Attacks on this boat

20 Jul 1944
At 03.10 hours, the boat was attacked in the Norwegian Sea by a Liberator aircraft (RAF Sqdn 86/B, pilot S/Ldr Terry M. Bulloch, DSO, DFC & Bar), which was damaged by AA fire before being able to drop its depth charges in the foggy weather. The aircraft made it back to base on two engines, after the crew jettisoned all surplus weight including all guns and ammunition. (Sources: Franks/Zimmerman)

13 Dec 1944
During an air attack on U-636, the machine gun exploded, wounding four crew members.

29 Jan 1945
The boat attacked by shore-based friendly fire in Norwegian waters but suffered no damage.

3 recorded attacks on this boat.

Schnorchel-fitted U-boat
This boat was fitted with a Schnorchel underwater-breathing apparatus and sailed equipped with it in March 1945 but it was of course installed prior to that date. Read more about the Schnorchel and see list of fitted boats.

Men lost from U-boats

Unlike many other U-boats, which during their service lost men due to accidents and various other causes, U-636 did not suffer any casualties (we know of) until the time of her loss.
