The F-15K variant has several features not typically found on F-15Es, such as an AAS-42 Infra-red search and track, a customized Tactical Electronics Warfare Suite to reduce weight and increase jamming effectiveness, cockpit compatibility with night vision devices, ARC-232 U/VHF radio with Fighter Data Link system, and advanced APG-63(V)1 mechanical-scanned array radar. The APG-63(V)1 radar has common digital processing equipment with the APG-63(V)3 AESA radar, and thus is upgradable to an AESA radar via antenna replacement. The F-15K is equipped with the Joint Helmet Mounted Cueing System and weapons such as AGM-84K SLAM-ER, AGM-84H Harpoon Block II, KEPD 350. This patch was created for the ROK unit that participated in the 2012 RED FLAG Exercise at Nellis AFB, NV. It says “F-15K SLAM EAGLE” (top), was found in a Korean embroidery shop, has the “theater-made” feel with the ‘cut’ edge, and does not have velcro attached.
