The Su-30 (according to the NATO codification: Flanker-C — "Flanker-Si") is a Soviet and Russian two—seat multirole fighter of the 4+ generation.

The Su-30 is designed to destroy air targets, block enemy airfields at great depth, and strike land and sea targets. The Su-30 can also be used to control group combat operations while gaining air supremacy, destroying enemy landings in the air, as well as conducting aerial reconnaissance and destroying ground targets in simple and difficult meteorological conditions.

The Su-30 aircraft is designed according to a normal aerodynamic design with a two-keeled tail. The aircraft is similar in design and layout to the Su-27 single-seat fighter and the Su-27UB two-seat aircraft. A special feature of the aircraft is the front horizontal tail (in addition to the tail horizontal tail), which allows performing otherwise inaccessible maneuvers with a deviation of the aircraft axis from the direction of flight, as well as an integral layout with a smooth transition of the fuselage into the wing, as a result, the lifting force is created not only by the wing, but also by the body.
