 Sri TR Natarajan, obtained his MSc from Madras University,DIIT in Rubber Technology from Kharagpur, and MBA from IGNOU, New Delhi. He joined DRDO  in 1968 at Defence Laboratory (DL), Jodhpur and joined Naval Science & Technological Laboratory (NSTL), Visakhapatnam in 1969. As head of the Rubber Technology Group, he achieved break-through in design of rubber recipes and successfully developed rubber components for underwater weapons AET, WGT, mines and flexible fuel tank for thermal propulsion system. He also developed shock and vibration mounts for various IN ships and electrical locomotives hitherto imported.

He has been responsible for establishing, implementing and maintaining quality systems standards at NSTL leading to ISO 9001 certification. He is an associate member of the Indian Institute of Metals, Kolkata and Lead Assessor for ISO 9001 from BSI (UK) . He is the recipient of Technology Group Award- 2002.

 Shri K Kondal Rao joined DRDO in 1968 at Defence Electronics Research Laboratory (DLRL), Hyderabad. Later, he joined Naval Science & Technological Laboratory (NSTL) , Visakhapatnam in 1971 to work in the field of Underwater Missiles viz. Torpedoes. In 1984, he led a full-fledged system design and engineering team to convert a non-homing torpedo into a homing torpedo which has been successfully demonstrated.

A state-of-the-art anti-submarine light weight torpedo was designed, integrated and successfully evaluated which culminated in users placing atrial production order for five numbers of D&E models. The technology was transferred to the private sector by the team led by Shri Kondal Rao. The production models have been successfully proven and the AET Team has bagged the prestigious Agni Award.
