I mentioned a similar idea, a slightly larger then Rubis option; 4000 tons SSN, centered around the one of the two reactors (70-80 mw) from the Type 093B, in an earlier thread. A reactor of at least this power in proportion to this weight would necessary to be able to efficiently add a pump jet, which would really help keep noise levels lower than otherwise.
Btw, the French Rubis was a very noise sub.
The limitation would be weapons carriage and risk of it being a noisy boat, with limited space to silence the subs. If silencing tech can be made enough to fit in a 4000 ton sub, and keep noise levels under 90-95 db, it’s a feasible option. But the type 093B is probably the best design for the PN.
A tested design, with room for missile tubes.
The PN just needs the missile tubes upgraded, to the new large tubes with smaller missiles inside, like China plans for the Type 095. In this way, the enemy won’t know if it’s a SSN or a SSBN.

I would hope we can get the 4000 ton SSN working in the required noise levels because we will have at least a dozen Indian SSNs and SSBNs to keep track of.
Although, China can build 2-3 Type 093B a year. A fleet of 4 Type 093B would be ideal for the PN, if equipped with the large VLS tubes. Enough to keep at least two in second strike configuration and the other two in SSN configuration. Enough to keep at least one of each out on patrol if we really manage our resources. A fleet of 6 would be even better.
The YJ-21: with a 1500 km range a hypersonic glider warhead, better able to evade enemy defenses, could be a decent initial second strike missile. But to say we should rely on SLCM indefinitely is shortsighted, IMHO. enemy defense will only get better and we need the means to cover at least 2000-2500 km, in the performance range of the JL-1A or Pukguksong-3, both about 1.4 meters in diameter. This missile could also be a good follow-on for the ground based missile forces Shaheen 2/3 series of missiles.
Future of India's SSBN fleet
India is situated in a difficult weapons of mass destruction (WMD) region. The fact that both of its nuclear-capable neighbours—China and Pakistan—are engaged in a secret and extensive nuclear cooperation framework adds to New Delhi’s difficulties. Therefore, to create a robust nuclear...

US underestimates the performance of the Type 093 though.
Here are some technical estimates on their part on the latest Chinese SSN tech.
Btw, you can see this concept of the three or four missiles per large vls in the design (similar to the three missile per vls on the Indian arihant) of the Russian Yasen class in the following video and that all future Russian SSNs will be SSGNs.

I would also hope the PN goes for a sub that has a very deep diving capability. India’s Seahawks helicopters dipping sonar can go down to 350 meters, in the 8-11 kHz frequency range and can see between 30-40 km. Similar to what is available from Turkish industry.
The Type 093B is said to be able to go to a depth of 450 meters and the newest Russian subs can go down to 600 meters.
