• Country of Origin: Russia (formerly Soviet Union). The aircraft was designed and developed by Russia's Sukhoi Design Bureau. However, it was customized specifically for India (the "I" in MKI stands for Indiski), and is manufactured under license in India by Hindustan Aeronautics Limited (HAL).
• Speed: Mach 2.0 (approximately $2,120\text{ km/h}$ or $1,320\text{ mph}$ at high altitude). This supersonic speed is achieved through advanced aerodynamics and thrust-vectoring engine nozzles.
• Payload Capacity: 8,000 kg ($17,600\text{ lbs}$). The aircraft has 12 hardpoints capable of carrying a wide array of weapons, including the BrahMos supersonic cruise missile, air-to-air missiles, guided bombs, and rockets.
• Number of Engines: 2 (Twin-Engine). It is powered by two Saturn AL-31FP turbofans, each equipped with thrust-vector control (TVC) nozzles, giving the fighter extreme maneuverability.
