Cheli Air Force Station

Cheli Air Force Station, in Bell, southeastern Los Angeles County, California, was a United States Air Force installation and a Cold War Radar Bomb Scoring site of the Strategic Air Command, from 1947 to 1961.^[1]

It was originally a U.S. Army Air Forces depot, from 1943, during World War II, to 1947. Since its closure, in 1961, has housed facilities of the United States Postal Service, United States Army Reserve, and the California Army National Guard.^[1]

The 91.48 acres (37.02 ha) military site was established as the Maywood Army Air Forces Specialized Storage Depot in 1943 during World War II, and was part of Air Materiel Command.^[1] The function of the depot was to store and distribute aircraft parts. The site was transferred to the United States Air Force (USAF) when it became a separate service branch from the Army Air Force in 1947.^[1]

Cheli Air Force Station was named when the military installation was transferred to the USAF in 1947, in honor of San Francisco born Medal of Honor recipient Major Ralph Cheli.^[1][2]

Cheli AFS had 31 military and 1,139 civilians on 30 June 1958.^[3]

The Los Angeles Bomb Plot, or LA Bomb Plot #7 or Los Angeles RBS, was a Radar Bomb Scoring (RBS) site of the Radar Bomb Scoring Division, established at Cheli Air Force Station c. 1952, for evaluating bomber training missions on practice targets in Southern California.^[4][5] The site was first controlled by Detachment 8 of the 3903rd Radar Bomb Scoring Group in 1952, redesignated the 11th Radar Bomb Scoring SQ in 1953,^[6] which was commanded by Lt Col James O. McHan.^[7]

The Los Angeles Bomb Plot RBS site was near Beale AFB, Castle AFB, and March AFB bomber bases, as well as the Brown Field Bombing Range, Camp Beale Bombing Range, Madera Bombing Range, Muroc Bomb & Gunnery Range, Saline Valley Bombing Range, and Trabuca Bombing Range.^[8] Bomb run locations included those of a Castle AFB bomber using the "A/B Santa Barbara" Initial Point and the " LA # 'I' " target.^[4]

The radar site closed in 1961, after the Los Angeles RBS unit moved to a Wall, South Dakota RBS site, located at the Badlands Bombing Range which had opened in August 1960.^[6]
