German submarine U-238 was a Type VIIC U-boat of Nazi Germany's Kriegsmarine built for service in the Second World War. She was laid down on 21 April 1942, by Germaniawerft of Kiel as yard number 668, launched on 7 January 1943 and commissioned on 20 February, with Oberleutnant zur See Horst Hepp in command. Hepp commanded her for her entire career, receiving promotion to Kapitänleutnant in the process.

Design

German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-238 had a displacement of when at the surface and while submerged.Template:Sfn She had a total length of , a pressure hull length of , a beam of , a height of , and a draught of . The submarine was powered by two Germaniawerft F46 four-stroke, six-cylinder supercharged diesel engines producing a total of for use while surfaced, two AEG GU 460/8–27 double-acting electric motors producing a total of for use while submerged. She had two shafts and two propellers. The boat was capable of operating at depths of up to .Template:Sfn

The submarine had a maximum surface speed of and a maximum submerged speed of .Template:Sfn When submerged, the boat could operate for at ; when surfaced, she could travel at . U-238 was fitted with five torpedo tubes (four fitted at the bow and one at the stern), fourteen torpedoes, one SK C/35 naval gun, 220 rounds, and two twin C/30 anti-aircraft guns. The boat had a complement of between forty-four and sixty.Template:Sfn

Service history

U-238 was a member of four wolfpacks; she was a successful, if short lived boat, sinking four freighters and damaging another during her operations against Allied convoys in the Battle of the Atlantic. She had the misfortune, however, of serving at the turning point of the war, when Allied countermeasures were taking a heavy toll on the U-boat force. She conducted three war patrols, beginning in September 1943, following her warm-up trials in the Baltic Sea.

War Patrols

U-238Template:'s first patrol was conducted from Trondheim in Norway as part of the 1st U-boat Flotilla, and entailed the submarine exiting the North Sea via the Denmark Strait and operating against Allied shipping in the so-called "air cover gap" in the Central Atlantic, where Allied aircraft had insufficient range, on account of fuel limitations, to effectively operate against German U-boats. This first patrol was by far the most successful, as on 20 September 1943, the boat attacked a large convoy, sinking one 7,176 GRT cargo ship and damaging another. This was followed by three more victims on 23 September, when two Norwegian ships and a British freighter were sunk from the same convoy.

U-238Template:'s second patrol was less successful. Two weeks after leaving Brest, on the French Atlantic coast, she was attacked by a Grumman TBF Avenger torpedo bomber from the escort carrier , whose rockets killed two crew members and wounded five more, prompting the submarine to return to Brest with severe damage, which put her out of service for a month. It was during this patrol that the submarine captured two British Royal Air Force personnel whose Vickers Wellington bomber had been shot down by Template:GS.

U-238Template:'s third and last patrol began in January 1944, and lasted a fruitless month, until on 9 February, she was caught by convoy escorts of SL-147 and MKS-38 off Cape Clear. She counter-attacked, unsuccessfully, and was sunk by the sloops , and . There were no survivors.Template:Sfn

Wolfpacks

U-238 took part in four wolfpacks, namely:

• Leuthen (15 – 24 September 1943)
• Schill 2 (17 – 22 November 1943)
• Weddigen (22 November – 1 December 1943)
• Igel 2 (4 – 9 February 1944)
