The first JATO was tested using an ERCO Ercoupe plane (of the Engineering and Research Corporation) in July 1941.In 1943, von Kármán, Malina, Parsons, and Forman established the Aerojet Corporation to manufacture JATO rockets. The project took on the name Jet Propulsion Laboratory in November 1943, formally becoming an Army facility operated under contract by the university.
