The task of Russian navy was to invade Odessa and sabotage Ukrainian grain trade. They didn't even attempt Odessa desant, because they knew it was futaile. And they failed at sabotaging Ukrainian grain trade, but not for a lack of effort.

Otherwise these ships served as missile lunchers, but even then they had to widraw to ports far away from Ukraine, because of drone attacks.

Ukraine won the naval battle at tiny fraction of the Russian navy cost.
