The idea of the submarine being an all round capital ship that can replace major surface combatants except maybe aircraft carriers has taken quite a hammering indeed in the current conflict. SSNs & SSGNs just can't project power and hold territory the way that cruisers, battlecruisers, and battleships can, much less give robust support to land forces. Aircraft carriers may be having their own concurrent Götterdämmerung, for a lot of the same reasons.
The war in Ukraine, more precisely the skirmishes in the Black Sea (not even the appropriate term but I can't think about anything better tbh) obviously don't lend themselves to the powerful submarine components deployed by the Russian Navy. Mostly found in the Northern and Pacific Fleet anyway. The Black Sea theater is more suited for USVs, Corvettes, patrol boats and the likes. These large submarines would be of questionable usefulness, yes but that applies to large surface combatants and flat tops as well which would be cumbersome targets for USVs and missiles in a confined space.
The Russian Navy has the goal of controlling the sea lanes important to Russian trade and to cripple the US Navy in a conflict. And crippling the USN is done much more effectively by capable and numerous submarines than by surface combatants. It's just an assumption on my part here, maybe someone who served in the USN can give some insight, but I'd believe a US Navy sailor would be more anxious facing up against a Yasen or Akula SSN than against Gorshkov or even Admiral Nakhimov. Crippling the USN, their supply lines, the American shipping lanes is just much more important to the Russian concept of a war against the US and submarines are just the more suitable tool. Which is why I said it's rightfully deserved that they receive special attention as they're the most capable and important assets of the Russian Navy. Their Yasen-Ms, their Borei-As, Belgorod, the Khabarovsk etc. are the absolute crown jewels in their entire naval history up to this point.
And while something like Kuznetsov could have projected power in theory, we know how that would have looked in practice. And while an SSGN can't do that, it's presumed presence somewhere creates a landscape of caution for the other side.
It may be the German in me speaking, but I truly believe that submarines are just that more useful when shit hits the fan. So while this is all off topic with regards to Nakhimov, the submarine faction in the Russian Navy has all the reasons to be influential.
This makes the re-entry into service of Admiral Nakhimov all the more impressive though.
