The Sukhoi Su-30 (Russian: Сухой Су-30; NATO reporting name: Flanker-C/G/H) is a twin-engine, two-seat supermaneuverable fighter aircraft developed in the Soviet Union by Russia’s Sukhoi Aviation Corporation. It is a multirole fighter for all-weather, air-to-air and air interdiction missions.
The Su-30 started as an internal development project in the Sukhoi Su-27 family by Sukhoi. From the Su-27UB two-seat trainer, the Su-27PU heavy interceptor was developed. The design plan was revamped and the Su-27PU was renamed to Su-30 by the Russian Defense Ministry in 1996. Of the Flanker family, the Su-27, Su-30, Su-33, Su-34 and Su-35 have been ordered into limited or serial production by the Russian Defense Ministry. Later, different export requirements split the Su-30 into two distinct version branches, manufactured by competing organisations: KnAAPO and the Irkut Corporation, both of which come under the Sukhoi aerospace group’s umbrella.
Irkut traditionally served the Soviet Air Defense and, in the early years of Flanker development, was given the responsibility of manufacturing the Su-27UB, the two-seat trainer version. When India showed an interest in the Su-30, Irkut offered the multirole Su-30MKI, which originated as the Su-27UB modified with avionics appropriate for fighters. Along with its ground-attack capabilities, the series adds features for the air-superiority role, such as canards, thrust-vectoring, and a long-range phased-array radar. Its derivatives include the Su-30MKM, MKA, and SM for Malaysia, Algeria, and Russia respectively.
