<hi style=afpcap>The basic F-4 airframe readily lent itself being modified for the reconnaissance role with an extended forward fuselage designed to house several photographic sensors. Designated the RF-4C, the version was ordered from several years commencing in 1963 to replace the RF-101 Voodoo. The recce Phantom was fitted with a variety of systems including high and low altitude panoramic cameras, as well as an oblique camera. In addition a sideways looking radar and an infra red line scanner were installed in the fuselage. Deliveries of the RF-4C began in 1965 with slightly over 500 being produced during an eight year period. Tactical Air Command was the primary user, with additional aircraft operated by USAFE and PACAF. The latter organisation relied heavily on the RF-4C for pre and post strike reconnaissance imagery during the Vietnam War with thousands of sorties being flown by these unarmed aircraft. The RF-4C was latterly transferred to the Air National Guard with one squadron still operational with the RF-4C during 1995.</hi>
