Nuclear triad modernization, Golden Dome, and NNSA workforce challenges

Purpose

The House Armed Services Subcommittee on Strategic Forces held this hearing to receive testimony on nuclear forces and atomic energy defense activities as the FY2026 budget request was being finalized, though program-level funding details had not yet been released▶ 0:12:32. Witnesses from the NNSA, DoD, Navy, and Air Force discussed nuclear modernization programs (Sentinel, Columbia-class submarines, SLCM-N, B-21, B-52J), the NNSA workforce and non-proliferation cuts, and the debate over President Trump's proposed Golden Dome missile defense system. Begins at▶ 0:11:21

Seth Moulton (D-MA), Ranking Member▶ 0:14:52: Argued nuclear modernization programs are behind schedule and over budget▶ 0:15:43, criticized DOGE-driven personnel losses at NNSA/DoD hurting morale▶ 0:16:11, warned modernization plans assume only one major adversary▶ 0:16:40, and sharply questioned the feasibility and cost of Golden Dome, citing a CBO estimate of $160–542 billion over 20 years▶ 0:18:11.

• Ms. Teressa Robbins, Acting Administrator, NNSA▶ 0:20:09: Reported the first war reserve plutonium pit for the W87-1 was produced at Los Alamos in October▶ 0:21:49, the B61-12 life extension program completed its last production unit in December▶ 0:22:17, and the B61-13 first production unit is expected almost a year ahead of schedule▶ 0:22:40; later confirmed 177 probationary NNSA employees were terminated February 13, with all but 3 later reinstated [0:07:57/1:07:57], and said no national security waiver was granted before the firings▶ 1:08:56.

Andrew Gebara, Deputy Chief of Staff, Strategic Deterrence and Nuclear Integration▶ 0:34:38: Said China is projected to exceed 1,000 nuclear warheads by 2030▶ 0:35:30, explained the Air Force shifted Sentinel to predominantly new silos rather than refurbished ones for cost-effectiveness▶ 0:59:04, and detailed B-52J modernization costing roughly a third of a new bomber▶ 1:14:26.

• Rep. Salud Carbajal (D-CA)▶ 0:56:46: Called for Secretary Hegseth's resignation over handling of classified information▶ 0:57:17, and questioned why it took the Air Force 10 years to determine Sentinel needs new silos▶ 0:58:15.

• Robbins confirmed 177 probationary NNSA employees were fired February 13, 150 reinstated February 14 after a court order, and only 3 of the 177 ultimately declined to return; she said no national security exemption was granted before the terminations▶ 0:07:57.

• Gebara disclosed the Air Force has determined Sentinel will predominantly require new missile silos rather than refurbished 1960s-era ones, calling it a cost-effective restructuring decision made over the past nine months▶ 0:58:15▶ 0:59:04.

• Both Gebara and Wolfe stated they had not personally discussed nuclear deterrence policy changes with the White House, saying such input would come through the Joint Chiefs/combatant commanders and policy channels▶ 0:48:21.
