With the change of Administration last month, the National Geographic Channel ran a special on Air Force One, calling it America’s Airborne Command Post.
Unfortunately – that statement was just PR. As the documentary showed (in a recap of the flight during 9/11), Air Force One is not a ‘command post’ per se. It is a VIP transport, with a very secure communications system.

The ‘real’ Airborne Command Post is currently a set of four Boeing 747-200 aircraft that were modified/enhanced, and are currently designated by the US Air Force as E-4B’s.
The history of this program;
- ordered – Feb 1973
- first delivered – Dec 1974
- fleet upgraded to E-4B standard – 1985
- Expected to continue in service to 2015
The E-4B modification consisted of EMP hardening of the aircraft electronics and systems, and replacing the original engine’s.
The four airplanes are based at Offut AFB in Nebraska, and will rotate through Andrews AFB (outside of Washington DC) and Wright Patterson AFB (Dayton, OH). Since the US no longer keeps the bomber force on alert – the E-4’s are one of the few aircraft that are maintained on a 24-hour alert status.
During the attacks on 9/11 – people had reported seeing a large, 4 engine plane overflying Washington, DC and this turned out to be an E-4B, even though the DOD never admitted it was theirs. According to later reports – there was an E-4B at Andrews AFB, participating in Exercise “Global Guardian” that was cancelled when the first plane hit the World Trade Center (and the E-4B was sent airborne).
