Blythe Airport (IATA: BLH, ICAO: KBLH) is a public airport located six miles (9.7 km) west of Blythe, serving Riverside County, California, USA. The airport has two runways and is mostly used for general aviation.
The airfield was opened in April 1940. During World War II the airfield was known as Bishop Army Airfield and was used by the United States Army Air Forces.
The field was built for the I Troop Carrier Command but was given up by that command, without ever occupying it, to the 4th Air Force as a California-Arizona Maneuver Area (CAMA) training field. The 46th Bomb Group and later the 34th Bomb Group occupied the field during the CAMA days and flew a variety of planes including B-17s, B-24s, A-31s and A-36s. Blythe Army Air Field later became a sub-base of Muroc Army Air Field (now Edwards Air Force Base)
Known units assigned to Blythe Army Airfield were:
- 46th Bombardment Group (Light) 23 May 1942-November 1942. A-20 Havoc
