The C-5M Super Galaxy is a strategic transport aircraft and is the largest aircraft in the Air Force inventory. Its primary mission is to transport cargo and personnel for the Department of Defense. The Super Galaxy is America’s premier global direct delivery weapon system and the only strategic airlifter capable of linking the homeland directly to the warfighter in all theaters of combat without refueling.

The C-5M’s demonstrated improvements in performance and efficiency validate the value to the taxpayer of modernizing proven and viable aircraft. The C-5M can carry twice the cargo of other strategic airlift systems and is the only strategic airlifter capable of carrying 100 percent of certified air-transportable cargo. The C-5M is a modernized version of the legacy C-5 designed and manufactured by Lockheed Martin.
