Huntington Ingalls Industries' (HII) Newport News Shipbuilding has been contracted by the US Navy to conduct nuclear propulsion and complex modernisation work on the Nimitz-class aircraft carrier, USS Harry S Truman (CVN 75).

The maintenance and modernisation work will be carried out as part of the vessel’s planned incremental availability.

Under the $52m contract, HII will perform planning, material procurement, prefabrication, manpower, support services, design integration, engineering and management support, and technical data.

"We are proud to do the maintenance and modernisation work that is vital to the navy’s ability to carry out its mission."

Newport News in-service aircraft carrier programmes vice-president Chris Miner said: “We are proud to do the maintenance and modernisation work that is vital to the navy’s ability to carry out its mission.

“Our shipbuilders look forward to completing this important work in support of re-delivering a first-rate ship that is ready to continue projecting our navy’s strength at sea.”

Work under the contract will be conducted at Norfolk Naval Shipyard in Portsmouth, Virginia, US, and is slated to be completed by September next year.

Built by Newport News Shipbuilding and based at Naval Station Norfolk, USS Harry S Truman is the eighth Nimitz-class carrier, and was launched in 1996.

The nuclear-powered carrier is designed to conduct a range of missions, such as maritime security operations, expeditionary power projection, forward naval presence, crisis response, sea control, deterrence, counter-terrorism, information operations, and security cooperation.

The USS Harry S Truman embarked air wing has the capacity to provide tactical air power over the sea and inland, as well as providing sea-based air, surface and subsurface defence capabilities.

Last month, Serco was contracted to provide command, control, communications, computers, intelligence, surveillance and reconnaissance (C4ISR) installation services on-board the carrier.
