German submarine U-385

German submarine U-385 was a Type VIIC U-boat of Nazi Germany's Kriegsmarine during World War II.

She carried out two patrols. She did not sink or damage any ships.

She was sunk by a British warship and an Australian aircraft in the Bay of Biscay on 11 August 1944.

Design
German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-385 had a displacement of 769 t when at the surface and 871 t while submerged. She had a total length of 67.10 m, a pressure hull length of 50.50 m, a beam of 6.20 m, a height of 9.60 m, and a draught of 4.74 m. The submarine was powered by two Germaniawerft F46 four-stroke, six-cylinder supercharged diesel engines producing a total of 2800 to 3200 PS for use while surfaced, two Garbe, Lahmeyer & Co. RP 137/c double-acting electric motors producing a total of 750 PS for use while submerged. She had two shafts and two 1.23 m propellers. The boat was capable of operating at depths of up to 230 m.

The submarine had a maximum surface speed of 17.7 kn and a maximum submerged speed of 7.6 kn. When submerged, the boat could operate for 80 nmi at 4 kn; when surfaced, she could travel 8500 nmi at 10 kn. U-385 was fitted with five 53.3 cm torpedo tubes (four fitted at the bow and one at the stern), fourteen torpedoes, one 8.8 cm SK C/35 naval gun, 220 rounds, and two twin 2 cm C/30 anti-aircraft guns. The boat had a complement of between forty-four and sixty.

Service history
The submarine was laid down on 16 May 1941 at the Howaldtswerke yard at Kiel as yard number 16, launched on 8 July 1942 and commissioned on 29 August under the command of Kapitänleutnant Hans-Guido Valenter.

She served with the 5th U-boat Flotilla from 29 August 1942 and the 6th flotilla from 1 March 1944.

The boat was moved from Kiel to Marviken in March 1944.

First patrol
U-385's first patrol took her from Marviken to St. Nazaire, in occupied France via the gap between Iceland and the Faroe Islands.

Second patrol and loss
The boat left St. Nazaire on 9 August 1944. On the 11th, whilst still in the Bay of Biscay, she was sunk by depth charges dropped by an Australian Sunderland flying boat of No. 461 Squadron RAAF (captained by pilot officer Ivan Southall) and the British sloop HMS Starling (U66) captained by Cdr. NW Duck.

One man died in the U-boat; there were 42 survivors.
