This is the Sleighride rocket sled, which was used at Holloman Air Force Base, New Mexico, in 1952-1953 for testing the impact behavior of timers, batteries, fuses, and other components of missiles and bombs. Additionally, it tested the effect of rain against bomb and missile radomes during simulated high speed flights. The rains in the tests were simulated by sprinklers. The sled is fitted with a radome in front and five inert 2.5-KS-18,000 Aerojet-General solid fuel JATO (Jet-Assisted-Take-Off) rocket motors which produced a total of 90,000 pounds of thrust for 2.5 seconds.
The Sleighride was transferred to the Smithsonian in 1967 by the U.S. Army.
