U-745 was a Type VIIC U-Boat built for Nazi Germany's Kriegsmarine for service during World War II, and which was lost at sea on 30 January 1945.

U-745 was launched on 16 April 1943, under the command of Wilhelm von Trotha, who would remain its commanding officer for its entire service. U-745 had a crew of 45.

Service History[edit]

She undertook four patrols during her service, and sank one allied auxiliary ship (the Soviet minesweeping trawler T-45 Antikajnen (No 48) and one allied warship (the Soviet fleet minesweeper T-76 Korall).

Fate[edit]

On 30 January 1945, she was lost with all hands in the Gulf of Finland, possibly having struck a German mine although it is also believed that it was sunk by a mine laid by the Finnish Minelayer Louhi.

Wilhelm von Trotha's body was later found near Foglo, Finland, and was buried three days later. No other bodies were recovered. Unlike most U-Boats, which suffered casualties during the course of service due to accidents or other causes, U-745 suffered no casualties at all, until the time of her disappearance.
