German submarine U-180 was a Type IXD1 transport U-boat of Nazi Germany's Kriegsmarine which served in World War II. Her keel was laid down on 25 February 1941 at the DeSchiMAG AG Weser yard in Bremen as yard number 1020. She was launched on 10 December 1941 and commissioned on 16 May 1942 under Fregattenkapitän Werner Musenberg (Crew 25). Stripped of torpedo armament, the Type IXD1s were designated as transport submarines, and could carry up to 252 tonnes of freight. U-180 was used primarily in clandestine operations.
German Type IXD1 submarines were considerably larger than the original Type IXs. U-180 had a displacement of 1,610 tonnes (1,580 long tons) when at the surface and 1,799 tonnes (1,771 long tons) while submerged. The U-boat had a total length of 87.58 m (287 ft 4 in), a pressure hull length of 68.50 m (224 ft 9 in), a beam of 7.50 m (24 ft 7 in), a height of 10.20 m (33 ft 6 in), and a draught of 5.35 m (17 ft 7 in). 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 9,000 metric horsepower (6,620 kW; 8,880 shp) for use while surfaced, two Siemens-Schuckert 2 GU 345/34 double-acting electric motors producing a total of 1,000 shaft horsepower (1,010 PS; 750 kW) for use while submerged. She had two shafts and two 1.90 m (6 ft) propellers. The boat was capable of operating at depths of up to 200 metres (660 ft).
The submarine had a maximum surface speed of 20.8 knots (38.5 km/h; 23.9 mph) and a maximum submerged speed of 6.9 knots (12.8 km/h; 7.9 mph). When submerged, the boat could operate for 121 nautical miles (224 km; 139 mi) at 2 knots (3.7 km/h; 2.3 mph); when surfaced, she could travel 12,750 nautical miles (23,610 km; 14,670 mi) at 10 knots (19 km/h; 12 mph). U-180 was fitted with six 53.3 cm (21 in) torpedo tubes (four fitted at the bow and two at the stern), 24 torpedoes, one 10.5 cm (4.13 in) SK C/32 naval gun, 150 rounds, and a 3.7 cm (1.5 in) with 2575 rounds as well as two 2 cm (0.79 in) anti-aircraft guns with 8100 rounds. The boat had a complement of fifty-five.
On 18 April U-180 sank the British 8,132 ton tanker Corbis about 500 nautical miles (930 km; 580 mi) east southeast of Port Elizabeth, South Africa. Three days later, on 21 April, the boat made her rendezvous with the Japanese submarine I-29, just east of Madagascar in the Indian Ocean, Subhash Chandra bose and Abid Hassan boarded I-29 and two Japanese Navy officers, both shipbuilding officers, Captains Emi Tetsushiro and Tomonaga Hideo, who were to study U-boat building techniques upon their arrival in Germany boarded U-180. Bose and Hasan's transfer is the only known record of a civilian transfer between two submarines of two different navies in World War II. Also received were two tonnes of gold ingots as payment from Japan for weapons technology.
During this voyage, U-180 was supplied by U-462 on the way to the exchange. She was supposed to be refueled by U-463 on the way back, but that boat was sunk by the British on 16 May 1943. On 19 June, U-180 was refueled by U-530.
2nd patrol and loss
Under the command of Oberleutnant zur See Rolf Riesen (Crew 38), U-180 sailed from Bordeaux on 20 August 1944 bound for Japan. She was reported sunk off the Bay of Biscay on 23 August 1944, with the loss of all of her 56 crew. The official verdict is "sunk by a mine", however, some experts speculate that trouble with the schnorkel (the underwater breathing and engine operating device), may have been the cause.

- U-180 is the subramine shown in the 2004 Bollywood film Netaji Subhas Chandra Bose: The Forgotten Hero where Netaji Subhas Chandra Bose travels with the German submarine U-180 around the Cape of Good Hope to the southeast of Madagascar, where he is transferred to the I-29 for the rest of the journey to Imperial Japan.
- U-180 is the submarine carrying Nazi party secretary, Martin Bormann, to South America in the Jack Higgins thriller, Thunder Point.
- U-180 is featured in the thriller Spook's Gold by Andrew Wood. The rendezvous on 21 April between U-180 and I-29, as well as an exchange of gold and military goods is a key element of the plot.
