Group Captain Mukund Chatterjee was commissioned in the Air Force in 1953. He has served in Squadrons, Wings and Staff appointments with distinction. His contribution as Senior Armament Officer of No. 2 Wing was significant. In 1968, he was commended by Air Officer Commending-in-Chief, Western Air Command, for his contribution in the operational preparedness of Canberra aircraft. In December 1979, he was posted as Joint Director of Engineering (C) at Air Headquarters and was assigned the responsibility of providing complete maintenance support to Gnat, Ajeet and Marut aircraft. Ajeet aircraft was introduced into the Service in November, 1978, but its gunnery system was not functioning satisfactorily. M/S. Hindustan Aeronautics Limited, who were responsible for the design of this aircraft, could not rectify the defect despite their best efforts. Group Captain Chatterjee, who was assigned the responsibility to study the complete gunnery system of the aircraft and suggest remedial measures, conducted static and air­to­ground firing trials from various ranges away from his base. Eventually he succeeded in finding out the causes of the gun stoppages. After the modifications suggested by him had been carried out, the gunnery system of the aircraft has become satisfactory.

Group Captain Chatterjee has thus rendered distinguished service of an exceptional order.
