Raytheon Wins Delivery Order for Repair of F/A-18 APG 65/73 Radar Systems

Raytheon is being awarded a firm-fixed-price delivery order for the repair of the APG 65/73 radar systems in support of the F/A-18 fighter-attack aircraft.

The delivery order, valued at around $56 million, was awarded by the U.S. Naval Supply Systems Command Weapon Systems Support (NAVSUP WSS) located in Philadelphia, Pennsylvania.

Work will be performed in Indianapolis, Indiana, and is expected to be completed by February 2019.

Fiscal 2018 working capital funds (Navy) in the amount of around $27.46 million will be obligated at time of award, and will not expire at the end of the current fiscal year.

AN/APG-65 | AN/APG-73

AN/APG-65 and AN/APG-73 are designations for a family of all-weather multimode airborne radar systems designed by Hughes Aircraft (now Raytheon) for the F/A-18 Hornet, and used on a variety of fighter aircraft types. The APG-79 is an upgraded active electronically scanned array (AESA) version.

These I band (8 to 12 GHz) pulse-Doppler radar systems are designed for both air-to-air and air-to-surface missions. For air-to-air operations they incorporate a variety of search, track and track-while-scan modes to give the pilot a complete look-down/shoot-down capability. Air-to-surface modes include Doppler beam sharpened sector and patch mapping, medium range synthetic aperture radar, fixed and moving ground target track and sea surface search. In the F/A-18, the radar is installed in a slide-out nose rack to facilitate maintenance.

The APG-65 was developed in the late 1970s and has been operational since 1983. Although no longer in production, the APG-65 remains in service in F/A-18 Hornet strike fighters of the U.S. Navy and Marine Corps, and the air forces of Canada, Australia, Kuwait, and Spain. It has also been adapted to upgrade the German and Greek F-4 Phantom aircraft, and the AV-8B Harrier II Plus for the U.S. Marine Corps and the Spanish and Italian Navies.

The APG-73 is a late 1980s “upgrade of the APG-65 that provides higher throughputs, greater memory capacity, improved reliability, and easier maintenance”.

Since 1992 the APG-73 has been operational in U.S. Navy and Marine Corps F/A-18C and D aircraft; early models of the U.S. Navy F/A-18E/F Super Hornet; and in the air forces of Finland, Switzerland, Malaysia, Canada, and Australia. A total of 932 APG-73 systems were delivered, with the final delivery in 2006.
