GAO urges annual reporting on Navy's $200 billion shipyard overhaul

The Government Accountability Office's latest report recommends that Congress require the Department of the Navy to submit annual, consolidated status updates on the Shipyard Infrastructure Optimization Program (SIOP). The reports would detail total expenditures to date, original and current schedule and cost estimates, performance metrics and risk analyses for the program's projected 50-year, $200 billion lifespan.

GAO's analysis shows SIOP will surpass $200 billion and extend beyond 50 years, with planning and cost estimates already exceeding original projections. Environmental challenges, such as those at Puget Sound Naval Shipyard, have added projects and increased work scope, driving up costs.

While the Navy's oversight framework adopts tools used for major defense acquisition programs, GAO found it lacks explicit steps to periodically reevaluate program requirements, objectives and resources after the Gate 5/Milestone B-C approval and during implementation. Without such reviews, the program's alignment with future fleet warfighting needs may drift.

The report also notes that the Navy does not provide Congress with a consolidated, standardized view of SIOP's full program costs and risks, unlike the annual status reports required for major defense acquisitions. This information gap could lead to congressional decisions based on incomplete data, risking billions of taxpayer dollars.

The Navy has agreed to GAO's three recommendations: embed periodic Gate 6 sufficiency reviews of mission readiness, affordability and sustainability; conduct annual Gate 6 reviews of SIOP's validated CDD requirements; and document the roles and responsibilities of key SIOP project-management organizations, including PMO 555 and NAVFAC, in the SIOP Concept of Operations.
