Raytheon won a $51.8 million contract modification with the U.S. Navy for the full-rate-production of 53 AN/ALR-67(V)3 Radar Warning Receivers for the U.S. Navy; Canadian Air Force; and the Finnish Air Force, including spare weapon replaceable assemblies for the U.S. Navy. The AN/ALR-67(V)3 RWR is a radar warning receiver that provides visual and aural alerts to F/A-18E/F aircrew upon detection of ground-based, ship-based or airborne radar emitters. It is designed to enhance pilot situational awareness by providing accurate identification, lethality and azimuth displays of hostile and friendly emitters. Work will be performed in Forest, Miss. (46 percent); Goleta, Calif. (14 percent); Lansdale, Pa. (10 percent); Brisbane, Australia (9 percent); Chatsworth, Calif. (7 percent); El Segundo, Calif. (7 percent); McKinney, Texas (4 percent); and Portland, Ore. (3 percent), and is expected to be completed in March 2011.
