Ilyushin Il-12 — Transport
Open in interactive gallery →See aircraft like this on the live radar →

The Ilyushin Il-12 (NATO reporting name Coach) was a Soviet twin-engine medium-haul piston airliner — the Soviet first dedicated postwar civil airliner. Sergey Ilyushin's design bureau developed the Il-12 in 1944-1946 as a Soviet alternative to the imported Lisunov Li-2 (licensed Douglas DC-3); the prototype first flew on 15 August 1945. About 663 Il-12s were built between 1947 and 1949 at GAZ-30 (Moscow Khodynka). The aircraft served Aeroflot and several export operators 1947-1968 before replacement by the turboprop Il-18.

The Il-12 used two Shvetsov ASh-82FN 14-cylinder twin-row radial engines (1,830 hp each). Maximum speed 407 km/h, range 1,500 km, service ceiling 7,000 m. Capacity: 27-32 passengers + 4 crew. The aircraft was designed to be operated from rough remote-area airfields in the Soviet Union — its rugged construction, simple systems, and tricycle landing gear (one of the first Soviet airliners with nose-wheel layout instead of tailwheel) made it Aeroflot's standard medium-haul aircraft for the late 1940s and early 1950s.

Il-12 service was concentrated in Aeroflot main-line Soviet domestic routes and East European exports. Czechoslovak Airlines, Polish LOT, and Chinese CAAC were the main export operators. The Soviet Air Forces operated several Il-12T military transport variants and Il-12D paratroop variants. The Il-12 was retired from front-line Aeroflot service in 1968 in favour of the larger Il-14 + Il-18; the last Soviet Air Forces Il-12s served as flying laboratories through the mid-1970s. About 4 Il-12 airframes survive in 2026 at Russian and Czech museums.

For Kids — a shorter, friendlier version

The Ilyushin Il-12 Coach was the first Soviet airliner built after WWII. The Il-12 first flew on August 15, 1945, just after WWII ended. About 663 Il-12s were built between 1947 and 1949. The Il-12 was Aeroflot's main medium-haul airliner of the late 1940s and early 1950s.

The Il-12 is 70 feet long with a 105-foot wingspan, longer than a Boeing 737. Two Shvetsov ASh-82FN radial engines each made 1,830 horsepower. Top speed is 253 mph, faster than most cars on a highway. The plane carried 27 to 32 passengers and 4 crew.

The Il-12 was tough, designed to operate from rough remote airfields across the huge Soviet Union. It had tricycle landing gear, one of the first Soviet airliners with a nose wheel instead of a tail wheel. This made the Il-12 easier to land and load than older Soviet planes.

Aeroflot used Il-12s on routes across the Soviet Union. The Il-12 also served Eastern European countries as a national airliner. By the late 1950s, the better Il-14 and turboprop Il-18 replaced the Il-12. Few Il-12s survive today.

Kids’ Questions

Why postwar?

During WWII (1941-1945), Soviet aircraft factories built fighters and bombers, not airliners. After WWII, the Soviet Union needed civilian planes to connect its huge country. The Il-12 was Ilyushin's first design for civilian use, fitting between the imported Lisunov Li-2 (a Soviet-built DC-3) and the bigger Il-18 turboprop. It served as the Soviet Union's main airliner for over 10 years.

Why tough construction?

The Soviet Union had thousands of small airfields in remote regions: Siberia, Kazakhstan, the Caucasus. Most were just flat patches of dirt or grass. The Il-12 needed to operate from these rough strips. Ilyushin built the plane sturdy, with simple systems and rugged landing gear. This made the Il-12 easy to maintain in places far from cities.

What replaced it?

The Ilyushin Il-14 (1953) was the direct improvement of the Il-12, with better engines, single-engine performance, and a refined cabin. About 1,348 Il-14s were built. Later, the turboprop Il-18 (1957) replaced both for longer routes. By the late 1960s, all Il-12s were retired.

Frequently Asked Questions

Why did the Soviets need the Il-12?

To replace the imported Lisunov Li-2 (Soviet-licensed Douglas DC-3) with a Soviet domestic design. The Li-2 had been Aeroflot's main airliner since the late 1930s; the Soviet Union wanted to use domestic-designed aircraft for civil aviation as a matter of industrial policy. The Il-12 was specifically designed as the Soviet successor to the DC-3 generation — slightly larger (27-32 passengers vs. 21), faster (407 km/h vs. 240 km/h), and with tricycle landing gear instead of tailwheel.

How is the Il-12 different from the Il-14?

The Il-12 was the first generation (1947-1949 production, 663 built). The Il-14 was the improved follow-on (1953-1959 production, ~1,348 built) with better engines, refined aerodynamics, and longer range. The Il-14 replaced the Il-12 in Aeroflot main-line service from 1954 onward; the Il-12 was retired by 1968.

How many Il-12s were built?

About 663 airframes between 1947 and 1949 at GAZ-30 (Moscow Khodynka). Production was relatively short; the Il-14 follow-on entered production in 1953.

Are any Il-12s preserved?

About 4 airframes survive at Russian aviation museums (Monino, Ulyanovsk Civil Aviation History Museum) and the Prague Aviation Museum. None are airworthy.
