Cargo aircraft
Encyclopedia
A cargo aircraft (also known as freight aircraft, freighter, airlifter, or cargo jet) is a fixed-wing aircraft
designed or converted for the carriage of goods, rather than passengers. They are usually devoid of passenger amenities, and generally feature one or more large doors for the loading and unloading of cargo. Freighters may be operated by civil passenger or cargo airline
s, by private individuals or by the armed forces
of individual countries. However most air freight is carried in special ULD containers
in the cargo
holds of passenger aircraft.
Aircraft designed for cargo flight use have a number of features that distinguish them from conventional passenger aircraft: a "fat" looking fuselage, a high-wing to allow the cargo area to sit near the ground, a large number of wheels to allow it to land at unprepared locations, and a high-mounted tail to allow cargo to be driven directly into and off the aircraft.
The earliest "true" cargo aircraft is arguably the World War II
German design, the Arado Ar 232
. The Ar 232 was intended to supplant the earlier Junkers Ju 52
freighter conversions, but only small numbers were built. Most other forces used freighter versions of airliners in the cargo role as well, most notably the C-47 Skytrain
version of the Douglas DC-3
, which served with practically every allied nation. Post war Europe
also served to play a major role in the development of the modern air cargo and air freight industry during what became known as the "Cold War

residents with food and supplies, in a virtual around the clock air bridge; after the Soviet Union

In the years following the war era a number of new custom-built cargo aircraft were introduced, often including some "experimental" features. For instance, the US's C-82 Packet
featured a removable cargo area, while the C-123 Provider
introduced the now-common upswept tail with a drop-down loading and unloading ramp. But it was the introduction of the turboprop

Fixed-wing aircraft
A fixed-wing aircraft is an aircraft capable of flight using wings that generate lift due to the vehicle's forward airspeed. Fixed-wing aircraft are distinct from rotary-wing aircraft in which wings rotate about a fixed mast and ornithopters in which lift is generated by flapping wings.A powered...

History
Aircraft were put to use carrying cargo in the form of air mail as early as 1911. Although the earliest aircraft were not designed primarily as cargo carriers, by the mid 1920s aircraft manufacturers were designing and building dedicated cargo aircraft.The earliest "true" cargo aircraft is arguably the World War II
