General notes on this boat
2 Apr 1945. On 2 April, 1945 U-1109 had to return to base due to technical problems.
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-1109 did not suffer any casualties (we know of) until the time of her loss.
