In-game description

"A single-seat biplane fighter with a composite construction, open cockpit and fixed landing gear designed in N.N. Polikarpov's TsKB (Central Design Bureau). The plane was a modernized version of the I-15 fighter. The developmental prototype of the TsKB-3bis underwent state testing in July 1937, and went into series production in October of the same year at the No. 1 Aircraft Works in Moscow.

Apart from its new upper wing center section, increased fuel capacity and upgraded armament, the I-15bis differed from its predecessor in its new, longer engine housing, which not only covered the engine, but also the entire frontal section of the fuselage to the landing gear unit. Wind tunnel testing showed that this housing improved the plane's streamlining and increased its speed. A large semi-circular propeller spinner covering the plane's rotor head provided additional improvements to its aerodynamics. A ratchet passed through it for the self-starter.

The plane was equipped with the 750 hp 12-cylinder air-cooled M-25V radial engine (a licensed uprated version of the American Wright Cyclone SGR-1820 engine).

The plane's armament consisted of four synchronized 7.62 mm PV-1 machine guns (the “Pulemyot Vozdushnyj”, or “Airborne Machine Gun” was a reduced-weight model of the famous “Maxim” machine gun, redesigned with an air-cooled barrel and a disintegrating metal ammunition belt). The upper machine guns were equipped with 1,100 rounds each, and the lower guns – 425 rounds each. The rounds were housed in belts and located in the central fuselage directly behind the fuel tank. The used chain-link collectors were located in the same place. Spent cases were ejected outside and downwards.

In addition, the majority of series-produced I-15bis planes were equipped with four DER-31 bomb containers under the lower wing, rated for a maximum load of 150 kg (two FAB-50 bombs and two AO-25 bombs). Some of the planes were additionally equipped with four to six RO-82 launchers designed to fire RS-82 rockets. With the installation of the DER-32 bomb containers, it was also possible to install suspended VAP-6 spraying devices.

The I-15bis was in service with the USSR and China from the beginning of 1938 and with Spain from January 1939. It was used in Spain from February 1939. It participated in the Battles of Khalkhin Gol in May – September, and in the Winter War in the winter of 1939–1940. It saw use as a fighter and assault plane on the fronts of the Great Patriotic War in 1941–1942. Air defense logistics units used it right up to the end of 1944, particularly in the Far East. Production was ceased in 1939.

In total, 2408 I-15bis aircraft were built."
