Pete has made very minor word changes for clarity and added links, where useful. Pete cautions that all this information about France-India may still be an Indian bargaining ploy to beat down the price of a German TKMS Type 214 to win India's Project-75(I or i) competition.
[AIP, Kalvari and Project-75(I or i)]
1. Instead of the Blackshark heavyweight torpedo (HWT) it will be [mainly French developed] F21 for Scorpenes, Arihants and future P75i SSK with derived technology going into India's Varunastra HWT to make it more lethal.
The Amur 1650 or Lada Russia proposed is not cutting much ice with the Indian Government. In fact [India’s] Reliance Defence and Engineering Ltd had submitted a proposal to build 12 Kilo 636 in Pipavav [Shipyard, Gujarat, India] with first 2 being built in Russia and next 10 in India. GOI did not even look into it till this date.
The reason is straight and simple, the product line which comes in P75i should have features which are the latest technology available in the market and which can be fed into Indian SSN/SSBN programs.
French and Indian cooperation will be unprecedented. I am sure you will see a lot more of a new Australia-France-India troika in submarines.
A NOTE OF CAUTION - TKMS?
India has a pattern of not buying subs from the same country twice - not having bought from Germany since the 1980/90s. It is also TKMS that is likely to have the mature fuel cell AIP that India wants for P75i. So beating down the price of 6 Type 214 (or 218s) from TKMS for P75i may be India's long term objective.
