The US Navy bragged that its destroyer came to "challenge" Moscow in the Sea of Japan, but the ship didn't even come near Russia's territorial waters and was tracked all the way, the Defense Ministry said.
Nor did the Navy leave any ambiguity about why the USS McCampbell made the journey.
"USSMcCampbell sailed in the vicinity of the Peter the Great Gulf, thus challenging the excessive Maritime claims of Russian Federation and defending the rights, freedoms and lawful uses of the sea enjoyed by the U.S. and other States", said Mcmurry. However, Russia claims the entirety of Peter the Great Bay, extending well beyond 12 nautical miles from sections of the coast.
Throughout the sailing, the US warship was escorted and moved under the control of the large anti-submarine ship Admiral Tributs and several warplanes of Russia's Pacific Fleet's naval aviation that were in close proximity, the Russian Ministry of Defence says further.
She said: "These operations demonstrate the United States will fly, sail and operate wherever global law allows".
The last USA ship to enter the Black Sea was the fast transport ship USNS Carson City in October. "That is true in the Sea of Japan, as in other places around the globe", McMarr said. Peter the Great Bay is the largest gulf in the Sea of Japan, also referred to as the East Sea by the Koreas, and home to the Russian's far-east city of Vladivostok and the Russian Navy's Pacific Fleet.
