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 completed on 29 June 1935 after a very rapid construction, and was manned by crews trained in the Netherlands.
German Type II submarines were based on the Finnish submarine Vesikko. U-1 had a displacement of 254 tonnes (250 long tons) when at the surface and 303 tonnes (298 long tons) while submerged. Officially, the standard tonnage was 250 long tons (250 t), however. The U-boat had a total length of 40.90 m (134 ft 2 in), a pressure hull length of 27.80 m (91 ft 2 in), a beam of 4.08 m (13 ft 5 in), a height of 8.60 m (28 ft 3 in), and a draught of 3.83 m (12 ft 7 in). The submarine was powered by two MWM RS 127 S four-stroke, six-cylinder diesel engines of 700 metric horsepower (510 kW; 690 shp) for cruising, two Siemens-Schuckert PG VV 322/36 double-acting electric motors producing a total of 360 metric horsepower (260 kW; 360 shp) for use while submerged. She had two shafts and two 0.85 m (3 ft) propellers. The boat was capable of operating at depths of up to 80–150 metres (260–490 ft).
Monday morning
Eighteen years of dawning
I say how long
You say how long
It was one dull morning
Woke the world with bawling
I was so sad (so sad)
It was so bad
I was of a feeling it was out of control
I had the opinion it was out of control
Boys and Girls
Go to the school and girls
They make children
Not like this one
I was of a feeling it was out of control
I had the opinion it was out of control
I was of a feeling it was out of control
I had the opinion it was out of control
(Out of control)
I fought fate
There's blood on the garden gate
The man said childhood
It's in his childhood
One day I'll die
The choice will not be mine
Will it be too late
You can't fight it
I was of a feeling it was out of control
