Marshal of the Indian Air Force Arjan Singh, (15 April 1919 – 16 September 2017) was a senior air officer of the Indian Air Force. He served as the 3rd Chief of the Air Staff from 1964 to 1969, leading the Air Force through the Indo-Pakistani War of 1965. He was the first and only officer of the Indian Air Force (IAF) to be promoted to five-star rank as Marshal of the Indian Air Force, equal to the army rank of Field Marshal.

Singh attended the Royal Air Force College Cranwell at the age of 19 and graduated in 1939. He joined the No. 1 Squadron IAF and served in the North-West Frontier Province. In World War II, he commanded this squadron during the Arakan Campaign and was awarded the Distinguished Flying Cross. In 1945, he attended the RAF Staff College, Bracknell. After the Partition of India in 1947, he led the first fly-past of Royal Indian Air Force (RIAF) aircraft over the Red Fort in Delhi. He then commanded Air Force Station, Ambala at the rank of Group Captain. In 1950, after completing the staff course at Joint Service Defence College, Latimer, Buckinghamshire, he was promoted to the rank of Air Commodore and took over the Operational Command. He commanded the Operational Command in two stints. In 1958, the post was upgraded to Air Officer Commanding-in-Chief at the rank of Air Vice Marshal.

After attending the Imperial Defence College in 1960, he served as the Air Officer in charge of Administration at Air Headquarters. In 1963, he took over as the Deputy Chief of the Air Staff and then as the Vice Chief of the Air Staff. Singh assumed office as the Chief of the Air Staff, on 1 August 1964. For his distinguished service in commanding the IAF during the Indo-Pakistani War of 1965, he was awarded the Padma Vibhushan and in 1966 became the first IAF officer to be promoted to Air Chief Marshal.

After retiring from the IAF, Singh served as a diplomat, politician and advisor to the Government of India. He served as India's Ambassador to Switzerland, the Holy See and Liechtenstein from 1971 to 1974 and as the High Commissioner of India to Kenya from 1974 to 1977. He then served as the Lieutenant Governor of Delhi from 1989 to 1990. In January 2002, the rank of Marshal of the Indian Air Force was conferred on Singh, the first and only officer of the IAF to receive the honour.

Early life and education

Singh was born on 15 April 1919 in Lyallpur (now Faisalabad), a town in the erstwhile Punjab Province of British India (in present-day Pakistan), into a Punjabi Jat Sikh family of Aulakh clan. Men from the family had joined the armed forces, in keeping with community traditions, and Singh was the fourth generation of his family to join the British Indian armed forces.

Singh's father was a Lance Daffadar in the Hodson's Horse at the time of his birth, and retired as a full Risaldar in the Cavalry, serving for a time as ADC to a Division Commander. His grandfather Risaldar Major Hukam Singh served in the Guides Cavalry between 1883 and 1917, and great-grandfather, Naib Risaldar Sultana Singh, was among the first two generations of the Guides Cavalry enlisted in 1854; he was martyred during the Afghan campaign of 1879. Thus, after three generations of men serving in the lower and middle ranks of the army, Singh was to become the first member of his family to become a commissioned officer.

Singh was educated at Montgomery, British India (now Sahiwal, Pakistan) and was a well-known sportsman. Singh then attended the Government College Lahore. He was the captain of the college swimming team and set four Punjab and four University records in swimming. He also won the All-India one-mile swimming event in 1938. Singh entered the RAF College Cranwell in 1938. At the College, he was the vice captain of the swimming, athletic and hockey teams.

Military career World War II

Singh was commissioned as a Pilot Officer in December 1939, after topping the Empire Pilot training course among his batch of Indian Cadets. He joined No. 1 Squadron which was then stationed at Air Force Station Kohat in the North-West Frontier Province (NWFP) and flew Westland Wapiti biplanes. The Squadron was conducting operations against the tribal forces in NWFP, in which he participated. While flying with the squadron in NWFP, Singh's Hawker Audax was shot down by the Pathans. He crashed in a dry stream in the midst of a fight between British troops and the Pathans. He was not hurt and within two weeks he was flying again in the same area. According to Singh, fighting in the NWFP prepared the squadron for the fight against the Japanese. He then was transferred to the newly-formed No. 2 Squadron for a brief period. He was transferred back to No. 1 Squadron in the rank of Flying Officer. By this time, the squadron had been re-equipped with Hawker Hurricane aircraft.

In 1943, Singh was promoted to acting Squadron Leader and became the Commanding Officer of No. 1 Squadron. Frustrated with watch and ward duty, Singh wanted to be in the thick of action. He met the Commander-in-Chief, India, General (later Field Marshal) Claude Auchinleck during his visit to Kohat in the North-West Frontier Province and requested him to send the squadron to fight the Japanese. The squadron was then inducted into the war and moved to Imphal in early 1944.

Singh led No. 1 Squadron into combat during the Arakan Campaign in 1944. He was awarded the Distinguished Flying Cross (DFC) in June 1944. He was presented with the DFC by Lord Mountbatten, the Supreme Allied Commander, South East Asia Command at Imphal. Singh later said about the award, “For a young man to get such a medal in front of his own squadron is a great satisfaction. I was a part of the squadron, and they were my part."

The citation for the DFC reads as follows:

Singh relinquished command of No. 1 Squadron in December 1944, handing over to Squadron Leader Ramaswamy Rajaram, who led the squadron for the rest of the Burma Campaign. Singh almost faced a court-martial in February 1945 when he tried to raise the morale of a trainee pilot (later rumoured to be the future Air Chief Marshal Dilbagh Singh) by conducting a low level air pass over a house in Kerala. In his defence, he insisted that such tricks were needed for every cadet to be a fighter pilot. Later that year, he commanded the Indian Air Force Exhibition Flight. In February 1945, Singh was promoted to the rank of Wing Commander and in August, he was selected to attend the Staff course at the RAF Staff College, Bracknell in the United Kingdom. On his return, he commanded the Air Force Station Kohat and Air Force Station Risalpur.

Post independence As part of the celebrations for Independence Day on 15 August 1947, Singh, by then an acting Group Captain, led the first fly-past of RIAF aircraft over the Red Fort in Delhi. Singh then assumed command of the frontline Airbase Air Force Station, Ambala. He led the airbase during the Partition of India. Singh subsequently moved to Air Headquarters in 1948 and tenanted the appointment of Director of Training. In 1949, Singh attended the Joint Service Defence College at Latimer, Buckinghamshire in the United Kingdom.

On his return to India, in December 1950, Singh was promoted to acting Air Commodore and assumed command of the No. 1 Operational Command (later rechristened Western Air Command). In late 1952, Singh moved to the Air Headquarters and was appointed Air Officer-in-Charge Personnel and Organisation. This appointment was later upgraded to Air Vice Marshal and then to Air Marshal, and is now termed Air Officer-in-charge Personnel (AOP). He simultaneously held the appointment of Air Officer Commanding Air Force Station New Delhi. Singh served in this appointment for three years, until December 1955.

Promoted to substantive Air Commodore, Singh again served as the AOC Operational Command, for the second time. In 1956, Singh led a squadron of Toofani jet fighters to Burma on a goodwill mission. Singh also served as the Chef de Mission of the Indian Contingent for the 1956 Summer Olympics held at Melbourne, Australia. In May 1958, Singh was promoted to the rank of Air Vice Marshal and continued as the head of the Operational Command. The appointment was upgraded to Air Officer Commanding-in-Chief (AOC-in-C) Operational Command. He led the Operational Command until November 1959, handing over command to Air Vice Marshal Erlic Pinto. Singh has the distinction of being the longest serving head of the Operational Command. He led the Command for a total of six years in two stints - December 1950 to December 1952 and December 1955 to November 1959.

Singh was selected to attend the Imperial Defence College and proceeded to United Kingdom in early 1960. After completing the year-long course, he returned to India and assumed charge as the Air Officer in Charge Administration at Air Headquarters. He tenanted this appointment through the Sino-Indian War. By the end of the war, Singh took over as the Deputy Chief of the Air Staff (DCAS), and in August 1963, he took over as the Vice Chief of the Air Staff (VCAS). As the VCAS, Singh was the overall commander of the joint air exercises "Shiksha" with the United States Air Force (USAF), Royal Air Force (RAF) and the Royal Australian Air Force (RAAF) which was held in India.

Chief of the Air Staff In May 1964, the Government of India decided to appoint Singh as the Chief of the Air Staff (CAS), succeeding Air Marshal Aspy Engineer, DFC. On 1 August 1964, Singh was promoted to the rank of Air Marshal and took over as the 6th Chief of the Air Staff. When appointed as Chief of the Air Staff of the Indian Air Force, he was around 45 years old.

Indo-Pakistani War of 1965

In August 1965, as part of Operation Gibraltar, Pakistan attempted to infiltrate forces into Jammu and Kashmir to precipitate an insurgency against Indian rule. This was followed by a full-scale war between India and Pakistan in the Western theatre. In September, Pakistan launched Operation Grand Slam in which an armoured thrust targeted the Akhnoor and Chhamb regions in Jammu. The Indian Air Force responded to an urgent call for air strikes against the Pakistani Army. Singh was summoned into the Defence Minister Y B Chavan's office with a request for air support. With a characteristic nonchalance, he replied "in an hour." True to his word, the armoured thrust was hit in an hour by the IAF. Although the IAF suffered some losses early on, it bounced back and scored strategic victories during the conflict. The war ended with a ceasefire being declared by both nations on 23 September. Singh led the IAF during the war showing unparalleled leadership and remained cool and inspirational throughout.

Singh was awarded India's second-highest civilian award, the Padma Vibhushan for his leadership during the war. On 15 January 1966, in recognition of the contribution of the IAF, the post of the CAS was upgraded to the rank of Air Chief Marshal. Singh became the first Officer to hold the rank of Air Chief Marshal.

On 7 June 1966, with the retirement of General Jayanto Nath Chaudhuri, Singh took over as the Chairman of the Chiefs of Staff Committee, a post he held until he retired. In 1967, in a rare honour to a non-British Service Chief, Singh was invited to receive the salute as the reviewing officer of the passing out parade at his alma mater, the RAF College Cranwell.

After heading the IAF for almost five years, the second-longest term as Chief of the Air Staff in history, Singh retired in July 1969, at the age of 50.

Diplomatic and political career In 1971, after his retirement, Singh was appointed India's Ambassador to Switzerland, the Holy See and Liechtenstein. He presented his credentials to the President of the Swiss Confederation, Rudolf Gnägi on 2 April 1971.
