The Chinese members here forget of the blood war / conflict the British Empire had with the Russians in the Crimean War. In fact, one of the threats Britain had from Russia was the Russian Baltic Fleet, which occasionally moved from its home base in St. Petersburg to the Black Sea, where it could harass the Royal Navy as well as the French Imperial Navy during the course of the Crimean War.
When Russia's Baltic Fleet (its greatest and largest fleet) was completely and utterly annihilated by the Imperial Navy, the threat of Russian's Imperial Navy was nullified. In fact, from 1905 till the end of the 1950s, Russia ceased to be a Naval Power. And proved no threat to either the Allies, or even the Germans from WW1 to WW2.
