U 670 was a German type VII C submarine. This type was also called "Atlantic boat". The boat was intended to be used by the German Navy during World War II in the submarine warfare , but sank before it could be used.
Technical specifications
After the start of the war, the Howaldtswerke shipyard in Hamburg switched its production entirely to submarine construction. An annual output of 16 submarines was planned, which should increase to 22 boats from mid-1943. However, these numbers could never be reached. One of the ten boats that were delivered in 1942 was the U 670 . It was 67 m long and had a displacement of 865 m³ under water. It was propelled over water by two diesel engines, which enabled a speed of 17 knots . Two electric motors produced a speed of 7 knots under water. The armament consisted of a 8.8 cm cannon and a 2.0 cm flak on deck as well as four bow torpedo tubes and a stern torpedo tube.
history
After commissioning, the U 670 was transferred from Hamburg through the Kiel Canal to Kiel , the base of the 5th U-Flotilla , to which the boat was placed as a training boat. This was followed by test drives and then training drives in the Baltic Sea to bring the boat in and train the crew.
Downfall
The boat collided on August 20, 1943 at 11:30 p.m. in the Bay of Danzig with the Bolkoburg , a target ship that was used for target practice. 21 men from U 670 were killed, 22 crew members survived the sinking of the boat.
One of the survivors was Commander Oberleutnant zur See Hyronimus. He put U 678 into service in October 1943 , with which he was sunk on July 6, 1944 in the English Channel off Brighton .
