Ilyushin Il-18 (1946)
The Ilyushin Il-18 (NATO reporting name: Clam) was a Soviet four-engined airliner designed and built by Ilyushin immediately after World War II. Although the aircraft itself was successful, its Shvetsov ASh-73TK engines were too unreliable for civilian use and were further needed to equip the Tupolev Tu-4 bomber, so it was cancelled in 1948. == Development == The Il-18 was developed to meet Aeroflot's need for a high-altitude, long-range aircraft to fly its long-haul national and international routes.
