Recently the Défense Acquisition Council approved Rs 50,000 crore for project 75I. Under this project, six conventional submarines equipped with state-of-the-art air-independent propulsion will be indigenously built.The submarines will be built under the strategic partnership model, in which Larsen and Toubro & Mazagon Dockyards Limited will be the strategic partners to build the submarines in partnership with foreign firms.5 companies have been shortlisted for this bid, which are: Rubin Design Bureau of Russia, French Naval Group, Spain's Navantia, Germany's TKMS, DSME of South Korea .But it is going to take almost 2 years to select the winner of this bid. Now if we talk about today's news, then the Indian Navy has refused to include the AIP system developed by DRDO in the submarines being built in P75I. The AIP system is considered a very useful system for diesel attack submarines. Batteries, usually used to operate underwater in diesel-electric submarines, have to come to the surface to be recharged. The 'air-independent propulsion' (AIP) is the ability to operate and recharge submarines' batteries without the use of atmospheric oxygen. In the month of March this year, DRDO demonstrated a land based prototype of his AIP system, which was being seen as a great achievement of DRDO. Its prototype has been made jointly by DRDO's NMRL, L&T and Thermax. DRDO's AIP is based on a 270KW fuel cell that allows submarines to stay underwater for 2 days in maximum power mode and 14 days in endurance mode.But the question arises that when DRDO has proved the capability of its AIP, then why Indian Navy does not want to install this system in the submarines to be built under Project 75I. Does the Indian Navy not trust DRDO or the aip system created by DRDO is not as effective? We will try to answer all these questions in this video. So, stay tuned with us till the end of this video. So let me tell you it is not like that. DRDO's AIP has just been tested on a land-based prototype. At the same time, it has not been tested in any submarine yet. The Indian Navy wants DRDO to retrofit its AIP system into the Navy's Scorpene class submarines first. Once DRDO proves its capability, only then it will be allowed to integrate the AIP system in the submarines to be built under Project-75I. Therefore, the Indian Navy will allow the contenders of Project-75I to use its AIP system. So what is understood from this is that the Indian Navy is running here with a balanced approach. While the navy is allowing DRDO to install its AIP system in Scorpene class submarines, it does not want to take any risk in the construction of project-75I submarines and is allowing foreign OEMs to install their own AIP systems.Once the AIP system made by drdo will be tested and only after its success, they can also be allowed to be integrated into the submarines of the Indian Navy.

Why no to DRDO's AIP System in project 75-I submarines ?
