The only Skipper of U-117 was KorvettenKapitän Hans-Werner Neumann. This was a big mine-laying boat, eventually converted to supporting the frontboots with fuel at sea, so she was also attached to both the 1st U-Bootflotille at Brest and the 2nd U-Bootflotille at Lorient. U-117 supplied frontboots in the North and Central Atlantic from September 1942 to May 1943; she undertook a minelaying operation at Casablanca in March 1943. One officer was accidentally killed on 8 November 1942 during a refueling operation with U-454.

On her final patrol, U-117 aborted a planned minelaying operation off New York Harbor to refuel U-66 and was subsequently lost.
