Super-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-dreadnought battleship, 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 Anglo–German naval arms race, United Kingdom and Germany. Dreadnought races sprang up around the world, including South American dreadnought race, 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, ...

South American Dreadnought Race
A naval arms race among Argentina, Brazil, and Chile—the ABC countries, wealthiest and most powerful countries in South America—began in the early twentieth century when the Brazilian government ordered three dreadnoughts, formidable battleships whose capabilities far outstripped older vessels in the world's navies. In 1904, the Brazilian legislature allocated substantial funds to improve the country's naval forces. Proponents of this plan believed that they needed a strong navy to become an international power and counter Argentine–Chilean naval arms race, recent expansions of the Argentine and Chilean navies. The revolutionary design of the 1906 British warship prompted the Brazilians to alter these plans and redirect their money into constructing three dreadnoughts. These warships, the most powerful in the world, entered service at a time when dreadnoughts were an important factor in a nation's international prestige and therefore brought global attention to Brazil. ...

Battlecruiser
The battlecruiser (also written as battle cruiser or battle-cruiser) was a type of capital ship of the first half of the 20th century. These were similar in displacement, armament and cost to battleships, but differed in form and balance of attributes. Battlecruisers typically had thinner armour (to a varying degree) and a somewhat lighter main gun battery than contemporary battleships, installed on a longer hull with much higher engine power in order to attain greater speeds. The first battlecruisers were designed in the United Kingdom as a successor to the armoured cruiser, at the same time as that the dreadnought succeeded the pre-dreadnought battleship. The goal of the battlecruiser concept was to outrun any ship with similar armament, and chase down any ship with lesser armament; they were intended to hunt down slower, older armoured cruisers and destroy them with heavy gunfire while avoiding combat with the more powerful but slower battleships. However, as more and more ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barr & Stroud
Barr & Stroud Limited was a pioneering Glasgow optical engineering firm. They played a leading role in developing modern optics, including rangefinders, for the Royal Navy and other branches of British Armed Forces during the 20th century. There was a non-military arm of the company which made medical equipment, like photocoagulators and electronic filters, some of which were used by the BBC. The company and its intellectual property passed through Pilkington group to Thales Optronics. The Barr and Stroud name was sold to an importer of optical equipment, who used the trademarked name for a line of binoculars and similar instruments. History Archibald Barr and William Stroud had been associated from as early as 1888 when the two men were professors of, respectively, engineering and physics at the Yorkshire College (now the University of Leeds). In 1891, they were approached by the Admiralty to submit a design for a short-base rangefinder for trial. By this time, Barr had r ...

Range Finder
A rangefinder (also rangefinding telemeter, depending on the context) is a device used to measure distances to remote objects. Originally optical devices used in surveying, they soon found applications in other fields, such as photography, the military, and space travel. They were especially useful for finding the range of a target, such as in naval gunnery and anti-aircraft artillery. The word ''telemeter'' is derived . Designs The first rangefinder telemeter was invented by James Watt in 1769 and put to use in 1771 in surveying canals. Watt called his instrument a micrometer, a term now used with a different meaning in engineering (the micrometer screw gauge). It consisted of two parallel hairs in the focal plane of a telescope eyepiece crossing an upright hair. At the point to be measured, two sliding targets on a surveyor's rod were adjusted to align with the hairs in the telescope. The distance to the rod could then be determined from the distance between the tar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battle Of The Yellow Sea
The Battle of the Yellow Sea (; ) was a naval battle of the Russo-Japanese War, fought on 10 August 1904. In the Russian Navy, it was referred to as the Battle of 10 August. The battle foiled an attempt by the Russian fleet at Lüshunkou (Port Arthur) to break out and form up with the Vladivostok squadron, forcing them to return to port. Four days later, the Battle off Ulsan similarly ended the Vladivostok group's sortie, forcing both fleets to remain at anchor. Background The Imperial Russian Navy's First Pacific Squadron (Admiral Wilgelm Vitgeft) had been trapped in Lüshunkou (Port Arthur) since the Imperial Japanese Navy blockade began on 8 February 1904 with the Battle of Port Arthur. In July and early August, as the Imperial Japanese Army laid siege to Port Arthur, relations between Vitgeft and the Russian Viceroy Yevgeni Alekseyev soured. Alekseyev, a former admiral, favored an aggressive sortie so as to enable the First Pacific Squadron to link up with the Vladivosto ...

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] |
Naval War College
The Naval War College (NWC or NAVWARCOL) is the staff college and "Home of Thought" for the United States Navy at Naval Station Newport in Newport, Rhode Island. The NWC educates and develops leaders, supports defining the future Navy and associated roles and missions, supports combat readiness, and strengthens global maritime partnerships. The Naval War College is one of the senior service colleges including the United States Army War College, Army War College, the Marine Corps War College, and the USAF Air War College. Additionally, the U.S. Department of Defense operates the National War College. History The college was established on October 6, 1884; its first president, Commodore Stephen Luce, Stephen B. Luce, was given the old building of the Newport Asylum for the Poor to house it on Coasters Harbor Island in Narragansett Bay. Among the first four faculty members were Tasker H. Bliss, a future Army Chief of Staff, James R. Soley, the first civilian faculty member and a f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battle Of Manila Bay
The Battle of Manila Bay (; ), also known as the Battle of Cavite, took place on May 1, 1898, during the Spanish–American War. The American Asiatic Squadron under Commodore George Dewey engaged and destroyed the Spanish Pacific Squadron under ''Contraalmirante'' (Rear admiral) Patricio Montojo. The battle took place in Manila Bay in the Philippines, and was the first major engagement of the Spanish–American War. The battle was one of the most decisive naval battles in history and marked the end of the Spanish colonial period in Philippine history. Tensions between Spain and the United States worsened over the Spanish conduct during their efforts to quell the Cuban War of Independence, with many Americans being agitated by largely falsified reports of Spanish atrocities against the Cuban population. In January 1898, fearing the fate of American interests in Cuba due to the war, the cruiser was dispatched to protect them. Less than a month later, the cruiser explo ...

Mediterranean Fleet
The British Mediterranean Fleet, also known as the Mediterranean Station, was a formation of the Royal Navy. The Fleet was one of the most prestigious commands in the navy for the majority of its history, defending the vital sea link between the United Kingdom and the majority of the British Empire in the Eastern Hemisphere. The first Commander-in-Chief for the Mediterranean Fleet was the appointment of General at Sea Robert Blake in September 1654 (styled as Commander of the Mediterranean Fleet). The Fleet was in existence until 1967. Pre-Second World War The Royal Navy gained a foothold in the Mediterranean Sea when Gibraltar was captured by the British in 1704 during the War of Spanish Succession, and formally allocated to Britain in the 1713 Treaty of Utrecht. Though the British had maintained a naval presence in the Mediterranean before, the capture of Gibraltar allowed the British to establish their first naval base there. The British also used Port Mahon, on the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Torpedo
A modern torpedo is an underwater ranged weapon launched above or below the water surface, self-propelled towards a target, with an explosive warhead designed to detonate either on contact with or in proximity to the target. Historically, such a device was called an automotive, automobile, locomotive, or fish torpedo; colloquially, a ''fish''. The term ''torpedo'' originally applied to a variety of devices, most of which would today be called mines. From about 1900, ''torpedo'' has been used strictly to designate a self-propelled underwater explosive device. While the 19th-century battleship had evolved primarily with a view to engagements between armored warships with large-caliber guns, the invention and refinement of torpedoes from the 1860s onwards allowed small torpedo boats and other lighter surface vessels, submarines/submersibles, even improvised fishing boats or frogmen, and later light aircraft, to destroy large ships without the need of large guns, though somet ...
