> The nuclear submarine Kazan and three other Russian naval vessels, including the missile frigate Admiral Gorshkov, an oil tanker and a salvage tug, will dock in the Cuban capital from 12-17 June, Cuba’s ministry of the revolutionary armed forces said in a statement. (Also stated: none of the vessels have any nuclear weapons. Though obviously "nuclear" is prime clickbait, from The Guardian's PoV.) Per Wikipedia, both of the warships have been in commission for less than 6 years. Yet they brought along a salvage tug. And an oil tanker. It sounds like the Russian Navy has limited faith in the reliability of their newer vessels. And either their frigate has extremely limited cruising range, or Russia's popularity is too low for them to refuel in neutral ports.
