Why aren't we ordering next subs..
Production won't get idle?

The Scorpene project is ending with 6 subs because its current configuration is already outdated, it was supposed to be inducted between 2012 and 2017. The navy needs larger, more capable subs that can patrol regions thousands of kilometers away from their base, which will come with the new tender.

Isn't DSME the only contender remaining now (since TKMS withdrew)?

There are four contenders for the Indian Navy's next generation P75I submarine. They are currently submitting design proposals to the Indian government. Whatever the outcome, the boats should all be built in India. The deal will therefore take into account political and industrial considerations as well as naval requirements.

The four competitors are the Barracuda from France, the S-80-Plus from Spain, the DSME-3000 from South Korea and Amur design from Russia. Germany had also been a candidate, but recently said it had dropped out.

Sorry, got mistaken with the number of contenders.

1. The French Barracuda may not have a French AIP (the Attack class proposal didn't). And the Amur/Lada class doesn't have an AIP either. So is there a possibility that the DRDO AIP under-development might be used, should these designs get selected?

2. Is the plan to refit the Scorpenes with the Indian AIP still on?

Do you have any idea on when we can expect the P75I submarine contract to be awarded (assuming IN wants the first sub by 2027-28, they'll need to start construction within 1-2 years)?

This deal is Naval group to loose now. Orherwise none other option meets all the requirements(considering VLS for SLCM and AIP are two of them).

No way to tell anything right now. Gotta wait for official announcement.

If the IN wants actual evaluations, particularly AIP, then it would take years, most of the 4 left will fail 'cause only the Koreans have it ready. If the IN is fine with paper evaluations, then a shortlist can be done within 6 months after the MoD hands over the tender to the IN.

@_Anonymous_ many years ago, I remember (?) you mentioned that you have inside info on AIP development in India. You also mentioned that there are great people working on it, and that the project is showing great potential to complete successfully.

I guess that was not the case. Not many articles in what went wrong.

Any idea? Is that project shelved?

Nope. You must be mistaking me for someone else. In any case we're nearing 2022. A lot of dynamic developments have been predicted for next year. Both - the expected & the unexpected . Belt your seats up. It's going to be one hell of an exciting roller coaster ride.

The project itself is very much alive as per recent articles . I guess the refit of INS Kalvari is due in 2023 . That's when the AIP goes in & the testing would commence . If everything goes well then by 2027-28 the system itself would be certified for use in the rest of the Kalvari class.
