Pre-dreadnought
Pre-dreadnought battleships were sea-going battleships built from the mid- to late- 1880s to the early 1900s. Their designs were conceived before the appearance of in 1906 and their classification as "pre-dreadnought" is retrospectively applied. In their day, they were simply known as "battleships" or else more rank-specific terms such as "first-class battleship" and so forth. The pre-dreadnought battleships were the pre-eminent warships of their time and replaced the ironclad battleships of the 1870s and 1880s. In contrast to the multifarious development of ironclads in preceding decades, the 1890s saw navies worldwide start to build battleships to a common design as dozens of ships essentially followed the design of the Royal Navy's . Built from steel, protected by compound, nickel steel or case-hardened steel armor, pre-dreadnought battleships were driven by coal-fired boilers powering compound reciprocating steam engines which turned underwater screws. These ships dis ...

Battleship
A battleship is a large, heavily naval armour, armored warship with a main battery consisting of large naval gun, guns, designed to serve as a capital ship. From their advent in the late 1880s, battleships were among the largest and most formidable weapon systems ever built, until they were surpassed by aircraft carriers beginning in the 1940s. The modern battleship traces its origin to the sailing ship of the line, which was developed into the steam ship of the line and soon thereafter the ironclad warship. After a period of extensive experimentation in the 1870s and 1880s, ironclad design was largely standardized by the British , which are usually referred to as the first "pre-dreadnought battleships". These ships carried an armament that usually included four large guns and several medium-caliber guns that were to be used against enemy battleships, and numerous small guns for self-defense. Naval powers around the world built dozens of pre-dreadnoughts in the 1890s and early ...

Dreadnought
The dreadnought was the predominant type of battleship in the early 20th century. The first of the kind, the Royal Navy's , had such an effect when launched in 1906 that similar battleships built after her were referred to as "dreadnoughts", and earlier battleships became known as pre-dreadnoughts. Her design had two revolutionary features: an "all-big-gun" armament scheme, with an unprecedented number of heavy-calibre guns, and steam turbine propulsion. As dreadnoughts became a crucial symbol of national power, the arrival of these new warships renewed the naval arms race between the United Kingdom and Germany. Dreadnought races sprang up around the world, including in South America, lasting up to the beginning of World War I. Successive designs increased rapidly in size and made use of improvements in armament, armour, and propulsion throughout the dreadnought era. Within five years, new battleships outclassed ''Dreadnought'' herself. These more powerful vessels were know ...

Imperial Japanese Navy
The Imperial Japanese Navy (IJN; Kyūjitai: Shinjitai: ' 'Navy of the Greater Japanese Empire', or ''Nippon Kaigun'', 'Japanese Navy') was the navy of the Empire of Japan from 1868 to 1945, Potsdam Declaration, when it was dissolved following surrender of Japan, Japan's surrender in World War II. The Japan Maritime Self-Defense Force (JMSDF) was formed between 1952 and 1954 after the dissolution of the IJN. The IJN was the third largest navy in the world by 1920, behind the Royal Navy and the United States Navy (USN). It was supported by the Imperial Japanese Navy Air Service for reconnaissance and airstrike operations from the fleet. It was the primary opponent of the Allies of World War II, Western Allies in the Pacific War. The IJN additionally fielded Imperial Japanese Navy land forces, limited land-based forces, including Special Naval Landing Forces, professional marines, Japanese marine paratroopers of World War II, marine paratrooper units, anti-aircraft defense units ...

Gun Turret
A gun turret (or simply turret) is a mounting platform from which weapons can be fired that affords protection, visibility and ability to turn and aim. A modern gun turret is generally a rotatable weapon mount that houses the crew or mechanism of a projectile-firing weapon and at the same time lets the weapon be aimed and fired in some degree of azimuth and elevation (cone of fire). Description Rotating gun turrets protect the weapon and its crew as they rotate. When this meaning of the word "turret" started being used at the beginning of the 1860s, turrets were normally cylindrical. Barbettes were an alternative to turrets; with a barbette the protection was fixed, and the weapon and crew were on a rotating platform inside the barbette. In the 1890s, armoured hoods (also known as "gun houses") were added to barbettes; these rotated with the platform (hence the term "hooded barbette"). By the early 20th century, these hoods were known as turrets. Modern warships have gun-m ...

Ironclad Warship
An ironclad was a steam-propelled warship protected by steel or iron armor constructed from 1859 to the early 1890s. The ironclad was developed as a result of the vulnerability of wooden warships to explosive or incendiary shells. The first ironclad battleship, , was launched by the French Navy in November 1859, narrowly preempting the British Royal Navy. However, Britain built the first completely iron-hulled warships. Ironclads were first used in warfare in 1862 during the American Civil War, when they operated against wooden ships, and against each other at the Battle of Hampton Roads in Virginia. Their performance demonstrated that the ironclad had replaced the unarmored ship of the line as the most powerful warship afloat. Ironclad gunboats became very successful in the American Civil War. Ironclads were designed for several uses, including as high-seas battleships, long-range cruisers, and coastal defense ships. Rapid development of warship design in the late 19th ...

Secondary Armament
Secondary armaments are smaller, faster-firing weapons that are typically effective at a shorter range than the main battery, main (heavy) weapons on military systems, including battleship- and cruiser-type warships, tanks/armored personnel carriers, and rarely other systems. The nature, disposition, size and purpose of Naval secondary weapon systems changed dramatically as the threat changed from torpedo boats, to torpedo-carrying destroyers, to aircraft, to anti-ship missiles. Naval Pre-dreadnought era Pre-dreadnoughts, from the period 1890 to 1905, were typically fitted with 3 or 4 different calibres of weapon. The main guns were usually approximately 12-inch caliber, secondary weapons usually 6-inch but typically in the range 5-inch to 7.5-inch. Guns smaller than 4.7-inch are usually considered "tertiary". (Many pre-dreadnoughts also carried 9.2 to 10-inch "secondary" guns, but they are usually treated instead as a mixed-caliber main armament.) Secondary guns were ...

Barbette
Barbettes are several types of gun emplacement in terrestrial fortifications or on naval ships. In recent naval usage, a barbette is a protective circular armour support for a heavy gun turret. This evolved from earlier forms of gun protection that eventually led to the pre-dreadnought. The name ''barbette'' ultimately comes from fortification: it originally meant a raised platform or mound, as in the French phrase ''en barbette'', which refers to the practice of firing a cannon over a parapet rather than through an embrasure in a fortification's casemate. The former gives better angles of fire but less protection than the latter. The disappearing gun was a variation on the barbette gun; it consisted of a heavy gun on a carriage that would retract behind a parapet or into a gunpit for reloading. Barbettes were primarily used in coastal defences, but saw some use in a handful of warships, and some inland fortifications. The term is also used for certain aircraft gun mounts. ...

HMS Ocean (Canopus-class Battleship)
Six ships that were built for the Royal Navy have borne the name HMS ''Ocean''. The name ''Ocean'' entered the list from which names are selected for British ships in 1759, when the Royal Navy captured the French ship named . The British studied the French technology of this ship and admired it, but the ship had to be in bad shape before it would be replaced by a new-build. * , was a 90-gun ship of the line built in 1761. * , was a 98-gun ship of the line launched in 1805, active in the Napoleonic Wars, and later upgraded to a 110-gun first-rate. * was originally ordered to be built as a ''Bulwark''-class wooden screw line-of battle ship intended to carry 91 guns. However, the order was changed and she was eventually launched in 1863 as a of 24 guns. In the late 1860s she served as flagship to the Commander-in-Chief, China and after an active life of only six years, was paid off in 1872. * was a ''Canopus''-class pre-dreadnought battleship launched in 1898 and sunk by a mine ...

Battle Of Tsushima
The Battle of Tsushima (, ''Tsusimskoye srazheniye''), also known in Japan as the , was the final naval battle of the Russo-Japanese War, fought on 27–28 May 1905 in the Tsushima Strait. A devastating defeat for the Imperial Russian Navy, the battle was the only Decisive victory, decisive engagement ever fought between modern steel battleship fleets and the first in which wireless telegraphy (radio) played a critically important role. The battle was described by contemporary Sir George Sydenham Clarke, Sir George Clarke as "by far the greatest and the most important naval event since Battle of Trafalgar, Trafalgar". The battle involved the Japanese Combined Fleet under Admiral Tōgō Heihachirō and the Russian Second Pacific Squadron under Admiral Zinovy Rozhestvensky, which had sailed over seven months and from the Baltic Sea. The Russians hoped to reach Vladivostok and establish naval control of the Far East in order to relieve the Imperial Russian Army in Manchuria. The R ...

Imperial Russian Navy
The Imperial Russian Navy () operated as the navy of the Russian Tsardom and later the Russian Empire from 1696 to 1917. Formally established in 1696, it lasted until being dissolved in the wake of the February Revolution and the declaration of the Russian Republic in 1917. It developed from a smaller force that had existed prior to Tsar Peter the Great's founding of the modern Russian navy during the Azov campaigns (1695–1696), Second Azov campaign in 1696, and expanded in the second half of the 18th century before reaching its peak strength by the early part of the 19th century, behind only the British and French fleets in terms of size. The Imperial Navy drew its officers from the aristocracy of the Empire, who belonged to the state Russian Orthodox Church. Young aristocrats began to be trained for leadership at a national naval boarding school, the Naval Cadet Corps (Russia), Naval Cadet Corps. From 1818 on, only officers of the Imperial Russian Navy were appointed to the p ...

French Third Republic
The French Third Republic (, sometimes written as ) was the system of government adopted in France from 4 September 1870, when the Second French Empire collapsed during the Franco-Prussian War, until 10 July 1940, after the Fall of France during World War II led to the formation of the Vichy France, Vichy government. The French Third Republic was a parliamentary republic. The early days of the French Third Republic were dominated by political disruption caused by the Franco-Prussian War of 1870–1871, which the French Third Republic continued to wage after the fall of Emperor Napoleon III in 1870. Social upheaval and the Paris Commune preceded the final defeat. The German Empire, proclaimed by the invaders in Palace of Versailles, annexed the French regions of Alsace (keeping the ) and Lorraine (the northeastern part, i.e. present-day Moselle (department), department of Moselle). The early governments of the French Third Republic considered French Third Restoration, re-establi ...
