The US Navy has awarded a contract modification to General Dynamics to provide engineering and technical services for the AN/BYG-1 submarine combat system for SSN21, Virginia and SSN688/688I Class submarines.
The AN/BYG-1 incorporates the tactical control, weapons control and tactical network subsystems on the US Navy and Royal Australian Navy submarines.
The GD-developed weapons control system is based on open-architecture and an open-business model that aids system enhancements.
Work will be carried out in Massachusetts, Virginia and Rhode Island, and is expected to be complete by 2018.
The $11.5m contract modification is the second-year option of a multiyear contract awarded in 2009.
