The Boeing C-137 is a military version of the Boeing 707 which was used by the USAF. Air Force One is the air traffic control call sign of any U.S. Air Force aircraft carrying the President of the United States.

In 1959, the time when the Boeing 707 was very limited, it incorporated four 6123-kg (13,500 lb.) dry thrust Pratt & Whitney JT3C6 turbojets but only one variant had served eith the USAF, the VC-137C Air Force One Presidential transport. To supplement the VC-137s, C-135 airframes were converted by the USAF to VC-135 VIP standard. The primary users of these were the United States, wherein they used it for staff transport.

VC-137C is a variant of the Boeing c-137 and is one of the two VC-137Cs which were redesignated when downgraded from presidential use.

It has a maximum speed of 627 mph (1009 km/h), a cruise speed of 600 mph (966 km/h) and a range of 7,610 mi.
