From UPSC perspective, the following things are important :
Prelims level : AIP system
Mains level : Indigenization of defense production
- DRDO is a step closer to boosting endurance of submarines with the indigenous Air Independent Propulsion (AIP) System.
- It has successfully tested the operation of the indigenous land-based prototype.
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.
- AIP can augment or replace the diesel-electric propulsion system of non-nuclear vessels.
- It enables conventional submarines to remain submerged for longer duration.
