The Ilyushin Il-18 is a large turboprop airliner that first flew in 1957 and became one of the best known Soviet aircraft of its era. The Il-18 was one of the Soviet Union's principal airliners for several decades and was widely exported. Due to the aircraft's durability, many examples achieved over 45,000 flight hours and the type remains operational in both military and to a lesser extent in civilian capacities. The Il-18's successor was the longer-range Ilyushin Il-62.
