Mikro-Mir 144-016 1/144 German Type UB 1 Submarine
The Type UB I was a class of small coastal submarines (U-boats) built in Germany at the beginning of the First World War.
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 ordered a further three boats in April 1915. A total of 20 UB Is were built. Construction of the first boats for Germany began in early November 1914; all 20 were completed by October 1915. Several of the first boats underwent trials in German home waters, but the rest were assembled and tested at either Antwerp or Pola. The German boats operated primarily in the Flanders, Baltic, and Constantinople Flotillas. The boats were about 28 metres (92 ft) long and displaced 127 tonnes (125 long tons) when surfaced and 142 tonnes (140 long tons) while submerged. All had two bow torpedo tubes and two torpedoes, and were equipped with a deck-mounted machine gun.
