| − | The '''{{Specs|name}}''' | + | The '''{{Specs|name}}''' was the second variant in the I-15 series of Soviet biplane fighters. Testing and acceptance trials began in July 1937, a year after the previous TsKB-3bis failed to meet the performance requirements. Just a few months later, the {{Specs|name}} entered service with the Soviet Air Force. Early models utilized the M-25 engine from the prior [[I-15 M-25]] until mass production of the more powerful M-25V engine became available in mid-1938. The aircraft was also quickly deployed in China during the Second Sino-Japanese War, where it outclassed the Japanese Kawasaki Ki-10 but struggled against monoplanes like the Mitsubishi A5M2a and Nakajima Ki-27. As time went on, new contenders in the constantly changing field of aerial combat emerged, including the Mitsubishi A6M Zero and the Messerschmitt Bf 109, and the I-15's limitations became obvious. It was quickly phased out as a fighter and assigned to less demanding roles, such as ground attack. A total of 2,408 {{Specs|name}} fighters were built between the autumn of 1937 and the end of 1939, making it the second most numerous variant of the I-15 family, just behind the I-153. |

The I-15 can be used in turnfighting, bomber intercepting and ground pounding. Like in AB and RB, it is excellent in turning tightly and continuously, and it has lovely low-speed handling and low stall speeds (unlike its successor I-16), making it a great starter plane for sim. However it does have its drawbacks: the rather big nose blocks the visibility a lot, offering very poor over-the-nose visibility which is a disadvantage in a turn fight, because when leading a shot the enemy will always get obstructed by the engine, making the player guess the shot. Also its upper wings will get in the way when you look aside. Plus, it has an awful telescope-like gunsight, so when zoomed in the I-15's nimbleness is magnified, making the aim super wobbly. You cannot see anything around which greatly reduces your situational awareness. | The I-15 can be used in turnfighting, bomber intercepting and ground pounding.

Description
The I-15bis was the second variant in the I-15 series of Soviet biplane fighters. Testing and acceptance trials began in July 1937, a year after the previous TsKB-3bis failed to meet the performance requirements. Just a few months later, the I-15bis entered service with the Soviet Air Force. Early models utilized the M-25 engine from the prior I-15 M-25 until mass production of the more powerful M-25V engine became available in mid-1938. The aircraft was also quickly deployed in China during the Second Sino-Japanese War, where it outclassed the Japanese Kawasaki Ki-10 but struggled against monoplanes like the Mitsubishi A5M2a and Nakajima Ki-27. As time went on, new contenders in the constantly changing field of aerial combat emerged, including the Mitsubishi A6M Zero and the Messerschmitt Bf 109, and the I-15's limitations became obvious. It was quickly phased out as a fighter and assigned to less demanding roles, such as ground attack. A total of 2,408 I-15bis fighters were built between the autumn of 1937 and the end of 1939, making it the second most numerous variant of the I-15 family, just behind the I-153.
The I-15bis was introduced in Update 1.31. It provides as a solid introduction to the tree as the first fighter in the line, prioritizing agility and depending primarily on getting its opponents in fights that it can easily win.

Survivability and armour
The I-15bis does not have significant armour protection. All the important modules are located in the front half of the fuselage, and the large fuel tank is not self-sealing. With all the important modules packed together, well aimed shots will have little trouble causing significant damage very quickly. As such, the I-15bis must rely on other factors, such as manoeuvrability, in order to increase its survivability.

Armaments
Offensive armament
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
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 manoeuvre 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.
Simulator:
The I-15 can be used in turnfighting, bomber intercepting and ground pounding. Like in AB and RB, it is excellent in turning tightly and continuously, and it has lovely low-speed handling and low stall speeds (unlike its successor I-16), making it a great starter plane for sim. However it does have its drawbacks: the rather big nose blocks the visibility a lot, offering very poor over-the-nose visibility which is a disadvantage in a turn fight, because when leading a shot the enemy will always get obstructed by the engine, making the player guess the shot. Also its upper wings will get in the way when you look aside. Plus, it has an awful telescope-like gunsight, so when zoomed in the I-15's nimbleness is magnified, making the aim super wobbly. You cannot see anything around which greatly reduces your situational awareness.
Note: it is recommended to set the convergence within 300 m, with vertical convergence on, because the majority of turnfights happen at that range or closer.
Note 2: in a turnfight you must get used to shooting without zooming in, as you really can't see anything with its awkward scope when zoomed it. However when tailing a straight-flying plane that scope doesn't seem that bad
Before engaging a fight, it is better to have an altitude advantage first. When approaching the fight try to figure out which is your teammate and which is the enemy, to avoid going for a second pass, as the energy retention of the I-15 is rather slow. Also pick your target carefully. For easier aiming, you want to go for those unmanoeuvrable twin engine aircraft like Ju 88 or Ki-45, or bombers if there are any. Given the bad forward visibility of the I-15, these are the best options as they are quite slow and sluggish, and are a bigger target to hit. However getting hits on them doesn't mean good damage, so you must be patient. When dealing with fighters, it is way harder to aim.

The small 50 kg bombs can be used on light pillboxes. Once the suspended armaments are gone, the 4 MG are good for killing soft targets like trucks, artillery and AA cars.
Enemies worth noting:
- Ki-27, N1K1, He 51, Gladiator, etc. - Those commonly seen planes are equally good at turnfights and will be a hard target to down since they are very small and agile. To deal with them you need to practice leading and deflection shots, plus manoeuvres like barrel rolls and scissors. They still need plenty of bullets to get damaged, so these kind of targets are the hardest to kill and requires great skills from the player.
- Do 17 Z-2 - This early twin engine plane always shows up as an AI controlled recon aircraft that you have to down, which is a good news as AI won't manoeuvre aggressively. However this plane is extremely durable for the I-15's weak MGs. When it shows up as an AI, deflection shots are not recommended as the small shooting windows really does nothing. Instead, try disabling its 2 gunners first, then just sit behind it and burst on its wings and engines.

Pros and cons
Pros:
- Decent firepower: 4 x 7.62 mm PV-1 MG has good destruction; with 3,050 rounds fire saturation is great even with low beginner's accuracy
- Amazing turnfighting capacities at almost all speed, making it one of the best turnfighters in-game
- Able to perform ground pounding: can carry 6 x rockets to destroy light tanks or even aircraft with timed fuses, or 2 x 50 kg bombs
- Lovely low stall speed and low speed handling, meaning it performs well in manoeuvres like spiral climb
- Fixed gear means that the player does not have to worry about extending/retracting gears in RB/SB
- Good rate of climb
- Small silhouette meaning you are harder to hit
- Very short take off distance
- Open cockpit allows you to easily hear nearby aircraft in Simulator
- Nose-mounted MGs means no need to worry about convergence distances
- Good manoeuvrability combined with fast rockets makes this aircraft lethal against both ground and air targets
Cons:
- Very slow speed: cannot keep up with early monoplane fighters (e.g. He 112) or even some bombers such as Do 17 E-1
- No combat flaps which limits its sharp-turning potential
- Awful gunsight for SB: too much zoom makes aiming very wobbly and frustrating
- Bad over-the-nose visibility makes turnfighting and leading hard in SB
- I-15bis's turn time is relatively higher compared to previous I-15s
- Will quickly lose speed gathered in a dive
- Average roll rate
- Side views are obstructed by the upper wings and supporting structures
- Very wobbly with Simulator controls, making it hard to aim precisely

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. | |
