This bill, titled the "United States-Israel Defense Partnership Act of 2025," seeks to significantly enhance defense cooperation between the United States and Israel, recognizing their shared threats and mutual interests. It establishes a new United States-Israel Counter-Unmanned Systems Program, authorizing $150 million annually for fiscal years 2026 through 2030. This program will focus on developing, testing, evaluating, and deploying advanced technologies to counter unmanned systems, sharing technical expertise, conducting joint research, and integrating these systems for mutual defense.

The legislation also extends and modifies existing defense initiatives. It increases funding for United States-Israel Anti-Tunnel Cooperation from $50 million to $80 million and extends its authorization until December 31, 2028. Similarly, United States-Israel Cooperation to Counter Unmanned Aerial Systems sees its funding increase from $55 million to $75 million, with an extension to December 31, 2028.

Furthermore, the bill authorizes new United States-Israel Emerging Technology Capabilities Cooperation, allocating $50 million annually for fiscal years 2026 through 2030. This initiative will facilitate joint research, development, test, and evaluation in critical areas such as artificial intelligence, cybersecurity, robotics, quantum, and automation, requiring a memorandum of agreement for cost-sharing and intellectual property. The Secretary of Defense is also directed to establish a Defense Innovation Unit office in Israel to foster collaboration against dual-use defense technologies and leverage innovation.

Other key provisions include extending the War Reserves Stockpile Authority until January 1, 2029, and requiring the Secretary of Defense to discuss Israel's potential ascension into the national technology and industrial base. Finally, the bill mandates an assessment of integrated air and missile defense in the United States Central Command (CENTCOM) region, evaluating current strengths, ways to enhance it, and requirements for expanded cooperation among the U.S., Israel, and regional partners, including lessons learned from recent Iranian airstrikes.
