One of the youngest Los Angeles-class nuclear attack submarines will be inactivated after waiting more than a decade for an overhaul, the Navy announced on Friday.

USS Boise (SSN-764), currently in a drydock at HII Newport News Shipbuilding, Va., has been scheduled for a regular overhaul since Fiscal Year 2016 but has spent years pierside waiting for repairs. While waiting for a slot at Norfolk Naval Shipyard, Va., the 34-year-old submarine lost its dive certification in 2017. After years at the pier, the Navy decided to enlist HII to repair the submarine at Newport News. The boat was towed to Newport News in 2018, back to Naval Station Norfolk and back again to Newport News in 2020. From then, Bosie [sic] waited until the service awarded a $1.2 billion contract to HII for the work in 2024. Combined, the Navy has invested about $1.6 billion [in] Boise, based on Pentagon contract announcements.

Now, after 11 years, the Navy intends to inactivate the attack boat and focus the resources on other new construction and repair projects. Faced with a ship that has been idle for more than a decade, the cost for the repair versus other efforts wasn’t with [sic] it, the sea service said.
