General Dynamics (GD) Electric Boat has been awarded a contract by the US Navy to support advance planning and preliminary execution efforts for the Los Angeles-class nuclear-powered submarine, USS Miami (SSN 755) fire restoration programme.
Under the $94m cost-plus-fixed-fee delivery contract, the company will manage activities such as assessment and analysis, planning and material procurement, as well as fabrication and initial installation to return USS Miami to the naval fleet with complete mission readiness.
USS Miami suffered fire damage from an accidental blaze in May while it was in a dry dock at the Portsmouth Naval Shipyard in Kittery, Maine, for a 20-month engineered overhaul.
Northrop Grumman and GD-built Los Angeles-class submarines are armed with land-attack and anti-ship version of the Tomahawk missile, Harpoon anti-ship missiles, as well as 533mm torpedo tubes and Mark 117 torpedo fire control systems.
Powered by a 26MW GE PWR S6G nuclear-pressure water reactor, Los Angeles-class submarines have been designed to support anti-submarine warfare, intelligence gathering, strike missions, and mining, as well as search and rescue missions for the US Navy.
Integrated with Sperry Marine BPS 15 A/16 surface search, navigation and fire control radar, the submarines have electronic support measures (ESM), including a BRD-7 direction finding system, the WLR-1H and WLR-8(v)2 interceptors and the WLR-10 radar warning device.
Additional features of the Los Angeles-class boats include a Northrop AN/WLY-1 acoustic interception and countermeasures system.
The contract includes an option for the total award value to rise to $100m if exercised.
Work will be performed at Portsmouth Naval Shipyard in Kittery, US, and is scheduled to be complete by June 2013.
