The DRDO tech that will make Indian submarines more silent and lethal

Air Independent Propulsion allows a submarine to be submerged for longer periods underwater and makes the sub-surface platform more deadly by making it quieter than a nuclear submarine.

In a major boost to India's Aatmanirbhar Bharat campaign, the Defence Research and Development Organization has carried out the final development test of Air Independent Propulsion in Mumbai. 

It is pertinent to mention here that INS Karanj attack submarine will be inducted into the Indian Navy on March 10. This is the third in the series of six submarines being built by Mazagon Dock Shipbuilders.

AIP allows a submarine to be submerged for longer periods underwater and makes the sub-surface platform more deadly by making it quieter than a nuclear submarine. Fuel cell-based AIP has merits in performance compared to other technologies.

"The plant was operated in endurance mode and max power mode as per the user requirements. The system is being developed by Naval Materials Research Laboratory," the DRDO said.

While there are different types of AIP systems being pursued internationally, fuel cell-based AIP of NMRL is unique as the hydrogen is generated onboard, it said.

Supported by the L&T and Thermax in its development, the AIP has now reached the stage of maturity for fitment into target vessels.

So far only the US, France, China, UK and Russia have this technology. Defence Minister Rajnath Singh congratulated DRDO, Indian Navy and Industry for the achievement.
