Navy pulls the plug on Boise overhaul, retires aging Los Angeles sub

The Navy decided to inactivate the Los Angeles-class submarine USS Boise after a stalled overhaul that’s only 22% complete; about $800 million has been spent with a projected total cost of up to $3 billion. The decision reallocates funds and skilled labor to new Virginia and Columbia-class submarines, amid long-running maintenance backlogs and limited U.S. shipyard capacity. Boise hasn’t sailed since 2015 and lost dive certification in 2017, illustrating broader challenges facing naval readiness and shipbuilding.
