Pre-dreadnought Battleship
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 warship, 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 armour, compound, nickel steel or case-hardening, case-hardened steel armor, pre-dreadnought battleships were driven by coal-fired boilers powering triple-expansion steam engine, compou ...

Kingdom Of Italy
The Kingdom of Italy (, ) was a unitary state that existed from 17 March 1861, when Victor Emmanuel II of Kingdom of Sardinia, Sardinia was proclamation of the Kingdom of Italy, proclaimed King of Italy, until 10 June 1946, when the monarchy was abolished, following civil discontent that led to an 1946 Italian institutional referendum, institutional referendum on 2 June 1946. This resulted in a modern Italian Republic. The kingdom was established through the unification of several states over a decades-long process, called the . That process was influenced by the House of Savoy, Savoy-led Kingdom of Sardinia (1720–1861), Kingdom of Sardinia, which was one of Italy's legal Succession of states, predecessor states.

French Ironclad Gloire
The French ironclad ''Gloire'' (, "Glory") was the first ocean-going ironclad, launched in 1859. She was developed after the Crimean War,The Battle of Sinop at the start of the war convinced the world's naval powers that wooden warships could not withstand the new weapons. in response to new developments of naval gun technology, especially the Paixhans guns and rifled guns, which used explosive shells with increased destructive power against wooden ships. Her design was also influenced by the Anglo-French development of ironclad floating batteries to bombard Russian forts during the same war. Design and description ''Gloire'' was designed by the French naval architect Henri Dupuy de Lôme as a 5,630-ton broadside ironclad with a wooden hull. Her 12 cm-thick (4.7 in) armour plates, backed with 43 cm (17 in) of timber, resisted hits by the experimental shooting of the strongest guns of the time (the French 50-pounder and the British 68-pounder) at full ...

Keel Laying
Laying the keel or laying down is the formal recognition of the start of a shipbuilding, ship's construction. It is often marked with a ceremony attended by dignitaries from the shipbuilding company and the ultimate owners of the ship. Keel laying is one of the four specially celebrated events in a ship's life; the others are Ceremonial ship launching, launching, Ship commissioning, commissioning, and Ship decommissioning, decommissioning. Earlier, the event recognized as the keel laying was the initial placement of the central timber making up the backbone of a vessel, called the keel. As steel ships replaced wooden ones, the central timber gave way to a central steel beam. Modern ships are most commonly built in a series of pre-fabricated, complete hull sections rather than around a single keel. The event recognized as the keel laying is the first joining of modular components, or the lowering of the first module into place in the building dock. It is now often called "keel ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steam Turbine
A steam turbine or steam turbine engine is a machine or heat engine that extracts thermal energy from pressurized steam and uses it to do mechanical work utilising a rotating output shaft. Its modern manifestation was invented by Sir Charles Parsons in 1884. It revolutionized marine propulsion and navigation to a significant extent. Fabrication of a modern steam turbine involves advanced metalwork to form high-grade steel alloys into precision parts using technologies that first became available in the 20th century; continued advances in durability and efficiency of steam turbines remains central to the energy economics of the 21st century. The largest steam turbine ever built is the 1,770 MW Arabelle steam turbine built by Arabelle Solutions (previously GE Steam Power), two units of which will be installed at Hinkley Point C Nuclear Power Station, England. The steam turbine is a form of heat engine that derives much of its improvement in thermodynamic efficiency from the u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BL 12 Inch Mk X Naval Gun
The BL 12 inch Gun Mark XMark X = Mark 10. Succeeding versions were Mark XI (11) and XII (12). Britain used Roman numerals to denote Marks (models) of ordnance until after World War II was a British Caliber (artillery), 45-calibre naval artillery, naval gun which was mounted as primary armament on battleships and battlecruisers from 1906. It first appeared on . History The Mk X continued the trend of lengthening gun barrels as far as new construction methods would permit, in order to allow more cordite propellant to be used to attain higher projectile velocities. The Mk X increased the bore length from the BL 12-inch Mk IX naval gun, Mk IX's , increasing muzzle velocity from . Subsequent British attempts to further increase the power of 12-inch guns led to failure with the 50-calibre BL 12-inch Mk XI–XII naval gun, Mk XI and Mk XII guns; the Mk X was the last successful 12-inch British gun. Naval use Mk X guns were mounted in the following ships which served throug ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...
