S-3163 : Still Just a Bill


S. 3163, introduced in the Senate on November 7, 2025, by Ms. Slotkin and Mr. Sheehy, aims to enhance defense collaboration between the United States and Taiwan. The bill mandates the Secretary of Defense, in coordination with the Secretary of State, to seek engagement with Taiwanese officials to establish a joint program focused on:

  • Fielding uncrewed systems (drones) and counter-uncrewed systems capabilities.
  • Co-developing and co-producing these capabilities for both U.S. and Taiwanese armed forces.
This program must align with the Taiwan Relations Act.

The Secretary of Defense can utilize existing statutory authorities to execute this joint program. Furthermore, the bill requires annual reports to Congress, starting 180 days after enactment and continuing through 2029, detailing:

  • Engagements with Taiwan.
  • Activities related to fielding uncrewed and counter-uncrewed systems.
  • Progress on defense trade agreements (e.g., reciprocal procurement, supply security).
  • Identified resources or authorities needed for fielding these systems.
  • Any other relevant information.

The reports will be submitted to the Armed Services, Appropriations, and Foreign Relations/Affairs Committees of both the Senate and the House of Representatives.
