IAF Full Form in Indian Languages

Every 8 October India marks Air Force Day, and the letters on every headline are IAF, the Indian Air Force. The cards below show the name in six Indian languages.

What the IAF is

The IAF full form is Indian Air Force. It was established on 8 October 1932 as the air arm of British India, was granted the 'Royal' prefix in 1945 after service against the Japanese in the Second World War, and dropped it when India became a republic in 1950.

Its motto, 'Nabhah Sprsham Deeptam' (Touch the Sky with Glory), is taken from the Bhagavad Gita. The roundel on its aircraft uses the saffron, white and green of the national flag. Air Force Day on 8 October is marked by a flypast and parade, often at Hindon near Delhi, though recent years have seen it held in other cities.

By size the IAF is among the largest air forces in the world, with well over a thousand aircraft of all types. The number that dominates defence debate is squadrons. After the MiG-21s were retired in September 2025, reports put the IAF at about 29 fighter squadrons against a sanctioned strength of 42, a gap that successive air chiefs have spoken about.

Structure, leadership and ranks

Headquartered at Vayu Bhawan in New Delhi, the IAF is led by the Chief of the Air Staff, who holds the rank of Air Chief Marshal. It runs seven commands: Western, Central, Eastern, Southern and South Western for operations, plus Maintenance Command and Training Command.

Operational units are organised into wings and squadrons, and a fighter squadron typically operates around 18 aircraft. Officer ranks run Flying Officer, Flight Lieutenant, Squadron Leader, Wing Commander, Group Captain, Air Commodore, Air Vice Marshal, Air Marshal and Air Chief Marshal. Marshal of the Air Force is the five-star rank, held only by Arjan Singh.

The aircraft people recognise

The backbone is the Su-30MKI, a twin-engine fighter assembled in India under licence by Hindustan Aeronautics. Alongside it flies the Dassault Rafale: 36 ordered from France, with the first five arriving in July 2019 and the last delivered in 2022.

The indigenous Tejas light combat aircraft entered squadron service in 2016 and received final operational clearance in 2019. An order for 83 Tejas Mk1A was placed in 2021, followed in 2025 by a further order for 97, to help close the squadron gap. Older types in service include the Mirage 2000, MiG-29 and Jaguar. The MiG-21, which had flown with the IAF since the 1960s, was formally retired on 26 September 2025.

Transport and helicopter fleets do the work fighters cannot: C-17 Globemasters and C-130J Super Hercules for strategic lift, Apache attack and Chinook heavy-lift helicopters inducted in 2019, and the Russian S-400 air-defence system, with first deliveries in December 2021.

How to join, and what the IAF does between wars

Officers enter through the National Defence Academy at Khadakwasla after Class 12, or through the Air Force Academy at Dundigal via the Combined Defence Services exam or AFCAT after graduation. Physics and Maths at Class 12 are needed for flying and technical streams, and the medical standard, including strict eyesight limits, filters out more candidates than the written paper does.

Airmen are recruited under the Agniveer Vayu scheme, introduced in 2022: a four-year tenure, with a quarter of each batch retained on regular service afterwards. Between operations, the IAF is the usual first responder in disasters, airlifting relief during the 2013 Uttarakhand floods in Operation Rahat, evacuating people during cyclones and maintaining logistics to high-altitude posts.

IAF, Army and Navy: telling the services apart

India's armed forces have three services: the Army, the Navy and the Air Force. Each has its own chief, its own ranks and its own recruitment channels. Air Force ranks have different names from Army ranks, even where the seniority is similar, so a Wing Commander is comparable to an Army Lieutenant Colonel.

All three come together for joint operations under the Chief of Defence Staff, a post created in 2019. The IAF's role is air defence, offensive strike, reconnaissance, airlift and support for ground forces. Examination questions often test these distinctions, along with the date of Air Force Day and the names of the commands.

The Indian Air Force has flown since 1932, from Second World War biplanes to Rafales over Ladakh. Follow the squadron strength, the seven commands and the entry routes, and defence news reads far more clearly.
