This is the Aerobee 350, the last and largest of the family of solid-fuel boosted liquid-propellant Aerobee sounding rockets for undertaking short-term scientific experiments in the upper atmosphere. The Aerobee 350 carried payloads of 150-500 pounds up to altitudes of 294 and 207 miles, respectively.
The rocket used a cluster of four standard Aerobee 150 motors with a total thrust of 18,844 pounds. This specimen lacks its booster. The Aerobee program produced about a dozen models and lasted from 1947 to 1985. It obtained data on upper atmospheric densities, compositions, radiations, micrometeorites, airglow spectra, aurora phenomena, and astronomical phenomena.
This object was transferred to the Smithsonian in 1997 from the U.S. Air Force Museum.
