I doubt France would ever offer us reactor tech, even if our boats were LEU fuelled. But that's not the point.

I'm saying the Suffren design would be off the table as a classified item.

Help with pumpjet propulsion, hydrodynamic model testing, digital modeling of interior machinery and crew spaced is perhaps all that we can hope for + sonar et al.

Given that your next-gen SSBN is an evolution of the Suffren design, France would naturally want to prevent tech leaks to any 3rd parties.
Our SSN needs are for much bigger boats than Suffren class.

Shortfins Barracuda was a direct derivative of Barracuda SSN.
Since Aukus I think the french loose a lot of their virginity....

Even if they offer why the heck would we accept we literally built a massive enrichment facility at Challkere for this reason of NOT using LEU for our nuclear subs.

The Aussies did you dirty. But they are an allied nation, India is not. Different set of rules. Plus they have next to no MIC. So it would've been to your advantage.

Considering NGs rant about TKMS transferring 'too much tech', India would have had to contend with just surface level tech while forking out big money.

I'd rate French sub designs as much better than Russia's (absolutely no comparison when it comes to aesthetics).

But there are other factors at play like our traditional closeness with Russia.

You are wrong about modern Russian submarine design in anyway inferior to suffren. Latest Yasen-M are aesthetically 🔥 & are much more capable than Suffren from weapon load to sensors & probably more quite to. I personally think we should go for a single hull design but with a bigger boat something with a length of a Virginia class or more & pressure hull diameter of a Seawolf.

I kinda like the raked sail design of the French Suffren class better, particularly the leading edge. Very elegant. Probably has some hydrodynamic benefits too.

In terms of brute size and capability though (Zircon, spherical sonar), Yasen-M is the better design though. I'd still say Suffren us the quieter of the two though. Mainly because of the X rudder, pumpjet propulsion.

I'm hoping P77 turns out to be a larger 9,000-10,000t boat with larger VLS, considering it will arrive only in the mid-2030s.

Australia is a kind of new US state. Europe and France specially is moving away of USA.... So for Autralia.

We have absolutely no defense agreement with Australia.

India is a old and trustable partner and a long french weapon customer. Probably a best "friend" than Australia.

The Indian Navy will soon cut INS Khanderi, one of its most modern submarines (it's barely six years old), literally in half, in the Hazira shipyard in Gujarat. And this is because the Pakistan Navy has something India lacks: AIP or air-independent propulsion system. A submarine with an AIP system can be underwater for a fortnight, a huge strategic benefit. Pakistan has three Agosta-class submarines with AIP. India does not have any.

The INS Khanderi will be India's first submarine with AIP; work will begin later this year and is likely to continue for another two years. The AIP will be installed roughly in the middle of the submarine, increasing its size by about 20 metres. It has a length of more than 60 metres and weighs 1,600-1,700 tons. Everyone involved, DRDO (which has built the system), the French designers of the submarine, Mazagon Dock officials, and others, have been consulted and will be involved. After INS Khanderi is ready, the other five French-designed Scorpene class submarines will also be fitted with the AIP system. The six German submarines that India will build will have AIP systems. The issue could be placed before the next Defence Acquisition Council (DAC) meeting, likely later this month.

Meanwhile, the refit of the INS Sindhuvijay, the Russian-built KILO-class submarine, will begin at the Hindustan Shipyard soon. The submarine was commissioned in 1991 and, after the refit, can continue in service for another two decades. Another mid-life update is being readied: the INS Betwa, a 4,000-ton indigenously built frigate. This, too, is about 20 years old, and the DAC may clear it at the next meeting.

More Scorpenes on hold​

India's plan to build three more French-designed Scorpene submarines is now on hold. When French President Emmanuel Macron was here to meet Prime Minister Narendra Modi, he raised the issue in the meetings, and India's response was "We'll look into it." India had provisionally accepted the offer of three Scorpenes, but after a relook, has accepted the German submarine deal, valued at 9 billion euros. The 30 billion-euro deal for 114 Rafales is on, as is the one for the Safran engines. Highly placed officials confirmed that the French raised the issue. The Indian response was a statement about a future review.

Disappointing to hear about cancellation of 3 additional scorpenes. What was the point of wasting everyone's time in developing and negotiating a bid?
