AN/APG-63 Legacy RadarThe AN/APG-63 radar is a highly flexible, all-weather multimode radar.

The APG-63 radar combines long range acquisition and attack capabilities with automatic features to provide the instant information and computations needed during air-to-air and air-to-surface combat.

The APG-63 has been operational since 1973. In 1979, it was the first airborne radar to incorporate a software programmable signal processor (PSP). The PSP allows the system to quickly respond to new tactics or accommodate improved modes and weapons through software reprogramming rather than by extensive hardware retrofit.

The APG-63 is no longer in production but remains in service. Almost 1,000 APG-63s had been delivered when production ended in 1986. About 700 are still operational in F-15As, Bs, and early model Cs and Ds operated by the U.S. Air Force and the air forces of Israel, Japan, and Saudi Arabia.


AN/APG-63(V)1 Legacy RadarThe AN/APG-63(V)1 radar is a reliability/maintainability upgrade including state-of-the-art hardware with significant growth opportunities.

As part of a radar retrofit program for the U.S. Air Force, the APG-63(V)1 is being produced to replace outmoded APG-63 radars installed in F-15 C/D aircraft models. Raytheon is supplying radar and spare systems, data requirements, program management, and test equipment to support this retrofit program.


AN/APG-63(V)2 Legacy RadarThe AN/APG-63(V)2 Active Electronically Scanned Array (AESA) radar combines increased pilot situational awareness with improved reliability and maintainability.

The AN/APG-63(V)2 is a major radar upgrade for the U.S. Air Force F-15C aircraft. Retaining controls and displays nearly identical to those of its predecessor, the AN/APG-63(V)1, the new system adds an active electronically scanned array (AESA) radar to proven AN/APG-63(V)1 radar components. Addition of AESA technology substantially increases pilot situational awareness, while enhancing reliability and maintainability.

The AESA radar has an exceptionally agile beam, and provides nearly instantaneous track updates throughout the field of vision. Other benefits of the radar include enhanced multi-target tracking capability and elimination of the need for a hydraulic system.

The AN/APG-63(V)2 is compatible with current F-15C weapon loads, features upgraded identification-friend-or-foe and environmental control systems, and enables pilots to take full advantage of AIM-120 Advanced Medium Range Missile capabilities. It can simultaneously guide multiple missiles to several targets widely spaced in azimuth, elevation, or range.
