Russia is “gnashing its teeth” at the US. En route to Cuba, a frigate and a nuclear-powered submarine of the Russian Navy conducted exercises in the Atlantic Ocean that included missile tests, the Defense Ministry in Moscow said on Tuesday, posting a Cold War video.

The gymnasiums in which the nuclear-powered submarine “Kazan” and the frigate “Admiral Garskov” participated involved firing high-precision missiles against virtual targets at a distance of more than 600 kilometers, according to the information from the Russian Ministry of Defense. It was preceded by operational training on the frigate “Admiral Garskov” to repel an air attack.

The nuclear-powered submarine “Kazan” and the frigate “Admiral Garskov” belong to the Russian Navy arriving tomorrow, Wednesday, in Cuba.

Last week, Havana announced that Russian warships they don’t carry nuclear weapons and are not a threat to the area.

Washington is watching carefully the movements of Russian naval power in Cuba, as tension between the US and Russia has increased following the Russian invasion of Ukraine.

The frigate “Admiral Garskov” has been used for tests supersonic rockets Zircon, while he participated last year in naval high schools with warships of China and South Africa.
