The ATF3 is a
moderate-bypass-ratio, high-pressure-ratio 3-spool turbofan. The first few
production engines were used to power the Teledyne-Ryan YQM-98 Compass
Cope RPV in 1971. Its military designation was the F104.
In 1975, the ATF3 was redesigned to improve maintainability. This engine
was selected by Dassault to power military versions of the Falcon 20 and
commercial Falcon 200.
