The Doomsday plane is an unofficial denomination of a class of aircraft which is used as an Airborne Command Post in an event of nuclear war, disaster or other large scale conflicts that threaten key military and government infrastructure.

The only countries that have designed and manufactured such aircraft are the United States and the Russian Federation.

The Doomsday Plane set off from MacDill Air Force Base earlier on Wednesday.
