History of Tierra Amarilla AFS, NM'

An AN/CPS-5 radar was activated in 1950 at the El Vado Lashup location (L-44) near the dam. The unit was later installed at the permanent site several miles to the north-northeast that was activated to provide coverage for Los Alamos. By September 1952, the 767th AC&W Squadron commenced operation at this new permament site. By 1953 AN/FPS-3 and AN/FPS-5 radars were in operation. A year before the site shutdown, the AN/FPS-5 was replaced by an AN/FPS-6 height-finder radar. On 8 December 1958 (or 1 July 1961?), this became the first radar of the permanent network to shutdown.
