AN/APG-63v2. The world’s first AESA radar system to be operationally deployed in a fighter aircraft, entering service with the F-15Cs at Elmendorf Air Force Base, Alaska in December 2000. At present, 18 operational F-15Cs fly with the APG-63v2 radar, and a 19th F-15C has been equipped with the APG-63v3 for testing purposes. Current plans call for up to 48 more APG-63v3-equipped F-15C/Ds to join them, but some options under discussion could grow that number.
APG-63v3. Combines APG-63v2 AESA software with the hardware advances that went into the F/A-18 E/F
Super Hornet Block II’s AN/APG-79 AESA radar. Whereas the AP-63v2 AESA had a square profile, the APG-63v3 can be recognized by the rounder shape of its array. It uses lighter and more advanced AESA technologies that include a tile array arrangement, and a new processor.
