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-1023 did not suffer any casualties (we know of) until the time of her loss.
