German submarine U-215 was a Type VIID mine-laying U-boat of Nazi Germany's Kriegsmarine during World War II. She was one of six U-boats of her kind, equipped with special vertical tubes that launched the mines.[4] Its keel was laid down 15 November 1940 by Germaniawerft in Kiel as yard number 647. It was launched on 9 October 1941 and commissioned on 22 November with Kapitänleutnant Fritz Hoeckner in command.

Design

As one of the six German Type VIID submarines, U-215 had a displacement of 965 tonnes (950 long tons) when at the surface and 1,080 tonnes (1,060 long tons) while submerged.[5] It had a total length of 76.90 m (252 ft 4 in), a pressure hull length of 59.80 m (196 ft 2 in), a beam of 6.38 m (20 ft 11 in), a height of 9.70 m (31 ft 10 in), and a draught of 5.01 m (16 ft 5 in). The submarine was powered by two Germaniawerft F46 supercharged four-stroke, six-cylinder 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 460/8-276 double-acting electric motors producing a total of 750 shaft horsepower (760 PS; 560 kW) for use while submerged. It had two shafts and two 1.23 m (4 ft) propellers. It was capable of operating at depths of up to 230 metres (750 ft).[5]

The submarine had a maximum surface speed of 16–16.7 knots (29.6–30.9 km/h; 18.4–19.2 mph) and a maximum submerged speed of 7.3 knots (13.5 km/h; 8.4 mph).[5] When submerged, it could operate for 69 nautical miles (128 km; 79 mi) at 4 knots (7.4 km/h; 4.6 mph); when surfaced, it could travel 11,200 nautical miles (20,700 km; 12,900 mi) at 10 knots (19 km/h; 12 mph). U-215 was fitted with five 53.3 cm (21 in) torpedo tubes (four fitted at its bow and one at its stern), twelve torpedoes, one 8.8 cm (3.46 in) SK C/35 naval gun, 220 rounds, and an anti-aircraft gun. It had a complement of between forty-four.[6]

Service history

U-215 was sunk in the summer of 1942 by British warship HMS Le Tiger while on a mission to lay mines in Boston Harbor after attacking and sinking the U.S. liberty ship Alexander Macomb, part of an allied convoy. The wreck was not discovered until 2004.[7]

Wreck Site

She now lays 270 feet (82 m) beneath the surface of the Atlantic, 150 nautical miles (280 km; 170 mi) off the coast of New England and south of Nova Scotia, just across international waters into Canadian territory. 4 of her 5 vertical tubes are still sealed, her hatches are still sealed, and she is (presumably) still airtight with the remains of 49 German sailors entombed within.[8]
