The YF-20 is a Chinese liquid-fuel rocket engine burning N 2 O 4 and UDMH in a gas generator cycle. It is a basic engine which when mounted in a four engine module forms the YF-21 .

The Northrop F-20 Tigershark (initially F-5G) is a prototype light fighter, designed and built by Northrop.Its development began in 1975 as a further evolution of Northrop's F-5E Tiger II, featuring a new engine that greatly improved overall performance, and a modern avionics suite including a powerful and flexible radar.
The two YF-23s flew 50 times for a total of 65.2 hours. [69] The tests demonstrated Northrop's predicted performance values for the YF-23. [57] Both designs met or exceeded all performance requirements; the YF-23 was stealthier and faster, but the YF-22 was more agile. [70] [64] A YF-22 in the foreground with a YF-23 in the background
