Goa had its own proud moment during the prestigious Defexpo being held at Quitol. The defence expo is being held for the first time outside Delhi.

A huge bow mounted Sonar Dome designed and developed by Research & Development Establishment (Engineers) [R&DE(E)], a DRDO laboratory based in Pune was flagged off by Defence Minister Manohar Parrikar, Secretary Department of Defence (R&D) and DG DRDO Dr. S. Christopher were present on this important occasion.


The ceremony was held at Defexpo site in Goa and the Sonar dome will be delivered to Mazgaon Docks, Mumbai.

The Sonar Dome:

The Sonar Dome, a first of its kind in the country has been manufactured by a composites manufacturing company in India. This is a huge contribution by Indian Industry to the 'Make in India' movement. Only a couple of companies worldwide have the capability of realising such structures.

All anti-submarine warfare (ASW) ships have a sonar array fitted to the ship structure below the waterline. The sonar functions as the ship's underwater eyes and ears. The sonar dome is a structure fitted over the sonar array so that its electronics and sensors are not exposed to surrounding hostile environment. The sonar dome has to be structurally sound as well as acoustically transparent.

R&DE(E), DRDO, Pune:

R&DE(E), DRDO, Pune has successfully developed process technologies to realise large composite structures that can be used in Naval ships and submarines. The Laboratory has also developed technologies related Integral Composite Armour that can be used in Combat Vehicles.

The Laboratory is also significantly contributing in development of aerospace structures. NPOL, a DRDO Laboratory at Kochi played a significant role in development of the Sonar Dome.

It is prudent to mention that Composite Material Technologies relevant to indigenously developed Missiles have already been well established.

Other attractions at the Defexpo:

DRDO is also fielding live demonstration of number of systems with cutting edge technologies for the first time in Defexpo.
