The Lisunov Li-2 (NATO reporting name: Cab), originally designated PS-84, was a license-built Soviet-version of the Douglas DC-3. It was produced by Factory #84 in Moscow-Khimki and, after evacuation in 1941, at TAPO in Tashkent. The project was directed by aeronautical engineer Boris Pavlovich Lisunov.
The Soviet Union received its first DC-2 in 1935. A total of 18 DC-3s had been ordered on 11 April 1936, and the government of the USSR purchased 21 DC-3s for operation by Aeroflot before World War II. A production licence was awarded to the government of the USSR on 15 July 1936. Lisunov spent two years at the Douglas Aircraft Company, between November 1936 and April 1939 translating the design. One of the engineers who accompanied him to Douglas was Vladimir Mikhailovich Myasishchev. Design work and production were undertaken at State Aviation Factory 84 in Khimki (now a suburb of Moscow).[5] The Soviet version was given the designation PS-84 – Passazhirskiy Samolyot 84, passenger airplane 84 (i.e. made in GAZ/State Aircraft Plant No. 84).
Despite the original intention to incorporate as few changes as necessary to the basic design,[6] the GAZ-84 works had to make some 1,293 engineering change orders to the original Douglas drawings, involving part design, dimensions, materials and processes, most as a part of metrication of the design from U.S. customary units to suit Soviet standards,[7] no small task for Vladimir Myasishchev to accomplish. The well-established Shvetsov OKB-19 design bureau, responsible for the great bulk of the Soviets' air-cooled radial aviation powerplant designs of the 1930-40s, used their Shvetsov ASh-62IR radial engines, a Soviet development of the nine-cylinder Wright R-1820Cyclone 9, to power the PS-84. The same Wright AeronauticalCyclone 9 radial also powered the earliest Douglas DST "Sleeper Transport" versions, and initial 21-passenger versions, of the original American DC-3 airliner.
The Soviet standard design practice usually mandated fully shuttered engines in order to cope with temperature extremes. A slightly shorter span was incorporated, but many of the other alterations were less evident. The passenger door was moved to the right or starboard side of the fuselage, with a top-opening cargo door on the left or port side in place of the original passenger door. The structural reinforcement included slightly heavier skins, because the metric skin gauges were not exact equivalents of the American alloy sheet metal. Standard Soviet metric hardware was different and the various steel substructures such as engine mounts and landing gear, wheels, and tires were also quite different from the original design. Later modifications allowed the provision of ski landing gear in order to operate in remote and Arctic regions. The first PS-84s had begun to emerge from the GAZ-84 production line by 1939.[8]
By the time Germany invaded the USSR on 22 June 1941, 237 PS-84s had been built at GAZ-84, all in civil passenger configuration. In response to the invasion, the Kremlin set in motion a plan to relocate much of the industrial capability of the Soviet Union to the East, with production of the Li-2 ending up at GAZ-33 in Tashkent, now the capital of Uzbekistan. After a monumental struggle, the factory was producing PS-84s again by January 1942.[9][10]
GAZ-124 at Kazan also built ten aircraft before the start of World War II, and 353 Li-2Ts were built by GAZ-126 at Komsomolsk-on-Amur between 1946 and 1950, before that plant switched to MiG-15 production.[11]
Some military versions of the Li-2 also had bombing equipment—such as bomb sight and bomb racks, and defensive turret, not unlike the military C-47 development of the DC-3. The defensive armaments consisted of MV-3 dorsal turret with a 7.62mm (.30in) ShKAS machine gun, later replaced with a 12.7mm (.50in) UBT heavy machine gun. Additionally two ShKAS machine guns on pivot mount could also be mounted on both sides of the rear fuselage near the cargo door. A version designated Li-2VV (Voyenny Variant = military variant) had a redesigned nose for extra ShKAS machine gun and could carry up to four 250kg (551lb) bombs under the central fuselage. Smaller bombs could be carried inside the fuselage and thrown out of the cargo door by the crew.[12]
Operational history
Lisunov Li-2 of Aeroflot at Monino near Moscow in 1994
The PS-84 had flown with Aeroflot primarily as a passenger transport before World War II. When Germany attacked the Soviet Union in 1941 many of the PS-84s were taken into military use and redesignated the Lisunov Li-2 in 1942. The military models were equipped with a machine gun on dorsal turret. The aircraft were used for transport, partisan supply, bombing, and as ambulance aircraft.[12]
A total of 4,937[3] aircraft were produced of all Li-2 variants between 1940 and 1954 and it saw extensive use in Eastern Europe until the 1960s. The last survivors in use were noted in China and Vietnam during the 1980s.[3] There were many versions, including airliner, cargo, military transport, reconnaissance, aerial photography, parachute drop, bomber and high altitude variants. In Poland they were fitted for cropdusting against forest pests.[13] The Li-2 also saw extensive service in the Chinese Air Force in the 1940s and 1950s.
Only one Li-2 restored to airworthy condition exists in Europe. The Hungarian registered HA-LIX was built in 1949 in Airframe Factory Nr.84 (GAZ-84) of Tashkent, as serial number 18433209 and was operated by MALÉV till 1964. It was withdrawn to a museum in 1974 as an airforce parachute trainer airplane. After a complete reconstruction finished in 2001 it flies sightseeing tours and regularly participates at air shows. It is operated by the Goldtimer Foundation, based at Budaörs Airport, Budapest, Hungary.[15] The North Korean Air Force is known to still use a number of Li-2s for transport, although they may have been decommissioned despite their continued presence on certain airbases.
Original passenger airliner, equipped with 14-28 seats. Somewhat smaller span and higher empty weight, it was also equipped with lower-powered engines compared to the DC-3. The cargo door was also transposed to the right side of the fuselage.

PJSC Aeroflot – Russian Airlines, commonly known as Aeroflot, is the flag carrier and the largest airline of Russia. Aeroflot is headquartered in the Central Administrative Okrug, Moscow, with its hub being Sheremetyevo International Airport. The Federal Agency for State Property Management, an agency of the Government of Russia, owns 73.77% of the company, with the rest of the shares being public float.
The Douglas DC-3 is a propeller-driven airliner manufactured by Douglas Aircraft Company, which had a lasting effect on the airline industry in the 1930s to 1940s and World War II. It was developed as a larger, improved 14-bed sleeper version of the Douglas DC-2. It is a low-wing metal monoplane with conventional landing gear, powered by two radial piston engines of 1,000–1,200 hp (750–890 kW). Although the DC-3s originally built for civil service had the Wright R-1820 Cyclone, later civilian DC-3s used the Pratt & Whitney R-1830 Twin Wasp engine. The DC-3 has a cruising speed of 207 mph (333 km/h), a capacity of 21 to 32 passengers or 6,000 lbs (2,700 kg) of cargo, and a range of 1,500 mi (2,400 km), and can operate from short runways.
The Yakovlev Yak-40 is a regional jet designed by Yakovlev. The trijet's maiden flight was in 1966, and it was in production from 1967 to 1981. Introduced in September 1968, the Yak-40 has been exported since 1970.
The Douglas C-47 Skytrain or Dakota is a military transport aircraft developed from the civilian Douglas DC-3 airliner. It was used extensively by the Allies during World War II. During the war the C-47 was used for troop transport, cargo, paratrooper, for towing gliders and military cargo parachute drops. The C-47 remained in front-line service with various military operators for many years. It was produced in approximately triple the numbers as the larger, much heavier payload Curtiss C-46 Commando, which filled a similar role for the U.S. military.
This is a list of aviation-related events from 1956.
The Tupolev ANT-7, known by the VVS as the Tupolev R-6, was a reconnaissance aircraft and escort fighter of the Soviet Union. The R-6 traces its roots back to early 1928 when the Soviet Air Force needed a long-range multirole aircraft. The requirements were that it could be used for long-range transport, defensive patrolling, reconnaissance, light bombing and torpedo attack.
The Ilyushin Il-14 was a Soviet twin-engine commercial and military personnel and cargo transport aircraft that first flew in 1950, and entered service in 1954. The Il-14 was also manufactured in East Germany by VEB Flugzeugwerke as the VEB 14 and in Czechoslovakia as the Avia 14. The Ilyushin Il-14 was typically replaced by the Antonov An-24 and Yakovlev Yak-40.
The Yakovlev Yak-16 was a Soviet light transport that first flew in 1947. Prototypes were built in both passenger and military cargo versions, but neither was put into production as the Antonov An-2 was felt to be more versatile.
The Polikarpov R-5 was a Soviet reconnaissance bomber aircraft of the 1930s. It was the standard light bomber and reconnaissance aircraft of the Soviet Air Force for much of the 1930s, while also being used heavily as a civilian light transport, some 7,000 being built in total.
On 7 March 1965, an Aeroflot Li-2 operating as Aeroflot Flight 542 crashed shortly after takeoff from Abakan. Approximately 40 minutes after departure, the aircraft banked left and dived into the mountains of the Krasnoyarsk Krai region of the USSR. All 31 passengers and crew died, making it the deadliest known accident involving the Li-2.
