German submarine U-122 was a Type IXB U-boat of Nazi Germany's Kriegsmarine that operated during World War II.
She was ordered on 15 December 1937 and was laid down on 5 March 1939 at
Design
The submarine had a maximum surface speed of 18.2 knots (33.7 km/h; 20.9 mph) and a maximum submerged speed of 7.3 knots (13.5 km/h; 8.4 mph).
Service history
She carried out two combat patrols with the 2nd U-boat Flotilla. On her first foray in May 1940, she transported an 88 mm Flak (anti-aircraft gun) with ammunition, some bombs, 90 cbm (some 750 barrels (119 m3)) of fuel for aircraft and some motor oil to Trondheim during the Norwegian campaign. On 23 May she encountered an enemy submarine in the North Atlantic, but neither boat attacked each other.[3] She sank a single ship during her career, the SS Empire Conveyor (5911 GRT) on 20 June 1940.[4]
She was declared missing with all hands after 22 June 1940 between the North Sea and the Bay of Biscay. She may have collided with the vessel San Felipe on 22 June, or been sunk by depth charges from the corvette HMS Arabis on 23 June.
Some Dutch and Polish authors suggest that U-122 was sunk after being rammed by the submarine ORP Wilk on 20 June soon after midnight.[5][4] The first officer of Wilk reported in his memoirs ramming a surfaced U-boat while it was attempting to dive. This version was often disputed and an alternative theory states that Wilk instead rammed and sank the Dutch submarine O-13, or most probably, a minefield protector buoy rather than a submarine.[4] Moreover, the U-122 sank the SS Empire Conveyor during the day following the Wilk's collision, and she was too far away then, and reported her position for the last time on 21 June.[4]
