German submarine U-45 was a Type VIIB U-boat of Nazi Germany's Kriegsmarine during World War II. She was ordered on 21 November 1936 and laid down on 23 February 1937 at F. Krupp Germaniawerft AG in Kiel as yard number 580. She was launched on 27 April 1938 and commissioned on 25 June 1938 under the command of Kapitänleutnant (Kptlt.) Alexander Gelhaar.
During her Kriegsmarine service, U-45 conducted only two war patrols and sank two vessels for a loss of 19,313 gross register tons (GRT).
While operating with others in an attack on an Allied convoy, U-45 was sunk by depth charges from the British destroyers HMS Inglefield, Ivanhoe and Intrepid on 14 October 1939 southwest of Ireland.
First war patrol
Her training exercises completed, U-45 left Kiel on her first war patrol on 19 August 1939 (prior to the outbreak of World War II) under the command of Kptlt. Alexander Gelhaar. During 28 days at sea no enemy vessels were attacked and the submarine returned to her base at Kiel on 15 September 1939.
Second war patrol
Sailing again on 9 October 1939 under the command of Kptlt. Alexander Gelhaar, U-45 began her second and final war patrol. On 14 October, the U-boat sighted and attacked convoy KJF-3 about 230 nautical miles (430 km; 260 mi) southwest of Ireland. This attack yielded the only two successes by U-45, the 9,205 British freighter Lochavon and the 10,108 French merchant ship Bretagne. U-45 also attacked but failed to damage the 10,350 ton British steam merchantman Karamea; the single torpedo fired at this ship detonated prematurely (a common problem early in the war). Survivors of this attack were picked up by HMS Ilex and landed at Plymouth.
