German submarine U-297 was a Type VIIC/41 U-boat of Nazi Germany's Kriegsmarine during World War II.

She was laid down on 27 January 1943 by the Bremer Vulkan Werft (yard) at Bremen-Vegesack as yard number 62, launched on 9 October 1943 and commissioned on 17 November with Oberleutnant zur See Wolfgang Aldermann in command.

In one patrol, she did not sink or damage any ships.

She was sunk by a British aircraft on or after 6 December 1944. Fifty men died; there were no survivors.

Design

[edit]

German Type VIIC/41 submarines were preceded by the shorter Type VIIB submarines. U-297 had a displacement of 759 tonnes (747 long tons) when at the surface and 860 tonnes (850 long tons) while submerged.[2] 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 Germaniawerft F46 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 AEG GU 460/8–27 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).[2]

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).[2] 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-297 was fitted with five 53.3 cm (21 in) torpedo tubes (four fitted at the bow and one at the stern), fourteen torpedoes, one 8.8 cm (3.46 in) SK C/35 naval gun, (220 rounds), one 3.7 cm (1.5 in) Flak M42 and two 2 cm (0.79 in) C/30 anti-aircraft guns. The boat had a complement of between forty-four and sixty.[2]

Service history

[edit]

The boat's service life began with training with the 8th U-boat Flotilla in November 1943. She was then transferred to the 11th flotilla for operations on 1 November 1944.

She made the short journey from Kiel in Germany to Horten Naval Base in Norway, arriving on 18 November 1944.

Patrol and loss

[edit]

U-297's only patrol began from Horten; it took her through the 'gap' between the Faroe and the Shetland Islands.

She was sunk by a Sunderland flying boat of No. 201 Squadron RAF on 6 December 1944, 16 nautical miles (30 km; 18 mi) west of Yesnaby in the Orkney Islands.

Previously recorded fate and wreck discovery

[edit]

U-297 was originally thought to have been sunk on 6 December 1944 by depth charges dropped by the British frigates HMS Loch Inch and Goodall. She had also been listed as missing since 3 January 1945 probably in the Pentland Firth.

The wreck of U-297 was found and identified in May 2000. It lies at a depth of 285 ft (87 m).
