Ha-1-class Submarine
The was an early class of submarines of the Imperial Japanese Navy, and were essentially British C-class submarines, which had been imported for evaluation and reverse engineering. Background Following its experiment during and after the Russo-Japanese War with modified versions of the ''Holland''-class vessels designed in the United States, the Imperial Japanese Navy turned to the United Kingdom, which had continued development of the Holland design with 13 vessels in its , 11 vessels in its B class and 38 vessels in its C class. The Japanese government contracted Vickers at Barrow-in-Furness for two vessels, which were laid down just after towards the end of the C-class production run for the Royal Navy. The completed vessels were shipped to Japan on a specially modified cargo vessel. With limited endurance and only a ten percent reserve of buoyancy over their surface displacement, The ''Ha-1'' class were poor surface vessels, but their spindle shaped hull made for good un ...

Vickers Shipbuilding And Engineering
Vickers Shipbuilding and Engineering, Ltd (VSEL) was a shipbuilding company based at Barrow-in-Furness, Cumbria in northwest England that built warships, civilian ships, submarines and armaments. The company was historically the Naval Construction Works of Vickers Armstrongs and has a heritage of building large naval warships and armaments. Through a complicated history the company's shipbuilding division is now BAE Systems Submarine Solutions and the armaments division is now part of BAE Systems Land & Armaments. History The company was founded in 1871 by James Ramsden as the Iron Shipbuilding Company, but its name was soon changed to Barrow Shipbuilding Company. In 1897, ''Vickers & Sons'' bought the ''Barrow Shipbuilding Company'' and its subsidiary the ''Maxim Nordenfelt Guns and Ammunition Company'', becoming ''Vickers, Sons and Maxim, Limited''. The shipyard at Barrow became the Naval Construction & Armaments Company. In 1911 the company was renamed ''Vickers Ltd'', and ...

British B-class Submarine
The B class was a class of 11 submarines, built by Vickers in Barrow-in-Furness for the Royal Navy, and launched in 1904–06. One boat was sunk by a collision in 1912, but the remainder served in World War I. Three boats protected the transfer of the British Expeditionary Force to France in 1914, but were soon relegated to local defence and training duties. Six submarines were in the Mediterranean when the war began and were quickly sent to the Dardanelles to prevent a breakout by the German battlecruiser and the light cruiser into the Eastern Mediterranean. ''B11'' ventured into the Dardanelles in December 1914 and sank the elderly Turkish ironclad . The arrival of more modern submarines to blockade the Dardanelles made the B-class boats redundant and they were mostly withdrawn to Malta in 1915. They were transferred to Venice after Italy entered the war, where ''B10'' became the first submarine to be sunk by air attack in 1916. The B-class submarines were transferred back ...

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 Compa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 of ...

British 18 Inch Torpedo
There have been a number of 18-inch torpedoes in service with the United Kingdom. These have been used on ships of the Royal Navy and aircraft of both the Fleet Air Arm and Royal Air Force, while Royal Navy surface ships and submarines use 21-inch torpedoes. The British "18-inch" torpedoes were in diameter, beginning with the "Fiume" Whitehead torpedo of 1890. 45 cm "Fiume" (Whitehead) torpedo First introduced into British service in 1894. * Year : about 1888 * Weight : * Length : * Warhead : wet gun-cotton * Performance : for * Propulsion : Compressed air Mark V Used on the River-class and 1905 Tribal-class destroyers. * Year : about 1899 * Weight : * Warhead : including pistol * Propulsion : Compressed air Mark VI Used on destroyers of the early 1900s. * Year : about 1904 * Performance : for or for * Propulsion : Compressed air Mark VII and VII* Introduced on the 1908 members of the 1905 Tribal class destroyers.

Wolseley Motors
Wolseley Motors Limited was a British motor vehicle manufacturer founded in early 1901 by the Vickers Armaments in conjunction with Herbert Austin. It initially made a full range, topped by large luxury cars, and dominated the market in the Edwardian era. The Vickers brothers diedin 1914 and 1919 respectively and, without their guidance, Wolseley expanded rapidly after the war, manufacturing 12,000 cars in 1921, and remained the biggest motor manufacturer in Britain. Over-expansion led to receivership in 1927 when it was bought from Vickers Limited by William Morris as a personal investment. He moved it into his Morris Motors empire just before the Second World War. After that, Wolseley products were "badge-engineered" Morris cars. Wolseley went with its sister businesses into BMC, BMH and British Leyland, where its name lapsed in 1975.
