Once upon a time... (

)
For some strange reason, the navies of the world had continued building wooden ships-of-the-line such as the
HMS Victory (which was simply an improvement upon the revolutionary
Sovereign-of-the-Seas of 1637) up until the mid-19th century. These ships fired round shot albeit the advances in gunnery really should have made them obsolete decades before. They even installed steam engines in these wooden ships!

Then the French built a frigate called
Gloire (1859?) that had her wooden hull plated over with 5" thick iron which made her impervious to every naval gun then in use.
Now followed a period of experimentation that saw battleships of increasingly fantastic designs - central turret battleships, barbette battleships, citadel battleships etc. This included some of the most bizarre ships ever designed such as the completely round Russian "battleship" the
Novgorod or the French
Hoche which, for the comfort lavished upon its officers, was known as "Le Grand Hôtel" and would have capsized if at sea in anything but a flat calm. By the early 1890s, designs had stabilised around a ship with four heavy guns in twin turrets, one fore one aft, plus medium calibre artillery of about a dozen guns in casemates. This type was called line-of-battle ships to differentiate between them and the wooden ship-of-the line. This type of battleship is known today as the pre-Dreadnought battleship.
In 1903, Cuniberti proposed an All-big-gun Battleship for the Royal Navy. The first dreadnoughts designed were the
USS South Carolina-class but the first such completed was
HMS Dreadnought in 1906. The naval race between Great Britain and Germany involved two types of capital ship; the battleship and the much faster but less armoured battle-cruiser. The race culminated with two designs - the British
Queen Elizabeth-class super-dreadnoughts, powerfully armed and armoured with a speed not much inferior to the earlier battle-cruisers, and the German
Mackensen-class battle-cruiser which to all intents and purposes was the fast battleship that the QE-class had not quite managed.
This, in brief, is the history of the development of the modern battleship from the first ironclad to the last behemoths, the
DKM Bismarck, the
IJN Yamato and the
USS Iowa.
