Japanese Minelayer Shirataka
was a medium-sized minelayer of the Imperial Japanese Navy, which was in service during the Second Sino-Japanese War and World War II. She was the world's first purpose-built anti-submarine netlayer. Also, unlike any other warship in the Japanese Navy, she had two chrysanthemum crests due to her unusual bow configuration. Background Under the fiscal 1923 budget, the Imperial Japanese Navy authorized a new type of minelayer (Project H2) to supplement its aging minelayers, the former cruisers and . The new vessel was designed to carry either 100 Type 5 naval mines, or to function as a netlayer based on design features developed through operational experience to counter German submarines gained in World War I. At first the project plans called for ''Shirataka'' to be a 5,000-ton dedicated netlayer, and to be paired with a 3,000-ton-class minelayer (project number H1, later called ). However, due to budgetary limitations and in response to the Washington Naval Treaty of 1922, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Bow (ship)
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 ...

IJN 3rd Fleet
The was a fleet of the Imperial Japanese Navy (IJN), which was created, and subsequently disbanded on six separate occasions and revived on five separate occasions. =History= Russo-Japanese War First established on 28 December 1903, the 3rd Fleet was created by the Imperial General Headquarters as an administrative unit to manage vessels considered obsolete for front-line combat service. These vessels were used primarily for training and for coastal patrol duties. The 3rd Fleet came under the aegis of the Combined Fleet for the duration of the Russo-Japanese War from March 1904. Although initially derided as a "dinosaur fleet", the 3rd fleet proved invaluable at the Battle of Tsushima and the Invasion of Sakhalin. It was disbanded on 20 December 1905.

Marco Polo Bridge Incident
The Marco Polo Bridge Incident, also known as the Lugou Bridge Incident () or the July 7 Incident (), was a July 1937 battle between China's National Revolutionary Army and the Imperial Japanese Army. Since the Japanese invasion of Manchuria in 1931, there had been many small incidents along the rail line connecting Beijing with the port of Tianjin, but all had subsided. On this occasion, a Japanese soldier was temporarily absent from his unit opposite Wanping, and the Japanese commander demanded the right to search the town for him. When this was refused, other units on both sides were put on alert; with tension rising, the Chinese Army fired on the Japanese Army, which further escalated the situation, even though the missing Japanese soldier had returned to his lines. The Marco Polo Bridge Incident is generally regarded as the start of the Second Sino-Japanese War, and arguably World War II. Name In English, the battle is usually known as the "Marco Polo Bridge Incide ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kure Naval Arsenal
was one of four principal naval shipyards owned and operated by the Imperial Japanese Navy. History The Kure Naval District was established at Kure, Hiroshima in 1889, as the second of the naval districts responsible for the defense of the Japanese home islands. Along with the establishment of the navy base, a ship repair facility was also constructed, initially by moving the equipment from the Onohama shipyards near Kobe. Construction was supervised by the French engineer Louis-Émile Bertin. The first warship constructed at Kure, '' Miyako'', was launched in 1897. The "Kure Shipyards" were officially renamed the "Kure Naval Arsenal" in 1903. Kure developed into one of the largest shipbuilding facilities in the Empire of Japan, capable of working with the largest vessels. The Arsenal included a major steel works (built with British assistance), and also facilities for producing naval artillery and projectiles. The battleships ''Yamato'' and '' Nagato'' were designed and con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Japanese Torpedo Boat Tomozuru
was one of four s of the Imperial Japanese Navy (IJN). It capsized in a storm on 12 March 1934, shortly after its completion. This incident forced the IJN to review the stability of all recently completed, under construction and planned ships. It was salvaged and put back into service after extensive modifications. During World War II, the ''Tomozuru'' fought in the Battle of the Philippines and in the Dutch East Indies campaign as an escort, and it continued to play that role for the rest of the war. The ''Tomozuru'' Incident In February 1934, ''Tomozuru'' joined the 21st Torpedo Flotilla at Sasebo. *01:00, 12 March 1934, ''Tomozuru'' departed from Sasebo for a night torpedo exercise with the light cruiser and torpedo boat . *03:25, because of stormy weather, ''Tatsuta'' ordered the other two boats to return to base. *03:58, radio contact lost with ''Tomozuru''.

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] |
Ceremonial Ship Launching
Ceremonial ship launching involves the performance of ceremonies associated with the process of transferring a vessel to the water. It is a nautical tradition in many cultures, dating back thousands of years, to accompany the physical process with ceremonies which have been observed as public celebration and a solemn blessing, usually but not always, in association with the launch itself. Ship launching imposes stresses on the ship not met during normal operation and, in addition to the size and weight of the vessel, represents a considerable engineering challenge as well as a public spectacle. The process also involves many traditions intended to invite good luck, such as christening by breaking a sacrificial bottle of champagne over the bow as the ship is named aloud and launched. Methods There are three principal methods of conveying a new ship from building site to water, only two of which are called "launching". The oldest, most familiar, and most widely used is th ...

Washington Naval Treaty
The Washington Naval Treaty, also known as the Five-Power Treaty, was a treaty signed during 1922 among the major Allies of World War I, which agreed to prevent an arms race by limiting naval construction. It was negotiated at the Washington Naval Conference, held in Washington, D.C., from November 1921 to February 1922, and it was signed by the governments of Great Britain, the United States, France, Italy, and Japan. It limited the construction of battleships, battlecruisers and aircraft carriers by the signatories. The numbers of other categories of warships, including cruisers, destroyers, and submarines, were not limited by the treaty, but those ships were limited to 10,000 tons displacement each. The treaty was concluded on February 6, 1922. Ratifications of that treaty were exchanged in Washington on August 17, 1923, and it was registered in the '' League of Nations Treaty Series'' on April 16, 1924. Later naval arms limitation conferences sought additional limitations o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
