Purpose:

• The primary aim of the Su-30MKI is to maintain air dominance over the Indian subcontinent.

Key Features:

• Super Maneuverability: Equipped with thrust-vectoring nozzles and canards, allowing the aircraft to perform extreme maneuvers (like the Cobra) that are impossible for standard fighters.

• Advanced Avionics: Features a hybrid of international technology, including a powerful passive electronically scanned array (PESA) radar (being upgraded to Indian Uttam AESA radar) and sophisticated electronic warfare suites.

• Weaponry & Range: It is the only aircraft in the world capable of carrying the BrahMos-A supersonic cruise missile. It can carry a massive 8,000 kg combat payload, including Astra (BVR), R-77, and Kh-59 missiles.
