- The indigenous Air Independent Propulsion (AIP) system to enhance the endurance of conventional submarines being developed by the Defence Research and Development Organisation (DRDO) reached a milestone on October 30, 2019 with the successful operation of a land-based prototype.
- All Scorpene submarines of the Navy are planned to be equipped with an AIP module in due course.
Air Independent Propulsion (AIP) System:
- Air-independent propulsion (AIP) is any marine propulsion technology that allows a non-nuclear submarine to operate without access to atmospheric oxygen (by surfacing).
- AIP is usually implemented as an auxiliary source, with the traditional diesel engine handling surface propulsion.
- Most such systems generate electricity which in turn drives an electric motor for propulsion or recharges the boat’s batteries.
- Fuel cell-based AIP has merits in performance compared to other technologies
- AIP can augment or replace the diesel-electric propulsion system of non-nuclear vessels.
- It enables conventional submarines to remain submerged for longer duration.
