The Indian Air Force was established in 1932 as an auxiliary air force of the British Empire. It played a key role in several wars including the Indo-Pakistani wars of 1947, 1965, and 1971. Today it is the fourth largest air force in the world with over 127,000 personnel and 1,370 aircraft. The IAF operates fighter jets like the Sukhoi Su-30MKI, Mirage 2000, and Tejas, as well as transport aircraft and helicopters. Its primary missions are to secure Indian airspace and provide air support during conflicts.
