Sukhoi Su-37 what would result in the Su-30MKI, which is a two-seat fighter design that incorporated the canards, N011M radar and thrust-vectoring technology that were present and evaluated on the Su-37. In addition, through tests of the Su-27M and the Su-37, engineers had determined that thrust vectoring could compensate for the loss of manoeuvrability brought about by the removal of canards, the design of which imposed a weight penalty on the airframe. The modernized Su-35, without canards, made its first flight in February 2008. Sukhoi Su-37 The Sukhoi Su-37 (-37; NATO reporting name: "Flanker-F") is a single-seat twin-engine aircraft designed by the
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.
