The I-15bis is a rank I Russian fighter with a battle rating of 1.0 (AB/RB/SB). It was introduced in Update 1.31.

General info

Flight performance

Describe how the aircraft behaves in the air. Speed, manoeuvrability, acceleration and allowable loads - these are the most important characteristics of the vehicle.

Survivability and armour

Examine the survivability of the aircraft. Note how vulnerable the structure is and how secure the pilot is, whether the fuel tanks are armoured, etc. Describe the armour, if there is any, and also mention the vulnerability of other critical aircraft systems.


Offensive armament

Main article: PV-1 (7.62 mm)

The I-15bis is armed with:

  • 4 x 7.62 mm PV-1 machine guns, nose-mounted (1,100 rpg upper + 425 rpg lower = 3,050 total)

Suspended armament

Main articles: FAB-50 (50 kg), RS-82, RBS-82

The I-15bis can be outfitted with the following ordnance:

  • Without load
  • 2 x 50 kg FAB-50 bombs (100 kg total)
  • 6 x RS-82 rockets
  • 6 x RBS-82 rockets

Usage in battles

Like other I-15 models, try not to go face-to-face against enemies and instead maneuvre around and dogfight the enemy from advantageous positions. With 3,050 rounds in the four machine guns, greater firing time can be afforded to lead shots into the enemy. As such, the aircraft is quite friendly to beginners with low gun accuracy.

Keep in mind the I-15bis has a slightly slower turn time than the preceding I-15 models. As such, be wary of rival biplanes that could begin out-turning the I-15bis.

The I-15bis can also equip six rockets, which can be used to ground-pound targets like light tanks or light-skinned vehicles, or activate the timed fuses and try to down larger aircraft like bombers, or even time it to destroy a fighter in a head-on.

Pros and cons


  • 4 x 7.62 mm PV-1 machine guns with 3050 shells gives good fire saturation even with low beginner's accuracy
  • Can carry six rockets to destroy light tanks or even aircraft with timed fuses
  • Turn time is quite good compared to monoplane aircraft


  • I-15bis's turn time is relatively higher compared to previous I-15s
  • Lower speed than other I-15


Describe the history of the creation and combat usage of the aircraft in more detail than in the introduction. If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the vehicle and adding a block "/ History" (example: https://wiki.warthunder.com/(Vehicle-name)/History) and add a link to it here using the main template. Be sure to reference text and sources by using <ref></ref>, as well as adding them at the end of the article with <references />. This section may also include the vehicle's dev blog entry (if applicable) and the in-game encyclopedia description (under === In-game description ===, also if applicable).

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.


Excellent additions to the article would be video guides, screenshots from the game, and photos.
