German submarine U-549 was a Type IXC/40 U-boat of Nazi Germany's Kriegsmarine during World War II. The submarine was laid down on 28 September 1942 at the Deutsche Werft yard in Hamburg, launched on 28 April 1943, and commissioned on 14 July 1943 under the command of Kapitänleutnant Detlev Krankenhagen. After training with the 4th U-boat Flotilla at Stettin, the U-boat was transferred to the 10th U-boat Flotilla for front-line service on 1 January 1944.
German Type IXC/40 submarines were slightly larger than the original Type IXCs. U-549 had a displacement of 1144t when at the surface and 1257t while submerged. The U-boat had a total length of 76.76m (251.84feet), a pressure hull length of 58.75m (192.75feet), a beam of 6.86m (22.51feet), a height of 9.6m (31.5feet), and a draught of 4.67m (15.32feet). The submarine was powered by two MAN M 9 V 40/46 supercharged four-stroke, nine-cylinder diesel engines producing a total of 4400PS for use while surfaced, two Siemens-Schuckert 2 GU 345/34 double-acting electric motors producing a total of 1000shp for use while submerged. She had two shafts and two 1.92abbr=onNaNabbr=on 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-549 was fitted with six 53.30NaN0 torpedo tubes (four fitted at the bow and two at the stern), 22 torpedoes, one 10.52NaN2 SK C/32 naval gun, 180 rounds, and a 3.7sp=usNaNsp=us SK C/30 as well as a 2sp=usNaNsp=us C/30 anti-aircraft gun. The boat had a complement of forty-eight.
U-549 departed Kiel on 11 January 1944, and sailed out into the mid-Atlantic, via the gap between Iceland and the Faroe Islands, but had no success. The U-boat arrived at Lorient in occupied France on 26 March after 76 days at sea.[1]
The U-boat left Lorient on 14 May 1944 and sailed to the waters north-west of the Canary Islands.[2] At 20:13 on 29 May 1944, U-549 slipped through the anti-submarine screen of the hunter-killer group TG 21.11, and fired three T-3 torpedoes at the escort carrier, hitting her with two, and severely damaging the ship which later sank.[3] At 20.40 hours the U-boat fired a salvo of T-5 acoustic torpedoes, badly damaging the destroyer escort, and missing the .[4] A counter-attack with depth charges was launched by and Eugene E. Elmore which sank the U-boat, in position 31.2167°N -26°W. All 57 hands were lost.
