German submarine U-169 was a Type IXC/40 U-boat of Nazi Germany's Kriegsmarine built for service during World War II. Her keel was laid down on 15 May 1941 by the Deutsche Schiff- und Maschinenbau AG in Bremen as yard number 708. She was launched on 6 June 1942 and commissioned on 16 November with Oberleutnant zur See Hermann Bauer in command.

Design
German Type IXC/40 submarines were slightly larger than the original Type IXCs. U-169 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 PS 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-169 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 SK C/30 as well as a 2 cm C/30 anti-aircraft gun. The boat had a complement of forty-eight.

Service history
The U-boat's service began with training as part of the 4th U-boat Flotilla. She then moved to the 10th flotilla on 1 March 1943 for operations.

She was sunk, in position 60.9°N, -15.41667°W, on 27 March 1943 by a British B-17 Flying Fortress of No. 206 Squadron RAF piloted by Flying Officer Ian Samuel.
