The Sukhoi Su-30MKI is an air superiority fighter jointly developed by Russia's Sukhoi and India's Hindustan Aeronautics Limited (HAL) for the Indian Air Force (IAF).
A variant of the Sukhoi Su-30, it is a heavy, all-weather, long-range fighter.
Development of the variant started after India signed a deal with Russia in 2000 to manufacture 140 Su-30 fighter jets.
The first Russian-made Su-30MKI variant was accepted into the Indian Air Force in 2002, while the first indigenously assembled Su-30MKI entered service with the IAF in 2004.
The IAF has 157 Su-30MKIs in active service as of January 2012; it plans to have a fleet of 272. The Su-30MKI is expected to form the backbone of the Indian Air Force's fighter fleet to 2020 and beyond.
The aircraft is tailor-made for Indian specifications and integrates Indian systems and avionics as well as French and Israeli subsystems. It has abilities similar to the Sukhoi Su-35 with which it shares many features and components.
