“In the mode of sound underwater communication, a message was transmitted to the crew of a foreign submarine in Russian and English: “You are in the territorial waters of Russia.
Come up immediately!"
The crew of the American submarine ignored the demand of the Russian side,” the Ministry of Defense said.
When the crew of the Pacific Fleet frigate "Marshal Shaposhnikov" used "appropriate means", the American submarine used a self-propelled simulator to split the target on the means of radar and acoustic control.
After that, she "left the territorial waters of the Russian Federation with maximum speed."
On February 12, the Russian Ministry of Defense reported that on February 12, a US Virginia-class submarine was discovered in Russian territorial waters near the Kuril Island Urup.
