Air Force Tests New $13B Airborne Command Aircraft

The U.S. Air Force is testing a new, super-secure plane called the E-4C SAOC, also known as the 'Doomsday Plane'.

This plane, costing $13 billion, is designed to be a flying command center, so the President can still give orders even if ground bases are destroyed.

It's made from a Boeing 747-8, and will have special shields and computers to protect against things like radiation and hacking.

The planes will replace older ones that have been used for a long time.

The tests will check how well the plane can fly, communicate, and handle emergencies.

Sierra Nevada Corporation (SNC) is building the planes and has expanded their facilities to handle the work.
