The Communications-Electronics Command (CECOM) can trace its roots to the establishment of a Signal Corps training facility and radio research and development laboratory at Fort Monmouth, New Jersey in 1917. The installation was granted permanent status and was renamed Fort Monmouth in August 1925. It was named in honor of the soldiers of the American Revolution who died in the battle of Monmouth Court House.
Serving as the "Home of The Signal Corps," Fort Monmouth was a major Signal Corps training site during World War II. The scientists of the Signal Corps laboratories developed, among many other things, the first U.S. aircraft detection radar. Personnel also proved space communications feasible in 1946 when the Diana Radar bounced electronic signals off the moon.
