The Su-37 has a variety of other innovative equipment such as a radar configured for simultaneous surveillance of airspace and the ground and a high-precision laser-inertial/satellite navigation system. The all-weather digital multi-mode phased array radar operates in either air and ground surveillance modes or in both modes simultaneously. Ground surveillance modes include mapping (with Doppler beam sharpening), search-and-track of moving targets, synthetic aperature radar and terrain avoidance. The Su-37 is also equipped with a rearward facing radar in the tail stinger area of the fuselage. The Su-37 features fly-by-wire and relaxed static instability, which along with 3D thrust vectoring give the aircraft tremendous agility. It incorporates state of the art ECM in wing-tip pods, allowing improved survivability in electronic warfare environments. The Su-37 can carry air-to-air and air-to-surface weapons on 12 stations. The number of missiles and bombs carried can be increased to 14 with the use of multi-payload racks.
Sukhoi used payments earned in the sale of an Su-27 license to China to finance the Su-37 development. Russia's Air Force has not ordered any Su-37s. Sukhoi is studying the possibility of developing a two-seat version of the Su-37 with enhanced strike capabilities.
