Desiring a replacement for its fighter-model F-104s until the Panavia Tornado could become availible, the West Germans considered a simplified F-4E export version, with a single-seat and no Sparrow capability. This "lightweight" Phantom was passed over in favor of the F-4F, based on the F-4E and retaining the two seats but lacking a fuel cell, refueling receptacle, and AIM-7 compatibility. A total of 175 aircraft were bought, with deliveries taking place between 1973-1978.
The original F-4F configuration with no BVR missiles or inflight refueling capability considerably lessened the potential of these otherwise formidable aircraft, and in due course reufeling receptacles and provision for AIM-7 carriage were added.
The F-4F ICE (Improved Combat Efficiency) program was instituted in 1983 to give the F-4F force a new lease on life pending the arrival of a new all-European fighter - this would be a long wait, as the resulting Eurofighter Typhoon would not enter Luftwaffe service for another two decades. ICE replaced the F-4F's radar with an APG-65GY set, derived from that of the F/A-18 Hornet. This permitted a look-down/shoot-down capability, as well as compatibility with the AIM-120 AMRAAM. A total of 110 aircraft were put through the full ICE process, while 37 other aircraft tasked with the strike role did not receive the new radar.
