General Dynamics‘ (GD) Electric Boat has been awarded a contract modification by the US Navy to provide long lead-time material for three Virginia-class submarines, including the SSN-793, SSN-794 and SSN-795.
Under the $121.8m contract modification, General Dynamics will provide steam and electrical-plant components, a main propulsion unit and ship-service turbine generator sets for the second fiscal 2014 Virginia-class submarine (SSN 793) and the two fiscal 2015 Virginia-class submarines (SSN 794 and SSN 795).

By GlobalDataEquipped with 12 vertical missile launch tubes and four 533mm torpedo tubes, the submarines are capable of firing up to 26 mk48 ADCAP mod 6 heavyweight torpedoes and sub harpoon anti-ship missiles from the 21in torpedo tubes.
Additional features of the boats include Northrop Grumman-built AN/WLY-1 acoustic countermeasures system, mast-mounted AN/BLQ-10 electronic support measures (ESM) and Sperry Marine AN/BPS-16(V)4 navigation radar.
The Electric Boat, in partnership with the US Navy, aims to reduce ship costs while retaining capabilities through overall efficiency improvements, decreased ship-construction labours costs and shortened ship-construction cycle times.
Scheduled for completion by September 2014, work under the contract will be carried out in California, Pennsylvania, New Jersey, Connecticut, Virginia, Massachusetts, and other efforts will be performed at various sites throughout the US.
The US Naval Sea Systems Command will serve as the contracting activity.
