'''German submarine ''U-845''''' was a [[German Type IX submarine|Type IXC/40]] [[U-boat]] built for [[Nazi Germany]]'s ''[[Kriegsmarine]]'' during [[World War II]].

==Design==
[[German Type IX submarine#Type IXC/40|German Type IXC/40 submarines]] were slightly larger than the original [[German Type IX submarine#Type IXC|Type IXC]]s. ''U-845'' had a displacement of {{convert|1144|t|LT}} when at the surface and {{convert|1257|t|LT}} while submerged.{{sfn|Gröner|1991|p=68}} The U-boat had a total length of {{convert|76.76|m|ftin|abbr=on}}, a [[pressure hull]] length of {{convert|58.75|m|ftin|abbr=on}}, a [[beam (nautical)|beam]] of {{convert|6.86|m|ftin|abbr=on}}, a height of {{convert|9.60|m|ftin|abbr=on}}, and a [[draught (ship)|draught]] of {{convert|4.67|m|ftin|abbr=on}}. The submarine was powered by two [[MAN SE|MAN]] M 9 V 40/46 [[supercharged]] four-stroke, nine-cylinder [[diesel engine]]s producing a total of {{convert|4400|PS|kW shp|-1}} for use while surfaced, two [[Siemens-Schuckert]] 2 GU 345/34 [[Motor–generator|double-acting electric motors]] producing a total of {{convert|1000|shp|PS kW|-1}} for use while submerged. She had two shafts and two {{convert|1.92|m|ft|abbr=on|0}} [[propeller]]s. The boat was capable of operating at depths of up to {{convert|230|m}}.{{sfn|Gröner|1991|p=68}}

The submarine had a maximum surface speed of {{convert|18.3|kn}} and a maximum submerged speed of {{convert|7.3|kn}}.{{sfn|Gröner|1991|p=68}} When submerged, the boat could operate for {{convert|63|nmi}} at {{convert|4|kn}}; when surfaced, she could travel {{convert|13850|nmi}} at {{convert|10|kn}}. ''U-845'' was fitted with six {{convert|53.3|cm|in|0|abbr=on}} [[torpedo tube]]s (four fitted at the bow and two at the stern), 22 [[torpedo]]es, one [[10.5 cm SK C/32 naval gun|{{convert|10.5|cm|in|2|abbr=on}} SK C/32 naval gun]], 180 rounds, and a [[3.7 cm SK C/30|{{convert|3.7|cm|in|sp=us|abbr=on}} SK C/30]] as well as a [[2 cm FlaK 30|{{convert|2|cm|in|sp=us|abbr=on}} C/30]] anti-aircraft gun. The boat had a [[Ship's company|complement]] of forty-eight.{{sfn|Gröner|1991|p=68}}

==Service history==
''U-845'' was ordered on 20 January 1941 from [[DeSchiMAG]] [[AG Weser]] in [[Bremen]] under the [[yard number]] 1051. Her keel was [[Keel laying|laid down]] on 20 June 1942. The U-boat was [[Ceremonial ship launching|launched]] the following year on 18 January 1943. she was [[Ship commissioning|commissioned]] into service under the command of ''[[Kapitänleutnant]]'' Udo Behrens (Crew 30) in [[4th U-boat Flotilla]] on 1 May 1943.

On 3 July 1943, ''Kapitänleutnant'' Rudolf Hoffmann (Crew 36) took over command. On her way to [[Gotenhafen]] ''U-845'' assisted {{GS|U-490||2}} which was unable to dive and escorted her to port where they arrived on 24 July. Hoffmann handed over command to ''[[Korvettenkapitän]]'' Werner Weber (Crew 25) on 8 October 1943. On 1 January 1944 ''U-845'', which had been transferred to the [[10th U-boat Flotilla]], left for operations in the North Atlantic. Via [[Kristiansand]], [[Stavanger]] and [[Bergen]] she reached her assigned operation area off [[Newfoundland]] in February 1944. A first attack on an unescorted freighter on 6 February 1944 failed, but three days later a British steamer, {{SS|Kelmscott||2}} ({{GRT|7039|link=off}}), fell victim to ''U-845''{{'}}s torpedo. On 14 February the U-boat was spotted by an aircraft. In the subsequent attack one crew member died and two others were wounded. An attack on another unescorted freighter the next day failed to sink the ship. On 10 March 1944, ''U-845'' made contact with [[convoy SC 154]], but was picked up by an escort, {{HMCS|St. Laurent|H83|6}}, in the late afternoon and depth-charged. When the U-boat surfaced late at night, she was attacked by ''St. Laurent'' and three other escorts of 9th Escort Group, {{HMCS|Swansea|K328|6}}, {{HMCS|Owen Sound}} and {{HMS|Forester|H74|6}}, with artillery, killing Weber and the bridge crew as well as the crew servicing the AA guns. The rest of the crew survived the attack and was picked up by the escorts. ''Swansea'' picked up 23, ''Forester'' 17, and ''St. Laurent'' five men.{{sfn|Busch|Röll|1999|p=203-4}}
