SU37

The SU-37, identified by its NATO reporting name Flanker-F, was a Russian twin-engine, multirole fighter aircraft developed by Sukhoi. It was an advanced derivative of the Su-27 Flanker family, designed to incorporate thrust vectoring control and other enhancements to significantly improve maneuverability and combat capabilities. The prototype first flew in 1996.

Key features of the SU-37 included its advanced aerodynamic design, the integration of thrust vectoring nozzles on its Saturn AL-37FP engines, and a sophisticated avionics suite. These thrust vectoring capabilities allowed for exceptional agility, enabling post-stall maneuvers and high angle of attack flight regimes that were virtually impossible for conventional aircraft. The aircraft also featured a glass cockpit with multi-function displays.

While the SU-37 showcased impressive technological advancements and potential, it remained a technology demonstrator. Due to economic constraints and evolving military requirements in Russia, the program did not proceed to full-scale production. Despite not entering service, the SU-37's innovations, particularly its thrust vectoring technology, heavily influenced subsequent Sukhoi designs and contributed to the development of other advanced Russian fighter aircraft. Its development represented a significant step in exploring extreme maneuverability in fighter aircraft design.
