  • Wac Development of the JPL-Ordnance WAC began in 1944. In 1946 it became the first American rocket to exceed 80 km altitude (above the earth's atmosphere as defined by publicity of the time). It was capable of taking 11 kg to 30 km altitude and was powered by a liquid propellant engine originally developed for JATO applications. More...

Associated Launch Sites
  • White Sands White Sands Missile Range occupies an area 160 x 65 km in the Tularosa Basin of southern New Mexico, across the Sacramento Mountain range from Roswell. In the 1930's, Robert Goddard, after surveying weather conditions and population densities, had selected Roswell for his pioneering rocket tests. White Sands, a true desert area, was even more unpopulated than Roswell. German advances in rocketry during World War II impelled the US Army to begin programs to exploit this technology. The White Sands Proving Ground was established for testing German and American long-range rockets on 9 July 1945. Seven days later the first atomic bomb was exploded at Trinity Site, near the north boundary of the range. The first launch of a Tiny Tim rocket was on 26 September 1945. On 11 October a Tiny Tim boosted a WAC Corporal rocket from the tower. This was the first use of Launch Complex 33, later to be used for V-2, Nike, Viking, Corporal, Lance and Multiple Launch Rocket System testing. More...
  • White Sands LC33 Wac, Viking, V-2, Nike, Javelin, Hermes, Corporal, Atlas, Apache launch complex. LC 33 was the United States' first major rocket launch facility. The original Army Launch Area 1 complex consisted of a blockhouse, several concrete launching pads for captured German V-2 rockets, a 30-m tall launch tower for Aerobee rockets, a gantry and blast pit.

WAC A Chronology


1945 October 11 - . Launch Site: White Sands. Launch Complex: White Sands LC33. LV Family: Wac. Launch Vehicle: WAC A. LV Configuration: WAC A 5.
  • Test mission - . Nation: USA. Agency: USA OR. Apogee: 72 km (44 mi). Summary: First 'all-up' Wac Corporal launch. Recovery system failed..

1945 October 12 - . Launch Site: White Sands. Launch Complex: White Sands LC33. LV Family: Wac. Launch Vehicle: WAC A. LV Configuration: WAC A 6.
  • Test mission - . Nation: USA. Agency: USA OR. Apogee: 72 km (44 mi). Summary: The parachute failed, but the nose cone also came off. This set the rocket on a tumbling re-entry, providing sufficient braking that it hit the ground pretty well intact..
