As far as Russian warships and their capabilities in anti-ship warfare are concerned, Russian ships have realistically gone ahead.
The Russian Navy has more on its plate than just trying to face off with HATO and not every ship they build and put into service needs to be able to take on a US carrier battle group on its own.
Having dozens of launch tubes for million dollar missiles makes little sense if you don't need that capacity all the time.
The UKSK launch tubes are good because they can take a variety of missiles including land attack missiles and also anti ship but also anti sub weapons as well.
Although the small missile ships of projects 21631 and 22800 have a small displacement, the possibility of accommodating 8 anti-ship missiles 3M54 "Kalibr" or Onyx, and maybe in the future also Zircon, gives these ships significantly better capabilities in anti-ship combat compared to Soviet projects, with the exception of cruisers. Although even those missiles on cruisers are not technologically at the level of newer missiles.
The fact that new small ships have potent weapon load potential that even compares with Soviet battle cruisers suggests they are not doing too bad, for many patrol duties all this excess fire power is not going to be needed, but a critical factor is that even the new small boats are fully multirole.
In the past only Cruisers had weapons for most jobs... the primary weapons of the Udaloy Destroyers and the Sovremmeny Destroyers were intended as single role weapons... the anti sub missiles of the Udaloy could be used against ships as a very secondary role but the Udaloy was optimised to hunt subs from its propulsion to its sensors and its weapon fit while the Sovremmeny was optimised for hunting enemy ships with its Sunburn missiles and guns to its propulsion system... 8 anti sub or 8 anti ship missiles on each and each was considered well armed.
These new Corvettes with 8 launch tubes that can take anti sub or anti ship or even precision guided land attack missiles that no previous Soviet ship or sub had the capacity to use, or a mix of different types.
The brand new guns are impressive, the new missiles are active radar homing new generation missiles that are very effective and the land based models have been tested in Ukraine.
However, ONLY two projects have universality, namely project 20380 corvettes (20385 is an even better solution) and project 22350 frigates.
All their new ships will get UKSK launchers and I suspect when the new small short range cheap SAMs are developed... the 10-20kg missiles intended to be carried and used in enormous numbers even their smallest ships will be well defended... with modern AESA radars being more widely deployed and production as it increases will get cheaper so they will start to fit them to everything... that level of radar coverage and precision will make command guided missiles one of the most effective defences for the navy because command guided is super cheap... no expensive sensors in the missiles to be destroyed with each use... the TOR and Tunguska/Pantsir use command guided missiles very very effectively and the missiles are very cheap and deadly accurate.
They don't need every ship to be an AEGIS class cruiser, there are lots of naval duties that wont even require such levels of missiles and sensors, but even their smallest ships will have modern capable systems and equipment.
The Caspian Sea and Black Sea and Baltic Sea don't need super ships, though the Black Sea will need ships that often go to Africa and further afield just like the ships of the Pacific and Northern Fleets will too because the Russian Navy and the Russian merchant marine is what is going to connect Russia to the rest of the world and generate income and growth and development.
Why is the west shooting itself in the foot with sanctions on Russia?
Because Russia is growing and developing... new roads and new rail links and new air ports even new Space Ports... there is money to be made in Russia and the western companies that went there knew that and were making good money till their own governments kicked them out and now Russians or Turks or Chinese or Indians are going to fill the gap and make that money instead... and this will be replicated in every country in Asia and Africa and Central and South America because there is more money in developing and growing a country than there is in destroying it... something the west has forgotten.
As for the 152 caliber gun, it is not impossible that the Koalitsiya-M (M for SEA or MORE in Russian) variant will appear. The current Koalitsiya-SV carries the suffix SV which stands for "land army".
A naval official has stated that the 152mm gun will be used by the Navy... now they weren't specific and didn't mention if it was just going to replace the 130mm Bereg Coastal Gun system or if it would also be fitted to new Destroyers and new Cruisers, but the new 130mm gun they have developed is a single barrel gun, and while it has a decent rate of fire and is a fraction of the weight of the old twin gun system, it simply wont have the sustained fire performance of the old gun.
You don't generally use Frigates or Corvettes for fire support of landings, a Destroyer at the very least or a Cruiser would offer more sustained support because it would carry rather more ready to fire shells.
The 130mm is not a bad gun but the 152mm Coalition beats it in every department by a very wide margin already and they plan to extend the shooting range to over 150km... I seem to remember 170 to 180km figures being mentioned, which is significantly better than the over 25km range of the 130mm guns and likely with a much heavier shell.
The current Coalition has a shell with a range of 70km that uses guidance built in to the fuse system, so further improvements in range should benefit the Navy as well as the Army... and I would think the success of artillery on the battlefield in the Ukraine might make the idea of a 203mm gun suddenly become interesting because that would take the 50kg shell weight up to 110kg shell weight, which makes the range of effects you can get from the round more interesting... at 203mm you could probably develop jamming and exotic rounds like EMP... or guided missile that packs a real punch... you could create a shell of 203mm calibre that has a very long focus HEAT warhead that detonates 30m away from an armoured target with the plasma jet focused to form a thin beam of vapourised metal liner that could penetrate enormous amounts of armour at speeds that will blow past any APS system that does not reach out to 30m.
You could even load a ground mobile drone carrying jammers that moves to make it difficult to deal with... or one that carries multiple independent mini suicide drones...
The potential is enormous.
