Raytheon received two U.S. Navy contracts worth $89 million to provide the AN/AQS-22 Airborne Low Frequency Sonar system, the primary undersea warfare sensor for the U.S. Navy’s MH-60R multi-mission helicopter. The airborne AN/AQS-22 capabilities include submarine detection, tracking, localization, classification, acoustic intercept, underwater communication and environmental data collection. Work will be performed at Raytheon’s Seapower Capability Center, Portsmouth, R.I., and by AN/AQS-22 partners DRS Sonar Systems, Gaithersburg, Md., and Thales Underwater Systems, in Brest, France. Work is expected to be completed by 2010.
