Huntington Ingalls Industries (HII) has been awarded a $1.2-billion contract to overhaul the US Navy’s USS Boise nuclear-powered submarine.
The Los Angeles-class underwater vessel has been sidelined since 2017 due to the service’s ongoing maintenance backlog.
According to the contract announcement, the engineering overhaul will be performed at the company’s Newport News Shipbuilding (NNS) facility in Virginia and is expected to be completed by September 2029.
HII spokesman Todd Corillo told Breaking Defense that the contract will cover the restoration of the submarine’s hull structure, tanks, propulsion systems, electric plant, auxiliary systems, and armaments.
There will also be numerous ship alterations to prepare it for modern-day missions.
“The NNS team looks forward to leveraging our experience in nuclear-powered submarine maintenance to begin this important engineering overhaul,” Corillo said.

Launched in 1991, the USS Boise is a fast-attack submarine designed to form the backbone of the US Navy’s underwater force.
During its active service, it participated in various exercises and combat operations, including Operation Enduring Freedom in 2002 in response to 9/11.
One of its most notable milestones took place in 2003 when it fired Tomahawk missiles during Operation Iraqi Freedom.
The USS Boise lost its dive certification in 2017 due to maintenance delays.
