Postwar Europe also served to play a major role in the development of the modern air cargo and air freight industry. A similar rear loading ramp even appeared in a somewhat different form on the nosewheel gear-equipped, late WW II era American Budd RB-1 Conestoga twin-engined cargo aircraft. These aircraft introduced the Trapoklappe, a powerful ramp/hydraulic lift with a personnel stairway centered between the vehicle trackway ramps, that raised the rear of the aircraft into the air and allowed easy loading. This aircraft, like most of its era, used tail-dragger landing gear which caused the aircraft to have a decided rearward tilt when landed. One important innovation for future cargo aircraft design was introduced in 1939, with the fifth and sixth prototypes of the Junkers Ju 90 four-engined military transport aircraft, with the earliest known example of a rear loading ramp. ![]() 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. The Ar 232 was intended to supplant the earlier Junkers Ju 52 freighter conversions, but only a few were built. The World War II German design, the Arado Ar 232 was the first purpose-built cargo aircraft. The Victorias also helped to pioneer air routes for Imperial Airways' Handley Page HP.42 airliners. Vickers Victorias played an important part in the Kabul Airlift of November 1928 – February 1929, when they evacuated diplomatic staff and their dependents together with members of the Afghan royal family endangered by a civil war. In February 1923 this was put to use by the RAF's Iraq Command who flew nearly 500 Sikh troops from Kingarban to Kirkuk in the first ever strategic airlift of troops. The Vickers Vernon, a development of the Vickers Vimy Commercial, entered service with the Royal Air Force as the first dedicated troop transport in 1921. In the UK during the early 1920s, the need was recognized for a freighter aircraft to transport troops and material quickly to pacify tribal revolts in the newly occupied territories of the Middle East. Although the earliest aircraft were not designed primarily as cargo carriers, by the mid-1920s aircraft manufacturers were designing and building dedicated cargo aircraft. Air Force Lockheed C-130 Hercules, the archetypal military transport aircraft, over the Atlantic Ocean in 2014 The Antonov An-225 Mriya, the heaviest cargo aircraftĪircraft were put to use carrying cargo in the form of air mail as early as 1911. History The Vickers Vernon, introduced in 1921, was the first cargo plane for military troops The Arado Ar 232, the first purpose built cargo aircraft A U.S. The Cargo Facts Consulting firm forecasts that the global freighter fleet will rise from 1,782 to 2,920 cargo aircraft from 2019 to 2039. ![]() Also in 2015, Boeing forecast belly freight to rise to 63% while specialised cargoes would represent 37% of a 1,200 billion ATKs in 2035. Freighters may be operated by civil passenger or cargo airlines, by private individuals or by the armed forces of individual countries.Īircraft designed for cargo flight usually have features that distinguish them from conventional passenger aircraft: a wide/tall fuselage cross-section, a high-wing to allow the cargo area to sit near the ground, numerous 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.īy 2015, dedicated freighters represent 43% of the 700 billion ATK (available tonne-kilometer) capacity, while 57% is carried in airliner's cargo holds. Such aircraft usually do not incorporate passenger amenities and generally feature one or more large doors for loading cargo.
