Japanese Type 6 Submarine
The was the first class of submarines of the Imperial Japanese Navy built domestically in Japan. Consisting of two vessels, these submarines were highly modified versions of ''Holland''-class vessels designed in the United States. Background During the Russo-Japanese War, the Japanese government had purchased five modified ''Holland''-class submarines from the Electric Boat Company's Fore River Shipyards in Quincy, Massachusetts.Jentschura p. 160 These vessels, known as the Type 1 class were delivered to Japan in knock-down form, and re-assembled at the Yokosuka Naval Arsenal. However, simultaneously, the Japanese government had obtained copies of the blueprints for the ''Holland''-class submarines, and had assigned Kawasaki Dockyards in Kobe the task of building similar vessels in Japan. Construction and operational history Kawasaki built two boats (Hulls No. 6 and 7), with the help of two American engineers, Chase and Herbert, who had been assistants to John Philip Holl ...

General Dynamics Electric Boat
General Dynamics Electric Boat (GDEB) is a subsidiary of General Dynamics Corporation. It has been the primary builder of submarines for the United States Navy for more than 100 years. The company's main facilities are a shipyard in Groton, Connecticut, a hull-fabrication and outfitting facility in Quonset Point, Rhode Island, and a design and engineering facility in New London, Connecticut. History The company was founded in 1899 by Isaac Rice as the Electric Boat Company to build John Philip Holland's submersible ship designs, which were developed at Lewis Nixon's Crescent Shipyard in Elizabeth, New Jersey. ''Holland VI'' was the first submarine that this shipyard built, which became when it was commissioned into the United States Navy on April 11, 1900—the first submarine to be officially commissioned. The success of ''Holland VI'' created a demand for follow-up models (A class or ) that began with the prototype submersible ''Fulton'' built at Electric Boat. Some f ...

Submarine Classes
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 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 navies, large and small. Military uses include attacking enemy surface ships (merchant and military) or other submarines, and for aircraft carrier protection, blockade running, nuclear deterrence, reconnaissance, conventional land attack (for example, using a cruise missile), and covert insertion ...

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 o-yatoi gaikokujin, French engineer Louis-Émile Bertin. The first warship constructed at Kure, ''Miyako (ship), 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 ''Japanese battl ...

Supreme Commander For The Allied Powers
was the title held by General Douglas MacArthur during the United States-led Allied occupation of Japan following World War II. It issued SCAP Directives (alias SCAPIN, SCAP Index Number) to the Japanese government, aiming to suppress its "militaristic nationalism". The position was created at the start of the occupation of Japan on August 14, 1945. In Japan, the position was generally referred to as GHQ (General Headquarters), as SCAP also referred to the offices of the occupation (which was officially referred by SCAP itself as ), including a staff of several hundred US civil servants as well as military personnel. Some of these personnel effectively wrote a first draft of the Japanese Constitution, which the National Diet then ratified after a few amendments. Australian, British Empire, and New Zealand forces under SCAP were organized into a sub-command known as British Commonwealth Occupation Force. These actions led MacArthur to be viewed as the new Imperial force in Ja ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
