DRDO: Indian submarines set for indigenous edge in open seas - The Economic Times
An indigenously developed air-independent propulsion (AIP) system, set to be fitted on the first submarine next year, will significantly increase underwater endurance. It will add stealth to conventional submarines and enhancing operational effectiveness by allowing them to stay submerged for...m.economictimes.com
This has disaster written all over it.
DRDO designing a totally new AIP with no past experience of SSK subs
Cutting open a foreign sub and installing it
Length and weight increases to a design that has not been validated for it
Either this project will flounder or be subject to very very long delays.
Easier would have been to let France install a AIP and let DRDO develop one and use an old Indian Submarine as a test bed.
France will not accept any liability for this project either
