Aerobee

The Aerobee rocket was one of the United States' most produced and productive sounding rockets. Developed by the Aerojet Corporation, the Aerobee was designed to combine the altitude and launching capability of the V-2 with the cost effectiveness and mass production of the WAC Corporal. More than 1000 Aerobees were launched between 1947 and 1985, returning vast amounts of astronomical, physical, aeronomical, and biomedical data.

The flight would breach the boundary of space (as defined by the World Air Sports Federation) Research using V-2 rockets after World War II produced valuable results concerning the nature of cosmic rays, the solar spectrum, and the distribution of atmospheric ozone. However, the limited supply and the expense of assembling and firing the V-2 rockets, as well as the small payload capacity of the first purpose-built sounding rocket, the WAC Corporal, created demand for a low cost sounding rocket to be used for scientific research. An Applied Physics Laboratory (APL) effort led by James Van Allen led to a contract presented 17 May 1946 by the Naval Research Laboratory (NRL) to Aerojet, at the time a producer of WAC Corporal rockets, for the procurement of 20 liquid-fueled sounding rockets capable of carrying a payload to an altitude of . 15 of the new rockets would be allocated to APL, and 5 to NRL. Aerojet was to be the prime contractor while Douglas Aircraft, also a producer of WAC Corporals, would provide aerodynamic engineering and take on some of the production.
