Marine One is the call sign of any United States Marine Corps aircraft carrying the President of the United States.
More than 800 Marines supervise the operation of the Marine One fleet, which is based in Quantico, Virginia, but is more often seen in action on the South Lawn of the White House or at Andrews Air Force Base in Maryland. At Andrews, it is sometimes used to connect to Air Force One for longer journeys.
