Ships of U.S.S.R
With over half her massive landmass bordered by water, Russia's navy was (and still is today) divided into four major fleets: the Pacific, Northern, Baltic and Black Sea Fleets; at the height of the Russian Empire, the Imperial Russian Navy was the fourth most powerful fleet in the world after Great Britain, Spain and France. Lagging technological advancement and disastrous wars greatly dented her power, resulting in mixed performance in World War I; the Baltic Fleet played a largely defensive role, the Black Sea Fleet distinguished herself against the Ottoman Navy and the Pacific Fleet had faded into insignificance following the Russo-Japanese War and the Battle of Tsushima in 1905. (The Northern Fleet was created during World War I to protect shipping in the Barents Sea.) The Imperial Russian Navy suffered a near-complete collapse in the Russian Revolution and resulting Civil War, and was eventually succeeded by the Soviet Union's Red Fleet.
Russian cruisers are similar to their American and German counterparts — focusing on gunnery — but are more or less the eponymous "jack of all trades" cruisers. From from Tier VI onwards, they mount largely 6-inch (152mm) guns that behave much like the fast-firing guns of the American Tier V cruiser Omaha, but they have more of the Kriegsmarine's flat firing arcs and high shell velocities. Overall their anti-aircraft armament is middle-of-the road, and sufficient primarily for self-defense.
USSR destroyers are well-known for their weak-hitting torpedoes, but this is compensated by their sheer numbers, more than any nation. They behave like their USN counterparts, being great gunboats, they are also firestarters like their IJN cousins. Their weakness is that they are quite slower than their other destroyer counterparts, USSR suffer also from short torpedo ranges, much like their cruiser brethren.
