Flight Lieutenant Peruvamba Ramakrishnan Narayana Murthy was commissioned in the Administrative Branch of the Indian Air Force in December, 1964. He was employed as a fighter controller at a signal unit in the forward area during the Indo-Pak conflict in December, 1971.

On 9th December, 1971 he was instrumental in detecting three impending strikes at a forward air base and thus ensured timely tactical action by the base against the air attack. Again on 11th and 14th December, 1971, it was because of his diligence and professional competence that our own strike missions were warned in time to take evasive/offensive action against interception of enemy aircraft. Also on 11th December, 1971, it was due to his vigilance that our ground forces near Chor took defensive positions against air attacks well in time thus preventing many casualties.

Throughout his career, Flight Lieutenant Peruvamba Ramakrishnan Narayana Murthy has displayed great professional skill and ingenuity and thus rendered distinguished service of a high order. For this, he is awarded the Vishisht Seva Medal.
