Flight Lieutenant Apramjeet Singh was commissioned in the Flying Branch of the Indian Air force in June 1963. During the Indo-Pakistan conflict of December, 1971, he flew 21 operational sorties consisting of escort and sweep missions, deep inside enemy territory. On 8th December 1971, while flying as Number two in the Chhamb Sector, his formation encountered heavy enemy ground fire in which his leader was shot down. His aircraft was also hit and sustained heavy damage. Despite the fact that the aircraft had become almost uncontrollable, due to damage to its port wing, and many other systems becoming unserviceable, he displayed exemplary skill and courage in bringing his aircraft back to base safely.
In this action, Flight Lieutenant Apramjeet Singh displayed gallantry and professional skill of a high order.
