U.S. Air Force Largest Aircraft Showcases Its Insane Capability

Welcome back to US Military News for a new documentary video about the C-5 Galaxy, the US Air Force biggest cargo aircraft.

After some touch-ups, the Air Force's biggest plane is ready to soar for decades, but the service has other transport problems to solve

The upgrade program involved 70 modifications to improve the plane's reliability, efficiency, maintainability, and availability. Among them were changes to the airframe; to its environmental, pneumatic, and hydraulic systems; and to the landing gear and flight controls.

The main addition was more powerful engines — an upgrade from four General Electric TF-39 engines to GE F-138 engines, which are quieter and will allow the Super Galaxy to haul more cargo with less room needed for takeoff.
