US nuclear-powered submarine arrives in Guantanamo Bay a day after Russian Navy docks in Havana

The USS Helena, a fast-attack nuclear submarine, surfaced in Guantanamo Bay, Cuba, a day after Russian naval forces arrived in Havana to conduct drills with the island nation, a Russian ally.

In a statement posted on X, US Southern Command said, “The fast-attack submarine USS Helena is in Guantanamo Bay, Cuba as part of a routine port visit as it transits the U.S. Southern Command geographic area of responsibility while conducting its global maritime security and national defense mission.”

The specific movements of Navy submarines are highly classified and are rarely disclosed publicly.

The Pentagon has reiterated the presence of the Russian flotilla, despite its being 90 miles from the coast of Florida, does not pose a threat to the security of the United States. Navy destroyers, as well as P-8 submarine hunting aircraft, tracked the movements of the Russian ships as they made their way south off the east coast of the United States.
