The other variant developed as the export version for India, the "Su-30MKI" ('Flanker-H') was delivered in 2002 and has at least five other configurations.

Sukhoi Su-30MKI demonstrator and Su-30 program, being more advanced than the Su-30MK and the Chinese Su-30MKK/MK2. Russia's Defence Ministry was impressed with the type's performance envelope and ordered 30 Su-30SMs, a localised Su-30MKI, for the Russian Air Force. It features state of the art avionics developed by Russia, India and Israel for display, navigation, targeting and electronic warfare; France and South Africa provided other avionics. After two years of evaluation and negotiations, on 30 November 1996, India signed a US$1.462 billion deal with Sukhoi for 50 Russian-produced Su-30MKIs in five batches. The first batch were eight Su-30MKs, the basic version of Su-30.
