"The Lockheed C-5M Super Galaxy is the world's largest military transport aircraft, capable of carrying massive and oversized cargo over long distances for the U.S. Air Force. (AI Overview)

"Its massive size allows it to transport items like two M1 Abrams tanks or a Chinook helicopter, and it features unique capabilities such as simultaneous front and rear loading for faster turnaround."

Key features of the C-5M Super Galaxy

• Cargo capacity: It can hold over 35,000 cubic feet of cargo, which is five times the volume of a C-141 Starlifter. It can carry payloads such as two M1 Abrams tanks or seven UH-1 Huey helicopters. 
• Loading and unloading: The C-5M has both a nose and rear door that open with full-width drive-on ramps. This allows ground crews to load and off-load cargo simultaneously from both ends, significantly reducing transfer times. 
• Engine and performance: It is powered by four General Electric CF6-80C2 engines, which provide the power needed to carry heavy loads over intercontinental ranges. It has a maximum takeoff weight exceeding 800,000 pounds. 
• Versatility: The C-5M can take off and land on relatively short runways, and its landing gear can be individually raised for maintenance or replaced, making it a highly versatile aircraft.
• Modernization: The C-5M is a modernized version of the original C-5 Galaxy, featuring a new maintenance diagnostics system and more powerful, efficient engines. 
  

"The Lockheed C-5 Galaxy is a large military transport aircraft designed and built by Lockheed, and now maintained and upgraded by its successor, Lockheed Martin. It provides the United States Air Force (USAF) with a heavy intercontinental-range strategic airlift capability, one that can carry outsized and oversized loads, including all air-certifiable cargo.

"The Galaxy has many similarities to the smaller Lockheed C-141 Starlifter and the later Boeing C-17 Globemaster III. The C-5 is among the largest military aircraft in the world. All 52 in-service aircraft have been upgraded to the C-5M Super Galaxy with new engines and modernized avionics designed to extend its service life to 2040 and beyond." (Wikipedia)

"The C-5 Galaxy's development was complicated, including significant cost overruns, and Lockheed suffered significant financial difficulties. Shortly after entering service, cracks in the wings of many aircraft were discovered and the C-5 fleet was initially restricted in capability until corrective work was completed.

"The USAF has operated the C-5 since 1969. In that time, the airlifter supported US military operations in all major conflicts including Vietnam, Iraq, Yugoslavia, and Afghanistan, as well as allied support, such as Israel during the Yom Kippur War and operations in the Gulf War. The Galaxy has also distributed humanitarian aid, provided disaster relief, and supported the US space program."  (Wikipedia)

"The C-5M Super Galaxy is equipped with five sets of landing gear, 28 wheels, four General Electric CF6-80C2-L1F (F-138) commercial engines, and a state-of-the-art maintenance diagnostics system. It can carry oversized cargo over intercontinental ranges and can take off and land on relatively short runways," the U.S. Air Force says.

"Both the nose and aft doors open, allowing ground crews to simultaneously load and off-load cargo from both ends, reducing cargo transfer times. The full-width drive-on ramps at each end enable double rows of vehicles to be transported. The maintenance diagnostics system has the ability to record and analyze data from more than 7,000 test points, reducing maintenance and repair time.

"The C-5M, with a cargo load of 281,001 pounds (127,460 kilograms), can fly 2,150 nautical miles, offload, and fly to a second base 500 nautical miles away from the original destination — all without aerial refueling. With aerial refueling, the aircraft's range is limited only by crew endurance."

"C-5 modernization provides greatly improved reliability, efficiency, maintainability and availability, while ensuring this critical national strategic airlift resource continues serving the warfighter well into the 21st century," Lockheed martin says.

Since its inception, the C-5 has been a critical instrument of national policy. From the defense of Israel in the Yom Kippur war, to the air bridge supporting coalition forces in Desert Storm, the C-5 delivers unmatched capability to carry enormous loads over global distances. 

"The C-5 modernization approach is proven. In three flights operating out of Dover AFB, Delaware, a joint U.S. Air Force and Lockheed Martin crew set 43 world aviation records, demonstrating the C-5M’s ability to redefine global airlift. In deployed airlift operations, the C-5M is demonstrating a new era of highly capable, reliable and affordable airlift."

"The Lockheed C-5M Super Galaxy is a large, modernized strategic transport aircraft used by the U.S. Air Force to move oversized cargo and personnel globally. It is the largest aircraft in the U.S. Air Force's inventory, featuring new engines, a modernized avionics system, and a unique two-level cargo compartment that allows simultaneous loading and unloading through both the front and rear doors. (AI Overview)

"The C-5M's cargo capacity can include multiple large vehicles, like up to six AH-64 Apache helicopters, and its mission is to provide critical logistics support for military operations."
