Air Force One is the official call sign for any Air Force aircraft carrying the President of the United States, though the term most commonly refers to the two Boeing 747 jets bearing the iconic Water and Steel Blue livery.

The Boeing 747 Air Force One, houses an executive suite and private office for the President, as well as a medical annex and communications room featuring at least 19 televisions and 87 telephones. The plane can fuel in midair, contains countermeasures against anti-aircraft missiles and features special shielding to protect the electronics from an electromagnetic pulse resulting from a nuclear attack.
