Japanese Cruiser Jintsū
was the second vessel completed in the three-ship light cruiser in the Imperial Japanese Navy (IJN), named after the Jinzū River in the Gifu Prefecture, Gifu and Toyama Prefecture, Toyama prefectures of central Japan. She was active in World War II in various campaigns including the Philippines campaign (1941–1942), Japanese invasion of the Philippines, the Battle of the Java Sea, and Battle of Midway. On 13 July 1943 in the Battle of Kolombangara, she was discovered during a night attack by American ships and sunk in combat. Background The ''Sendai''-class vessels were part of the Eight-eight fleet program, with the first four of eight planned vessels authorized in 1921. However, due to the Washington Naval Treaty, the final four vessels were never authorized, and the fourth vessel was cancelled during construction, as the Japanese Navy decided to concentrate on heavy cruiser procurement instead.Stille, '' Imperial Japanese Navy Light Cruisers 1941–45 '', page 27–30; '' ...

Empire Of Japan
The Empire of Japan, also known as the Japanese Empire or Imperial Japan, was the Japanese nation state that existed from the Meiji Restoration on January 3, 1868, until the Constitution of Japan took effect on May 3, 1947. From Japan–Korea Treaty of 1910, 1910 to Japanese Instrument of Surrender, 1945, it included the Japanese archipelago, the Kuril Islands, Kurils, Karafuto Prefecture, Karafuto, Korea under Japanese rule, Korea, and Taiwan under Japanese rule, Taiwan. The South Seas Mandate and Foreign concessions in China#List of concessions, concessions such as the Kwantung Leased Territory were ''de jure'' not internal parts of the empire but dependent territories. In the closing stages of World War II, with Japan defeated alongside the rest of the Axis powers, the Japanese Instrument of Surrender, formalized surrender was issued on September 2, 1945, in compliance with the Potsdam Declaration of the Allies of World War II, Allies, and the empire's territory subsequent ...

Light Cruiser
A light cruiser is a type of small or medium-sized warship. The term is a shortening of the phrase "light armored cruiser", describing a small ship that carried armor in the same way as an armored cruiser: a protective belt and deck. Prior to this smaller cruisers had been of the protected cruiser model, possessing armored decks only. While lighter and smaller than other contemporary ships they were still true cruisers, retaining the extended radius of action and self-sufficiency to act independently around the world. Cruisers mounting larger guns and heavier armor relative to most light cruisers would come to be known as heavy cruisers, though the designation of 'light' versus 'heavy' cruisers would vary somewhat between navies. Through their history light cruisers served in a variety of roles, primarily on long-range detached patrol work, covering other military operations or global shipping lanes, as scouts and fleet support vessels for battle fleets, as destroyer command ship ...

Keel Laying
Laying the keel or laying down is the formal recognition of the start of a shipbuilding, ship's construction. It is often marked with a ceremony attended by dignitaries from the shipbuilding company and the ultimate owners of the ship. Keel laying is one of the four specially celebrated events in a ship's life; the others are Ceremonial ship launching, launching, Ship commissioning, commissioning, and Ship decommissioning, decommissioning. Earlier, the event recognized as the keel laying was the initial placement of the central timber making up the backbone of a vessel, called the keel. As steel ships replaced wooden ones, the central timber gave way to a central steel beam. Modern ships are most commonly built in a series of pre-fabricated, complete hull sections rather than around a single keel. The event recognized as the keel laying is the first joining of modular components, or the lowering of the first module into place in the building dock. It is now often called "keel ...

Belt Armor
Belt armor is a layer of heavy metal armor plated onto or within the outer hulls of warships, typically on battleships, battlecruisers and cruisers, and aircraft carriers. The belt armor is designed to prevent projectiles from penetrating to the heart of a warship. When struck by an artillery shell or underwater torpedo, the belt armor either absorbs the impact and explosion with its sheer thickness and strength, or else uses sloping to redirect the projectile and its blast downwards. Typically, the main armor belt covers the warship from its main deck down to some distance below the waterline. If, instead of forming the outer hull, the armor belt is built inside the hull, it is installed at a sloped angle for improved protection, as described above. The torpedo bulkhead Frequently, the main belt's armor plates were supplemented with a torpedo bulkhead spaced several meters behind the main belt, designed to maintain the ship's watertight integrity even if the main belt ...

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 ...

Destroyer
In naval terminology, a destroyer is a fast, maneuverable, long-endurance warship intended to escort larger vessels in a fleet, convoy, or carrier battle group and defend them against a wide range of general threats. They were conceived in 1885 by Fernando Villaamil for the Spanish NavySmith, Charles Edgar: ''A short history of naval and marine engineering.'' Babcock & Wilcox, ltd. at the University Press, 1937, page 263 as a defense against torpedo boats, and by the time of the Russo-Japanese War in 1904, these "torpedo boat destroyers" (TBDs) were "large, swift, and powerfully armed torpedo boats designed to destroy other torpedo boats". Although the term "destroyer" had been used interchangeably with "TBD" and "torpedo boat destroyer" by navies since 1892, the term "torpedo boat destroyer" had been generally shortened to simply "destroyer" by nearly all navies by the First World War. Before World War II, destroyers were light vessels with little endurance for unatte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heavy Cruiser
A heavy cruiser was a type of cruiser, a naval warship designed for long range and high speed, armed generally with naval guns of roughly 203 mm (8 inches) in calibre, whose design parameters were dictated by the Washington Naval Treaty of 1922 and the London Naval Treaty of 1930. Heavy cruisers were generally larger, more heavily armed and more heavily armoured than light cruisers while being smaller, faster, and more lightly armed and armoured than battlecruisers and battleships. Heavy cruisers were not considered capital ships, unlike battlecruisers, battleships, and fleet carriers. Heavy cruisers were assigned a variety of roles ranging from commerce raiding to serving as 'cruiser-killers,' i.e. hunting and destroying similarly sized ships. The heavy cruiser is part of a lineage of ship design from 1915 through the early 1950s, although the term "heavy cruiser" only came into formal use in 1930. The heavy cruiser's immediate precursors were the light cruiser design ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Washington Naval Treaty
The Washington Naval Treaty, also known as the Five-Power Treaty, was signed during 1922 among the major Allies of World War I, Allies of World War I, which agreed to prevent an arms race by limiting Navy, naval construction. It was negotiated at the Washington Naval Conference in Washington, D.C. from November 1921 to February 1922 and signed by the governments of the British Empire (including the United Kingdom, Canada, Australia, New Zealand, South Africa and India), United States, French Third Republic, France, Kingdom of Italy, Italy, and Empire of Japan, 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 (ship), displacement each. The treaty was finalized on February 6, 1922. Ratifications of it were exchanged in Washington on August 17, 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The Philippines campaign (, , ), also known as the Battle of the Philippines () or the Fall of the Philippines, was the invasion of the Commonwealth of the Philippines, Philippines by the Empire of Japan during the Pacific War, Pacific Theater of World War II. The operation to capture the islands, which was defended by the U.S. and Philippine Armies, was intended to prevent interference with Japan's expansion in Southeast Asia. On 8 December 1941, several hours after the attack on Pearl Harbor, Japanese planes began bombing U.S. forces in the Philippines, including Attack on Clark Field, aircraft at Clark Field near the capital of Manila on the island of Luzon.
