Based on the two-seat Su-27UB trainer and originally known as the Su-27PU, the Sukhoi Su-30 is a long-range precision-attack fighter similar to the F-15E Eagle series. Although retaining the air-to-air interceptor capabilities of the Su-27, the early Su-30 and Su-30K models are optimized for long-endurance missions of 10 hours or so. These aircraft are ... fitted with a radiolocation system that allows them to transmit the positions of up to 10 targets to four other aircraft simultaneously. This feature makes the Su-30 suitable as a tactical fighter leader designating targets to be attacked by other aircraft. These variants were later joind by the multi-role Su-30M model that adds precision ground attack capability while carrying a range of advanced guided bombs and missiles.

Su-35BM will be the last developed Flanker. An final upgrade, final variant. Actually, the designation is quite confusing, since Su-35 already exists in Russian Air Force. Su-35 was the export designation for upgraded Su-27, called Su-27M, internal Sukhoi designation T-10M. Su-27M gave baseline Flanker new avionics, as well as precision air-to-ground capability. Only five of these are in service with VVS (Russian Air Force), with 237th regiment based at Kubinka Air Base.

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 aperture radar and terrain avoidance. The Su-37 is ... 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 2D thrust vectoring give the aircraft tremendous agility. In the 1980’s General Designer Mikhail P. Simonov insisted that the Su-37 be equipped with axisymmetric vectoring nozzles instead of the 2D vectoring nozzles.

The Su-34 has a changed contour of the nose section to accommodate an advanced multi-mode phased array radar with terrain following and terrain avoidance modes. It has a two-seat rather than single-seat cockpit. The capacity of the internal fuel tanks has been increased with a resulting increased take-off weight. Changes have been made to the central tail boom for a rear-facing radar.

The Su-37's astounding maneuvers included the "Super Cobra", demonstrated for the first time. In this move, the aircraft enters with a speed of 400 kmh and is pulled through to an alpha of 135 degrees, then recovered to the vertical and held in place for 4-6 seconds. The nose is then allowed to fall to the horizontal position, emerging at 150kmh with no loss of height. Another used the thrust vectoring to flip the Su-37 onto it's back (a full 180 degress), and then to rotate it upright and continue in the opposite direction. The most impressive maneuver was the kulbit (somersault). With an entry speed of 350 kmh the aircraft flipped onto it's back, a 180 degree flip facing the opposite direction, inverted and practically stationary.

In 1993 Sukhoi converted the first series produced Su-30 into a demonstrator to market the multi-role version designated Su-30MK. MK standing for Modernizirovannyi Kommercheskiy ('modified commercial') indicating that this new version was developed especially for the export market. Centerpoint of the new version would be an upgraded multirole fire control system, depending on the customer's requirements. The air-to-ground capability of the aircraft is effectively greatly enhanced and a large variety of new guided missiles and bombs were added to the armament options. For the air-to-air role, the new RVV-AE (R-77) medium-range active radar homing missile was added to the options.
