Raytheon was awarded a contract from the U.S. Navy to develop the Advanced Airborne Sensor (AAS), the follow-on to the Littoral Surveillance Radar System (LSRS). Raytheon said the AAS program will equip the P-8A Poseidon. LSRS is currently operational on Navy P-3C Orions; the AAS will provide airborne radar surveillance with next-generation line-of-site capability. As the sensor prime contractor, Raytheon will oversee the mission systems integration, consisting of the development, production and installation of the AAS on the Poseidon. Raytheon will work with its associate prime contractor, Boeing, for engineering, aircraft modifications, integration and flight test, the company said.
