War Plan Orange
War Plan Orange (commonly known as Plan Orange or just Orange) refers to a series of United States Joint Army and Navy Board war plans for dealing with a possible war with Japan during the years between the First and Second World Wars. It failed to foresee the significance of the technological changes to naval warfare including the submarine, air support and aircraft carriers, and although the Battle of Midway was important, and the US Navy did "island-hop" to regain lost territory, there was no culminating "showdown" battle as anticipated by Plan Orange.
