Sukhoi After the war, Sukhoi and his team were among the first Soviet aircraft designers who led the work on jet aircraft, creating several experimental jet fighters. Sukhoi started developing two jet fighters, the Sukhoi Su-5 and the Sukhoi Su-7 before 1945. The Su-5 is a mixed power jet fighter, using both a propellor and a motorjet to power it, but the experiment was later cancelled even though the fighter had a maiden flight in April 6, 1945.

According to the Sukhoi Design Bureau, Su-30MKK is the first of the Flanker family to achieve it after Su-35 / 37 (Flanker-E/F) and Sukhoi Su-30MKI. Higher percentage of composite material is used for Su-30MKK in comparison to the original Su-30MK. In addition, new aluminum alloy were used to replace the old type used on Su-30MK for weight reduction. The twin rudders mainly made of carbon fiber composite material were larger on Su-30MKK in comparison to that of the original Su-30MK, but contrary to what was once
