During World War II, the Gato course, and its particular successor, the Balao class, carried a lot of the responsibility from the submarine war inside Pacific. These new fleet submarines was effective vessels that became fast, strong, well armed, and worthy of the long-range patrols essential to fight to the Pacific. They waged war up against the Axis abilities, amassing accurate documentation of devastation and sheer killing power that is unrivaled by virtually any land or ocean attack platform. These new fleet submarines enabled the Navy to go its submarine doctrine from coastal defense to open ocean assaults on enemy warships and convoys critical to enemy logistical support. This doctrine of forward presence and hit warfare by the submarine remains today.
