The US Navy has awarded a $152.8m contract to General Dynamics Advanced Information Systems (GDAIS) to provide submarine fire control and attack weapon control systems.

Under the two-year contract GD will support services for the advanced submarine systems, US/UK SSBN fire control system (FCS) and the SSGN attack weapon control system (AWCS).

The contract is part of the US/UK sea-based strategic deterrent (SBSD) strategic weapons system (SWS) fire control subsystem for the concept development, prototyping and initial design efforts for a common missile compartment (CMC) for the SSBN and SSGN Ohio Class replacement.

Under the contract, the company will provide support services and strategic systems programme alterations including engineering support, performance evaluation, logistics, fleet documentation, reliability maintenance, engineering services and training to sustain the FCS and AWCS.

In addition, GDAIS will provide technical and engineering support to the CMC concept-development efforts for SWS life-cycle cost-control evaluations related to the fire-control subsystem.

The work, which will be carried out in Massachusetts, is expected to be complete by December 2012.
