This airfield was described by Tom in his letter of June 24, 1944, as the location used by his squadron mates for an emergency landing after running out of gas on a training mission.
At that time, the airfield was closed for general use because it was being used for secret testing of jet propulsion aircraft. Today, it is still involved in secret building and testing of aircraft and is the location of “United States Air Force Plant 42”.
The origins of Plant 42 go to the early 1930s, when a small airstrip was built in the desert. It was listed in 1935 documentation as CAA Intermediate #5. It was established by the Bureau of Air Commerce (later the Civil Aeronautics Administration) who maintained a network of emergency landing fields. It provided a pilot in distress with a better alternative than landing on a public road or a farmer’s field.[4]
World War II
In 1940, Palmdale Army Airfield was activated as a United States Army Air Corps (later Air Forces) airfield for use as an emergency landing strip and for B-25 Mitchell medium bomber support training during World War II. It was one of many intermediate fields that were used as auxiliary fields or emergency landing fields by the AAF during World War II. Their dispersion along the air routes, their infrequent use, and their U.S. government ownership made them ideal for use by military aircraft. It acted as a sub-base for Muroc Army Airfield and Hammer Army Airfield.[4]
Postwar use
Palmdale Army Airfield was declared a surplus facility in 1946 and was purchased by Los Angeles County for use as a municipal airport. The outbreak of the Korean War in 1950 caused the Air Force to reactivate the property for use in final assembly and flight testing of military jet aircraft.
Both the Air Force and its aircraft contractors needed a location away from major population centers – due to sonic booms, other noises and security concerns – but close enough to the major centers of aircraft design and production, while having excellent flying weather the year around. The land which became Plant 42 fit these criteria. Consequently, the Air Force agreed to purchase the land from Los Angeles County in 1951.
The Air Force awarded a contract to Lockheed Aircraft to develop the master plan for the site. The plan was to construct a facility that would meet the requirements of full war mobilization and augment the industrial production potential of the major airframe manufacturing industry in southern California.
The concept for Air Force Plant 42 originated in the challenge of flight testing high performance jet aircraft over heavily populated areas. Following approval of the Master Plan in 1953, the Palmdale Airport officially became Air Force Plant 42; ownership of the installation was transferred to the Federal Government in 1954. With USAF encouragement, Lockheed, looked upon with favor by the Air Force at this time, established its permanent presence at Plant 42. It signed a lease in 1956 for 237 acres to use Palmdale Airport for final assembly and flight testing.
Lockheed Skunk Works
Lockheed’s famed “Skunk Works” (black projects), which developed such aircraft as the U-2, SR-71 Blackbird and F-117 Nighthawk, is at Site 10 of the complex (actually private property with secure access to Plant 42 airfield), near Sierra Highway, and relocated to Plant 42 from its original Burbank-Glendale-Pasadena Airport (now Bob Hope Airport) site in Burbank after the end of the Cold War. Its present hangar was constructed in 1968 and the outer walls of the structure were put up in a matter of days. Its hangar originally was built for the Lockheed L-1011 Tristar passenger jet project.
Since then, the plant has supported facilities for the production, engineering, final assembly and flight testing of high performance aircraft. During the 1980s it was used by Lockheed to produce the U-2/TR-1 and support the SR-71. Northrop produced the F-5E, and Rockwell supported the B-1B Lancer. Past projects included:
- Each of the Space Shuttle orbiters
- Modernization of the Space Shuttle Columbia‘s cockpit area
- Lockheed L-1011 Tristar passenger jet
- B-1 Lancer Bomber
- XB-70 Valkyrie
- X-15
- SR-71 Blackbird
- F-117A Nighthawk
