All of the "Gato"s (with one exception, ) would eventually fight in the Pacific Theater of Operations. However, in the summer of 1942, six new "Gato"s were assigned to Submarine Squadron 50 and sent to Rosneath, Scotland, to patrol the Bay of Biscay and to assist in the Operation Torch landings in North Africa. All in all, they conducted 27 war patrols, but could not claim any verified sinkings. Considered a waste of valuable resources, in mid-1943, all six boats were recalled and transferred to the Pacific.
