During World War II, the Gato system, and its particular successor, the Balao program, carried most of the responsibility from submarine war inside Pacific. These fresh fleet submarines was indeed effective vessels that became fast, strong, well armed, and worth the long-range patrols important to fight toward Pacific. They waged war against the Axis abilities, amassing accurate documents of devastation and sheer killing energy that is unrivaled by just about any land or ocean attack platform. These unique fleet submarines enabled the Navy to get its submarine doctrine from coastal protection to open ocean assaults on enemy warships and convoys critical to enemy logistical assistance. This doctrine of forward presence and hit warfare by the submarine remains today.
