The 5 Most Lethal Battleships That Never Set Sail
Battleships represented huge, long term investments of national treasure. The took a long time to design, and a long time to construct. In the complex geopolitical and technological environment of the 20th century, battleships planned did not always become battleships built. This article examines five powerful classes of battleships that never saw the sea.
South Dakota (United States):
At the end of World War I, the British, Japanese, and American navies each embarked on an impressive battleship construction spree. The United States, relatively untouched by the war and with the world’s largest economy, was best positioned to win this incipient naval race. The first two American entries were the Lexington class battlecruisers and the South Dakota class battleships.
The U.S. South Dakotas were among the most powerful of these designs. On a relatively modest 48,000 ton displacement, the South Dakotas would have made 23 knots, and carried 12 16” guns in four triple turrets. This main armament would have made them as powerful as any battleships ever constructed. The South Dakotas were designed to serve with the squadron of “standard type” American battleships, although they did enjoy the first increase in speed since 1910.
Fortunately for the taxpayers of the United States, the Washington Naval Treaty intervened. Along with their counterparts in Japan and United Kingdom, the South Dakotas were cancelled. All of the six ships laid down were scrapped before completion.
G3 (United Kingdom):
The G3 class battlecruisers represented a radical departure for the Royal Navy. HMS Hood strongly resembled previous British battlecruisers, although she carried the armor of a battleship. The G3s would adopt several innovations, including the 16” gun, triple turrets, and a modern all-or-nothing protection scheme.
Displacing 48,000 tons, the G3s would have carried 9 16” guns in three triple turrets, with a design speed of 32 knots and armor commensurate to their armament. The G3s were among the ugliest battleships ever conceived, a severe, utilitarian break with the lovely battleships and battlecruisers of the Grand Fleet. Nevertheless, they were superior in armor and armament to the battlecruisers contemplated by Japan and the United Kingdom at the time. Indeed, notwithstanding the fact that they were supposed to enter service in 1925 and 1926, they would have proven competitive with many of the fast battleships that entered service in the 1940s.
As with the South Dakotas and several other battleship classes, the Washington Naval Treaty intervened, and the G3s were never laid down. In the absence of the Treaty, they might have broken the back of the Treasury.
Sovetsky Soyuz (USSR):
In 1918, the Bolshevik regime inherited the Imperial Russian Navy, consisting of a few obsolete dreadnoughts and a host of older, small ships. This flotilla, inadequate to the defense of the USSR’s extensive maritime frontiers, nevertheless served as the core of the new Soviet Navy. During the 1920s and 1930s, Soviet authorities floated various schemes for reconstructing the fleet. The demands of the civil war and the relentlessly hostile international environment meant that Moscow had to delay in favor of other priorities. Moreover, the Soviet economy lacked the strength to withstand a major program of naval construction.
By the late 1930s, however, the USSR was finally prepared to commit to the reconstruction of its battlefleet. Moscow sought warships that could compete with the best that Germany and Japan (then regarded as its two most likely opponents) could offer. The fifteen ships of the Sovetsky Soyuz class would have displaced some 60,000 tons, carrying 9 16” guns in three triple turrets and making 28 knots. They would have provided the core of the four Soviet battle squadrons in the Arctic, the Baltic, the Black Sea, and the Pacific. Unfortunately, design requirements exceeded the capabilities of the Soviet shipbuilding. The Soviets could not manufacture sufficiently thick armor plate, resulting in weakened protection. More importantly, Soviet shipbuilders lacked expertise in such large ships. The Soviets had to cancel one of the ships after the laying of the keel, because the shipbuilders had so botched the job that it could not be repaired.
In any case, the German invasion of 1941 ended Stalin’s dreams of a huge, modern battlefleet. Soviet landpower and airpower would save the Motherland, and the battleships of the Sovetsky Soyuz class would never see service.
As the restrictions imposed on Germany by the Treaty of Versailles crumbled, then collapsed, Hitler sought to rebuild German naval strength. The first step was construction of the two Scharnhorst class battleships, followed by the much larger and more powerful Bismarck and Tirpitz. With lessons learned from those ships, the Germans would begin the real core of the fleet, the six battleships of the H-39 class.
The H39s resembled enlarged Bismarcks, but likely would have benefitted from lessons learned from that class. The H-39s would have displaced 57,000 tons, made 30 knots, and carried 8 16” guns in four twin turrets, a decision designed to ensure an adequate rate of fire. German planners expected to contest not only the North Sea, but also the Baltic, and were paying close attention to the progress of the Sovetsky Soyuz class.
