India’s Defense Research and Development Organisation (DRDO) is making significant strides in underwater warfare technology with the development of an advanced Air-Independent Propulsion (AIP) module. This innovative system promises to significantly enhance the endurance and capabilities of Indian submarines.
The DRDO’s AIP module utilizes phosphoric acid fuel cells, each generating a robust 13.5 kW of power. While this output meets the immediate needs of the Kalvari-class submarines (currently requiring up to 15.5 kW), DRDO is setting its sights even higher. Recognizing the need for future submarine classes like the P-76, they’re spearheading the development of a larger AIP module capable of generating a scaled-up 20 kW.
The DRDO’s AIP module has already undergone successful land-based prototype testing, paving the way for real-world implementation. The Kalvari class is slated to receive the first AIP module next year, although this integration will necessitate a 10-meter extension and a two-year period for submarine-based trials.
Looking ahead, the P-76 class promises to be a true game-changer. These next-generation submarines, boasting a displacement of nearly 3,000 tons (over 1,000 tons more than the Kalvari class), will demand even greater power. To meet these demands, the P-76 will incorporate advanced lithium-ion battery technology, further bolstering its underwater endurance.
