Air Independent Propulsion (AIP) System


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.
