134-470: A V-1 flying-bomb-style weapon that never left the drawing board, the track found use after the war as a test area for V-2 rockets captured from Nazi Germany in Operation Paperclip . Later, Lt. Col. John Stapp appropriated the track for his MX981 project and installed what was believed to be one of the most powerful mechanical braking systems ever constructed. His deceleration tests led

201-533: A high plateau at Edwards. By the time the base was officially designated the U.S. Air Force Flight Test Center in June 1951, more than 40 different types of aircraft had first taken flight at the base and the nation's first generation of jet-powered combat airplanes had already completed development. One of them, the North American F-86 Sabre , was dominating the skies over Korea. The promise of

268-625: A methodical fashion to answer largely theoretical questions. Then, as now, the great bulk of flight testing at Muroc focused on evaluations of the capabilities of aircraft and systems proposed for the operational inventory. In December 1949, Muroc was renamed Edwards Air Force Base in honor of Captain Glen Edwards (1918–1948), who was killed a year earlier in the crash of the Northrop YB-49 Flying Wing. During World War II , he flew A-20 Havoc light attack bombers in

335-482: A month later, Major Chuck Yeager topped this record as he piloted the second-generation Bell X-1A to a top speed of Mach 2.44 (2,989 km/h; 1,857 mph) and, just nine months later, Major Arthur "Kit" Murray flew the same airplane to a new altitude record of 90,440 feet (17.129 mi; 27.57 km). These records stood for less than three years. In September 1956, Captain Iven Kincheloe became

402-616: A new aviation record by piloting the first non-stop, around-the-world flight on a single tank of fuel in the Rutan Voyager . Extensive aviation research was also conducted on the ground at Edwards. Two rocket sled tracks pioneered important developments and research for the Air Force. The first 2,000-foot (610 m) track was built by Northrop in 1944 near what is currently the North Base. Originally intended to help develop

469-599: A peak altitude of 74,494 feet (14.1087 mi; 22.706 km). Then, in 1953, Marine Corps test pilot, Lieutenant Colonel Marion Carl , flew the same plane to an altitude of 83,235 feet (15.7642 mi; 25.370 km). On 20 November 1951, the National Advisory Committee for Aeronautics' Scott Crossfield became the first man to reach Mach 2 as he piloted the Skyrocket to a speed of Mach 2.005 (2,456.2 km/h; 1,526.2 mph). Less than

603-554: A replica of a Japanese cruiser, nicknamed " Muroc Maru ", was constructed in Rogers Dry Lake where it was used for bombing training until 1950. With the end of the war, Fourth Air Force relinquished command of Muroc Army Airfield on 16 October 1945 and jurisdiction was transferred to Air Technical Service Command , becoming Air Materiel Command in 1946. Test work on the Lockheed P-80 Shooting Star

670-471: A search for a new, isolated site where a "Top Secret" airplane could undergo tests "away from prying eyes." The urgent need to complete the P-59 program without delay dictated a location with good, year-round flying weather, and the risks inherent in the radical new technology to be demonstrated on the aircraft dictated a spacious landing field. After examining a number of locations around the country, they selected

737-585: A single accident and, though the aircraft did not prove to be combat worthy, the successful conduct of its test program, combined with the success of the Lockheed XP-80 program which followed it in early 1944, sealed the future destiny of the remote high desert installation. Muroc would thenceforth become synonymous with the cutting edge of the turbojet revolution in America. Aircraft testing continued at this desert "Army Air Base", then on 8 November 1943,

804-605: A site along the north shore of the enormous, flat surface of Rogers Dry Lake about six miles away from the training base at Muroc. Ground tests began five days after the first XP-59 arrived on 21 September 1942. First flight took place on 30 September when the XP-59 rose to 10 feet (3.0 m) altitude for 0.5 miles (0.80 km) during taxi testing. However, the first official flight was 1 October 1942 with NACA, Navy Bureau of Aeronautics, Royal Air Force , Army, Bell and General Electric personnel on hand. As with virtually all of

871-524: A testing site for experimental airplanes. The success of these programs attracted a new type of research activity to the base in late 1946. The rocket-powered Bell X-1 was the first in a long series of experimental airplanes designed to prove or disprove aeronautical concepts—to probe the most challenging unknowns of flight and solve its mysteries. Further evidence of things to come was experienced on 14 October 1947 when Captain Charles "Chuck" Yeager flew

It also hosts many test activities conducted by America's commercial aerospace industry. Notable occurrences at Edwards include Chuck Yeager 's flight that broke the sound barrier in the Bell X-1 , test flights of

1139-517: The B-2 Spirit bomber represented third-generation stealth technology, following the SR-71 and F-117. The 1980s also saw Edwards host a demonstration of America's space warfare capabilities when a highly modified F-15 Eagle launched an ASM-135 anti-satellite missile at the dead P78-1 (or Solwind) satellite and destroyed it. In 1986, Dick Rutan and Jeana Yeager launched from Edwards to set

1206-485: The North African campaign on 50 hazardous, low-level missions against German tanks, convoys, troops, bridges, airfields, and other tactical targets. Edwards became a test pilot in 1943 and spent much of his time at Muroc Army Air Field, on California's high desert, testing wide varieties of experimental prototype aircraft. He died in the crash of a Northrop YB-49 flying wing near Muroc AFB on 5 June 1948. From

1474-542: The 21st century. It also supported the development of the extremely high-altitude and long-range Lockheed U-2 and the dazzling ultra-performance capabilities of the B-58 Hustler , the world's first Mach 2 bomber. Throughout the 1950s, American airplanes regularly broke absolute speed and altitude records at Edwards, but nothing compared to the arrival of the North American X-15 in 1961. The program got under way in earnest in 1961 when Maj. Robert M. "Bob" White became

1541-587: The 4144th Air Force Base Unit was re-designated as the 2759th AF Base Unit and with the adoption of the Hobson Plan , as the 2759th Experimental Wing. With the X-1, flight testing at Muroc began to assume two distinct identities. Highly experimental research programs—such as the X-3, X-4, X-5 and XF-92A—were typically flown in conjunction with the National Advisory Committee for Aeronautics, or NACA, and were conducted in

1608-592: The 78th and 81st Fighter Groups. In 1943, the 360th Fighter Group and 382d Bombardment Groups were assigned permanently to Muroc for P-38 Lightning and B-24 Liberator Replacement Training (RTU) of personnel. In the spring of 1942, the Mojave Desert station was chosen as a secluded site for testing America's first jet, the super-secret Bell Aircraft P-59 Airacomet jet fighter. The immense volume of flight tests being conducted at Wright Field, in Ohio, helped drive

1675-655: The B-52 synthetic fuel program , the C-17 Globemaster III , and many prototype unmanned aerial vehicles (UAVs). Edwards is among the few U.S. military bases to have gained jobs since the Cold War. Under the DoD's Base Realignment and Closure process, several smaller bases have been decommissioned, and their facilities and responsibilities have been sent to Edwards, China Lake , and other large bases. During 2012,

1742-549: The Center at the time of activation were the 6510th Air Base Wing for station support units. The test flying units at Edwards were assigned directly to the AFFTC . That same year, the U.S. Air Force Test Pilot School moved to Edwards from Wright Field, Ohio. Its curriculum focused on the traditional field of performance testing and the relatively new field of stability and control, which had suddenly assumed critical importance with

1809-724: The Leuhman Ridge east of Rogers Dry Lake on Edwards AFB. Construction began in November 1949 on what was to become the Experimental Rocket Engine Test Station. Jurisdiction of Edwards AFB was transferred from Air Materiel Command on 2 April 1951 to the newly created Air Research and Development Command . Activation of the Air Force Flight Test Center (AFFTC) followed on 25 June 1951. Units designated and assigned to

1876-597: The Muroc Bombing and Gunnery Range, Muroc Lake, California, was designated as a separate post (Exempted Status). The name of the facility at the time was "Army Air Base, Muroc Lake." In July 1942, Muroc Army Airfield became a separate airfield from March Field and was placed under the jurisdiction of Fourth Air Force . Throughout the war years, the primary mission at Muroc was providing final combat training for bomber and fighter aircrews just before overseas deployment. Among its sub-bases and auxiliaries were: Muroc

1943-524: The Persian Gulf conflict of the early 90s. The Low Altitude Navigation and Targeting Infrared for Night, or LANTIRN, system revolutionized air-to-ground combat operations during the same conflict by denying opposing forces the once comforting sanctuary of night. The late 1980s also witnessed the arrival of the first giant flying wing to soar over the base in nearly 40 years. The thin silhouette, compound curves and other low-observable characteristics of

2010-659: The Raptor, the F-22A continues to undergo test and evaluation at Edwards. A new group of research projects came to Edwards in the 1990s. Global Hawk , an unmanned aerial vehicle that has been used extensively in Afghanistan and Iraq, made its first flight at Edwards in February 1998. The X-24, X-33, X-34, X-36 and X-38, a series of new lifting bodies, technology demonstrators and half-scale models were tested here by NASA during

2077-531: The Space Shuttle landed follows the route that hosted racing in the 1930s. The first major aerial activity occurred at Muroc in 1937 when the entire Army Air Corps participated in a large-scale maneuver. From then on, the bombing range grew in size. When Arnold became Chief of the Air Corps in 1938, the service was given a renewed focus on research and development . Muroc Field drew attention because

Most of the base sits in Kern County , but its eastern end is in San Bernardino County and a southern arm

2211-585: The X-15 Program, AFFTC and NASA also teamed up to explore a new concept called "lifting reentry" with a series of wingless lifting body aircraft. These rocket powered-vehicles – the M2-F2, M2-F3, HL-10, X-24A and X-24B – paved the way for the Space Shuttle and future spaceplane designs when they demonstrated that they could make precision landings after high-speed gliding descents from high altitude. The major aircraft systems that were tested and developed during

2278-510: The X-37 program, including in-flight evaluation of guidance, navigation and control software for its autonomous flight controls. One test flight the craft was towed by an Army CH-47D Chinook helicopter to an altitude of 15,000 feet, and then released to fly an autonomously controlled 75-second descent to a landing on the main runway at Edwards Air Force Base , where it then glided and guided itself. Data from Boeing X-40A - National Museum of

2345-407: The afternoon of 7 December 1941 , the 41st Bombardment Group and the 6th Reconnaissance Squadron moved to Muroc from Davis-Monthan Army Airfield , Arizona , with a collection of B-18 Bolos , B-25 Mitchells , and an A-29 Hudson . On Christmas Eve, the 30th Bombardment Group and the 2d Reconnaissance Squadron arrived from New Orleans Army Airbase , Louisiana , for crew training. On 23 July 1942,

2412-522: The area, and when a post office was commissioned for the area, they named it Muroc, a reversal of the Corum name, due to the presence of a town named Coram. Conscious that March Field was located in an area of increasing growth in Riverside County , and with the need for bombing and gunnery ranges for his units, base and 1st Wing commander Lieutenant Colonel Henry H. "Hap" Arnold began

2479-548: The base title was changed to "Muroc Army Air Field, Muroc". In the fall of 1944, Eighth Air Force ran tests to determine how well conventional fighters stood up against jets. Also, in October 1944, a small detachment arrived at the base for experimental work in rocket firing and achieved such success that they remained through most of 1945. Other World War II test flights included the Northrop JB-1 Bat . In 1943,

2546-516: The contractor's reports, this preliminary evaluation consisted of a very limited number of flights and was essentially completed within a month. Formal operational suitability and accelerated service tests did not get underway until 1944, well after the AAF had decided that the airplane would not be suitable for combat operations and would, instead, be relegated to a training role. The P-59s were tested at Muroc from October 1942 through February 1944 without

2613-624: The decade. The new millennium brought new projects with worldwide impact. The X-35A and X-32A, competing models for the Joint Strike Fighter program, made their first flights in September and October 2000. The X-35A won the competition in 2001 and will eventually be built in various versions for America's flying armed services and for foreign air forces as well. Also new are the RQ-4 Global Hawk , YAL-1 Airborne Laser ,

2680-479: The desert. For the next two years aircraft shuttled back and forth between Muroc Dry Lake and March Field for Crew Bombing Practice. At this time, another colorful character in Edwards' history, Pancho Barnes , built her renowned Rancho Oro Verde Fly-Inn Dude Ranch that would be the scene of many parties and celebrations to come. The dry lake was a hive of hot rodding, with racing on the playa. The runway on which

2747-572: The development of a new subsonic attack aircraft that was designated the F-117A Nighthawk. The capabilities of existing aircraft such as the F-15 and F-16 have been continually refined and expanded, even as totally new aircraft and systems incorporating radical new technologies are developed for future operational use. The dual-role F-15E, for example, was developed in the 1980s and went on to demonstrate truly remarkable combat effectiveness in

2814-458: The dramatic increases in speed offered by the new turbojets. As the decade opened, the first-generation X-1 reached Mach 1.45 (1,776 km/h; 1,104 mph) and a 71,902 feet (13.6178 mi; 21.916 km) altitude, representing the edge of the envelope. The D-558-II Douglas Skyrocket soon surpassed these marks. In 1951, Douglas test pilot Bill Bridgeman flew the Skyrocket to a top speed of Mach 1.88 (2,303 km/h; 1,431 mph) and

2881-518: The duration of the shuttle program. Shuttles landed at Edwards as recently as 9 August 2005 ( STS-114 ), 22 June 2007 ( STS-117 ), 30 November 2008 ( STS-126 ), 24 May 2009 ( STS-125 ), and 11 September 2009 ( STS-128 ) due to rain and ceiling events at the KSC Shuttle Landing Facility . STS-126 was the only mission to land on temporary runway 04 at Edwards, as the refurbished main runway was operational from STS-119 through to

2948-480: The first man to exceed Mach 4, as he accelerated to Mach 4.43 (5,427 km/h; 3,372 mph) on 7 March. He claimed Mach 5 just three months later when he pegged a speed of Mach 5.27 (6,456 km/h; 4,012 mph) on 23 June and then, during the X-15's first full-powered flight on 9 November, he exceeded Mach 6, as he flew to a speed of Mach 6.04 (7,399 km/h; 4,598 mph). Major White also became

3015-458: The first man to fly an airplane in space when he climbed to 314,750 feet (59.612 mi; 95.94 km) on 17 July 1962. NASA's Joe Walker flew the airplane to its peak altitude of 354,200 feet (67.08 mi; 108.0 km) on 22 August 1963 and Maj William J. "Pete" Knight reached Mach 6.72 (8,232 km/h; 5,115 mph) in the modified X-15A-2 on 3 October 1967, a speed that remains the highest ever attained in an airplane. In addition to

3082-527: The first man to soar above 100,000 feet (19 mi; 30 km), as he piloted the Bell X-2 to a then-remarkable altitude of 126,200 feet (23.90 mi; 38.5 km). Flying the same airplane just weeks later on 27 September, Captain Mel Apt became the first to exceed Mach 3 (3,700 km/h; 2,300 mph), accelerating to a speed of Mach 3.2 (3,920 km/h; 2,440 mph). His moment of glory

3149-413: The nearby dry lake was so flat (Arnold described it as "level as a billiard table") that it could serve as a giant runway, ideal for flight testing. Over US$ 120 million was spent to develop the base in the 1940s and expand it to 301,000 acres (470 sq mi; 1,220 km ). The base's main 15,000-foot (4,600 m) runway was completed in a single pour of concrete. Download coordinates as: On

3216-479: The press to nickname him the "fastest man on earth" and the "bravest man in the Air Force". The results from the first track prompted the Air Force to build a second in 1948. Located just south of Rogers Lake, the 10,000-foot (1.9 mi; 3.0 km) track was capable of supersonic speeds. Its first project was the development of the SM-62 Snark cruise missile . This track was so successful that an extension

3283-486: The process of acquiring land next to Muroc Dry Lake for a new bombing range away from populated areas in August 1932; the last tract was not acquired until 1939. The facility established to support the range, initially called "Mohave Field" for the nearby community of Mohave , was Muroc Field. In October 1935, five men under a Sergeant Folgleman were sent to the area from March Field. They put out circular bombing targets in

3350-468: The prophecy concerning the ever-increasing importance of systems testing and integration. Moreover, another major new element of complexity was soon introduced into the flight test process. At a remote location in 1978 and 1979, an AFFTC test pilot and a pair of flight test engineers were engaged in proof-of-concept testing with Lockheed's "low-observable" technology demonstrator, dubbed "Have Blue." The successful completion of those tests led immediately to

3417-424: The proposed guidance system . The first X-40A drop test occurred at Holloman AFB , New Mexico on August 11, 1998 at 06:59. It was released from an altitude of approximately 10,000 feet (3,000 m) and 2.5 miles (4.0 km) away from the end of Runway 04 by a UH-60 Black Hawk helicopter (later tests used an Army CH-47D Chinook helicopter). The vehicle dove to the runway in an approach similar to

After that time, Kennedy Space Center (KSC) in Florida was favored. This saved the considerable cost of transporting the shuttle from California back to Florida, but Edwards AFB and White Sands Space Harbor continued to serve as backups for

3752-547: The small bullet-shaped airplane to become the first human to exceed the speed of sound. Four months later, on 10 February 1948, Muroc AAF was re-designated Muroc Air Force Base with the establishment of the United States Air Force as a separate military service. Units attached or assigned to the base at the time were the 4144th Army Air Force Base Unit, the 3208th Strategic Bomb Test Squadron along with communications and weather detachments. On 20 August 1948,

Although Army Air Forces (AAF) pilots flew the aircraft from time to time, and flight test engineers from Wright Field reviewed the data, the formal preliminary military test and evaluation program did not commence until the Fall of 1943, a year after the first flight. Designed to validate

3886-462: The time Edwards Air Force Base was named, speed and altitude records began to pile up as new aircraft were developed and the base started to build and branch out significantly. A major reason for the growth of Edwards AFB was the nearness of West Coast aircraft manufacturers. However, another major reason was the decision in 1947 to build a missile test facility on the base. The need for a static missile faculty to test high-thrust missile rocket engines

3953-463: The turbojet revolution and the supersonic breakthrough were realized in the 1950s, as the Center tested and developed the first generation of true supersonic fighters—the famed "Century Series" F-100 Super Sabre , F-101 Voodoo , F-102 Delta Dagger , F-104 Starfighter , F-105 Thunderchief and F-106 Delta Dart , and, in the process, defined the basic speed and altitude envelopes for fighter aircraft that still prevail to this day. The Center also played

After the Navy had conducted research on the UGM-27 Polaris ballistic missile , the track was used to develop ejection seats that could be used at supersonic speeds. Though this program was a success, a budgetary review concluded that the track was too expensive to maintain, and the track

4221-456: Was decommissioned on 24 May 1963. Before it was closed, a trial run set a world speed record of Mach 3.3 (4,040 km/h; 2,510 mph) before the test car broke up. After it closed, the rails were pulled up to help straighten Lancaster Boulevard. After President Richard M. Nixon announced the Space Shuttle program on 5 January 1972, Edwards was chosen for Space Shuttle orbiter testing. The prototype Space Shuttle Enterprise

4288-402: Was first envisioned in 1946 by the Power Plant Laboratory at Wright-Patterson Air Force Base . It was that decision that such a facility should be government-owned to prevent a single contractor exclusive advantages on Air Force contracts for high-thrust missile rocket power plants, and it would eliminate duplication of like facilities by different manufacturers. The choice of location in 1947 was

4355-450: Was initially used for IV Bomber Command Operational Unit training. The B-25 Mitchell 41st and 30th Bombardment Groups and the A-20 Havoc 47th Bombardment Groups trained at the station in early 1942. The training provided newly graduated pilots eight to 12 weeks of training as a team using the same aircraft they would use in combat. In 1942, the training mission was transferred to IV Fighter Command , with P-38 Lightning OTU training for

4422-403: Was the primary mission of the base for the greater part of the fall of 1945.
