Made from aluminum, Cherokee was a blocky, simple design that was designed for air-launch from a B-29 bomber. It was operated as part of Project Whoosh, an effort to determine if the use of ejection seats at supersonic speeds was feasible.
Launched from the B-29 mothership at an altitude of 6 miles (9.7 km) 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. 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. 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.
