Which one among the following statements is correct with regard to the C-5M Super Galaxy ?

The C-5M Super Galaxy is a large military transport aircraft operated by the United States Air Force. It is an upgraded version of the Lockheed C-5 Galaxy, designed for strategic inter-theater transportation of heavy cargo, personnel, and outsized equipment over intercontinental ranges. As the largest aircraft in the U.S. Air Force inventory, it serves as a heavy-lift airlifter capable of carrying unusually large loads, such as helicopters and tanks, and can even perform simultaneous drive-through loading and unloading via its front and rear cargo doors. The C-5M modernization program involved converting existing C-5 airframes with new engines and avionics to improve reliability and fuel efficiency, a process that was completed for the fleet in August 2018. It is not a helicopter, a celestial body, or a fighter aircraft.
