Kuma-class Cruisers
The were a class of five light cruisers built for and operated by the Imperial Japanese Navy (IJN). The ''Kuma''-class cruisers proved useful in combat operations ranging from the Aleutian Islands to the Indian Ocean throughout World War II. The ''Kuma''-class was followed by the very similar . Background Despite the success of the high speed light cruiser design, the Imperial Japanese Navy realized that they would be outgunned by the larger US Navy and the Dutch Java-class of light cruisers then under development. In addition, the ''Tenryū''-class vessels, with a maximum speed of , were unable to keep up with the newer Japanese destroyers, such as the , which had a design speed of .Stille, '' Imperial Japanese Navy Light Cruisers 1941-45 '', pages 14-18; At the end of 1917, plans for an additional six ''Tenryū''-class vessels, plus three new-design 7200 ton-class scout cruisers were shelved, in place of an intermediate 5,500 ton-class vessel which could be used as both a ...

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. Through their history they served in a variety of roles, primarily as convoy escorts and destroyer command ships, but also as scouts and fleet support vessels for battle fleets. Origins and development The first small steam-powered cruisers were built for the British Royal Navy with HMS ''Mercury'' launched in 1878. Such second and third class protected cruisers evolved, gradually becoming faster, better armed and better protected. Germany took a lead in small crui ...

Torpedo Cruiser
A torpedo cruiser is a type of warship that is armed primarily with torpedoes. The major navies began building torpedo cruisers shortly after the invention of the locomotive Whitehead torpedo in the 1860s. The development of the torpedo gave rise to the ''Jeune École'' doctrine, which held that small warships armed with torpedoes could effectively and cheaply defeat much larger battleships. Torpedo cruisers fell out of favor in most of the great power navies in the 1890s, though many other navies continued to acquire them into the early 1900s. The Imperial Japanese Navy rebuilt two light cruisers into torpedo cruisers during World War II. Unlike the earlier vessels, these ships were intended to launch their Long Lance oxygen torpedoes at extreme range at night to surprise enemy warships. They never saw action in their intended role, however, and were quickly converted into troop transports. History The torpedo cruiser emerged from the ''Jeune École'', a strategic naval concep ...

Imperial Japanese Navy General Staff
The was the highest organ within the Imperial Japanese Navy. In charge of planning and operations, it was headed by an Admiral headquartered in Tokyo. History Created in 1893, the Navy General Staff took over operational (as opposed to administrative) authority over the Imperial Japanese Navy from the Navy Ministry. It was responsible for the planning and execution of national defense strategy. Through the Imperial General Headquarters it reported directly to the Emperor, not to the Prime Minister, National Diet or even the Navy Ministry. It was always headed by an admiral on active duty, and was based in Tokyo. "The ministry was responsible for the naval budget, ship construction, weapons procurement, personnel, relations with the Diet and the cabinet and broad matters of naval policy. The General Staff directed the operations of the fleet and the preparation of war plans".Spector After the Washington Naval Conference of 1921–22, where Japan agreed to keep the size of its ...

Type 93 Torpedo
The was a -diameter torpedo of the Imperial Japanese Navy (IJN), launched from surface ships. It is commonly referred to as the Long Lance by most modern English-language naval historians, a nickname given to it after the war by Samuel Eliot Morison, the chief historian of the U.S. Navy, who spent much of the war in the Pacific Theater. In Japanese references, the term is also used, in reference to its propulsion system. It was the most advanced naval torpedo in the world at the time. History and development The Type 93's development (in parallel with a submarine-launched model, the Type 95) began in Japan in 1928, under the auspices of Rear Admiral Kaneji Kishimoto and Captain Toshihide Asakuma. The torpedo design was inspired by the British oxygen-enriched torpedoes used on the s. At the time, the most powerful potential enemy of the Japanese Navy was the United States Navy's Pacific Fleet.

Submarine
A submarine (or sub) is a watercraft capable of independent operation underwater. It differs from a submersible, which has more limited underwater capability. The term is also sometimes used historically or colloquially to refer to remotely operated vehicles and Autonomous underwater vehicle, robots, as well as medium-sized or smaller vessels, such as the midget submarine and the wet sub. Submarines are referred to as ''boats'' rather than ''ships'' irrespective of their size. Although experimental submarines had been built earlier, submarine design took off during the 19th century, and they were adopted by several navies. They were first widely used during World War I (1914–1918), and are now used in many navy, navies, large and small. Military uses include attacking enemy surface ships (merchant and military) or other submarines, and for aircraft carrier protection, Blockade runner, blockade running, Ballistic missile submarine, nuclear deterrence, reconnaissance, conventio ...

Scout Cruiser
A scout cruiser was a type of warship of the early 20th century, which were smaller, faster, more lightly armed and armoured than protected cruisers or light cruisers, but larger than contemporary destroyers. Intended for fleet scouting duties and acting as a flotilla leader, a scout cruiser was typically armed with six to ten destroyer-type guns of 3-inch (76 mm) to 4.7-inch (120 mm) calibre, plus two to four torpedo tubes. The British were the first to operate scout cruisers, when the Royal Navy acquired 15 ships divided into two distinct groups - the eight vessels all ordered under the 1903 Programme, and the seven later, heavier-armed vessels ordered under the 1907–1910 Programmes. All these ships served in World War I, when the advent of better machinery and larger, faster destroyers and light cruisers had already made them obsolete. The other major operator of scout cruisers was the Kingdom of Italy. With no conventional protected cruisers or light cruisers planned betwe ...

Destroyer
In naval terminology, a destroyer is a fast, manoeuvrable, long-endurance warship intended to escort larger vessels in a fleet, convoy or battle group and defend them against powerful short range attackers. They were originally developed 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 unattended o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Java-class Cruiser
The ''Java'' class was a class of light cruisers of the Royal Netherlands Navy, with the lead ship named after the island of Java in the Dutch East Indies. Originally, three ships were planned: ''Java'', ''Sumatra'', and ''Celebes''. ''Celebes'' was intended to be the flagship of the naval commander in the Dutch East Indies, and therefore she was slightly bigger than the other two ships. However, the contract was cancelled with 30 tons of material already prepared (a new ship, was later built to fill that requirement). The class was designed by the Dutch with technical oversight by the German company Krupp, and constructed in the Netherlands. Armed with ten guns, they were of comparable capability to the German and British cruisers designs of the time. However, these were not turret-mounted, and by the time the cruisers were finally launched after all the delays caused by the upheaval of World War I (''Sumatra'' in 1920, ''Java'' in 1921), the ships had already become ...

Koninklijke Marine
The Royal Netherlands Navy ( nl, Koninklijke Marine, links=no) is the naval force of the Kingdom of the Netherlands. During the 17th century, the navy of the Dutch Republic (1581–1795) was one of the most powerful naval forces in the world and played an active role in the Anglo-Dutch Wars, the Franco-Dutch War, and wars against Spain and several other European powers. The Batavian Navy of the later Batavian Republic (1795–1806) and Kingdom of Holland (1806–1810) played an active role in the Napoleonic Wars, though mostly dominated by French interests. After the establishment of the modern Kingdom of the Netherlands, it served an important role in protecting Dutch Empire, Dutch colonial rule, especially in Southeast Asia, and would play a minor role in World War II, especially against the Imperial Japanese Navy. Since World War II, the Royal Netherlands Navy has taken part in expeditionary peacekeeping operations. Bases The main naval base is in Den Helder, North Holland. ...

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] |
