Huntington Ingalls Industries' (HII) Newport News Shipbuilding has secured a contract to carry out planning in support of maintenance and modernisation efforts on the US Navy's Los Angeles-class submarine, USS Columbus (SSN 762).
Work under this $57.8m contract includes maintenance and restoration of the ship's hull structure, tanks, propulsion systems, electric plant, auxiliary systems, armament and furnishings, as well as numerous ship alterations.
The total value of the contract is expected to be $288m if all options are exercised.
Newport News Shipbuilding submarines and fleet support vice-president Jim Hughes said: "Modernisation and maintenance of our nation's submarines is vital to the readiness of our navy partner.
"We look forward to doing our part to provide these services with the highest quality, on budget and on schedule."
Work under this project is scheduled to be completed in May 2019.
The USS Columbus is equipped for anti-submarine warfare, intelligence gathering, show-of-force missions, insertion of special forces, strike missions, mining and search and rescue.
The vessel features a vertical launch system for Tomahawk cruise missiles and an enhanced hull design for under-ice operations.
The Los Angeles-class submarines carry the Harpoon anti-ship missile, which uses active radar homing to deliver a 225kg warhead.
In June, Newport News Shipbuilding division received a $23.8m contract from the US Navy for nuclear propulsion and complex modernisation work on the aircraft carrier, USS George H W Bush (CVN 77).
