The Su-37 Terminator (NATO codename: "Flanker-F") is a Russian technology demonstrator, with supermaneuverability, thrust vectoring and canards. Alongside with the Su-35 BM it is the most advanced Flanker derivative. In 1996, it was the first aircraft to perform a kulbit. The F-22 performed it later but the Kulbit was invented by the Su-37 pilots.

The Su-37 Terminator is a related development of the Sukhoi Su-35 Flanker-E, which was called Su-27M at first. Development of the Su-27M began in in the early 1980s, while the first flight of the first prototype was in 1988. The differences in comparison with the Su-27P are the Canards, to boost manoeuvreability, more powerful engines, a new radar and a digital fly-by-wire system. In newer prototypes the cockpit was also redesigned. In the year 1993, the Su-27M was renamed to Su-35.

Actually the Su-37 Terminator is a Su-35 that was upgraded with 2D thrust vector control. Testing and the first flights of the Su-37 began in April 1996. The Su-37 was unveiled at the Farnborough Air Show 1996, where it was flown by testpilot Jevgeni Frolov.
