The Tupolev ANT-20 Maxim Gorky was a Soviet eight-engine aircraft, the largest in the world during the 1930s. Its wingspan was similar to that of a modern Boeing 747, and was not exceeded until the 64.6-metre (212 ft) wingspan Douglas XB-19 heavy bomber prototype first flew in 1941.
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 Petlyakov Pe-8 was a Soviet heavy bomber designed before World War II, and the only four-engine bomber the USSR built during the war. Produced in limited numbers, it was used to bomb Berlin in August 1941. It was also used for so-called "morale raids" designed to raise the spirit of the Soviet people by exposing Axis vulnerabilities. Its primary mission, however, was to attack German airfields, rail yards and other rear-area facilities at night, although one was used to fly the People's Commissar of Foreign Affairs Vyacheslav Molotov from Moscow to the United States in 1942.
The Tupolev TB-1 was a Soviet bomber aircraft, an angular monoplane that served as the backbone of the Soviet bomber force for many years, and was the first large all-metal aircraft built in the Soviet Union.
The Tupolev TB-3 was a monoplane heavy bomber deployed by the Soviet Air Force in the 1930s and used during the early years of World War II. It was the world's first cantilever wing four-engine heavy bomber. Despite obsolescence and being officially withdrawn from service in 1939, the TB-3 performed bomber and transport duties throughout much of World War II. The TB-3 also saw combat as a Zveno project fighter mothership and as a light tank transport.
The Tupolev Tu-2 was a twin-engined Soviet high-speed daylight and frontline bomber aircraft used during World War II. The Tu-2 was tailored to meet a requirement for a high-speed bomber or dive-bomber, with a large internal bomb load and speed similar to that of a single-seat fighter. Designed to challenge the German Junkers Ju 88, the Tu-2 proved comparable and was produced in torpedo, interceptor and reconnaissance versions. The Tu-2 was an effective combat aircraft and it played a key role in the final offensives of the Red Army.
The Breguet 19 was a sesquiplane bomber and reconnaissance aircraft which was also used for long-distance flights and was designed by the French Breguet company and produced from 1924.
The Lublin R-VIII was a Polish bomber, reconnaissance aircraft and seaplane designed in the late 1920s by the Plage i Laśkiewicz factory in Lublin. It was the first in-house design of Plage i Laśkiewicz, and the first with the name Lublin.
The WZ.X was the Polish reconnaissance aircraft designed in the mid-1920s and manufactured in the Centralne Warsztaty Lotnicze (CWL) - Central Aviation Workshops in Warsaw. It was the first combat aircraft of own design built in Poland, in a small series.
The Tupolev ANT-9 was a Soviet passenger aircraft of the 1930s. It was developed as a reaction to the demand for a domestic airliner. At this time Deruluft, one of the forerunners of Aeroflot, flew only with foreign models, which were mainly German or Dutch.
The Mikulin M-17 was a Soviet-licensed copy of the German BMW VI V-12 liquid-cooled aircraft piston engine, further developed by Alexander Mikulin and used by Soviet aircraft and tanks during World War II. Production began in 1930 and continued through 1942. More than 27,000 were produced, of which 19,000 were aircraft engines while the rest were used in Soviet tanks of the period.
The Blériot-SPAD S.46 was a small French airliner of the 1920s, developed from the Blériot-SPAD S.33. Like its predecessor, it was a conventional biplane that seated four passengers in an enclosed cabin while the pilot and occasionally a fifth passenger rode in an open cockpit. The S.46 had a redesigned wing of longer span and a far more powerful engine. The type was employed by Franco-Roumaine, which purchased 38 out of the 40 examples produced for use on their continental European routes.
The Blériot-SPAD S.61 was a French fighter aircraft developed in 1923. Designed by André Herbemont, the S.61 was a conventional biplane, abandoning the swept upper wing used by Herbemont in several previous designs. The prototype S.61 was evaluated by the French Air Force alongside the S.51 as a potential new fighter, but like its stablemate, was rejected. The Polish Air Force was impressed enough to order 250, as well as purchase licences for local production. The Romanian Air Force also ordered 100 aircraft. About 30 were built in Poland, by the CWL.
The Tupolev ANT-25 was a Soviet long-range experimental aircraft which was also tried as a bomber. First constructed in 1933, it was used by the Soviet Union for a number of record-breaking flights.
The Dewoitine D.1 was a French single-seat fighter aircraft of the 1920s, built by the French industrial company Dewoitine.
The Tupolev ANT-16 was an experimental heavy bomber aircraft designed and tested in the Soviet Union in the early 1930s.
The Tupolev I-8 was an experimental interceptor built in the Soviet Union in the early 1930s. It was the first Soviet aircraft to exceed 300 km/h in level flight. The aircraft was an exercise in developing the Polikarpov I-5 design by a group of engineers led by V. M. Rodionov, each of whom volunteered 70 hours of personal time to the project.
Tupolev TB-6 was a proposal by the Tupolev Design Bureau in the 1930s for a super-heavy bomber. Had it been built, it would have been the biggest-ever Soviet bomber and the largest aircraft by wingspan of its time, nine feet short of the 320 foot span of the Hughes H-4 Hercules, although the Scaled Composites Stratolaunch is now the biggest plane by wingspan.
The Yokosuka E1Y was a Japanese floatplane of the 1920s. A single-engined biplane that was designed and developed by the Yokosuka Naval Air Technical Arsenal as a reconnaissance aircraft for the Imperial Japanese Navy, 320 were built as the Type 14 Reconnaissance Seaplane, entering service in 1925 and remained in operational service until 1932.
The Tupolev ANT-41 was a prototype Soviet twin-engined torpedo-bomber of the 1930s. A single prototype was built, which was destroyed in a crash. No production followed, with the Ilyushin DB-3 serving as a torpedo bomber instead.
