Beskrivelse

A great video of the worlds largest military aircraft the US Military C-5 Galaxy. The Lockheed C-5 Galaxy is a large military transport aircraft originally 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 outsize and oversize loads, including all air-certifiable cargo. The Galaxy has many similarities to its smaller Lockheed C-141 Starlifter predecessor, and the later Boeing C-17 Globemaster III. The C-5 is among the largest military aircraft in the world.

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 restricted in capability until corrective work was completed. The C-5M Super Galaxy is an upgraded version with new engines and modernized avionics designed to extend its service life beyond 2040.

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 been used to distribute humanitarian aid and disaster relief, and supported the US Space Shuttle program.

Design[edit]
Overview[edit]
The C-5 is a large high-wing cargo aircraft with a distinctive high T-tail fin (vertical) stabilizer, and with four TF39 turbofan engines mounted on pylons beneath wings that are swept 25 degrees. Similar in layout to its smaller predecessor, the C-141 Starlifter, the C-5 has 12 internal wing tanks and is equipped for aerial refueling. Above the plane-length cargo deck, it provides an upper deck for flight operations and for seating 75 passengers including the embarked loadmaster crew, all who face to the rear of the aircraft during flight. Full-open(able) bay doors at both nose and tail enable "drive-through" loading and unloading of cargo.[49]

The cargo hold of the C-5 is one foot longer than the entire length of the first powered flight by the Wright Brothers at Kitty Hawk.[50] For its voracious consumption of fuel and its maintenance and reliability issues[51] the Galaxy's aircrews have nicknamed it FRED, for: Fucking[N 1] Ridiculous, Economic/Environmental Disaster.[51]


Heavy equipment stowed inside a C-5. Aircrew loadmasters ensure cargo is secured and balanced before takeoff.
Takeoff and landing distance requirements for the plane at maximum-load gross weight are 8,300 ft (2,500 m) and 4,900 ft (1,500 m), respectively. Its high flotation main landing gear provides 28 wheels to distribute gross weight on paved or earth surfaces. The rear main landing gear can be made to caster to make a smaller turning radius, and rotates 90 degrees after takeoff before being retracted. "Kneeling" landing gear permits lowering the aircraft when parked, thereby presenting the cargo deck at truck-bed height to facilitate loading and unloading operations.[54]

The C-5 features a Malfunction Detection Analysis and Recording (MADAR) system to identify errors throughout the aircraft.[33]

The cargo compartment is 121 ft (37 m) long, 13.5 ft (4.1 m) high, and 19 ft (5.8 m) wide, or just over 31,000 cu ft (880 m3). It can accommodate up to 36 463L master pallets or a mix of palletized cargo and vehicles. The nose and aft cargo-bay doors open the full width and height of the cargo bay to maximize efficient loading of oversized equipment. Full width ramps enable loading double rows of vehicles from either end of the cargo hold.[49]

The Galaxy C-5 is capable of moving nearly every type of military combat equipment, including such bulky items as the Army armored vehicle launched bridge (AVLB), at 74 short tons (67 t), from the United States to any location on the globe;[49] and of accommodating up to six Boeing AH-64 Apache helicopters or five Bradley Fighting Vehicles at one time.[32]

Operational history[edit]

Personnel unload cargo from a C-5 Galaxy at Pegasus Field, an ice runway near McMurdo Station, Antarctica in 1989.
The first C-5A was delivered to the USAF on 17 December 1969. Wings were built up in the early 1970s at Altus AFB, Oklahoma; Charleston AFB, South Carolina; Dover AFB, Delaware; and Travis AFB, California. The C-5's first mission was on 9 July 1970, in Southeast Asia during the Vietnam War.[55] C-5s were used to transport equipment and troops, including Army tanks and even some small aircraft, throughout the later years of the US action in Vietnam.[56] In the final weeks of the war, prior to the Fall of Saigon, several C-5s were involved in evacuation efforts. During one such mission a C-5A crashed while transporting a large number of orphans, with over 140
