AN/APG-63(V)1
The APG-63(V)1 radar is a 1990s reliability/maintainability hardware redesign which also provided significant mode growth opportunities. It was designed to replace outmoded APG-63 radars installed in F-15C/D aircraft models, providing improved performance and a tenfold increase in reliability. The new radar is able to track 14 targets simultaneously while being able to simultaneously attack 6 of those. Raytheon delivered 180 APG-63(V)1 radar systems to the U.S. Air Force (4 of which have since been lost to crashes), and is on contract to deliver an additional 40 radars to the Republic of Korea Air Force for the F-15K Slam Eagle.
