AN/FPS-74
AN/FPS-74 was operating in S-Band frequency-diverse gap-filler radar.
In October 1960, USAF established a program to modernize all existing SAGE gap filler sites and to equip all programmed SAGE gap filler sites with the AN/FPS-74. The program called for a total of 182 FPS-74’s — 137 in the U.S. and 45 in Canada. Originally, Budd Electronics, the contractor, was to install the first set by 1 October 1962 and it was to be operational by 1 January 1963. However, the program fell far behind because Budd failed to produce satisfactory equipment. USAF advised on 20 January 1964 that the FPS-74 program would be cancelled.
The prototype, which had functioned reasonably well up to that point, was subsequently made available for research projects.
