They have some corvettes with armament levels comparable to cold war Soviet destroyers, but obviously smaller and lacking endurance to do what bigger ships actually do.
The designs are modular so the bits are now working... it is just a question of designing and building bigger vessels that will have more modular bits on platforms that can operate globally without land based air support.
They have effectively created an AEGIS system that works on all their ships, subs, aircraft, and satellites to share information across platforms which is an enormous step forward many navies have yet to take.
What Russia needs to do now politically is look to the rest of the world and develop trade ties on equal terms and both help the world grow and develop and grow and develop on with them... different to the western model where they ripped off the third world and tried to keep them in their place while exploiting their resources to become rich itself.
They wont have new really big ships for more than a decade, but the ones they have will be more than enough for what they need them for with fairly minor upgrades and improvements.
