Associated Launch Sites
  • Edwards Edwards Air Force Base, originally known as Muroc Field, is the main test flight centre for the US Air Force. It has been used since the 1940's for flight test of advanced aircraft, rocketplanes, and air-dropped aerospace vehicles launched from B-29, B-50, B-52, F-15, 747 or L-1011 carrier aircraft. More...
  • Rosamund Dry Lake DZ Air-launched rocket drop zone known to have been used for 18 launches from 1959 to 1960, reaching up to 26 kilometers altitude. More...
  • Eglin This US Air Force proving ground and missile test range, based in Valparaiso, Florida and extending over a vast expanse of the Gulf of Mexico, was founded in 1935, In early 1946 the First Experimental Guided Missiles Group was activated at Eglin. The highly-instrumented Eglin Gulf Test Range supported flight tests of Bomarc, Matador, Quail, and Hound Dog cruise missiles. Both the military and NASA used Eglin to support launch of sounding rockets in support of their programs. Eglin was known to have been used for 441 launches from 1959 to 1980, reaching up to 686 kilometers altitude. The actual number of missile tests was many times greater. More...
