DRDO is developing AIP technology, Indian subs to be more quiet and lethal: On 8 March, DRDO successfully proved the ground-based prototype of the Air Independent Propulsion (AIP) system. The plant was run in endurance and max power mode as per user requirements. DRDO reached a significant milestone in the production of the AIP system by demonstrating the land-based prototype on Monday. The plant was run in endurance and max power mode as per user requirements. The device is being designed by the DRDO Naval Materials Research Laboratory (NMRL).
The advancement of AIP technology is a major boost to the Atma Nirbhar Bharat campaign, because only the United States, France, China, the United Kingdom and Russia have this main technology. The AIP technology of the DRDO is based on the Phosphoric Acid Fuel Cell and the last two Kalvari class submarines will be operated by it. The AIP concept was tested on the ground in Mumbai on Monday night, the last of a series of tests. DRDO’s AIP technology has also been tapped in the back by the French, who were in contact with the Indians in the Kalvari class of production. Despite urgent demands, the French decided not to upgrade Agosta 90 B Pakistani submarines with AIP technology, forcing Islamabad either to go to China or to Turkey.
