TEWKSBURY, Mass., Aug. 21, 2007 /PRNewswire/ -- The U.S. Navy has recommended Raytheon Company's (NYSE: RTN) advanced submarine combat control system, AN/BYG-1, for fleet introduction on the SSGN Ohio Class and SSN-21 Seawolf Class attack submarines after favorable tests and evaluations. The recent Follow-on Operational Test & Evaluation reports highlighted several performance enhancements and confirmed the operational effectiveness and suitability of the AN/BYG-1(V)6 and (V)7 for the SSN-21 and SSGN platforms.

AN/BYG-1 exploits the power of sonar, electronic support measures, radar, navigation, periscopes, communication, command and weapons to provide a fully integrated submarine combat system.
