Raytheon received a $16.6 million order for performance based logistics (PBL) support of its ALR-67(V)3 radar warning receiver system, which protects crews of U.S. Navy F/A-18E/F carrier-based tactical aircraft. The contract encompasses Mission Support of fielded ALR-67(V)3 systems, including repairs, spares, reliability and maintainability system improvements, obsolescence management, and field installation support. The company said the AN/ALR-67(V)3 system provides techniques to detect and identify threat radar emitters, thereby enhancing the survivability of aircraft equipped with the system. More than 400 radar warning receivers plus spares have now been ordered under the overall production program, including systems for F/A-18 aircraft of the Royal Australian Air Force. Work on the radar warning receiver system is being done by the company's Electronic Warfare organization in Goleta, Calif., with support of facilities in El Segundo, Calif., Forest, Miss., and McKinney, Texas.
