German submarine U-80 was a Type VIIC submarine of Nazi Germany's Kriegsmarine during World War II. She was laid down at the Bremer Vulkan Vegesacker Werft in Bremen as yard number 8 on 17 April 1940, launched on 11 February 1941 and commissioned on 8 April under Oberleutnant zur See Georg Staats.
U-80 spent her career as a training boat, first with the 1st U-boat Flotilla, then the 26th, 24th, 23rd and 21st flotillas. She sank or damaged no ships, but was herself sunk in a diving accident west of Pillau (now Baltiysk in modern Russia), on 28 November 1944.
German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-80 had a displacement of 769 tonnes (757 long tons) when at the surface and 871 tonnes (857 long tons) while submerged. She had a total length of 67.10 m (220 ft 2 in), a pressure hull length of 50.50 m (165 ft 8 in), a beam of 6.20 m (20 ft 4 in), a height of 9.60 m (31 ft 6 in), and a draught of 4.74 m (15 ft 7 in). The submarine was powered by two MAN M6V 40/46 four-stroke, six-cylinder supercharged diesel engines producing a total of 2,800 to 3,200 metric horsepower (2,060 to 2,350 kW; 2,760 to 3,160 shp) for use while surfaced, two Brown, Boveri & Cie GG UB 720/8 double-acting electric motors producing a total of 750 metric horsepower (550 kW; 740 shp) for use while submerged. She had two shafts and two 1.23 m (4 ft) propellers. The boat was capable of operating at depths of up to 230 metres (750 ft).
The submarine had a maximum surface speed of 17.7 knots (32.8 km/h; 20.4 mph) and a maximum submerged speed of 7.6 knots (14.1 km/h; 8.7 mph). When submerged, the boat could operate for 80 nautical miles (150 km; 92 mi) at 4 knots (7.4 km/h; 4.6 mph); when surfaced, she could travel 8,500 nautical miles (15,700 km; 9,800 mi) at 10 knots (19 km/h; 12 mph). U-80 was fitted with two 53.3 cm (21 in) torpedo tubes at the bow, fourteen torpedoes, one 8.8 cm (3.46 in) SK C/35 naval gun, 220 rounds, and a 2 cm (0.79 in) C/30 anti-aircraft gun. The boat had a complement of between forty-four and sixty.
