Type IX U-boat
The Type IX U-boat was designed by Nazi Germany's ''Kriegsmarine'' in 1935 and 1936 as a large ocean-going submarine for sustained operations far from the home support facilities. Type IX boats were briefly used for patrols off the eastern United States in an attempt to disrupt the stream of troops and supplies bound for Europe. It was derived from the Type IA, and appeared in various sub-types. Type IXs had six torpedo tubes; four at the bow and two at the stern. They carried six reloads internally and had five external torpedo containers (three at the stern and two at the bow) which stored ten additional torpedoes. The total of 22 torpedoes allowed U-boat commanders to follow a convoy and strike night after night. Some of the IXC boats were fitted for mine operations; as mine-layers they could carry 44 TMA or 66 TMB mines. Secondary armament was provided by one deck gun with 180 rounds. Anti-aircraft armament differed throughout the war. They had two periscopes in the towe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type I Submarine
The Type I U-boat was the first post–World War I attempt to produce an oceangoing submarine for Nazi Germany's ''Kriegsmarine''. Only two Type IAs were built, but the decision to halt production on further boats is believed to be because of political decisions and not because of major faults in the Type I design. Although the boats did not have any major design faults, they were known to be difficult to handle due to their poor stability and slow dive rate. The type was based on the design of the Finnish ''Vetehinen'' class and the Spanish Type E-1, designed by Ingenieurskantoor voor Scheepsbouw (the company also designed the Soviet S class submarine). The design later served as a basis for the development of other types of boats, primarily the VII and IX classes. Constructed by Deschimag in Bremen, the first Type IA was launched on 14 February 1936. The two boats produced, and , were primarily used as training vessels and for propaganda purposes to fly the Nazi flag. In 19 ...

Pressure Hull
A submarine hull has two major components, the ''light hull'' and the ''pressure hull''. The light hull (''casing'' in British usage) of a submarine is the outer non-watertight hull which provides a hydrodynamically efficient shape. The pressure hull is the inner hull of a submarine that maintains structural integrity with the difference between outside and inside pressure at depth. Shapes Modern submarines are usually cigar-shaped. This design, already visible on very early submarines, is called a "teardrop hull". It is structurally efficient for withstanding external pressure, and significantly reduces the hydrodynamic drag on the sub when submerged, but decreases the sea-keeping capabilities and increases drag while surfaced. History The concept of an outer hydrodynamically streamlined light hull separated from the inner pressure hull was first introduced in the early pioneering submarine Ictineo I designed by the Spanish inventor Narcís Monturiol in 1859. However, whe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deutsche Werft
Deutsche Werft (English: German Shipyard) was a shipbuilding company in Finkenwerder Rüschpark, Hamburg, Germany. It was founded in 1918 by Albert Ballin and with Gutehoffnungshütte (GHH), ''Allgemeine Elektricitäts-Gesellschaft'' ( AEG) and '' Hamburg Amerikanische Packetfahrt Actien Gesellschaft'' (HAPAG) as investors. In peacetime, Deutsche Werft built merchant ships, such as the HAPAG turbo-electric cargo ships and . In World War II Deutsche Werft built 113 Type IX and XXIII U-boats for the '' Kriegsmarine''. To this end, it operated three camps directly on the company premises (the Deutsche Werft construction site camp, Deutsche Werft Finkenwärder camp and the Rüschkanal Eastern workers' camp), was involved in five camps in the Finkenwerder district and six in the port area, as well as nine camps in the city area. In addition, there were the camps at the Reiherstiegwerft shipyard, which also belonged to Deutsche Werft. In 1968 Deutsche Werft was merged and became pa ...

Seebeckwerft
Seebeckwerft A.G. was a German shipbuilding company, located in Bremerhaven at the mouth of the river Weser. Founded in 1876, it became later one of the leading shipbuilding companies in the region. History Seebeckwerft was founded in 1876 in Bremerhaven by ''Georg Seebeck'' (1845 – 1928), a young coppersmith, born in Brake at the Lower-Weser river. In 1876 Georg Seebeck founded a small metal-processing workshop in Geestemünde, a part of the city of Bremerhaven. In 1879 the first ship was constructed, a small steamer. In 1928 the Seebeckwerft became a member of the Deschimag, a cooperation of several German shipyards under the leadership of the Bremen-shipyard A.G. Weser. After WW II the Deschimag was dissolved and Seebeckwerft became subsidiary of A.G. Weser, now named A.G. Weser Seebeckwerft. During World War II Seebeckwerft built 16 Type IX U-boats for the Kriegsmarine. In 1988 the company merged with Schichau Unterweser to become Schichau Seebeckwerft. Ships built by ...
