Squadron Leader Chempath Chandrasekharan was commissioned in the Aeronautical Engineering (Electronics) branch of the Air Force in September, 1961. After serving for a number of years at an Operational Wing, a Ground Training School and the Air Force Technical College, he was posted to an Equipment Depot. In all these assignments, he acquitted himself well.

Since March, 1967 Squadron Leader Chandrasekharan has been serving with a Base Repair Depot. A foreign firm had demanded the sum of $ 65,000 to assign a control unit for VHF Trans-receiver fitted in an operational aircraft. An indigenous organisation had designed a Control Unit, but it did not operate satisfactorily due to design manufacturing defects. The problem was then presented to the Base Repair Depot.

Squadron Leader Chandrasekharan took up the challenge and produced a new design for the control unit. He ensured that almost the entire contents could be made indigenously. The construction was sturdy, precise and reliable under all operating conditions. Prototypes were made in six months, and passed flight trials and other tests. The Control Unit has been handed over to Messrs. Hindustan Aeronautics Limited for quantity production. The ingenuity, perseverance and technical proficiency shown in the design and development of the item has resulted in the contribution of a very reliable control unit which can be used in several types of aircraft.

In this outstanding achievement as well as throughout his career, Squadron Leader Chempath Chandrasi has rendered distinguished service of a high order.

He is awarded the Vishisht Seva Medal.
