The first F-15Cs to be upgraded with the AN/APG-63(V)3 Active Electronically Scanned Array (AESA) radar were deployed to Kadena AFB on the Japanese island of Okinawa in late October.
The aircraft are the first of 27 USAF and 18 Air National Guard F-15C/Ds currently under contract to receive the upgrade. Longer term plans call for 54 AESA equipped F-15s to be based at Kadena alone.
The radar upgrade is part of a larger program which will see the youngest F-15C/Ds receive datalinks, GPS navigation and the Joint Helmet Mounted Cueing System (JHMCS).
