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.
The C-5 Galaxy has been operated by USAF since 1969. In that time, it has been used to support US military operations in all major conflicts. The C-5 has also been used to distribute humanitarian aid and disaster relief, and supported the US Space Shuttle program run by NASA.
