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.

Design[edit]

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.[1] 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).[1]

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).[1] 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.[1]

Service history[edit]

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.

Fate[edit]

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.[2] At 10:30 on 20 August 1944, at Constanţa in Romania in position 44°12′N 28°41′E / 44.200°N 28.683°E / 44.200; 28.683Coordinates: 44°12′N 28°41′E / 44.200°N 28.683°E / 44.200; 28.683, 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.
