Empire Of Japan
The also known as the Japanese Empire or Imperial Japan, was a historical nation-state and great power that existed from the Meiji Restoration in 1868 until the enactment of the post-World War II 1947 constitution and subsequent formation of modern Japan. It encompassed the Japanese archipelago and several colonies, protectorates, mandates, and other territories. Under the slogans of and following the Boshin War and restoration of power to the Emperor from the Shogun, Japan underwent a period of industrialization and militarization, the Meiji Restoration, which is often regarded as the fastest modernisation of any country to date. All of these aspects contributed to Japan's emergence as a great power and the establishment of a colonial empire following the First Sino-Japanese War, the Boxer Rebellion, the Russo-Japanese War, and World War I. Economic and political turmoil in the 1920s, including the Great Depression, led to the rise of militarism, nationa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fleet Submarine
A fleet submarine is a submarine with the speed, range, and endurance to operate as part of a navy's battle fleet. Examples of fleet submarines are the British First World War era K class and the American World War II era ''Gato'' class. The term has survived in Britain to refer to modern nuclear-powered attack submarines. In the United States Navy, the term came to be used primarily for the long-range submarines that served in World War II. Examples United States The term was used by the United States Navy to distinguish submarines suitable for long range patrols in the Pacific Ocean from earlier classes such as the United States S-class submarines. The initial goal, pursued with frequent interruptions since the ''AA-1''-class (aka ''T''-class) launched 1918–19, was to produce a submarine with a surfaced speed of 21 knots to operate with the Standard-type battleships of the surface fleet. Most of the nine "V-boats" launched 1924-33 (''V-1'' through ''V-6'') were either a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Combined Fleet
The was the main sea-going component of the Imperial Japanese Navy. Until 1933, the Combined Fleet was not a permanent organization, but a temporary force formed for the duration of a conflict or major naval maneuvers from various units normally under separate commands in peacetime. History Sino-Japanese War (1894–95) The Combined Fleet was formally created for the first time on 18 July 1894 by the merger of the Standing Fleet and the Western Fleet. The Standing Fleet (also known as the Readiness Fleet) contained the navy's most modern and combat-capable warships. The Western Fleet was a reserve force consisting primarily of obsolete ships deemed unsuitable for front-line combat operations, but still suitable for commerce protection and coastal defense. Vice-admiral Itō Sukeyuki was appointed the first Commander-in-Chief of the Combined Fleet for the duration of the first Sino-Japanese War against China. Russo-Japanese War (1904–05) The Combined Fleet was re-formed d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2nd Fleet (Imperial Japanese Navy)
The was a fleet of the Imperial Japanese Navy (IJN) created as a mobile strike force in response to hostilities with Russia, and saw action in every IJN military operation until the end of World War II. History Established on 27 October 1903, the 2nd Fleet was created by the Imperial General Headquarters as a mobile strike force of cruisers and destroyers to pursue the Imperial Russian Navy's Vladivostok-based cruiser squadron while the remaining bulk of the Japanese fleet (the IJN 1st Fleet) continued to blockade Port Arthur in hopes of luring the battleships of the Russian Pacific Fleet into an open sea classic line of battle confrontation. As the main mobile force in the IJN, the 2nd Fleet saw the bulk of all future IJN combat operations from the time of its inception until IJN dissolution at the end of World War II.

Squadron (naval)
A squadron, or naval squadron, is a significant group of warships which is nonetheless considered too small to be designated a fleet. A squadron is typically a part of a fleet. Between different navies there are no clear defining parameters to distinguish a squadron from a fleet (or from a flotilla), and the size and strength of a naval squadron varies greatly according to the country and time period. Groups of small warships, or small groups of major warships, might instead be designated flotillas by some navies according to their terminology. Since the size of a naval squadron varies greatly, the rank associated with command of a squadron also varies greatly. Before 1864 the entire fleet of the Royal Navy was divided into three squadrons, the red, the white, and the blue. Each Royal Navy squadron alone was more powerful than most national navies. Today, a squadron might number three to ten vessels, which might be major warships, transport ships, submarines, or small craft i ...

Flagship
A flagship is a vessel used by the commanding officer of a group of naval ships, characteristically a flag officer entitled by custom to fly a distinguishing flag. Used more loosely, it is the lead ship in a fleet of vessels, typically the first, largest, fastest, most heavily armed, or best known. Over the years, the term "flagship" has become a metaphor used in industries such as broadcasting, automobiles, education, technology, airlines, and retail to refer to their highest profile or most expensive products and locations. Naval use In common naval use, the term ''flagship'' is fundamentally a temporary designation; the flagship is wherever the admiral's flag is being flown. However, admirals have always needed additional facilities, including a meeting room large enough to hold all the captains of the fleet and a place for the admiral's staff to make plans and draw up orders. Historically, only larger ships could accommodate such requirements. The term was also used by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Division (naval)
A naval division is a subdivision of a squadron or flotilla. It can also be a subdivision of a fleet. A division is the smallest naval formation, most commonly numbering between two to four ships. Command element A division is usually commanded by senior flag officer, most commonly a vice admiral or rear admiral, irrespective of the division's size. For example, in the Imperial Japanese Navy the First Carrier Division was commanded by a rear or vice admiral, same as the 18th Cruiser Division. Division types Divisions are most commonly grouped by ship class and type, dependent on how the respective nation's navy is organised. Examples of division types include: *Submarine Division – 24th Submarine Division ( Soviet Navy and Russian Navy) – six submarines *Minesweeper Division – Mine Division 71 (United States Navy) – two minesweepers *Sloop Division – 2nd Escort Group (Royal Navy) – six sloops *Destroyer Division – Destroyer Division 22 (United States Nav ...

Tokuyama, Yamaguchi, Tokuyama port, was also part of Kure Naval District, and had the largest fuel depot in the Japanese Navy. History The location of Kure, Hiroshima, Kure within the sheltered Inland Sea of Japan was recognized of strategic importance in controlling the sea lanes around western Japan by the Meiji government and early Imperial Japanese Navy.

Ship Commissioning
Ship commissioning is the act or ceremony of placing a ship in active service and may be regarded as a particular application of the general concepts and practices of project commissioning. The term is most commonly applied to placing a warship in active duty with its country's military forces. The ceremonies involved are often rooted in centuries-old naval tradition. Ship naming and launching endow a ship hull with her identity, but many milestones remain before she is completed and considered ready to be designated a commissioned ship. The engineering plant, weapon and electronic systems, galley, and other equipment required to transform the new hull into an operating and habitable warship are installed and tested. The prospective commanding officer, ship's officers, the petty officers, and seamen who will form the crew report for training and familiarization with their new ship. Before commissioning, the new ship undergoes sea trials to identify any deficiencies needing corre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
