German submarine U-182

German submarine U-182 was a Type IX D 2 U-boat of Nazi Germany's Kriegsmarine which served in World War II. Her keel was laid down on 7 April 1941 at DeSchiMAG AG Weser, Bremen as yard number 1022; she was launched on 3 March 1942 and commissioned on 30 June of the same year.

She carried out a single war patrol, sinking five merchant vessels and spending 159 days at sea.

U-182 was probably sunk near Madeira on 16 May 1943 by USS MacKenzie (DD-614). 61 crew members and three prisoners of war died. The boat had been unsuccessfully attacked by a USAAF B-24 Liberator the previous day.

Design
German Type IXD2 submarines were considerably larger than the original Type IXs. U-182 had a displacement of 1610 t when at the surface and 1799 t while submerged. The U-boat had a total length of 87.58 m, a pressure hull length of 68.50 m, a beam of 7.50 m, a height of 10.20 m, and a draught of 5.35 m. The submarine was powered by two MAN M 9 V 40/46 supercharged four-stroke, nine-cylinder diesel engines plus two MWM RS34.5S six-cylinder four-stroke diesel engines for cruising, producing a total of 9000 PS for use while surfaced, two Siemens-Schuckert 2 GU 345/34 double-acting electric motors producing a total of 1000 shp for use while submerged. She had two shafts and two 1.85 m propellers. The boat was capable of operating at depths of up to 200 m.

The submarine had a maximum surface speed of 20.8 kn and a maximum submerged speed of 6.9 kn. When submerged, the boat could operate for 121 nmi at 2 kn; when surfaced, she could travel 12750 nmi at 10 kn. U-182 was fitted with six 53.3 cm torpedo tubes (four fitted at the bow and two at the stern), 24 torpedoes, one 10.5 cm SK C/32 naval gun, 150 rounds, and a 3.7 cm SK C/30 with 2575 rounds as well as two 2 cm C/30 anti-aircraft guns with 8100 rounds. The boat had a complement of fifty-five.
