German submarine U-1 was the first U-boat (or submarine) built for Nazi Germany's Kriegsmarine following Adolf Hitler's abrogation of the terms of the Treaty of Versailles in 1935, which banned Germany possessing a submarine force.

A Type IIA U-boat, she was built at the Deutsche Werke shipyards in Kiel, yard number 236, her keel being laid on 11 February 1935 amid celebration. She was commissioned on 29 June 1935 after a very rapid construction, and was manned by crews trained in the Netherlands.

Design

German Type II submarines were based on the Шаблон:Ship. U-1 had a displacement of Шаблон:Convert when at the surface and Шаблон:Convert while submerged. Officially, the standard tonnage was Шаблон:Convert, however.Шаблон:Sfn The U-boat had a total length of Шаблон:Convert, a pressure hull length of Шаблон:Convert, a beam of Шаблон:Convert, a height of Шаблон:Convert, and a draught of Шаблон:Convert. The submarine was powered by two MWM RS 127 S four-stroke, six-cylinder diesel engines of Шаблон:Convert for cruising, two Siemens-Schuckert PG VV 322/36 double-acting electric motors producing a total of Шаблон:Convert for use while submerged. She had two shafts and two Шаблон:Convert propellers. The boat was capable of operating at depths of up to Шаблон:Convert.Шаблон:Sfn

The submarine had a maximum surface speed of Шаблон:Convert and a maximum submerged speed of Шаблон:Convert.Шаблон:Sfn When submerged, the boat could operate for Шаблон:Convert at Шаблон:Convert; when surfaced, she could travel Шаблон:Convert at Шаблон:Convert. U-1 was fitted with three Шаблон:Convert torpedo tubes at the bow, five torpedoes or up to twelve Type A torpedo mines, and a [[2 cm Flak 30|Шаблон:Convert anti-aircraft gun]]. The boat had a complement of 25.Шаблон:Sfn

Service history

Her pre-war service was unremarkable, but she did gain a reputation as a poor ship. Her rapid construction, combined with the inadequacy of the technology which was used to create her, made her uncomfortable, leaky and slow. When war came, there were already plans to shelve her and her immediate sister boats for use as training boats only.

Despite this however, owing to a shortage of available units she sailed on 29 March 1940 against British shipping operating off Norway, close to the limit of her effective operating range. She failed to find a target, but was sent out again on 4 April, in preparation for Operation Weserübung (the invasion of Norway).

Fate

U-1 sent a brief radio signal on 6 April, giving her position, before she disappeared. She was struck by a mine in British minefield Field No. 7 in the North Sea north of Terschelling at position Шаблон:Coord. The entire aft section of the boat was blown off and all hands lost. In June 2007, the wreck of U-1 was located by divers.

She was the first of over 1,000 U-boats to serve during the Battle of the Atlantic, and one of over 700 to be lost at sea.
