Submarines Of The Imperial Japanese Navy
Imperial Japanese Navy submarines originated with the purchase of five Holland type submarines from the United States in 1904. Japanese submarine forces progressively built up strength and expertise, becoming by the beginning of World War II one of the world's most varied and powerful submarine fleets. Origins The Imperial Japanese Navy (IJN) acquired its first submarines during the Russo-Japanese War on 12 December 1904 where they arrived in sections at the Yokohama dockyards. The vessels were purchased from the relatively new American company, Electric Boat, and were fully assembled and ready for combat operations by August 1905.Jentschura p. 160 However, hostilities with Russia were nearing its end by that date, and no submarines saw action during the war. The submarines that Electric Boat sold to Japan were based on the Holland designs, known as Holland Type VIIs similar to the American s. The five imported Hollands were originally built at Fore River Ship and Engine Comp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Modern buildings, an aqueduct (water supply), aqueduct, foundry, brick factories, and technical schools to train Japanese technicians were established. After the Boshin War and the Meiji Restoration, the new Meiji government took over control of the facility in 1871, renaming it the ''Yokosuka Zosenjo'' (Yokosuka Shipyards). The first dry ...

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.

Torpedo
A modern torpedo is an underwater ranged weapon launched above or below the water surface, self-propelled towards a target, with an explosive warhead designed to detonate either on contact with or in proximity to the target. Historically, such a device was called an automotive, automobile, locomotive, or fish torpedo; colloquially, a ''fish''. The term ''torpedo'' originally applied to a variety of devices, most of which would today be called mines. From about 1900, ''torpedo'' has been used strictly to designate a self-propelled underwater explosive device. While the 19th-century battleship had evolved primarily with a view to engagements between armored warships with large-caliber guns, the invention and refinement of torpedoes from the 1860s onwards allowed small torpedo boats and other lighter surface vessels, submarines/submersibles, even improvised fishing boats or frogmen, and later light aircraft, to destroy large ships without the need of large guns, though somet ...
