Made from aluminum,[1] Cherokee was a blocky, simple design that was designed for air-launch from a B-29 bomber.[2] It was operated as part of Project Whoosh, an effort to determine if the use of ejection seats at supersonic speeds was feasible.[3]
Launched from the B-29 mothership at an altitude of 6 miles (9.7 km)[4] it would fire a solid-fueled rocket to accelerate to supersonic speed, at which point the ejection seat, containing an anesthetized chimpanzee as a test subject, would be fired.[3] The first test took place on January 26, 1954, at Edwards Air Force Base; another test in June was held before the project moved to Holloman Air Force Base, with two further tests being carried out in July 1955 and April 1956.[5] None of the four chimpanzees used in the tests survived due to difficulties with the ejection system, however the project was considered a partial success.[5]
