Artist's conception of AN/FPS-24 tower and antenna.
General Electric built an FD search radar designed to operate in the Very High Frequency (VHF) at 214 to 236 MHz. There were problems with this radar at the test site at Eufaula, Alabama, in 1960. These problems required many modifications. Additional problems occurred when deployment was attempted in 1961. When the radar finally deployed, bearing problems often occurred due to the eighty-five ton antenna weight. Twelve systems were built between 1958 and 1962.

Only one of two AN/FPS-24 radars to be successfully covered with a radome was at Cottonwood AFS, ID, pictured here. The other was at Mount Hebo AFS, OR.
