The Sukhoi Su-80 (formerly known as the Sukhoi S-80) is a Russian twin-turboprop, twin-boom STOL transport aircraft.
The Su-80 program was supposed to start in the late 1990s, but due to lack of funds, it was postponed for several years. A prototype of the combined Freight/Passenger Su-80GP was built and its first flight was planned for early 1998, but the program was delayed again. The first flight of the prototype was at the 2001 MAKS in Moscow issued Zhukovsky.
On 4 September 2001, Igor Wotinzew started with the prototype, 82911, on his first flight. In early 2006, the Su-80 entered production in the KnAAPO factory in Komsomolsk-on-Amur.
The first model of the turboprop transporter Sukhoi S-80 was shown at the 46th Paris International Air and Space Show, 2005. [1] The plane is being developed by Sukhoi OKB and the aircraft factory in Komsomolsk/Amur under the "konversija" program. The aircraft is intended to replace the An-24/26, An-28 and Yak-40, and to compete with the Antonov An-38 . The design of the machine is very similar to the Scaled Composites ATTT and the Rockwell OV-10. It has three lift-generating surfaces: the primary wings; two fins at the rear of the fuselage which join the booms to the fuselage; and the horizontal stabilizer which joins the two vertical fins at the rear of the booms. Two General Electric CT7-9B turboprop engines are housed in bays at the front of the tail booms.
The sleek hull offers space for 30 passengers, and a "beaver-tail" cargo ramp is fitted at the rear of the fuselage, which allows for easy loading and unloading of cargo.
Eight aircraft from the second production (first definitive) batch were earmarked for delivery to customers. [2]
Blagoveshchensk Airlines, Chukotavia, Dalavia, the Petropavlovsk-Kamchatsky Air Enterprise, and Polar Airlines all signed preliminary agreements to acquire the type. [2] The KnAAPO factory airline was expected to be the Su-80's first operator. [2]
The Kazakhstan Border Guards tentatively ordered ten Su-80s, while the Chinese People's Liberation Army Air Force, Jordanian Air Force, Royal Malaysian Air Force, Indonesian Air Force and Republic of Korea Air Force all expressed interest. [2]
Ultimately, no aircraft performed active service. In 2022, it does not appear that any of these aircraft are operational.
There are two different models of the Su-80. The four pre-series aircraft were of a short-fuselage design, while the fifth, sixth and seventh prototypes were stretched by 1.4 m (4 ft 7 in) allowing an extra row of passenger seats. [2]

The Sukhoi Su-7 is a swept wing, supersonic fighter aircraft developed by the Soviet Union in 1955. Originally, it was designed as a tactical, low-level dogfighter, but was not successful in this role. On the other hand, the soon-introduced Su-7B series became the main Soviet fighter-bomber and ground-attack aircraft of the 1960s. The Su-7 was rugged in its simplicity, but its Lyulka AL-7 engine had such high fuel consumption that it seriously limited the aircraft's payload, as even short-range missions required that at least two hardpoints be used to carry drop tanks rather than ordnance.
The Sukhoi Su-33 is a Soviet/Russian all-weather carrier-based twin-engine air superiority fighter designed by Sukhoi and manufactured by Komsomolsk-on-Amur Aircraft Production Association, derived from the Su-27 and initially known as the Su-27K. Compared with the Su-27, the Su-33 has a strengthened undercarriage and structure, folding wings and stabilators, all for carrier operations. The Su-33 has canards, and its wings are larger than the Su-27 for a slower stall speed. The Su-33 has upgraded engines and a twin nose wheel, and is air refuelable.
The Aermacchi AM.3 was the result of a joint venture between Aermacchi and Aeritalia in response to an Italian Army requirement for an aircraft to replace the Cessna L-19, and was initially designated the MB-335.
The Valmet L-90 Redigo is a turboprop-powered military basic trainer aircraft and liaison aircraft, a development of Valmet's earlier training aircraft for the Finnish Air Force. The L-90 was the last military aircraft designed and produced in Finland.
The Valmet L-70 Vinka is a Finnish-designed piston-powered military basic trainer aircraft of the 1970s. A production run of 30 aircraft were built for the Finnish Air Force in the early 1980s, and although the type was not exported, it formed the basis of the turboprop-powered Aermacchi M-290 RediGO.
The Douglas A2D Skyshark was an American turboprop-powered attack aircraft built by the Douglas Aircraft Company for the United States Navy. The program was substantially delayed by engine reliability problems, and was canceled because more promising jet attack aircraft had entered development and the smaller escort carriers the A2D was intended to utilize were being phased out.

The Antonov An-14 Pchelka or Pchyolka, Bdzhilka is a Soviet utility aircraft which was first flown on 15 March 1958. It was a twin-engined light STOL utility transport, with two 300 hp Ivchenko AI-14RF radial piston engines. Serial production started in 1966, and about 300 examples were built by the time production ended in 1972. The An-14 failed to replace the more successful An-2 biplane, which was manufactured until 1990,. The An-14's successor, the An-28 with turboprop engines, is still manufactured at PZL Mielec factories in Poland, under the names PZL M28 Skytruck and PZL M28B Bryza.
The Embraer EMB 121 Xingu is a twin-turboprop fixed-wing aircraft built by the Brazilian aircraft manufacturer, Embraer. The design is based on the EMB 110 Bandeirante, using its wing and engine design merged with an all-new fuselage. The EMB 121 first flew on 10 October 1976.
The Piper PA-48 Enforcer is an American turboprop-powered light close air support aircraft built by Piper in the 1970s. It is a development of the World War II-era North American P-51 Mustang fighter. The Enforcer concept was originally created and flown as the Cavalier Mustang by David Lindsay, owner of Cavalier Aircraft, in response to the United States Air Force PAVE COIN program, but Cavalier did not have the manufacturing abilities to mass-produce the Enforcer, so the program was sold to Piper by Lindsay in 1970.

The Vulcanair SF.600 Canguro was a feederliner developed in Italy in the late 1970s. Despite a number of attempts to put the aircraft into series production, only a small number were ever built. The Canguro was a high-wing cantilever monoplane of conventional configuration with a fuselage of rectangular cross-section and a high-set tail. The tricycle undercarriage was not retractable, and its main units were carried on sponsons on the fuselage sides. SIAI Marchetti provided funding towards the construction of the prototype, and constructed this aircraft at the former Aviamilano plant. After flight testing proved positive, the type was put on sale, but failed to attract buyers in any number, even when the original piston engines were exchanged for turboprops and retractable undercarriage was offered as an option.
