Transportation of the President of the United States

The United States government has maintained a variety of vehicles for the President. Because of his role as Commander-in-Chief he exclusively uses military transports for international travel, however the civilian Secret Service operates the President's motorcade.

Since 1953 whenever the President is on board a military flight its call sign is the name of the armed service followed by the word "One". Thus Air Force One, Army One, Coast Guard One, Marine One and Navy One. However, only the Air Force and Marine Corps actively maintain aircraft for the Commander-in-Chief, and as of January 19, 2017^[update], the President has not flown in a Coast Guard aircraft. If the President uses a civilian airplane it is designated Executive One.

The Presidential State Car is a limousine called Cadillac One or The Beast which is operated by the Secret Service. There are at least two limousines. There is a bus unofficially called Ground Force One officially called Stagecoach, while the president is aboard, which is operated by the Secret Service.

Four Presidential Carriages were built by the H & C Studebaker blacksmith shop, the predecessor of the Studebaker Corporation; one of these carried Lincoln to the Ford's Theatre the night of his assassination. All four carriages are on permanent display at the Studebaker National Museum located in South Bend, Indiana. The carriages were used by Presidents Ulysses S. Grant, Benjamin Harrison, Abraham Lincoln and William McKinley.
