German submarine U-844
German submarine U-844 was a Type IXC/40 U-boat of Nazi Germany's Kriegsmarine, built for service during the Second World War. An extremely short-lived boat, U-844 served just ten days on her only patrol and was sunk with two other boats whilst preparing for a failed attack on a well-defended convoy within range of allied air support. Design
German Type IXC/40 submarines were slightly larger than the original Type IXCs. U-844 had a displacement of  when at the surface and  while submerged. The U-boat had a total length of , a pressure hull length of , a beam of , a height of , and a draught of . The submarine was powered by two MAN M 9 V 40/46 supercharged four-stroke, nine-cylinder diesel engines producing a total of  for use while surfaced, two Siemens-Schuckert 2 GU 345/34 double-acting electric motors producing a total of  for use while submerged. She had two shafts and two  propellers. The boat was capable of operating at depths of up to . The submarine had a maximum surface speed of  and a maximum submerged speed of . When submerged, the boat could operate for  at ; when surfaced, she could travel  at . U-844 was fitted with six  torpedo tubes (four fitted at the bow and two at the stern), 22 torpedoes, one  SK C/32 naval gun, 180 rounds, and a  SK C/30 as well as a  C/30 anti-aircraft gun. The boat had a complement of forty-eight. Service history
Built by the large DeSchiMAG AG Weser shipyards in Bremen, U-844 was rapidly completed and readied for service, her entire building program taking just under a year. Given to Oberleutnant zur See Günther Möller, she passed her initial working-up and training schedule well, and was dispatched to her first patrol in the Atlantic Ocean in the first week of October 1943 to try to stem the terrible losses being incurred by U-boats at this time. War Patrol
Ten days after her departure whilst she sailed south of Iceland she received orders to attach herself to  and  and to proceed southwards to attack Convoy ON 206 in the North Atlantic. The boats had to travel on the surface to have any hope of reaching their target, and it was this which caused disaster, as the three submarines were spotted in broad daylight by a RAF B-24 Liberator aircraft, which rapidly called allies in the form of more Liberators from 59 Squadron and 86 Squadron Royal Air Force amongst other forces. Fate
On 16 October 1943, during the day-long battle which followed, the anti-aircraft weapons of the boats were brought into use, downing two Liberators and killing a number of crewmen. It was not however enough to stave off the inevitable, and one by one the boats were separated and sunk, having been prevented from diving by constant attention from Allied aircraft. U-844 was eventually lost to a direct hit from a bomb dropped by a Liberator, the boat blowing to pieces and killing all 53 of her crew. Wolfpacks
U-844 took part in one wolfpack, namely:
 Schlieffen (16 October 1943)
