Transportation of the president of the United States

The United States government has maintained a variety of vehicles for the president. Because of the president's role as commander-in-chief, military transports are exclusively used for international travel; however, the civilian Secret Service operates the president's motorcade.

One of the most famous transports is "Air Force One", which is not technically a specific aircraft, but rather the callsign of certain aircraft when the president is on board. This practice was started when there was confusion between the presidential aircraft and a civilian aircraft in 1953. However, it usually means the VC-25, a Boeing 747 which has been converted for presidential use. Presidents have traveled in everything from horses, trains, cars, helicopters, boats, and fixed-wing aircraft.
