Missing since 25 August 1944 in the North Sea or Norwegian Sea. There is no explanation for its loss. 51 dead (all hands lost).
Nothing was heard from U-925 after sailing from Kristiansand on 24 August 1944 en route to the North Atlantic through the Iceland passage for weather reporting duty and the boat was subsequently posted as missing on 18 September 1944.
This boat was fitted with a Schnorchel underwater-breathing apparatus and sailed equipped with it in August 1944 but it was of course installed prior to that date.
Men lost from U-boats
Unlike many other U-boats, which during their service lost men due to accidents and various other causes, U-925 did not suffer any casualties (we know of) until the time of her loss.
U-boats Missing in Action.
