German submarine U-378 was a Type VIIC U-boat of Nazi Germany's Kriegsmarine during World War II.
She carried out eight patrols before being sunk by US aircraft on 20 October 1943 in mid-Atlantic at position 47°40′N 28°27′W / 47.667°N 28.450°WCoordinates: 47°40′N 28°27′W / 47.667°N 28.450°W.
She was a member of 16 wolfpacks.
She sank one warship.
Design
German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-378 had a displacement of 769 tonnes (757 long tons) when at the surface and 871 tonnes (857 long tons) while submerged.[4] 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 Garbe, Lahmeyer & Co. RP 137/c 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).[4]
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).[4] 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-378 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, and an anti-aircraft gun. The boat had a complement of between forty-four and sixty.[4]
Service history
The submarine was laid down on 3 May 1940 at the Howaldtswerke yard at Kiel as yard number 9, launched on 13 September 1941 and commissioned on 30 October under the command of Kapitänleutnant Alfred Hoschatt.
1st patrol
The boat's first patrol was in two parts and commenced with her departure from Kiel on 11 March 1942. The second part began from the German island of Helgoland (sometimes spelt 'Heligoland'). She was attacked northeast of Norway's North Cape by the British destroyer HMS Fury. No damage was sustained.
2nd - 6th patrols
U-378 continued to operate in northern waters such as the Barents, Greenland and Norwegian seas until April 1943 when her sphere of operations changed to the Atlantic Ocean.
7th patrol
This sortie saw the boat leave Trondheim on 12 April 1943, negotiate the gap separating Iceland and the Faroe Islands and sail as far eastward as Newfoundland and Labrador. She then re-crossed the Atlantic, docking at La Pallice in occupied France on 4 June. At 54 days, this was easily the submarine's longest patrol.
8th patrol and loss
U-378 sank the Polish destroyer Orkan on 8 October 1943. The Commander, ten officers, 166 ratings and seven British crew members were lost.
On the 13th, the boat was the target of a FIDO homing torpedo that had been dropped from a TBF Avenger, but the weapon missed.
The submarine was sunk by an Avenger / F4F Wildcat pair on 20 October in mid-Atlantic. The aircraft had flown from USS Core.
48 men died in the depth charge attack; there were no survivors.
Wolfpacks
U-378 took part in 16 wolfpacks, namely.
- Ziethen (23–29 March 1942)
- Eiswolf (29–31 March 1942)
- Robbenschlag (7–14 April 1942)

- Strauchritter (29 April – 5 May 1942)
- Trägertod (19–22 September 1942)
- Boreas (19 November – 9 December 1942)
- Eisbär (27–30 March 1943)
- Meise (25–27 April 1943)
- Star (27 April – 4 May 1943)
- Fink (4–6 May 1943)
- Naab (12–15 May 1943)
- Donau 2 (15–19 May 1943)
- Mosel (19–24 May 1943)
