History of Madera, CAMadera began as a Lashup site, LP-74, operating an AN/TPS-1B in March 1951. The 774th AC&W Squadron began operating AN/FPS-3 and AN/FPS-4 radars from this location in January 1952. In 1958 the height-finder radar was replaced by AN/FPS-6 and AN/FPS-6A radars. In 1959 an AN/FPS-20 search radar superseded the AN/FPS-3. In 1960 the Air Force upgraded an AN/FPS-6A to become a -6B, and integrated the site into the SAGE system. The Air Force then upgraded the search radar, first to an AN/FPS-20A, and then to an AN/FPS-66. By 1963 this AN/FPS-66 search radar operated in conjunction with AN/FPS-6 and AN/FPS-90 height-finder radars. This site was inactivated on June 25, 1966.
