<P> Air Force Two is the air traffic control call sign held by any United States Air Force aircraft carrying the U.S. Vice President, but not the President . The term is often associated with the Boeing C - 32, a modified 757 which is most commonly used as the Vice President's transport . Other 89th Airlift Wing aircraft, such as the Boeing C - 40 Clipper, C - 20B, C - 37A, and C - 37B have served in this role as well . The VC - 25A, the aircraft most often used by the President as Air Force One, has also been used by the vice president as Air Force Two . </P> <P> Although the U.S. Marine Corps carries the primary mission for helicopter support of both the president (Marine One) and vice president (Marine Two), UH - 1N Twin Huey helicopters from the Air Force's 1st Helicopter Squadron are also used to support the Vice President in the Washington, D.C. area under the call sign Air Force Two . </P>
