 LeMay also oversaw Operation Starvation, an aerial mining operation against Japanese waterways and ports that disrupted Japanese shipping and logistics.Although his superiors were unsupportive of this naval objective, LeMay gave it a high priority by assigning the entire 313th Bombardment Wing (four groups, about 160 airplanes) to the task.Aerial mining supplemented a tight Allied submarine blockade of the home islands, drastically reducing Japan's ability to supply its overseas forces to the point that postwar analysis concluded that it could have defeated Japan on its own had it begun earlier.
