Airforce:

The Indian Air Force(IAF; Devanāgarī: Bhartiya Vāyu Senā) is the air arm of the armed forces of India and has the prime responsibility of conducting aerial warfare and securing the Indian airspace.
It was established in 1932 as the air force of the Indian Empire[1] and the prefix Royal was added in 1945 in recognition of its services during the World War II.[2] After India

achieved its independence from the United Kingdom in 1947, the Royal Indian Air Force served the Union of India and after India became a republic in 1950, the prefix was dropped.[2]
With a strength of approximately 170,000 personnel, 1,130 combat and 1,700 non-combat aircraft in active service,[3] the Indian Air Force is the world's fourth largest.[4] In recent years, the IAF has undertaken an ambitious expansion and modernization program[5] and is increasingly used for India's power projection beyond South Asia.[6] Among the various expansion plans is the MRCA program under which the IAF plans to induct 126 fighter jets at a cost of US$12 billion.[7]
