Developed as an improved version of the basic Su-27 Flanker designed, the Su-37 is based on the Su-35 airframe but with thrust vectoring nozzles to give it unsurpassed maneuverability. In addition to providing more power than previous engines, the engines on the Su-37 utilize steerable nozzles which can vector the engine thrust through +/- 15 degrees of travel in the vertical axis. This thrust vectoring is fully intigrated with the aircraft's flight control systems, and requires no input or manipulation by the pilot. In the event of a system failure, an emergency system will return the nozzles to their normal position. Other modifications to the Su-37 include improved offensive and defensive avionics, an improved pulse doppler phased array radar in the nose as well as the rearward facing radar already present on the Su-34 and 35.
