The Gato-class of submarine was the state of the art in American design at the start of World War II. Using the previous Tambor-class submarine as the model standard, the Gatos incorporated improvements that increased their overall patrolling and combat abilities. Modifications to the diesel engines and batteries increased patrol duration over that of the Tambors, and internal alterations provided more amenities for the crew.

Several Gato subs are on display in the United States. For instance, the USS Cobia (SS-245) is at the Wisconsin Maritime Museum. See their web site for details: http://www.wimaritimemuseum.org/sub.htm
