German submarine U-9 was a Type IIB U-boat of Nazi Germany's Kriegsmarine. Her keel was laid down on 8 February 1935, by Germaniawerft in Kiel as yard number 543. She was launched on 30 July 1935 and commissioned on 21 August, with Korvettenkapitän Hans-Günther Looff in command.
U-9 conducted 19 patrols under a series of commanders, including U-boat ace Wolfgang Lüth, sinking eight ships totalling 17,221 gross register tons (GRT) and damaging another displacing 412 tons. This included the French Sirène class coastal submarine Doris.
German Type IIB submarines were enlarged versions of the original Type IIs. U-9 had a displacement of 279 tonnes (275 long tons) when at the surface and 328 tonnes (323 long tons) while submerged. Officially, the standard tonnage was 250 long tons (250 t), however. The U-boat had a total length of 42.70 m (140 ft 1 in), a pressure hull length of 28.20 m (92 ft 6 in), a beam of 4.08 m (13 ft 5 in), a height of 8.60 m (28 ft 3 in), and a draught of 3.90 m (12 ft 10 in). The submarine was powered by two MWM RS 127 S four-stroke, six-cylinder diesel engines of 700 metric horsepower (510 kW; 690 shp) for cruising, two Siemens-Schuckert PG VV 322/36 double-acting electric motors producing a total of 460 metric horsepower (340 kW; 450 shp) for use while submerged. She had two shafts and two 0.85 m (3 ft) propellers. The boat was capable of operating at depths of up to 80–150 metres (260–490 ft).
The submarine had a maximum surface speed of 12 knots (22 km/h; 14 mph) and a maximum submerged speed of 7 knots (13 km/h; 8.1 mph). When submerged, the boat could operate for 35–42 nautical miles (65–78 km; 40–48 mi) at 4 knots (7.4 km/h; 4.6 mph); when surfaced, she could travel 3,800 nautical miles (7,000 km; 4,400 mi) at 8 knots (15 km/h; 9.2 mph). U-9 was fitted with three 53.3 cm (21 in) torpedo tubes at the bow, five torpedoes or up to twelve Type A torpedo mines, and a 2 cm (0.79 in) anti-aircraft gun. The boat had a complement of twenty.
U-9 was ordered on 20 July 1934, i.e. in violation of the Versailles Treaty, which denied Germany possession of submarines. The U-boat was not laid down until 11 March 1935, and launched on 29 June 1935, within weeks of the Anglo-German Naval Agreement, which granted Germany parity with the British Empire in submarines.
To serve in the 30th U-boat Flotilla, the submarine was transported in sections along the Danube to the Romanian port of Galați. She was then re-assembled by the Romanians at the Galați shipyard and sent to the Black Sea. At 10:30 on 20 August 1944, at Constanţa in Romania in position Coordinates: , U-9 was sunk by bombs from Soviet aircraft. The Soviets raised the boat and brought her into Mykolaiv in 1945. She was repaired and commissioned into the Soviet Navy as TS-16, but did not perform well and was broken up on 12 December 1946.
