The Lockheed C-5 Galaxy is the undisputed heavyweight champion of American military airlift, a colossal strategic transport aircraft designed to carry any piece of equipment in the U.S. Army's inventory to any point on the globe. With its cavernous cargo hold and distinctive "kneeling" landing gear, the Galaxy can swallow two M1 Abrams tanks or six Apache helicopters with ease. Its large nose and rear doors allow for "drive-through" loading and unloading, drastically reducing turnaround times. From its introduction in the late 1960s to the modernized C-5M Super Galaxy with its powerful and efficient GE F138 engines, this "Aluminum Overcast" has been the backbone of every major U.S. military deployment and countless humanitarian relief efforts.
