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.

Applications

• Ryan AQM-34 Firebee (B/C)
• Fairchild AQM-41 Petrel
• Bell Model 65
• Fairchild C-123 Provider
• Fairchild C-82 Packet
