A bill to require the Secretary of Defense to seek to engage appropriate officials of Taiwan in a joint program with Taiwan to enable the fielding of uncrewed systems and counter-uncrewed systems capabilities.

Introduced on November 7, 2025, S.3163 requires the Secretary of Defense, by March 1, 2026, to engage Taiwan in a joint program for co-development and co-production of uncrewed systems and counter-uncrewed systems capabilities. The bill was read twice and referred to the Senate Armed Services Committee, where it remains in early stages. Critically, this bill does not authorize or appropriate specific funding amounts—it is a mandate bill that establishes a program structure. Actual funding would require separate appropriation or inclusion in the FY2027 or FY2028 NDAA. The money trail runs through the DoD's acquisition authorities under Title 10. The mandate requires the Secretary to use existing statutory authorities, meaning funding will likely be requested as a new start program element within future budget submissions. The related bills list includes S.2296 and S.1071 (both NDAA FY2026), confirming this bill is part of the broader NDAA policy coalition. The Presidential Determination of April 20, 2026 on Defense Production Act mobilization provides executive branch momentum for accelerating defense industrial base capacity, which indirectly supports this bill's co-production goals. Structural winners are pure-play uncrewed systems companies: Kratos ($KTOS) for tactical jet-powered drones (XQ-58A, BQM-177) and AeroVironment ($AVAV) for loitering munitions (Switchblade) and tactical ISR drones (Puma, Shrike). Both are 80%+ confidence picks because their primary business is directly named in the bill's scope. Diversified primes RTX ($RTX, Coyote C-UAS/KuRFS radar) and NOC ($NOC, IBCS C-UAS command and control) benefit from the counter-UAS mandate but at lower confidence (70-75%) due to diversification. Real market data shows the entire defense sector in a severe 30-day trough. All tracked tickers except GD have double-digit 30-day declines: LMT -15.64%, NOC -15.61%, KTOS -12.07%, RTX -9.43%. AVAV is the only exception at +1.23% 30-day. The 7-day snapback in GD (+9.2%) and RTX (+0.25%) suggests the sector may be grounding from oversold levels. KTOS at $62 represents the deepest technical discount (53.7% below 52-week high), offering the highest beta to this catalyst if it gains legislative traction. Timeline: The bill has two actions since November 2025 (introduction and referral to committee), indicating stalled velocity. Passage requires SASC markup and floor vote in the Senate, then House companion and conference. The most likely vehicle is inclusion as a provision in the FY2027 NDAA (markup mid-2026, passage late 2026). The actual program structure would begin after March 1, 2026 deadline, with the first report to Congress due September 2026. Revenue impact to selected companies would begin in FY2027-FY2028.
