Huntington Ingalls Industries' (HII) Newport News Shipbuilding has secured a contract to carry out planning work in support of maintenance and modernisation work on the US Navy's Los Angeles-class nuclear-powered submarine, USS Helena (SSN 725).
Under the $17.7m contract, HII will conduct design studies, risk assessments, engineering, material procurement and pre-fabrication, logistics, ship checks, and planning documentation.
Work under the contract will begin with immediate effect and is slated to be completed in October 2017.
Newport News Shipbuilding submarines and fleet support vice-president Matt Needy said: “Our shipbuilders are committed to providing quality engineering and planning services to our Navy customer.
“We recognise the importance of returning these submarines to the fleet with increased capability, and we are committed to do so on budget and on schedule.”
Commissioned in 1987, USS Helena has a length of 362ft and a displacement capacity of 5,808t.
The Los Angeles-class submarines are equipped with a vertical launch system for Tomahawk cruise missiles and an enhanced hull design for under-ice operations.
The submarines carry the Harpoon anti-ship missile, which uses active radar homing to deliver a 225kg warhead.
Recently, HII was awarded a $14m base contract to conduct overhaul work on the US Navy’s Arleigh Burke-class (DDG 51) destroyer, USS Ramage (DDG 61).
