The Ilyushin Il-18 (Russian: Илью́шин Ил-18; NATO reporting name: Coot) is a large turboprop airliner that first flew in 1957 and became one of the best known and durable Soviet aircraft of its era. The Il-18 was one of the world's principal airliners for several decades and was widely exported. Due to the aircraft's airframe durability, many examples achieved over 45,000 flight hours and the type remains operational in both military and (to a lesser extent) civilian capacities. The Il-18's successor was the long range Il-62 jet airliner.

Variants[edit | edit source]

  • Il-18: Designation of the sole prototype of the Il-18 family.

    • Il-18RTL: Prototype for Il-20RT, converted from Il-18A c/n 188000401.
  • Il-18S: VIP variant of Il-18B.
  • Il-18SL: Designation of a number of different test and research aircraft, normally had a letter suffix like SL-18D for avionics trials.
  • Il-18T: This designation was given to civil and military cargo transport aircraft converted from Il-18A/B/V aircraft.
    • Il-18AT: Military transport/medevac version based on the Il-18A.
