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.
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.
As the Air Force’s largest and only strategic airlifter, the C-5 Galaxy can carry more cargo farther distances than any other aircraft. With a payload of six Mine Resistant Ambush Protected vehicles (MRAPs) or up to five helicopters, the C-5 can haul twice as much cargo as any other airlifter.
One of the largest aircraft in the world, the C-5 Galaxy is the primary lift aircraft in the U.S. military for moving outsized cargo to global theaters of operation.
