German submarine U-228

German submarine U-228 was a Type VIIC U-boat built for the Nazi German Kriegsmarine for service during World War II.

Built at the Friedrich Krupp Germaniawerft shipyard in Kiel, the U-boat was laid down on 18 October 1941, launched on 30 July 1942 and commissioned on 12 September 1942. U-228 served with the 5th U-boat Flotilla for training, and later with the 6th U-boat Flotilla from 1 March 1943 to 5 October 1944 as a front-line boat.

U-228 completed six patrols without sinking any ships, but shot down two aircraft. She was damaged at Bergen, Norway, struck on 5 October 1944 and later broken up.
