General Dynamics Electric Boat Wins Contract Modification for USS Indiana (SSN 789) Post-Delivery Work Period

General Dynamics Electric Boat (GDEB) is awarded a contract modification for planning and execution of post-delivery work period of the U.S. Navy Virginia-class fast attack submarine, USS Indiana (SSN 789).

The cost-plus-fixed-fee modification, worth around $14 million, was awarded by the Supervisor of Shipbuilding Conversion and Repair (SUPSHIP) located in Groton, Connecticut. Fiscal 2018 shipbuilding and conversion (Navy) funding in the amount of around $8.6 million will be obligated at time of award.

The work includes long-lead-time material procurement, in preparation to accomplish the maintenance, repair, alterations, testing and other work on USS Indiana. The work will be performed in Groton, Connecticut, and is expected to be completed by April 2019.

USS Indiana (SSN 789) was commissioned into the Navy fleet during a ceremony at the Navy Port at Cape Canaveral Air Force Station in Port Canaveral, Florida on Sept. 29 this year.

Indiana is the 16th Virginia-class fast attack submarine and the sixth Virginia-class Block III submarine.  She was the third U.S. Navy ship to be christened with the name Indiana.

As a Block III submarine, Indiana features a redesigned bow, which replaces 12 individual Vertical Launch System (VLS) tubes with two large-diameter Virginia Payload Tubes each capable of launching six Tomahawk land attack cruise missiles (LACM), among other design changes that reduced the submarines’ acquisition cost while maintaining their outstanding warfighting capabilities.

Indiana was constructed by Huntington Ingalls Industries (HII) in partnership with the Electric Boat division of General Dynamics (GDEB) in Newport News, Virginia, with the initial contract awarded on 22 December 2008. Her keel was laid on 16 May 2015 and she was launched on 9 June 2017. She was christened on 29 April 2017 and sponsored by Diane Donald, wife of Admiral Kirkland H. Donald, USN (ret).

Virginia-class submarines are built to operate in the world’s littoral and deep waters while conducting anti-submarine warfare; anti-surface ship warfare; strike warfare; special operation forces support; intelligence, surveillance, and reconnaissance; irregular warfare; and mine warfare missions.

Their inherent stealth, endurance, mobility, and firepower directly enable them to support five of the six maritime strategy core capabilities—sea control, power projection, forward presence, maritime security, and deterrence.
