The 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.
