The Indian Navy on Friday inducted four types of indigenously developed sonar systems to boost its underwater surveillance capabilities, PTI reported. Sonar is a technique that uses sound to detect objects under water. Defence Minister Manohar Parrikar handed over the four sensors to the Navy.
They include Abhay, which can be mounted on the hulls of smaller vessels, Humsa UG, an upgraded version of the older Humsa sonar system, one named NACS (Near-field Acoustic Characterisation System), and the last one called AIDSS (Advanced Indigenous Distress Sonar System for Submarines).
Defence Research and Development Organisation’s Naval Physical and Oceanographic Laboratory, which is based out of Kochi, have designed the systems. Parrikar said he expected more such projects to be undertaken between the organisations in the future.
