German submarine U-1225 was a Type IXC/40 U-boat of Nazi Germany's Kriegsmarine during World War II.

The submarine was laid down on 28 December 1942 at the Deutsche Werft yard at Hamburg, launched on 21 July 1943, and commissioned on 10 November 1943 under the command of Oberleutnant zur See Ernst Sauerberg. The U-boat then served with 31st U-boat Flotilla, a training unit, until 31 May 1944. She was then transferred to the 2nd U-boat Flotilla for active service.[1]

Service History[edit]

U-1225 had a short and tragic active career. She departed Kristiansand on 20 June 1944, never to return. Four days out of port, the new submarine was attacked by Canso aircraft of No. 162 Squadron RCAF. The flying boat was shot down, but not before her depth charges fatally wounded the U-boat. All 56 sailors went down with the sub. Three of the eight aircrew from the Catalina were lost as well.[3]
