India's diesel-electric submarines will now stay submerged longer thanks to the indigenous Air Independent Propulsion (AIP) system developed by DRDO. The second phase of the AIP energy module began at L&T's Hazira facility in Gujarat, inaugurated virtually by Defence Secretary Rajesh Kumar Singh. The system allows submarines to charge batteries underwater, reducing exposure to enemy detection and increasing underwater endurance.
