The AN/FPS-35 Long Range Search Radar, built by the Sperry Gyroscope Company, was one of several frequency diversity radars developed for the Air Defense Command and for the SAGE (Semi Automatic Ground Environment) System. The FPS-35 was first deployed in 1960, but was not operational until 1962. Frequent bearing problems plagued this radar because the antenna weighed more than 70 tons. Twelve FPS-35 radars eventually became operational in the Continental United States.. For more information from Radomes.org's virtual museum, click here.
