MOSCOW, February 12. /TASS/. Russia’s Defense Ministry has summoned a US military attache over the incident with Virginia-class US nuclear-powered submarine detected on Saturday morning near the Pacific Fleet’s drills near Urup Island of the Kuril Chain.

"The attache for defense issues at the US Embassy in Moscow has been summoned to the Russian Defense Ministry in connection with the violation of the Russian state border by the US Navy’s submarine," the ministry said in a statement.

According to the ministry, a Virginia-class submarine belonging to the US Navy was detected on February 12, 2022 at 10.40 (Moscow Time).

Under the guiding documents on protection of the Russian state border in the underwater environment, the crew of the Pacific Fleet’s frigate Marshal Shaposhnikov used appropriate means. The US submarine started a self-propelled simulator to split the target image on radar and acoustic control means into two parts and retreated from Russian territorial waters at a maximum speed, the ministry said.

The Pacific Fleet’s ships continue scheduled drills, including to ensure control in the underwater environment and thwart violations of Russia’s state border.
