Huntington Ingalls Industries' (HII) Newport News Shipbuilding division has been awarded a $106m contract to deliver submarine engineering and industrial works for the US Navy.
The total value of the contract will be $564m if all the options are exercised. The various US navy submarine classes include the Los Angeles, Seawolf, Virginia, and Ohio vessels.
Under the cost-plus-fixed-fee contract, the company will also offer its engineering and industrial expertise for the US navy special mission submersibles, submarine support facilities, and related programmes.
Newport News engineering and design vice-president Jennifer Boykin said: "Receiving this contract allows Newport News Shipbuilding to continue decades of delivering the best engineering, design, and logistics support for US Navy submarines.
"We look forward to providing continued support to the operational readiness of our nation's submarine force."
Services will also include engineering, design, configuration management, and integrated logistic support, as well as database management, research and development, modernisation, and industrial support.
The US Naval Sea Systems Command, Washington, District of Columbia, will serve as the contracting activity.
Work under the contract will begin immediately and will be carried out in Newport News, Virginia, US, and is expected to continue through September 2019.
Newport News is one of two US shipyards with the capability for nuclear-powered submarines. It has also repaired hundreds of ships for the US Government, which range from paint repair to hull and machinery renovation.
