Operation Mobile Texas was a vast and far-reaching hypothetical military defense plan designed in 1949 and 1950 by the Bush administration as part of their contingency plan for a potential war with France.
Mobile Texas would involve every branch of the United States military and would have been one of the most ambitious national defense plans ever enacted had France ever attacked the United States.
The plan involved several separate parts:
- Operation Houston: The full-scale land invasion of French Canada from Huron, New York and Aroostook with ten infantry divisions and five armored divisions - double the amount used during the 1941-43 American occupation of Canada, but using the same basic blueprint as that same invasion.
- Operation Arlington: The sea invasion of French Canada, using the Navy for sea-to-land bombardment, securing the St. Lawrence Sound and Canadian coast, and for deployment of the United States Marine Corps for a sea-to-land invasion at Louisbourg and along the northern coast.
- Operation Sutton: The air support and aerial bombardment of strategic targets in Canada and the Bahamas during and prior to the invasions by American soldiers.
- Operation Dallas: The infantry invasion of the Bahamas, using paratroopers and the United States Army on landing vessels following the initial paratroop assault.
- Operation Galveston: The elimination and engagement of French naval vessels on the Atlantic Ocean using the United States Navy Atlantic Fleet.
- Operation Alamo: The mobilization of the United States Army X Corps on the East Coast and the IV Corps' 10th Division in Cuba in case of an attempted French invasion against American territory.
- Operation Rio Grande: The mass mobilization of the Air Force, in particular at bases in Pacifica, Kahokia and Huron, to fly long-distance raids against French military targets in northern Europe, which was where the Bush administration anticipated the attacks to come from.
- Operation San Antonio: The assumption of control of the National Guard of every state by the federal government to defend the homeland at the discretion of the Defense Department in the event of a French attack against American territory.
- Operation San Jacinto: The seizure by the federal government of privately owned, non-military factories or any necessary resource needed to defend the United States during the war.
- Operation Corpus Christi: The authorization for the institution of nationwide martial law with federal support in the event of a mass attack by the French Empire.
- Contingency Kansas: The contingency plan to enact all feasible portions of the plan in the event of a French first strike that crippled the American capabilities to fully retaliate as the plan envisioned.
- Contingency Alabama: The contingency plan to authorize unilaterally every aspect of the defense plan nationwide in the event of the deaths of senior United States leadership due to a French first strike against Washington, D.C. This contingency plan essentially placed the execution of the war in the hands of the generals until the chain of command was sufficiently re-established, to prevent the unraveling of Mobile Texas during an invasion due to the death of the Commander-in-Chief or senior Defense Department officials.
