Shown here is a smokeless Aerojet 15-KS-1000 Jet-Assisted-Take-Off (JATO) unit used to boost military and commercial aircraft. The motor produced 1,000 pounds of thrust for 15 seconds. Multiple units were used to lift bombers during the Korean War. Approximately 256,000 of these motors were produced.
Aerojet gave this motor to the Museum in 1968.
