New-2009 - Indian Air Force - भारतीय वायु सेना - Bhartiya Vāyu Senā

The Indian Air Force (IAF; Devanāgarī: भारतीय वायु सेना, Bhartiya Vāyu Senā) is the air arm of the armed forces of India. Its primary responsibility is to secure Indian airspace and to conduct aerial warfare during a conflict. It was officially established on October 8, 1932 as an auxiliary air force of the Indian Empire and the prefix Royal was added in 1945 in recognition of its services during the World War II. After India achieved independence from the United Kingdom in 1947, the Royal Indian Air Force served the Union of India, with the prefix being dropped when India became a republic in 1950.

Since independence, the IAF has been involved in four conflicts with neighboring Pakistan and one with the People's Republic of China. Other major operations undertaken by the IAF include Operation Vijay, Operation Meghdoot and Operation Cactus.

The President of India serves as the Commander-in-Chief of the IAF. The Chief of Air Staff, an officer with the rank of Air Chief Marshal, commands the Air Force. There is usually only one serving officer of that rank at any given time in the IAF. One officer has been conferred a 5-star rank, that of Marshal of the Air Force.

With strength of approximately 170,000 personnel and 1,700 aircraft, including 852 combat aircraft in active service, the Indian Air Force is the world's fourth largest.[2][3] In recent years, the IAF has undertaken an ambitious expansion and modernisation program to replace its aging Soviet-era fighter jets. 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.
