Wakatake-class Destroyer
The were a class of eight second-class destroyers of the Imperial Japanese Navy. Background The medium-sized ''Wakatake''-class destroyers were a follow-on to the as part of the Imperial Japanese Navy's 8-6 Fleet Program from fiscal 1921 as a lower cost accompaniment to the larger s. The class was originally planned to consist of thirteen vessels, but due to the Washington Naval Treaty, as well as budgetary limitations, the orders for the last four were cancelled in 1922, with the final number being reduced to eight when ''No.14'' was also cancelled. The ''Wakatake'' class was the last class to be rated "second class" and all future destroyers were designed larger. It was planned that the ''Wakatake''-class ships should have names, but upon completion they were given numbers. This proved to be extremely unpopular with the crews and was a constant source of confusion in communications, so in 1928, names were assigned. Design The ''Wakatake''-class destroyers were essentially sli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fujinagata Shipyards
was a shipyard and railroad car manufacturer in Osaka, Japan. History Fujinagata claimed to have been founded in 1689, making it one of the oldest shipbuilders in Japan. Originally called ''Hyōgo-ya'', and located in central Osaka, it was contracted in 1854 by officials representing the Tokugawa shogunate to produce sail warships for the new Tokugawa feudal navy. In 1869, with the assistance of German engineers, the western-style warships were designed and produced. After the Meiji Restoration, the shipyards concentrated on civilian applications, and in 1870 launched its first western-style commercial steam vessel. This was a first for a privately held shipbuilder in Japan. In 1874, the shipyards were relocated to Nishi-ku, Osaka and the company name officially changed to Fujinagata Shipyards. In 1884, the main shipyards was relocated to Taisho-ku, Osaka. In 1900, Fujinagata completed its first all-metal construction merchant vessel; the No.2 '' Nagata Maru''. In 1917, new ...

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] |
Bungo Strait
The is a strait separating the Japanese islands of Kyushu and Shikoku. It connects the Philippine Sea and the Seto Inland Sea on the western end of Shikoku. The narrowest part of this channel is the Hōyo Strait.

Seto Inland Sea
The , sometimes shortened to the Inland Sea, is the body of water separating Honshu, Shikoku, and Kyushu, three of the four main islands of Japan. It serves as a waterway connecting the Pacific Ocean to the Sea of Japan. It connects to Osaka Bay and provides a sea transport link to industrial centers in the Kansai region, including Osaka and Kobe. Before the construction of the San'yō Main Line, it was the main transportation link between Kansai and Kyūshū. Yamaguchi, Hiroshima, Okayama, Hyōgo, Osaka, Wakayama, Kagawa, Ehime, Tokushima, Fukuoka, and Ōita prefectures have coastlines on the Seto Inland Sea; the cities of Hiroshima, Iwakuni, Takamatsu, and Matsuyama are also located on it. The Setouchi region encompasses the sea and surrounding coastal areas. The region is known for its moderate climate, with a stable year-round temperature and relatively low rainfall levels.

Kure Naval District
was the second of four main administrative districts of the pre-war Imperial Japanese Navy. Its territory included the Inland Sea of Japan and the Pacific coasts of southern Honshū from Wakayama to Yamaguchi prefectures, eastern and northern Kyūshū and Shikoku. The area of the Kure Naval District encompassed Hashirajima Anchoring Area located at the south end of Hiroshima Bay, 30-40 kilometers southwest of Kure. When not in need of repairs ships usually anchored in this area to free up pier space at Kure. Hashirajima was also a major staging area for fleet operations. Tokuyama port, was also part of Kure Naval District, and had the largest fuel depot in the Japanese Navy. History The location of 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. With the formation of the navy in 1886, Japan was divided into five naval districts fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Main Battery
A main battery is the primary weapon or group of weapons around which a warship is designed. As such, a main battery was historically a naval gun or group of guns used in volleys, as in the broadsides of cannon on a ship of the line. Later, this came to be turreted groups of similar large-caliber naval rifles. With the evolution of technology the term has come to encompass guided missiles and torpedoes as a warship's principal offensive weaponry, deployed both on surface ships and submarines. A main battery features common parts, munition and fire control system across the weapons which it comprises. Description In the age of cannon at sea, the main battery was the principal group of weapons around which a ship was designed, usually its heavies. With the coming of naval rifles and subsequent revolving gun turrets, the main battery became the principal group of heaviest guns, regardless of how many turrets they were placed in. As missiles displaced guns both above and belo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Brown & Company
John Brown and Company of Clydebank was a Scottish Naval architecture, marine engineering and shipbuilding firm. It built many notable and world-famous ships including , , , , , and ''Queen Elizabeth 2 (ship), Queen Elizabeth 2''. At its height, from 1900 to the 1950s, it was one of the most highly regarded, and internationally famous, shipbuilding companies in the world. However thereafter, along with other UK shipbuilders, John Brown's found it increasingly difficult to compete with the emerging shipyards in Eastern Europe and the far East. In 1968 John Brown's merged with other Clydeside shipyards to form the Upper Clyde Shipbuilders consortium, but that collapsed in 1971. The company then withdrew from shipbuilding but its engineering arm remained successful in the manufacture of industrial gas turbines. In 1986 it became a wholly owned subsidiary of Trafalgar House (company), Trafalgar House, which in 1996 was taken over by Kvaerner. The latter closed the Clydebank engine ...

Steam Turbine
A steam turbine or steam turbine engine is a machine or heat engine that extracts thermal energy from pressurized steam and uses it to do mechanical work utilising a rotating output shaft. Its modern manifestation was invented by Sir Charles Parsons in 1884. It revolutionized marine propulsion and navigation to a significant extent. Fabrication of a modern steam turbine involves advanced metalwork to form high-grade steel alloys into precision parts using technologies that first became available in the 20th century; continued advances in durability and efficiency of steam turbines remains central to the energy economics of the 21st century. The largest steam turbine ever built is the 1,770 MW Arabelle steam turbine built by Arabelle Solutions (previously GE Steam Power), two units of which will be installed at Hinkley Point C Nuclear Power Station, England. The steam turbine is a form of heat engine that derives much of its improvement in thermodynamic efficiency from the u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
