German submarine U-194

German submarine U-194 was a Type IXC/40 U-boat of Nazi Germany's Kriegsmarine built during World War II for service in the Atlantic Ocean. Notable for having been fitted with the new Balkon sonar, she was a short-lived vessel, being sunk on her first and only operational war patrol.

Design

German Type IXC/40 submarines were slightly larger than the original Type IXCs. U-194 had a displacement of when at the surface and while submerged. The U-boat 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 MAN M 9 V 40/46 supercharged four-stroke, nine-cylinder diesel engines producing a total of for use while surfaced, two Siemens-Schuckert 2 GU 345/34 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.
The submarine had a maximum surface speed of and a maximum submerged speed of. When submerged, the boat could operate for at ; when surfaced, she could travel at. U-194 was fitted with six torpedo tubes, 22 torpedoes, one SK C/32 naval gun, 180 rounds, and a SK C/30 as well as a C/30 anti-aircraft gun. The boat had a complement of forty-eight.

Service history

U-194 was laid down in Bremen on 17 January 1942 and launched on 22 September. Kapitänleutnant Hermann Hesse took command upon commissioning on 8 January 1943.

''Balkon'' group listening apparatus

The passive sonar, known as Gruppenhorchgerät or GHG, fitted to early U-boats could not be used at periscope depth. To solve this, a new listening device, known as Balkon fitted to a second, lower hull, was successfully tested on U-194 in January 1943.

Loss

Twelve days into her first and only patrol, U-194 was attacked and sunk by a homing torpedo from an American Consolidated PBY Catalina aircraft of VP-84 in position. All 54 men aboard were lost. An initial post-war assessment gave credit for sinking U-194 to a British Consolidated B-24 Liberator aircraft of No. 120 Squadron RAF squadron, however this attack actually resulted in the sinking of.
