DRDO press release
The plant was operated in endurance mode and max power mode as per the user requirements. The system is being developed by Naval Materials Research Laboratory (NMRL) of DRDO.
AIP has a force multiplier effect on lethality of a diesel electric submarine as it enhances the submerged endurance of the boat, several folds. Fuel cell-based AIP has merits in performance compared to other technologies.
While there are different types of AIP systems being pursued internationally, fuel cell-based AIP of NMRL is unique as the hydrogen is generated onboard.
The technology has been successfully developed with the support of industry partners L&T and Thermax. It has now reached the stage of maturity for fitment into target vessels.
Raksha Mantri Shri Rajnath Singh congratulated DRDO, Indian Navy and Industry for the achievement.
Secretary DDR&D and Chairman DRDO, Dr G Satheesh Reddy appreciated the efforts of the teams involved in the successful development. He called upon the DRDO fraternity to come up with more such advanced technological achievements by putting extraordinary efforts.

Naval News comments:
As previously reported, Naval Group India engineers are already working with the DRDO for the integration of an Indian designed AIP module. Initially, the 5th and 6th submarine should have received an AIP plug. But due to delays in the propulsion module design at DRDO, it was later decided that the AIP plug will be retrofitted to each Kalvari-class submarine during their first normal refit that occurs every 7 years. The AIP plug will bring the length of the Scorpene/Kalvari-class from 67,56 meters to 77,56 meters.
