German Empire
The German Empire (),Herbert Tuttle wrote in September 1881 that the term "Reich" does not literally connote an empire as has been commonly assumed by English-speaking people. The term literally denotes an empire – particularly a hereditary empire led by an emperor, although has been used in German to denote the Roman Empire because it had a weak hereditary tradition. In the case of the German Empire, the official name was , which is properly translated as "German Empire" because the official position of head of state in the constitution of the German Empire was officially a "presidency" of a confederation of German states led by the King of Prussia who would assume "the title of German Emperor" as referring to the German people, but was not emperor of Germany as in an emperor of a state. –The German Empire" ''Harper's New Monthly Magazine''. vol. 63, issue 376, pp. 591–603; here p. 593. also referred to as Imperial Germany, the Second Reich, as well as simply Germany, ...

Prize Rules
In admiralty law prizes are equipment, vehicles, vessels, and cargo captured during armed conflict. The most common use of ''prize'' in this sense is the capture of an enemy ship and her cargo as a prize of war. In the past, the capturing force would commonly be allotted a share of the worth of the captured prize. Nations often granted letters of marque that would entitle private parties to capture enemy property, usually ships. Once the ship was secured on friendly territory, she would be made the subject of a prize case: an ''in rem'' proceeding in which the court determined the status of the condemned property and the manner in which the property was to be disposed of. History and sources of prize law In his book ''The Prize Game'', Donald Petrie writes, "at the outset, prize taking was all smash and grab, like breaking a jeweler's window, but by the fifteenth century a body of guiding rules, the maritime law of nations, had begun to evolve and achieve international recogni ...

Displacement (ship)
The displacement or displacement tonnage of a ship is its weight. As the term indicates, it is measured indirectly, using Archimedes' principle, by first calculating the volume of water displaced by the ship, then converting that value into weight. Traditionally, various measurement rules have been in use, giving various measures in long tons. Today, tonnes are more commonly used. Ship displacement varies by a vessel's degree of load, from its empty weight as designed (known as "lightweight tonnage") to its maximum load. Numerous specific terms are used to describe varying levels of load and trim, detailed below. Ship displacement should not be confused with measurements of volume or capacity typically used for commercial vessels and measured by tonnage: net tonnage and gross tonnage. Calculation The process of determining a vessel's displacement begins with measuring its draft.George, 2005. p.5. This is accomplished by means of its "draft marks" (or "load lines"). A mer ...

Sasebo Navy Yard
was one of four principal naval shipyards owned and operated by the Imperial Japanese Navy. History The Sasebo Naval District was established at Sasebo, Nagasaki in 1886, as the third of the naval districts responsible for the defense of the Japanese home islands. After the establishment of the navy base, a ship repair facility was established in 1889 with a dry dock. With the addition of equipment and facilities for ship production by 1897, the "Sasebo Shipyards" were officially established, and renamed the "Sasebo Naval Arsenal" in 1903. Construction of the arsenal was supervised by the French engineer Louis-Émile Bertin. In 1913, a 250-ton crane was installed, and the shipbuilding facilities expanded to permit the construction of large warships. With the mothballing of the Maizuru Naval Arsenal due to restrictions by the Washington Naval Treaty, much of the design and prototype work for new classes of destroyers and torpedo boats formerly done at Maizuru was shifted to ...

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. After t ...
