German submarine U-133 (1941)


German submarine U-133 was a Type VIIC U-boat built for Nazi Germany's Kriegsmarine for service during World War II. She was laid down on 10 August 1940 by Vegesacker Werft, Bremen-Vegesack as yard number 12, launched on 28 April 1941 and commissioned on 5 July that year. U-133 sank with all hands lost after striking a mine off Aegina island Greece on 14 March 1942. In 1986 the professional divers Efstáthios "Státhis" Baramátis and Theófilos Klímis located an unknown wreck at a depth of 74 meters that identified as a German submarine due to the compass of the vessel. Almost ten years later, in the mid-90s, the same wreck was further identified by Greek divers as the U-133.
