Navy's Shipyard Overhaul: $21B Plan Now Looks Like $200B

A GAO report says the Navy's shipyard modernization program could take 50 years and cost nearly ten times its original estimate.

What the Navy once priced at $21 billion and 20 years may ultimately run to $200 billion across 50 years — a reckoning documented in a new Government Accountability Office report released today. [1]

The Shipyard Infrastructure Optimization Program, launched in 2018, targets drydocks and equipment at four public shipyards in Virginia, Maine, Washington, and Hawaii — the facilities responsible for maintaining the Navy's nuclear-powered carriers and submarines. [1]

Dry-dock projects at Portsmouth and Pearl Harbor alone grew by more than $2.5 billion since Congress was first asked to fund them. [1]

The GAO recommended that Congress require the Navy to share an annual and standardized report to lawmakers detailing the program's cost and status. [1]

Cost overruns of this magnitude are not merely budget line items — they are architectural decisions about what a navy can actually sustain, and which ships make it back to sea on time.

Navy officials have projected a 10 percent improvement in aircraft carrier maintenance and a 15 percent improvement in submarine maintenance once the program is complete — with submarine maintenance windows shrinking by roughly three months from their current 25-to-36-month span. [1]

Meanwhile, President Donald Trump is pushing for a fifth public shipyard. Whether Congress can fund even the existing four remains an open question. [1]
