General Dynamics (GD) Electric Boat has been selected by the US Navy to provide lead-yard services for Virginia Class nuclear-powered attack submarines.

Under the $91.2m modification contract, Electric Boat will develop, maintain and update design drawings and data for each Virginia Class submarine including technology insertions.

The company will also perform research and development work required to evaluate new technology to be inserted in the newly built Virginia Class ships.

The services are carried out throughout the construction and post-shakedown availability periods of the submarine.

The contract will run through 2014 with a potential value of $881m, if all options are exercised and funded.
