– USNI Blog – Russia has been carefully observing the activities of the U.S and British navies in the Black Sea region. It protested through diplomatic channels that the main thrust of Sea Breeze 2018, a Black Sea exercise with Ukraine, was anti-Russian. And according to the Russian Institute of Strategic Research, it was not a coincidence when after Sea Breeze 2017, the United States revealed plans to build a maritime operations center in Ochakiv, a small city located between Crimea and Odessa at the mouth of the Dnieper River.
