The House Homeland Security Committee is requesting a briefing from DHS on a breach of the Homeland Security Information Network (HSIN), an unclassified but sensitive platform used by federal, state, local, and private-sector partners. Hackers accessed the network between late May and early June 2026. The network supports World Cup security and America250 events. Senator Mark Warner expressed concern about national security risks, noting the network's role in emergency response during last year's mid-air collision. DHS confirmed the hack and stated it isolated affected systems and launched an investigation.

A Government Accountability Office report reveals that low availability of B-52 bombers, the only platform used for flight testing the AGM-181A Long-Range Standoff (LRSO) nuclear cruise missile, has caused a 4-month delay to initial capability. The B-52 fleet faces heavy operational demands from strikes on Iran and a recent fatal crash, compounding modernization challenges. The Air Force now aims for initial operational capability in November 2030, with 27 remaining test flights needed before operational testing starts in September 2027. The report also highlights software certification risks, cybersecurity testing delays, and a $347 million cost increase due to a production extension.

The Japanese yen continues to weaken, hitting a four-decade low of ¥162.8 per dollar, defying record current account surpluses and Bank of Japan rate hikes. Structural factors such as persistent capital outflows, overseas earnings not repatriated, and yen-based carry trades outweigh cyclical supports. The dollar's strength is cyclical but may fade. The yen's weakness is becoming a source of friction between the US and Japan, with Washington keeping Tokyo on its currency monitoring list and Tokyo's interventions potentially adding pressure on US Treasury yields.

Current methods for testing frontier AI models' cyber capabilities are becoming obsolete as models rapidly surpass benchmarks. Federal agencies are working on a classified benchmarking process by August 1. Industry efforts, including Anthropic's standardized benchmark and Irregular's new cyber benchmark, aim to measure real-world offensive cyber tasks. Experts warn that static tests no longer capture AI's ability to conduct sophisticated attacks or escape sandboxed environments.

The Bipartisan Commission on Biodefense at the Atlantic Council has designated artificial intelligence as its sixteenth technology priority for biodefense, following a June 4, 2026 public meeting on AI and biological threats. The Commission calls for US investment in AI-enabled disease surveillance, diagnostics, medical countermeasure development, microbial forensics, model evaluation, and nucleic acid synthesis screening, citing AI's dual-use potential to both create and counter biological threats.

The U.S. Navy is seeking prototype technologies to protect its ballistic missile submarines (SSBNs) from emerging threats including drones, anti-tank guided missiles (ATGMs), RPGs, and underwater drones, as demonstrated by Ukraine's attack on a Russian sub. The Navy's Strategic Systems Program issued a Sources Sought announcement covering 22 focus areas, including detection and defeat of unmanned systems, protection during port and waterway transits, active protection systems for ground convoys, and countermeasures against AI-enabled threats and drone swarms.

NATO Secretary-General Mark Rutte announced at the alliance's Defence Industry Forum in Ankara that NATO will acquire up to five Northrop Grumman MQ-4C Triton high-altitude, long-endurance UAVs for maritime surveillance. Built by Northrop Grumman, the drones will enhance NATO's intelligence, surveillance and reconnaissance capabilities, particularly in the High North, with European industry involvement in mission support and data systems. The MQ-4C Triton can operate above 50,000 feet for over 24 hours with a range of 7,400 nautical miles.

The U.S. Army has successfully tested an autonomous version of its Volcano mine dispenser system at Camp Grayling, Michigan. The system pairs the M139 Volcano dispenser with a driverless Palletized Load System truck, enabling remote laying of minefields covering up to 32 acres with 960 mines. Soldiers from the 4th Engineering Battalion conducted live-fire and autonomous emplacement demonstrations. Developed jointly with the UK and defense contractor Forterra, the system aims to keep combat engineers out of danger and automatically upload minefield locations to the Army's battlefield map. This test marks a significant step in modernizing legacy equipment with autonomous technology.
