Development and design
The J97 was based on GE's General Electric GE1/J1 series of turbojets and the engine development was financed by the United States Air Force.[1] The original application was to be the Northrop P-530 (which later evolved into the YF-17), but it was ultimately only used in several small drone aircraft.[2]
