Line Drawing of the German H-39 Class Battleship
Friends of Padre Steve’s World,
I am still on Trump and COVID19 overload so I am going back to the introductory article of a series I planned years ago.
This is the introductory article for a series of ten articles on the classes of battleships built or planned by the major powers following the expiration of the Second London Naval Treaty. A previous series of articles dealt with the battleships constructed in compliance or close compliance with the treaty. This series will cover the Japanese Yamato Class, and Super Yamato Class, the British Lion Class, the Vanguard, the German Bismarck and H39 Classes, the French Alsace Class, the Soviet Sovyetskiy Soyuz Class, and finally the American Iowa and Montana classes.
When I first wrote this article over a decade ago I classed all of these ships as post-Treaty designs while overlooking the fact that most were designed during the Treaty period, and that most were designed and built in violation of it, or by invoking the escalator clause. In truth only the Vanguard, the Montana’s and the never laid down German ships of the H-41 Class and beyond, as well as the Japanese Super Yamatos.
All of these ships were designed and built or designed in the late 1930s and early 1940s and with the exception of the Sovietetskiy Soyuz Class built on each navy’s past experience in battleship design and construction. The Japanese had constructed no treaty battleships in the 1930s, so the Yamato’s were the first battleships constructed by Japan since the Nagato Class which had been completed in the 1920s and the incomplete Tosa Class.
The Second London Naval Treaty of 25 March 1936 was signed by France, Britain and the United States. Japan walked out on the conference and the Italians did not sign because of the outcry that their invasion of Abyssinia had evoked. The treaty called for ships to have a standard displacement of not more than 35,000 tons and main armament not to exceed 14” guns. This was a reduction in the size of armament from the previous London and Washington treaties. When the Japanese delayed and then refused to sign the agreement, as did the Italians, refused the United States invoked the escalator clause which permitted them to disregard the treaty limitations.
USS Iowa lead ship of the Iowa class
The Americans who invoked only the armament part of the clause on the North Carolina and South Dakota classes. However they took full advantage of it to construct the 45,000 ton Iowa class. The plans called for six of this class, but only four were completed. The Montana Class of 65,000 tons mounting twelve 16” guns and Provided protection against that type of shell. The Montana Class ships were never laid down but because of their features will be covered in this series of articles.
Line Drawing of the Lion Class
Following the King George V Class the Royal Navy planned the Lion Class which was in essence an enlargement of the King George V Class armed with nine 16” guns. Four of the Lion ships we’re planned, but none were to built. They cancelled early in the war and only one further battleship the 44.500 ton HMS Vanguard would be completed by the Royal Navy but not until 1946.
The Germans, who were not a signatory to the treaty but had an agreement with Britain to limit their total naval tonnage to 35% of Britain’s had build the Scharnhorst Class Battlecruisers in the mid 1930s and began the Bismarck Classthe largest capital ships completed in Europe. These were to be followed by the H39, H41, H42, H43 and H44 classes ranging in displacement from 56,444 tons to 131,000 tons with armament ranging from eight 16” to eight 20” guns. Since just two of the H39’s were laid down and then cancelled while in the early stages of construction, and the others never laid down, so I will only discuss the H39 class in this series. The others only existed in the world of a mad dictator’s fantasies.
The Soviet Union which was never a signatory to any of the naval treaties and had not built a battleship since the First World War planned the massive Sovyetskiy Soyuz Class. This would have been a Class of 15 ships would have displaced 58,220 tons and mounted nine 16” guns. Several designs were evaluated, including those of American and Italian shipbuilders and designers. The foreign designs were rejected in favor of a Soviet design. However, the timing coincided with Stalin’s purge of the Armed forces leadership, as well as men who ran military and naval production plants. This added a further delay in their design and construction. The four initial ships of the class were laid down but never completed due to the Nazi invasion in 1941. Construction was halted and all were scrapped after the war.
The Japanese Yamato Class, the largest battleships ever constructed of 69,998 tons standard displacement armed with nine 18” guns, the largest main battery ever installed on battleships were the largest capital ships built before the second generation of U.S. Navy super carriers.
The French Alsace Class was intended to counter the German H-39s. They would have been an enlarged and more heavily armed modification of the Richelieu Class. However, the German attack and and conquest of France led to their cancellation before they were ever laid down.
The first article I write will be about the Bismarck Class and that will appear later this week. This will be cutting it close because I plan on dealing with Operation Rheinübung, the deployment of Bismarck and Prinz Eugen which would turn out to be one of the most intense times of the war, especially for the British and the Royal Navy. So tomorrow on to the Bismarck and Tirpitz.

I am more into airplanes, but I find all this very instructive.
