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. Informal studies as early as 1906 covered a number of possibilities, from basing at Gibraltar or Singapore (an idea revived by the British before World War II) to "a quick trans-Atlantic dash" to the Pacific. The plan eventually adopted was conceived by Rear Admiral Raymond P. Rodgers in 1911.
