Ilyushin Il-76 Candid

The Ilyushin Il-76 (NATO reporting name: Candid) is a multi-purpose four-engined strategic airlifter designed by the Ilyushin design bureau. It was first planned as a commercial freighter in 1967. Intended as a replacement for the Antonov An-12, the Il-76 was designed for delivering heavy machinery to remote, poorly-serviced areas of the USSR. Military versions of the Il-76 have seen widespread use in Europe, Asia and Africa, including use as an airborne refueling tanker or as a command center.

The Il-76 has seen extensive service as a commercial freighter for ramp-delivered cargo, especially for outsized or heavy items unable to be otherwise carried. It has been used as emergency response transport for civilian evacuations and to deliver humanitarian/disaster relief aid around the world, especially to undeveloped areas due to its ability to operate from unpaved runways. Specialist models have also been produced for aerial fire-fighting and zero-G training.

First aircraft were delivered to the Soviet Air Force in June 1974 and it became the main Soviet strategic transport aircraft. From 1976 it was operated by the Aeroflot lines.

Between 1979 and 1991, the Soviet Air Force Il-76s made 14,700 flights into Afghanistan, transporting 786,200 servicemen, and 315,800 tons of freight. The Il-76 carried 89% of Soviet troops and 74% of the freight that was airlifted.  As Afghan rebels were unable to shoot down high-flying Il-76s, their tactics were to try and damage it at take-off or landing. Il-76s were often hit by shoulder-launched Stinger and Strela heat-seeking missiles and large-calibre machine-gun fire, but because the strong airframes were able to take substantial damage and still remain operational, the aircraft had a remarkably low attrition rate during the period of conflict. Building on that experience, the bulk of the Canadian Forces equipment into Afghanistan is flown in using civilian Il-76.  In 2006, the Russian Air Force had about 200 Il-76s. Civilian users in Russia have 108.

The Il-76 is also in use as an airborne tanker, otherwise known as a refueller (Il-78, some 50 were made), and a waterbomber. Its airframe was used as a base for the Beriev A-50 'Mainstay' AWACS aircraft (some 25 were made). Still more applications have been found in Antarctic support flights and simulated weightlessness training for cosmonauts.  Beriev and NPO Almaz also developed an airborne laser flying laboratory designated A-60, of which two were built, although little is known about it as the project is still classified.
