Senate Seapower Hearing: Navy Officials Warn of Delays, Workforce and Supply‑Chain Strains in Nuclear Shipbuilding

The Senate Armed Services Subcommittee on Seapower heard testimony Tuesday that the United States’ nuclear shipbuilding effort is facing sustained delays and capacity shortages that could affect delivery of Columbia‑class ballistic missile submarines, Virginia‑class attack submarines and Ford‑class aircraft carriers.

Rear Admiral Todd Weeks, program executive officer for strategic submarines, told the committee that “the Columbia class is the Navy's number 1 acquisition priority and a critical once‑in‑a‑generation recapitalization effort” and that the lead Columbia is projected to be “12 to 18 months late to contract.” He said the second Columbia, the future Wisconsin, is on schedule and that early procurement and construction activities are underway for the next five boats.

The hearing drew sustained attention because those programs underpin the Navy’s force posture and allied commitments. As Rear Admiral Jonathan Rucker, program executive officer for attack submarines, noted, the Navy’s requirement is a force of 66 attack submarines and officials said the industrial base must reach a sustainable annual production cadence — summarized in Navy briefings as “1 Columbia plus 2 Virginia” and later ramping for allied needs — to meet that requirement.

Navy and program witnesses laid out the principal causes of delay and cost pressure: workforce shortages, supplier and material delivery problems, shipbuilder facility constraints and first‑of‑class learning curves. Matt Sherman, program manager for the Navy’s Maritime Industrial Base Office, said the industrial base “must…
