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. When India showed interests in the Su-30, Irkut offered the multirole Su-30MKI, which originated as the Su-27UB modified with avionics appropriate for fighters. 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. It is a fighter with both air supremacy and attack capabilities, generally similar to the U.S. The Chinese chose an older but lighter radar so the canards could be omitted in return for increased payload. Due to KnAAPO's involvement from the early stages of developing the Su-35, these are basically a two-seat version of the mid-1990s Su-35.
KnAAPO manufactures the Su-30MKK and the Su-30MK2, which were designed for and sold to China, and later Indonesia, Uganda, Venezuela, and Vietnam. 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.
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. The design plan was revamped and the Su-27PU was renamed to Su-30 by the Russian Defense Ministry in 1996. From the Su-27UB two-seat trainer, the Su-27PU heavy interceptor was developed. The Su-30 started as an internal development project in the Sukhoi Su-27 family by Sukhoi. It is a multirole fighter for all-weather, air-to-air and air interdiction missions. 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.
