The Boeing C-32 is a military passenger transport of the United States Air Force, providing transportation for United States leaders to locations around the world. The primary users are the Vice President of the United States (using the distinctive call sign "Air Force Two"), the First Lady, and the Secretary of State. On rare occasions, other members of the U.S. Cabinet and Congressional leaders have been authorized to fly aboard the C-32 for various missions. The C-32, since its debut, has also served as Air Force One in place of the larger VC-25A to airports that cannot accommodate the Boeing 747-based "jumbo" jet.
The C-32 is a Boeing 757-200, a mid-size, narrow-body twin-engine jet airliner—that has been modified for government use, mainly a change to a 45-passenger interior and military avionics.
A contract was awarded in August 1996 for four aircraft supplemented by the smaller C-37A to replace the aging fleet of VC-137 aircraft. The first aircraft was delivered to the 89th Airlift Wing at Andrews Air Force Base, Maryland in late June 1998.
Two further second-hand Boeing 757s were acquired in 2010 for government use although it is not clear which agency they are operated by; they have been frequently associated with the Foreign Emergency Support Team of the U.S. State Department.
The additional two aircraft, designated C-32B, have been modified with aerial refueling equipment and extended range fuel cells giving them a 6,000 nmi (6,900 mi; 11,000 km) range.
The four C-32As are operated by the 1st Airlift Squadron of the 89th Airlift Wing. They are available for use by the vice-president (using call sign Air Force Two), the first lady and members of the cabinet and congress. They are also used by the President (using call sign Air Force One) if the destination is too small to take the larger VC-25.
