The Tupolev I-4 was a Soviet sesquiplane single-seat fighter. It was conceived in 1927 by Pavel Sukhoi as his first aircraft design for the Tupolev design bureau, and was the first Soviet all-metal fighter.

Design and development

After the first prototype (under the development name Andrei Nikolayevich Tupolev fighter 5 | ANT-5), the I-4 was redesigned with a new engine cowling to decrease drag, with added rocket launchers on the upper wing and a larger tailfin. The lower wing was predominantly an attachment for the wing struts; it was almost removed in the second series, the I-4Z (where the lower wings were greatly shortened), and totally removed from the I-4bis, thus transforming the aircraft from a sesquiplane into a parasol-wing monoplane.

Operational history

The I-4 was used as a parasite fighter in experiments with the Tupolev TB-1 bomber. The aircraft was in Soviet service from 1928–1933. A total of 369 were built. [1]

The Tupolev Tu-70 was a Soviet passenger variant of the Tu-4 bomber, an unlicensed, reverse engineered copy of the Boeing B-29 Superfortress. Designed immediately after the end of World War II, it used a number of components from Boeing B-29s that had made emergency landings in the Soviet Union after bombing Japan. It had the first pressurized fuselage in the Soviet Union and first flew on 27 November 1946. The aircraft was successfully tested, recommended for serial production, but ultimately not produced because of more pressing military orders and because Aeroflot had no requirement for such an aircraft. A military cargo aircraft version was the Tupolev Tu-75.

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, OKB designation ANT-6, 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 one of the world's first cantilever wing four-engine heavy bombers. Despite obsolescence and being officially withdrawn from service in 1939, the TB-3 performed bomber and transport duties throughout much of World War II.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 is 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 Tupolev I-12 was a prototype Soviet fighter aircraft that never reached production. The I-12 was of unconventional design with twin booms made of water pipes containing recoilless rifles and two engines in a push-pull configuration. The aircraft first flew in 1931 but did not enter production due to disappointing performance and operational difficulties such as the inability for the pilot to escape the aircraft without hitting the propeller arc behind him. The second prototype from Tupolev was never completed.

The Tupolev ANT-40, also known by its service name Tupolev SB and development co-name TsAGI-40, was a high speed twin-engined three-seat monoplane bomber, first flown in 1934. The Tupolev design was advanced but lacked refinement, much to the dismay of crews, maintenance personnel, and Stalin, who pointed out that "there are no trivialities in aviation".

The Heinkel He 46 was a German World War II-era monoplane designed in 1931 for the close reconnaissance and army co-operation roles. While it served with the Luftwaffe's front-line units only briefly at the start of World War II, the He 46 served as late as 1943 as a nighttime nuisance bomber and with the Hungarian Air Force.

The ANT-3 was a Soviet all-metal aircraft designed by the Tupolev Design Bureau. Tupolev acquired much experience in building his first two aircraft, later using his experience to construct the ANT-3. By this time, Soviet Air Force leaders were convinced that metal was a highly usable substance in the building of airplanes. Tupolev therefore guided AGOS- TsAGI in creating the first Soviet all-metal aircraft. The ANT-3 was Tupolev's first practical aircraft.

<span class="mw-page-title-main">Grigorovich I-Z</span> Type of aircraft

The Grigorovich I-Z was a fighter aircraft developed in the Soviet Union during the 1930s. Advances in aircraft survivability thanks to all-metal construction and self-sealing and inert gas-filled fuel tanks led to experimentation with large-caliber weapons to shoot them down. In Soviet Union, Leonid Kurchevsky developed a series of recoilless rifles in various calibers and in 1930 was decided to adapt the 76.2 mm (3 in) weapons for aircraft use.

<span class="mw-page-title-main">Tupolev I-14</span> Type of aircraft

The Tupolev I-14 was a Soviet fighter aircraft of the 1930s. It was a single-engined, single-seat monoplane with retractable undercarriage, designed to carry heavy armament, and as such was one of the most advanced fighters of its time. It was ordered into production, but this was cancelled after only a small number had been built, the competing Polikarpov I-16 being preferred.

The Tupolev ANT-10 was a prototype single-engined light bomber/reconnaissance aircraft of the 1930s. Only a single example was built, the Polikarpov R-5 being preferred.

The Tupolev ANT-21 was a Soviet twin-engined four-seat heavy fighter, which also had the designation MI-3. It was not accepted for production, only two prototypes being built.

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.

The Polikarpov Ivanov was a 1930s prototype Soviet ground attack monoplane designed by Polikarpov for a soviet government procurement competition codenamed Ivanov.
