 that became one of the best known Soviet aircraft of its era as well as one of the most popular and durable, having first flown in 1957 and still in use over 50 years later. 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 achieved over 45,000 flight hours. The Il-18's successor was the long range Il-62 jet airliner.

 aircraft shared the designation Ilyushin Il-18. The first Il-18 was a propeller-driven airliner of 1946 but after a year of test flights that programme was abandoned.

In the early 1950s a need to replace older designs and increase the size of the Soviet civil transport fleet, a Soviet Council of Ministers directive was issued on 30 December 1955 to the chief designers Kuznetsov and Ivenchko to develop new turboprop engines and to Ilyushin and Antonov to design an aircraft to use these engines. The two aircraft designs were developed as the Ilyushin Il-18 and the Antonov An-10

.

The Il-18 design had started in 1954 before the directive was issued and experience with the piston-engined Il-18 was used although the aircraft was a new design. The design was for a four-engined low-wing monoplane with a circular pressurised fuselage and a conventional tail. The forward retracting tricycle landing gear had four-wheels fitted on the main leg bogies, the main legs bogies rotated 90 degrees and retracted into the rear of the inboard engines. A new feature at the time was the fitting of a weather radar in the nose and it was the first soviet airliner to have an automatic approach system. The aircraft has two entry doors on the port-side before and after the wing and two overwing emergency exist on each side.

The prototype SSSR-L5811 was rolled out in June 1957 and after ground-testing it began taxying test and high-speed runs on 1 July 1957. On 4 July 1957 the prototype first flew from Khodynka. On 10 July 1957 the aircraft was flown to Moscow-Vnukovo Airport

. The Il-18 type was formally named Moskva and this was painted on the fuselage, although the name was not used when the aircraft entered production.

The Moscow Machinery Plant No. 30 located at Khodynka near where the Ilyushin design office and the prototype had been built was chosen to manufacture the aircraft. During 1957 the plant began to reduce its production of the Ilyushin Il-14

 and prepare to build the production aircraft designated IL-18A. The Il-18A was only different to the prototype in minor details mainly internal configuration to increase the seating from 75 to 89.

The first production aircraft were powered by the Kuznetsov NK-4 but the engines were plagued with problems so the Council of Ministers decreed in July 1958 that all production from November 1958 would use the Ivchenko AI-20

 and earlier production would be re-engined. Only 20 IL-18As were built before production changed to the improved Il-18B, this new variant had a higher-gross weight, the nose was re-designed with a larger radome which increased the length by 20 cm. The first Il-18B flew on 30 September 1958 powered by the AI-20, a VIP variant was also built as the IL-18S for the Soviet Air Force.

With experience of the earlier aircraft a further improvement was the Il-18V variant. The Il-18V was structural the same but the interior was re-designed including moving the galley and some minor system changes. The first Il-18V appeared in December 1959 and was to continue into production until 1965 after 334 had been built.
