That becomes moot when it’s war, and the coverage in question is about the internal political situation of the people they are currently fighting. The same applies to any country at war, and their domestic press coverage of their opposing force, or country.
Because of Russia’s vast geography and relatively limited waterway access, it’s better to think of their different fleets almost as individual smaller navies.
Especially in the context of the Black Sea fleet and Turkey’s ability to restrict access of military vessels through Bosporus and Dardanelles Straits because of the Montreux Convention.
So to answer your question under that more narrow scope, I believe it’s roughly 20% of the Black Sea fleet has been destroyed.
