A group of Democratic lawmakers have demanded answers from the White House following reporting that a top presidential aide intervened to secure a $620 million Pentagon loan to Vulcan Elements, a North Carolina rare-earth magnet startup with a financial link to Donald Trump Jr. ProPublica reported that Trump Jr.’s venture firm, 1789 Capital, took an undisclosed stake in Vulcan about three months before the loan was approved and that Peter Navarro, the president’s senior counselor for trade and manufacturing, initiated the request. Legislators including Sens. Elizabeth Warren, Richard Blumenthal and Mazie Hirono and Reps. Jason Crow and Mike Levin sent a letter to White House Chief of Staff Susie Wiles seeking details about Navarro’s involvement, whether the president was aware, and whether other Trump-linked firms received similar interventions. Defense Department records and interviews cited by ProPublica say Vulcan’s application was the only Pentagon funding request initiated by a top White House aide and that officials were pushed to move unusually quickly. The loan was part of U.S. efforts to onshore critical mineral supply chains and came alongside a reported $50 million Commerce Department award. Navarro has called the reporting "fake news"; the Pentagon said outside affiliations do not affect funding decisions.

Australia will acquire three second-hand US Navy Virginia-class nuclear attack submarines under a revised AUKUS agreement announced in early June 2026, replacing an earlier plan for two used boats and one newly built vessel. Australian officials say talks with the United States on the change began about 18 months ago and that the first transfer is expected around 2032, with boats roughly six years into service and with an overall hull life of about 30–33 years. Canberra and Washington argue the shift simplifies operations, training and logistics and offers modest cost savings while the bespoke SSN-AUKUS model is developed for the 2040s. Critics and some Labor figures warn of maintenance backlogs, shorter remaining service lives, unforeseen refit costs and deeper strategic entanglement with US naval operations. US congressional authorisations and US industrial production constraints — currently below levels needed to sustain both US fleet demands and AUKUS transfers — remain complicating factors for the timetable and legal transfer mechanisms.

Britain has begun using SpaceX’s militarised Starshield satellite network for operational military traffic, sources told Reuters on June 2, making the UK one of the first countries beyond the United States to adopt the government-focused variant of Starlink. The Ministry of Defence said it would not comment on Starshield but emphasised that personnel still use Starlink for non-operational purposes and that it “is not used for military operations.” Sources said the MOD started transitioning operational traffic to Starshield around the start of 2026, using third-party distributors rather than contracting directly with SpaceX. It is unclear how widespread the deployment is or how much the UK pays; one industry source said Starshield costs only slightly more than Starlink. The move follows growing military use of Starlink since 2022, including in Ukraine, and comes after reports SpaceX raised Pentagon prices for Starlink services used to guide drones. SpaceX did not comment; the company is set to pursue a high-profile public listing in mid-June 2026. Other NATO members have also been reported to use Starlink to varying degrees for communications and non-weapons purposes.

U.S. officials have discussed whether to allow additional NATO allies to host U.S. nuclear-capable forces, the Financial Times reported on June 2-3, 2026. Citing people briefed on the talks, the report said Washington signalled openness to expanding NATO’s nuclear-sharing arrangements beyond the current group of European hosts, with Poland and some Baltic states among those expressing interest. Conversations are taking place within NATO channels but any agreement is not imminent, and U.S., Pentagon and NATO spokespeople did not immediately comment. The talks come amid Russia’s war in Ukraine, concerns on NATO’s eastern flank, planned U.S. reductions in conventional forces in Europe, and public U.S. pressure on allies to boost defence spending. Experts note that forward-deploying U.S. dual-capable aircraft and weapons would require years of planning, construction of specialised vaulting and security measures, and political approvals in host countries. The Financial Times is the primary source for the report; subsequent coverage has elaborated on operational and diplomatic implications.

Huntington Beach-based defense startup Mach Industries said it raised $300 million in a Series C round that values the company at $1.8 billion. The round was led by Infinite Capital and Ribbit Capital and attracted participation from existing backers including Sequoia Capital, Khosla Ventures and Bedrock Capital. Founded in 2023 by Ethan Thornton, the company builds advanced unmanned systems — including Viper, Glide, Stratos, Dart and Pike — and supplies U.S. military customers such as the Army, Air Force and SOCOM as well as allied governments. Mach said the funds will expand its Forge flexible manufacturing network, advance propulsion and energetics work (following its acquisition of Exquadrum, now Mach Energetics), accelerate product development and scale production and headcount. Company executives have signalled plans to ramp production and enlarge its workforce to support transition from rapid development to scaled manufacture of strike and surveillance systems.
