ARLINGTON, Va., March 4 -- The US Navy’s Naval Sea Systems Command has awarded General Dynamics Advanced Information Systems (AIS), a business unit of General Dynamics, a $10 million contract for fabrication, integration, test and delivery of seven photonics mast workstations (PMWs) for installation on Virginia-class submarines. The PMWs are used to control and display imaging sensor data from the AN/BVS-1 photonics mast system. The contract includes engineering services ifor the development, field maintenance and modification of the photonics mast workstations for integration into the photonics mast system. The photonics mast is an electronic imaging sensor set contained on a mast that does not penetrate the submarine hull, as do conventional periscopes. Work will be performed in Fairfax, Va., and is expected to be completed by August 2011. For more information, visit: www.gd-ais.com
