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.
