German Type UB I Submarine
The Type ''UB I'' submarine (sometimes known as the ''UB-1'' class) was a class of small coastal submarines (U-boats) built in Germany at the beginning of the First World War. 20 boats were constructed, most of which went into service with the German Imperial Navy.(german: Kaiserliche Marine) Boats of this design were also operated by the Austro-Hungarian Navy (Kaiserliche und Königliche Kriegsmarine ''or'' K.u.K. Kriegsmarine) and the Bulgarian Navy. In the Austro-Hungarian Navy, it was called the . Built to meet the need for small maneuverable submarines able to operate in the narrow, shallow seas off Flanders, the vessels were intended to be quickly constructed, then shipped by rail and assembled at their port of operation. The design effort began in mid-August 1914 and by mid-October the first 15 boats were ordered from two German shipyards. The German Imperial Navy subsequently ordered an additional pair of boats to replace two sold to Austria-Hungary, who ordere ...

German Type UB II Submarine
The UB II type submarine was a class of U-boat built during World War I by the German Imperial Navy. They were enlarged from the preceding type UB I and were more effective vessels. The boats were a single hull design with a 50-metre maximum diving depth and a 30-45 second diving time. In 1915 and 1916, 30 were built at two different shipyards. The design of type UB II addressed many of the problems apparent in the preceding type UB I class. The UB II boats featured a two-shaft drive with a much larger battery capacity and larger engines. Storage batteries were placed forward of the central diving tanks to compensate for the much heavier engine installation. The armament of the type UB II consisted of 50 cm G torpedoes launched from two bow tubes. The torpedo tubes were installed one above the other to allow for a bow design that would create optimal surface efficiency. A 5 cm gun was provided on the deck for surface use. The weight of the boat was increased to 270 ton ...

German Type UB III Submarine
The Type UB III submarine was a class of U-boat built during World War I by the German Imperial Navy. UB III boats carried 10 torpedoes and were usually armed with either an or a deck gun. They carried a crew of 34 and had a cruising range of . Between 1916 and 1918, 96 were built. The UB III type was a coastal submarine, and being a submersible torpedo boat was less akin to UB II type "attack" (i.e. torpedo-launching) boats that preceded it than the highly successful UC II type minelaying submarine. The UC IIs had gained their reputation by sinking more than 1,800 Allied and neutral vessels. German engineers did not miss the chance of expanding the potential of this capable design by incorporating some of its features into a new submersible torpedo boat. The UB IIIs joined the conflict mid-1917, after the United States declared war on Germany and the United States Navy was added to the ranks of their enemies. When the convoy system was introduced, it became more difficult ...
