The Su-30 started out as an internal development project in the Sukhoi Su-27 family by Sukhoi. The design plan was revamped and the name was made official by the Russian Defense Ministry in 1996. Of the Flanker family, only the Su-27, Su-30, Su-34 and Su-35 have been ordered into serial production by the Defense Ministry. All the others, such as Su-37, were prototypes.
The Su-30 has two distinct version branches, manufactured by competing organisations: KnAAPO and the Irkut Corporation, both of which come under the Sukhoi group's umbrella. KnAAPO manufactures the Su-30MKK and the Su-30MK2, which were designed for and sold to China, and later Indonesia, Venezuela and Vietnam. Due to KnAAPO's involvement from the early stages of developing Su-35, these are basically a two-seat version of the mid-1990s Su-35.
The Chinese chose an older but lighter radar so the canards could be omitted in return for increased payload. It is a fighter with both air superiority and attack capabilities, generally similar to the U.S.F-15E.[3] The Sukhoi Su-35 (Russian: Сухой Су-35; NATO reporting name: Flanker-E) is a designation for two separate heavily-upgraded derivatives of the Su-27 'Flanker'. They are single-seat, twin-engine supermaneuverable multirole fighters, designed by Sukhoi and built by Komsomolsk-on-Amur Aircraft Production Association (KnAAP
