Technical specifications
The Kriegsmarinewerft Wilhelmshaven (formerly Kaiserliche Werft Wilhelmshaven ) was mainly commissioned to equip warships and from 1942 was also included in the German submarine building program. The shipyard was intended for an annual output of 12 boats. This production goal was never achieved. The Kriegsmarinewerft delivered a total of 27 Type VII C boats to the Kriegsmarine by 1945.
As a VII C-boat, U 774 also had a water displacement of 769 t on the surface and 871 t under water. It was a total of 67.1 m long, 6.2 m wide, 9.6 m high with a 50.5 m long pressure hull and had a draft of 4.74 m. The submarine was powered by two four-stroke F46 diesel engines, each with 6 cylinders and a charge fan from the Kiel Germania shipyard with an output of 2060 to 2350 kW, and two electric motors GU 460 / 8-27 from AEG with an output of 550 kW for underwater operation . It had two drive shafts with two 1.23 m tall propellers. The boat was suitable for diving to a depth of 230 m.
