The Boeing VC-25 is a military version of the Boeing 747 airliner, modified for presidential transport and operated by the United States Air Force as Air Force One, the call sign of any U.S. Air Force aircraft carrying the President of the United States.
Only two examples of this aircraft type are in service; they are highly modified Boeing 747-200Bs, designated VC-25A and having tail numbers 28000 and 29000. Although technically the Air Force One designation applies to the aircraft only while the President is on board, the term is commonly used to refer to the VC-25 in general. The two aircraft often operate in conjunction with Marine One helicopters, which ferry the President to airports whenever a vehicle motorcade would be inappropriate. Two new aircraft, designated VC-25B and based on the Boeing 747-8, have been ordered by the USAF.
Marine One is the call sign of any United States Marine Corps aircraft carrying the president of the United States. It usually denotes a helicopter operated by Marine Helicopter Squadron One (HMX-1) "Nighthawks", consisting of either the large Sikorsky VH-3D Sea King or the newer, smaller VH-60N "White Hawk". Both helicopters are called "White Tops" because of their livery. Any Marine Corps aircraft carrying the vice president has the call sign Marine Two.
