Su-37

The Su-37 is a super-maneuverable thrust vectoring fighter derived from an Su-35 prototype. The Su-37 represents a new level of capability compared with the Su-27 and Su-35. The Su-37 test aircraft made its maiden flight in April 1996 from the Zhukovsky flight testing center near Moscow. This impressive single-seat all-weather counter-air fighter and ground attack aircraft, derived from the SU-27, has an updated airframe containing a high proportion of carbon-fibre and Al-Li alloy. The engines, avionics and armaments are also improvements on those originally installed in the SU-27. The AL-37FU engines are configured for thrust vector control, with the axisymmetric steerable thrust vector control nozzle is fixed on a circular turning unit. The steel nozzle in the experimental engines is replaced in production engines by titanium units to reduce the weight of the nozzle. The nozzle only moves in the pitch axis, and the nozzles on the two engines can deflect together or differentially to achieve the desired thrust vector for a particular maneuver.

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.
