑based supply chain” for Aegis System Equipped Vessel SPY-7 radar.

… And the European space-tech company Astrolight is set to demonstrate its compact and energy-efficient ATLAS-1 laser terminals in orbit for the first time.

Hidden Chinese nuclear test in 2020 bolstered ‘nuclear warfighting’

China detonated a secret underground nuclear blast in 2020 that was detected by a seismic station in Kazakhstan and was aimed at improving Beijing’s nuclear warfighting, according to a senior State Department arms control official.

Christopher Yeaw, assistant secretary of state for arms control and nonproliferation, disclosed new details of the Chinese test in remarks this week at the Hudson Institute. Some arms control experts had originally questioned whether the blast even took place, but Mr. Yeaw said the test’s time and place were confirmed by a seismic monitoring station in Makanchi, in southern Kazakhstan.

The underground blast in China registered as a 2.7 magnitude on the seismic scale and its signature was “not consistent with an earthquake,” said Mr. Yeaw, the former chief scientist at the Air Force Global Strike Command. Mr. Trump announced recently that the U.S. would resume nuclear tests on an equal basis with those of China and Russia.

Pentagon official laments some AI companies’ reluctance to fully commit to military’s operations

U.S. Under Secretary of War for Research and Engineering Emil Michael says it’s “disheartening” that some cutting-edge tech companies seem reluctant to fully do business with the military. His comment came amid an escalating feud between the Pentagon and Silicon Valley firm Anthropic over the reported use of the company’s AI tool in recent U.S. Special Forces missions in Venezuela.

Mr. Michael — a Silicon Valley veteran — made the comment at the inaugural Defense Tech Leadership Summit this week in Florida, National Security Correspondent Ben Wolfgang reported. The conference took place as reports circulated that Defense Secretary Pete Hegseth is considering cutting Pentagon ties with Anthropic, creator of the popular Claude AI tool. U.S. forces reportedly used Claude in the operation to capture Venezuelan President Nicolas Maduro in Caracas last month.

The San Francisco-based Anthropic says its usage guidelines prohibit Claude from being used to facilitate violence, develop weapons or conduct surveillance. The unfolding dispute at the highest levels of the federal government and the nation’s increasingly powerful tech sector underscores the thorny, complex questions at play when U.S. forces use a company’s product in a lethal military mission.

U.S. military buildup intensifies as Trump considers strikes on Iran

The White House could order strikes on targets in Iran as early as this weekend, despite Mr. Trump’s insistence that he would rather see a diplomatic solution to ongoing tensions with Tehran. The U.S. has continued to move military assets to the Middle East that would be capable of striking at Iran’s ballistic missile and nuclear infrastructure.

Among the most high-profile assets is the USS Gerald Ford aircraft carrier, which was spotted near Gibraltar on Wednesday. The USS Gerald Ford and its carrier group are expected to join the USS Abraham Lincoln carrier group that arrived in the region last month. The naval buildup, which also includes dozens of refueling tankers and destroyers, would likely be used to defend U.S. bases and personnel in the event of an Iranian response to strikes.

The Pentagon has also reportedly moved additional ground-based air defense systems, including the THAAD and Patriot Missile Defense systems, to the region over the past month. F-35, F-22, and F-16 fighter jets have also been steadily moved from locations across Europe and the U.S. to closer bases in the Middle East, which could facilitate easier, faster military strikes on Iran. Long-range bombers in the U.S. have also been on a higher-than-usual alert status for weeks.

India wants to be AI hub, seeks deeper tech partnership with U.S. military

Indian Prime Minister Narendra Modi told international tech executives at this week’s India AI Impact Summit that the world “must democratize” AI and pitched his country, which has nearly 1 billion internet users, as a key market for advanced technology investments.

The summit is playing out in New Delhi just days after the Trump administration announced a new U.S. trade deal with India, removing a 25% tariff on imports from India in exchange for a commitment from the Modi government to stop buying Russian oil. There are also signs of increased, advanced-tech military coordination between Washington and New Delhi.

Adm. Paparo, head of the Pentagon’s Indo-Pacific Command, and U.S. Under Secretary of Commerce for International Trade William Kimmitt were in India earlier this week for a roundtable discussion on U.S.-India defense cooperation in emerging technology. Mr. Kimmitt is heading a delegation at the India AI Impact Summit that includes representatives from Chevron Engine, Google Deepmind, South Park Commons and Biocon.

Opinion: Harvest deep-sea minerals to combat China

China controls the critical minerals that “underpin America’s economy, including materials used in missiles, microchips, electric vehicles and data centers,” writes Drew Bond, who asserts that “without reliable access to these minerals, manufacturing will stall and our technological edge will disappear.

“The United States imports almost all these minerals from China,” Mr. Bonds, the co-founder and executive chairman of C3 Solutions, writes in an op-ed for The Washington Times. “To break this monopoly and secure America’s future, we must broaden our search for these essential resources to a frontier few Americans have considered: the deep seabeds.

“Polymetallic, mineral-rich nodules on the ocean floor containing nickel, cobalt, copper, manganese and other rare earth elements are a potentially massive, untapped reserve that can reduce our strategic vulnerability,” he writes, adding that “harvesting from the sea floor is the most environmentally sustainable way to obtain the minerals we need.”
