During World War II, the Gato program, and its successor, the Balao course, carried most of the responsibility from the submarine war inside Pacific. These brand new fleet submarines had been effective vessels that became fast, strong, well armed, and worthy of the long-range patrols essential to fight toward Pacific. They waged war up against the Axis abilities, amassing accurate documentation of devastation and sheer killing power that's unrivaled by almost any land or ocean attack platform. These brand 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 help. This doctrine of forward presence and hit warfare by the submarine stays today.
