After 10 Years the Navy Throws in the Towel on Ever Completing the USS Boise Overhaul
2026-04-14
[TWZ] The USS Boise has been stuck in limbo for more than a third of its career, and was still years and billions of dollars away from returning to service.

U.S. Navy has abandoned plans to return the Los Angeles class attack submarine USS Boise to active duty. This brings an end to the saga of a still-incomplete major overhaul of the boat, which has lasted more than a decade now. In that time, it has become a poster child for the Navy’s worrisome struggles to tackle huge maintenance backlogs, as well as larger concerns about the availability, or lack thereof, of naval shipyard capacity in the United States.

The Navy announced its decision to inactivate Boise, which was first commissioned into service in 1992, earlier today.

“After a rigorous, data-driven analysis, we’ve made the tough but necessary decision to inactivate the USS Boise,” Navy Adm. Daryl Caudle, Chief of Naval Operations, the service’s top officer, said in a statement. “This strategic move allows us to reallocate America’s highly-skilled workforce to our highest priorities: delivering new Virginia and Columbia class submarines and improving the readiness of the current fleet. We owe it to our Sailors and the nation to make these tough calls to build a more capable and ready Navy.”

“The move is part of the Navy’s broader, data-driven initiative to optimize the fleet’s composition, ensuring that every dollar is invested in capabilities that directly contribute to maintaining a decisive warfighting advantage,” the service also said in a press release. “Funds and personnel associated with the planned overhaul of USS Boise will be redirected to support other Navy priorities, including the timely delivery of America’s submarine capability.”

To date, the Navy has spent approximately $800 million on Boise’s overhaul, which is still only 22 percent complete, the service separately told Semafor. The total estimated cost to complete the overhaul had risen to $3 billion, according to Fox News.

“At some point, you just cut your losses and move on,” Secretary of the Navy John Phelan also told Fox News in an interview ahead of today’s announcement. “The Boise represents 65% of the cost of a new Virginia class submarine, yet it only delivers 20% of the remaining service life.”

The Navy had originally planned for Boise to begin its overhaul in 2013, but the timetable was repeatedly delayed, primarily due to a lack of shipyard availability. The submarine has not been to sea since it returned from its last cruise in January 2015. The boat was deemed unable to conduct normal operations by 2016, and it formally lost its dive certification the following year.

The Navy moved Boise from its home port in Norfolk, Virginia, to Newport News Shipbuilding’s facilities in 2018. Newport News Shipbuilding is a division of Huntington Ingalls Industries (HII).

The submarine returned to Norfolk the following year amid competing funding priorities. It went back to Newport News in 2020, but did not actually enter a dry dock there until 2021, after which limited maintenance work began. The full overhaul was then further set back due to budgetary issues, with a formal contract only signed in 2024.
