     Naval Systems: India has over 7000 km of
maritime boundary. Recognising the importance of        Naval Materials Research Laboratory (NMRL)
this strategic asset, DRDO has three laboratories
working exclusively for naval applications,                  NMRL Ambernath, under its present charter
keeping in mind the requirements for weapons            has been pursuing basic research as well as
and sensors of our naval forces. The sphere of          application oriented technology development in
activity covers sonar systems, torpedoes and            several frontier areas like metallurgy, polymer,
anti-torpedo systems/weapons and materials              ceramics, coating, corrosion, electrochemical
for naval applications. The labs are:                   protection, marine biology and environmental
                                                        sciences. NMRL has been given the status of
