Kit #AA2018. 1/72 scale. Highly-detailed resin kit with decals. In 1955, the USAF launched the LRIX (Long-Range Interceptor Experiment) program with the goal of producing a fighter capable of March 3 performance, and that could destroy attacking Soviet bombers over the Poles before they could get near U.S. territory. It was also designed to be the escort fighter for the North American XB-70 Valkyrie bomber. As the XB-70 was developed and built by North American Aviation, the company was also issued a contract for two prototypes, of the now-designated F-108A Rapier. The F-108A was designed as a large delta-winged aircraft, powered by a pair of after-burning turbojets. A mockup was inspected in January 1959 with planned first flight in 1961. However, by mid 1959, the threat from the Soviet Union was perceived to be its intercontinental ballistic missiles instead of its force of long-range bombers. Against the ballistic missiles, F-108 would be completely useless and the program was cancelled in September 1959.
