German submarine U-881 was a Type IXC/40 U-boat of Nazi Germany's Kriegsmarine during World War II. The ship was ordered on 2 April 1942, laid down on 7 August 1943, and launched on 4 March 1944. She was commissioned into the Kriegsmarine under the command of Kapitänleutnant Dr. Karl-Heinz Frischke (Crew 36) on 27 May 1944. Initially assigned to the 4th U-boat Flotilla, she was transferred to the 33rd U-boat Flotilla on 1 March 1945.

Design
German Type IXC/40 submarines were slightly larger than the original Type IXCs. U-881 had a displacement of 1144 t when at the surface and 1257 t while submerged. The U-boat had a total length of 76.76 m, a pressure hull length of 58.75 m, a beam of 6.86 m, a height of 9.60 m, and a draught of 4.67 m. The submarine was powered by two MAN M 9 V 40/46 supercharged four-stroke, nine-cylinder diesel engines producing a total of 4400 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 1.92 m propellers. The boat was capable of operating at depths of up to 230 m.

The submarine had a maximum surface speed of 18.3 kn and a maximum submerged speed of 7.3 kn. When submerged, the boat could operate for 63 nmi at 4 kn; when surfaced, she could travel 13850 nmi at 10 kn. U-881 was fitted with six 53.3 cm torpedo tubes (four fitted at the bow and two at the stern), 22 torpedoes, one 10.5 cm SK C/32 naval gun, 180 rounds, and a 3.7 cm Flak M42 as well as two twin 2 cm C/30 anti-aircraft guns. The boat had a complement of forty-eight.

Service history
For her first patrol, U-881 was assigned to operate in US coastal waters with wolfpack Seewolf. During this operation U-881 was depth charged and sunk by the American destroyer escort USS Farquhar (DE-139) on 6 May 1945 in one of the last actions in American waters of the Atlantic campaign. She sank at position 43.3°N, -47.73333°W with the loss of all 54 men on board.
