Design

German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-973 had a displacement of 769 tonnes (757 long tons) when at the surface and 871 tonnes (857 long tons) while submerged.[1] It 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 Brown, Boveri & Cie GG UB 720/8 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).[1]

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).[1] When submerged, it could operate for 80 nautical miles (150 km; 92 mi) at 4 knots (7.4 km/h; 4.6 mph); when surfaced, it could travel 8,500 nautical miles (15,700 km; 9,800 mi) at 10 knots (19 km/h; 12 mph). U-973 was fitted with five 53.3 cm (21 in) torpedo tubes (four fitted at its bow and one at its stern), fourteen 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 and sixty.[1]

Fate

On the 6 March 1944 U-973 was sighted by Fairey Swordfish 816/'X' operating from the British escort carrier HMS Chaser, crewed by Sub-Lt(A) Bennett, Sub-Lt(A) Horsfield and PO Vines. Chaser was escorting convoys through Arctic waters. As they approached the submarine began firing with four 20 mm guns. Bennett fired three pairs of rockets, one of which struck the submarine just below the conning tower. The attack left 51 dead and 15 survivors.

Wolfpacks

U-973 took part in three wolfpacks, namely.

  • Werwolf (4–11 February 1944)
  • Boreas (2–5 March 1944)
  • Taifun (5–6 March 1944)
