Japanese Cruiser Yoshino
was a protected cruiser of the Imperial Japanese Navy. ''Yoshino'' is sometimes regarded as a sister ship to , although the two vessels are of different classes. The name ''Yoshino'' comes from the Yoshino mountains, located in the southern portion of Nara prefecture. She played an important role in the First Sino-Japanese War, but was sunk in the Russo-Japanese War after being rammed by Japanese armored cruiser in dense fog. Background ''Yoshino'' was an improved design of the Argentine Navy cruiser ''Veinticinco de Mayo'' designed by Sir Philip Watts, and built by the Armstrong Whitworth shipyards in Elswick, in the United Kingdom. Watts was also responsible for the design of the cruiser and the s. When commissioned, ''Yoshino'' was the largest ship in the Imperial Japanese Navy, and was also the fastest cruiser in the world when she entered service.Evans, ''Kaigun'', p. 34.Elleman, ''Modern Chinese Warfare'', p. 102.

Pacific War
The Pacific War, sometimes called the Asia–Pacific War, was the theater of World War II that was fought in Asia, the Pacific Ocean, the Indian Ocean, and Oceania. It was geographically the largest theater of the war, including the vast Pacific Ocean theater, the South West Pacific theater, the Second Sino-Japanese War, and the Soviet–Japanese War. The Second Sino-Japanese War between the Empire of Japan and the Republic of China had been in progress since 7 July 1937, with hostilities dating back as far as 19 September 1931 with the Japanese invasion of Manchuria. However, it is more widely accepted that the Pacific War itself began on 7 December (8 December Japanese time) 1941, when the Japanese simultaneously invaded Thailand, attacked the British colonies of Malaya, Singapore, and Hong Kong as well as the United States military and naval bases in Hawaii, Wake Island, Guam, and the Philippines. The Pacific War saw the Allies pitted against Japan, the latter ai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
First Sino-Japanese War
The First Sino-Japanese War (25 July 1894 – 17 April 1895) was a conflict between China and Japan primarily over influence in Korea. After more than six months of unbroken successes by Japanese land and naval forces and the loss of the port of Weihaiwei, the Qing government sued for peace in February 1895. The war demonstrated the failure of the Qing dynasty's attempts to modernize its military and fend off threats to its sovereignty, especially when compared with Japan's successful Meiji Restoration. For the first time, regional dominance in East Asia shifted from China to Japan; the prestige of the Qing dynasty, along with the classical tradition in China, suffered a major blow. The humiliating loss of Korea as a tributary state sparked an unprecedented public outcry. Within China, the defeat was a catalyst for a series of political upheavals led by Sun Yat-sen and Kang Youwei, culminating in the 1911 Xinhai Revolution. The war is commonly known in China as the War of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gun Shield
A U.S. Marine manning an M240 machine gun equipped with a gun shield A gun shield is a flat (or sometimes curved) piece of armor designed to be mounted on a crew-served weapon such as a machine gun, automatic grenade launcher, or artillery piece. Military Some mounted machine guns and artillery pieces are equipped with metal armor plates to protect the gunners from small arms fire and shrapnel from explosions. They were fitted to some armored fighting vehicles and patrol boats during the Vietnam War. Gun shields fell out of widespread use after the Vietnam war, but they have seen a resurgence in popularity during the 1990s. Israeli military analysts began urging the use of gun shields, pointing to the grave risk to soldiers exposed to fire from automatic weapons. In particular, it was noted that many casualties were hit in areas not protected by body armor or a helmet, such as the neck or face. The U.S. began using gun shields during the 2000s-era wars in Iraq and Afghanista ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Main Battery
A main battery is the primary weapon or group of weapons around which a warship is designed. As such, a main battery was historically a gun or group of guns, as in the broadsides of cannon on a ship of the line. Later, this came to be turreted groups of similar large-caliber naval rifles. With the evolution of technology the term has come to encompass guided missiles as a vessel's principal offensive weapon, deployed both on surface ships and submarines. A main battery features common parts, ammunition, and fire control across the weapons which it comprises. Description In the age of cannon at sea, the main battery was the principal group of weapons around which a ship was designed, usually its heavies. With the coming of naval rifles and subsequent revolving gun turrets, the main battery became the principal group of heaviest guns, regardless of how many turrets they were placed in. As missiles displaced guns both above and below the water their principal group became a ve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steam Engine
A steam engine is a heat engine that performs mechanical work using steam as its working fluid. The steam engine uses the force produced by steam pressure to push a piston back and forth inside a cylinder. This pushing force can be transformed, by a connecting rod and crank, into rotational force for work. The term "steam engine" is generally applied only to reciprocating engines as just described, not to the steam turbine. Steam engines are external combustion engines, where the working fluid is separated from the combustion products. The ideal thermodynamic cycle used to analyze this process is called the Rankine cycle. In general usage, the term ''steam engine'' can refer to either complete steam plants (including boilers etc.), such as railway steam locomotives and portable engines, or may refer to the piston or turbine machinery alone, as in the beam engine and stationary steam engine. Although steam-driven devices were known as early as the aeolipile in the f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Naval Ram
A ram was a weapon fitted to varied types of ships, dating back to antiquity. The weapon comprised an underwater prolongation of the bow of the ship to form an armoured beak, usually between 2 and 4 meters (6–12 ft) in length. This would be driven into the hull of an enemy ship to puncture, sink or disable it. Ancient rams It was possibly developed in late Bronze age Egypt, but it only became widely used in later Iron age Mediterranean galleys. The ram was a naval weapon in the Greek/Roman antiquity and was used in such naval battles as Salamis and Actium. Naval warfare in the Mediterranean rarely used sails, and the use of rams specifically required oarsmen rather than sails in order to maneuver with accuracy and speed, and particularly to reverse the movement of a ramming ship to disentangle it from its sinking victim, lest it be pulled down when its victim sank. The Athenians were especially known for their ''diekplous'' and '' periplous'' tactics that disabled enemy ships ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prow
The bow () is the forward part of the hull of a ship or boat, the point that is usually most forward when the vessel is underway. The aft end of the boat is the stern. Prow may be used as a synonym for bow or it may mean the forward-most part of the bow above the waterline. Function A ship's bow should be designed to enable the hull to pass efficiently through the water. Bow shapes vary according to the speed of the boat, the seas or waterways being navigated, and the vessel's function. Where sea conditions are likely to promote pitching, it is useful if the bow provides reserve buoyancy; a flared bow (a raked stem with flared topsides) is ideal to reduce the amount of water shipped over the bow. Ideally, the bow should reduce the resistance and should be tall enough to prevent water from regularly washing over the top of it. Large commercial barges on inland waterways rarely meet big waves and may have remarkably little freeboard at the bow, whereas fast military ve ...

Forecastle
The forecastle ( ; contracted as fo'c'sle or fo'c's'le) is the upper deck of a sailing ship forward of the foremast, or, historically, the forward part of a ship with the sailors' living quarters. Related to the latter meaning is the phrase " before the mast" which denotes anything related to ordinary sailors, as opposed to a ship's officers. History and design In medieval shipbuilding, a ship of war was usually equipped with a tall, multi-deck castle-like structure in the bow of the ship. It served as a platform for archers to shoot down on enemy ships, or as a defensive stronghold if the ship were boarded. A similar but usually much larger structure, called the aftcastle, was at the aft end of the ship, often stretching all the way from the main mast to the stern. Having such tall upper works on the ship was detrimental to sailing performance. As cannons were introduced and gunfire replaced boarding as the primary means of naval combat during the 16th century, the medieval ...

Cruiser
A cruiser is a type of warship. Modern cruisers are generally the largest ships in a fleet after aircraft carriers and amphibious assault ships, and can usually perform several roles. The term "cruiser", which has been in use for several hundred years, has changed its meaning over time. During the Age of Sail, the term ''cruising'' referred to certain kinds of missions—independent scouting, commerce protection, or raiding—fulfilled by frigates or sloops-of-war, which functioned as the ''cruising warships'' of a fleet. In the middle of the 19th century, ''cruiser'' came to be a classification of the ships intended for cruising distant waters, for commerce raiding, and for scouting for the battle fleet. Cruisers came in a wide variety of sizes, from the medium-sized protected cruiser to large armored cruisers that were nearly as big (although not as powerful or as well-armored) as a pre-dreadnought battleship. With the advent of the dreadnought battleship before World W ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elswick, Tyne And Wear
Elswick ( ) is a district and electoral ward of the city and metropolitan borough of Newcastle upon Tyne, England, 1.9 miles west of the city centre, bordering the River Tyne. Historically in Northumberland, Elswick became part of Newcastle upon Tyne in 1835. Elswick is home to the Newcastle Utilita Arena; and Newcastle College, with approximately 45,000 students. History In Roman times the Vallum, a defensive barrier behind Hadrian's Wall, reached its easternmost limit in Elswick. The Wall itself carried on as far as Wallsend. The township of Elswick had originally formed part of the Barony of Bolam and was owned by Tynemouth Priory from 1120-1539, with a fishery present on the site. One of the earliest references to the coal mining industry of the north east occurs in 1330, when it was recorded that the Prior of Tynemouth let a colliery, called Heygrove, at "Elstewyke" for a rent of £5 per year. Elswick Colliery had 3 pits working from 1860 onwards. Elswick was owned by t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

ARA Veinticinco De Mayo (1890)
ARA ''Veinticinco de Mayo'' was a protected cruiser that served in the Argentine Navy between 1891 and 1921. Design ''Veinticinco de Mayo'' was a steam-powered protected cruiser similar to built in the same shipyard for the Royal Italian Navy, but improved and larger. Its steel hull had a ram in the bow, and was protected with an armored deck. Its main battery was two guns, one at the bow and another at the stern, and four 124 mm quick-firing guns per side. The secondary battery had twelve 47 mm and twelve 37mm quick-fire Hotchkiss guns. It had two masts, in its tops were mounted eight Maxim machine guns. It initially mounted three torpedo tubes, later increased to six. It also carried two steam boats with spar torpedoes. History In 1890 the Argentine government led by President Miguel Ángel Juárez Celman decided to purchase a new cruiser due to the dispute with Chile concerning the application of the boundary Treaty of 1881.
