Muroto-class Collier
The were a class of collier of the Imperial Japanese Navy (IJN), serving from roughly the end of World War I into World War II. Two vessels were built in 1918-19 under the Eight-eight fleet, Eight-four fleet plan. Background * In 1917, World War I was stagnant. The lengthy war led to an increase in shipping and a shortage of merchant ships. * The IJN utilized steamship companies to perform coal transportation duties. However, this expedient was very costly. The IJN decided to build new colliers under the Eight-four fleet plan. * Their design was ordinary, because the IJN did not impose any special requirements on them. Service * In the 1920s, they engaged in coal transportation duties. * In February 1932, the ''Muroto'' was remodeled, becoming an auxiliary hospital ship. She was refitted as a supply ship in 1941. * In World War II, the value of coal as fuel fell. The ships engaged in transporting goods and troops.

Collier (ship Type)
A collier is a bulk cargo ship designed or used to carry coal. Early evidence of coal being transported by sea includes use of coal in London in 1306. In the fourteenth and fifteenth centuries, coal was shipped from the River Tyne to London and other destinations. Other ports also exported coal for instance the Old Quay in Whitehaven harbour was built in 1634 for the loading of coal. London became highly reliant on the delivery of coal by sea Samuel Pepys expressed concern in the winter of 166667 that war with the Dutch would prevent a fleet of 200 colliers getting through. In 1795, 4,395 cargoes of coal were delivered to London. By 1824, this number had risen to about 7,000; by 1839, it was over 9,000. The trade continued to the end of the twentieth century, with the last cargo of coal leaving the Port of Tyne in February, 2021. The earliest type of collier on which there is detailed information is the Whitby-built ''cat''. These were bluff-bowed, round-sterned, strongly-bui ...

Caliber
In guns, particularly firearms, caliber (or calibre; sometimes abbreviated as "cal") is the specified nominal internal diameter of the gun barrel Gauge (firearms) , bore – regardless of how or where the bore is measured and whether the finished bore matches that specification. It is measured in inches or in millimetres, millimeters. In the United States it is expressed in hundredths of an inch; in the United Kingdom in thousandths; and elsewhere in millimeters. For example, a "45 caliber" firearm has a barrel diameter of roughly . Barrel diameters can also be expressed using metric dimensions. For example, a "9 mm pistol" has a barrel diameter of about 9 millimeters. Since metric and US customary units do not convert evenly at this scale, metric conversions of caliber measured in decimal inches are typically approximations of the precise specifications in non-metric units, and vice versa. In a rifling , rifled barrel, the distance is measured between opposing Rifling#C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
8 Cm/40 3rd Year Type Naval Gun
The Type 41 naval gun otherwise known as the 8 cm/40 3rd Year Type naval gun was a Japanese dual-purpose gun introduced before World War I. Although designated as , its shells were in diameter. Design The Japanese Type 41 naval gun otherwise known as the 8 cm/40 3rd Year Type naval gun was a direct copy of the English QF 12-pounder 12 cwt naval gun. The original 12-pounders were built-up guns with a single-motion interrupted screw breech that fired Fixed Quick Fire ammunition and had bottom mounted hydro-pneumatic recoil systems. Many were mounted on low-angle pedestal mounts in casemates as the standard anti-torpedo boat gun on Japanese warships built between 1890 and 1920. Later guns changed to an autofretted monoblock barrel, taller pedestal mount for increased angles of elevation -5° to +75°, top mounted recoil system, and 45° sliding block breech. The guns fired a high-explosive projectile. After 1915 the guns were mounted on high/low angle m ... [...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, when it was dissolved following Japan's surrender in World War II. The Japan Maritime Self-Defense Force (JMSDF) was formed between 1952–1954 after the dissolution of the IJN. The Imperial Japanese Navy 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 aircraft and airstrike operation from the fleet. It was the primary opponent of the Western Allies in the Pacific War. The origins of the Imperial Japanese Navy go back to early interactions with nations on the Asian continent, beginning in the early medieval period and reaching a peak of activity during the 16th and 17th centuries at a time of cultural exchange with European powers during the Age of Discovery.

World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Archduke Franz Ferdin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eight-eight Fleet
The was a Japanese naval strategy formulated for the development of the Imperial Japanese Navy in the first quarter of the 20th century, which stipulated that the navy should include eight first-class battleships and eight armoured cruisers or battlecruisers. History and development The concept of the "Eight-Eight Fleet" originated in the aftermath of the Russo-Japanese War with the 1907 Imperial Defense Policy between the Japanese government and the competing services of the Army and Navy. The policy called for the construction of a battle fleet of eight modern battleships of 20,000 tons each and eight modern armored cruisers of 18,000 tons each. These were to be complemented by the construction of several lesser warship types, including cruisers and destroyers. The plan was inspired by the Mahanian doctrine of Satō Tetsutarō who advocated that Japanese security could only be guaranteed by a strong navy. Satō argued that to ensure security, Japan should be capable of defea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Battle Of The Bismarck Sea
The Battle of the Bismarck Sea (2–4 March 1943) took place in the South West Pacific Area (SWPA) during World War II when aircraft of the U.S. Fifth Air Force and the Royal Australian Air Force (RAAF) attacked a Japanese convoy carrying troops to Lae, New Guinea. Most of the Japanese task force was destroyed, and Japanese troop losses were heavy. The Japanese convoy was a result of a Japanese Imperial General Headquarters decision in December 1942 to reinforce their position in the South West Pacific. A plan was devised to move some 6,900 troops from Rabaul directly to Lae. The plan was understood to be risky, because Allied air power in the area was strong, but it was decided to proceed because otherwise the troops would have to be landed a considerable distance away and march through inhospitable swamp, mountain and jungle terrain without roads before reaching their destination. On 28 February 1943, the convoy – comprising eight destroyers and eight troop transports with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Meiji Period
The is an era of Japanese history that extended from October 23, 1868 to July 30, 1912. The Meiji era was the first half of the Empire of Japan, when the Japanese people moved from being an isolated feudal society at risk of colonization by Western powers to the new paradigm of a modern, industrialized nation state and emergent great power, influenced by Western scientific, technological, philosophical, political, legal, and aesthetic ideas. As a result of such wholesale adoption of radically different ideas, the changes to Japan were profound, and affected its social structure, internal politics, economy, military, and foreign relations. The period corresponded to the reign of Emperor Meiji. It was preceded by the Keiō era and was succeeded by the Taishō era, upon the accession of Emperor Taishō. The rapid modernization during the Meiji era was not without its opponents, as the rapid changes to society caused many disaffected traditionalists from the former samurai ...
