Schnorchel-fitted U-boat
This boat was fitted with a Schnorchel underwater-breathing apparatus in August 1944. 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-991 did not suffer any casualties (we know of) until the time of her loss.


We have an emblem for this boat!
