The Fairchild J44 was a small turbojet developed in the 1940s by the Fairchild Engine Division.

Design and development

The Fairchild Engine Division (previously the Ranger Aircraft Engine Division of the Fairchild Engine & Aircraft Corporation) began development of the J44 in 1947. It was used in target drones, missiles, and as jet boosters on several aircraft types.
