IRDE starts work to develop periscopes

Scientists of the premier Instruments Research and Development Establishment (IRDE) have started working on indigenously developing state-of-the-art periscopes for the submarine fleet of the Indian navy and the project is likely to be completed in two years.

At present, the defence ministry depends on foreign firms for procurement of the periscopes for the submarine. In 2016, an international firm supplied seven periscopes at a total cost of Rs 145.63 crore.

The costly maintenance of the equipment pushed the IRDE to develop the periscopes. IRDE director Benjamin Lionel said, β€œIt is a long term project and nothing much can be discussed.”

A submarine sails about 350m deep under the sea and to use the periscope it goes up just 30m below the seawater.

The periscope is the eyes and ears of the submarine and its visual sensors facilitate safe navigation, collision avoidance, and surveillance of targets as well as torpedo attacks in high-sea operations.
