India’s push to strengthen the endurance and stealth of its submarine fleet received a boost on Thursday with INOX India Ltd (INOXCVA) flagging-off of a first-of-its-kind simulated Liquid Oxygen (LOX) storage module for the Indian Navy’s indigenous Air Independent Propulsion (AIP) system.

Developed by INOXCVA at its Kalol facility in Panchmahal district, the module will undergo Factory Acceptance Tests as part of the AIP programme led by the Naval Material Research Laboratory (NMRL), a key DRDO lab based in Ambernath in Maharashtra’s Thane district, a statement said.

The cryogenic LOX storage tank, designed for the ground-based prototype of the AIP system, plays a critical role in enabling submarines to remain submerged for longer durations without surfacing. Engineered to store oxygen in liquid form at extremely low temperatures, the system meets stringent standards of safety, purity and reliability required for defence applications, the statement said.

The module was flagged off by NMRL Director Dr Suman Roy Choudhury and INOXCVA CEO Deepak Acharya. INOXCVA’s role in the strategic programme includes design, engineering, fabrication and testing of the specialised tank.

Acharya said the milestone reflects the company’s contribution to “mission-critical systems” supporting India’s defence capabilities. “The AIP programme represents a critical advancement in enhancing the endurance and stealth of our submarines, and we are honoured to support it with our specialised cryogenic expertise. This achievement reflects our commitment to delivering high-precision, mission-critical systems that uphold the highest standards of safety, reliability, and engineering excellence in service of the nation.”

The AIP project is seen as a key step towards enhancing the operational capabilities of India’s conventional submarine fleet.
