The '''{{PAGENAME}}''' is a premium rank {{Specs|rank}} Soviet biplane {{Battle-rating}}. This fighter has been in the game since the start of the Open Beta Test prior to Update 1.29.

There is one thing you need to know about the I-153; you will out turn everything it fights. Not a single plane the Chaika fights will win against the I-153P in a turn fight. At a BR of 3.0, however, the Chaika's once moderate speed is now very bad. Nearly every plane will be faster; especially due to how the Chaika locks up at high speed, making it extremely difficult to maneuver at high speed. However, plenty of people underestimate the lowly Chaika, and attempt to turn with it. If you notice someone is trying to turn fight you, simply out turn them and light them up with 2 x 20 mm. However, bear in mind the Chaika is also more fragile than most planes in the game; a single 20 mm shot on it is almost always death.

=== Survivability and armour ===


* 8 mm Steel - Plating behind pilot's seat
* No armour glazing
* Critical components located at front of aircraft (fuel, pilot, engine, controls)

== Armaments ==
=== Offensive armament ===

{{main|ShVAK (20 mm)}}

The '''''{{PAGENAME}}''''' is armed with:

* 2 x 20 mm ShVAK cannon, nose-mounted (150 rpg = 300 total)

=== Suspended armament ===

{{main|FAB-50 (50 kg)|RS-82|RBS-82}}

The '''''{{PAGENAME}}''''' can be outfitted externally with:

* 4 x 50 kg FAB-50 bombs (200 kg total)
* 8 x 82 mm RS-82 rockets
* 8 x 82 mm RBS-82 rockets

== Usage in the battles ==

Not only can the Chaika be played as a turn fighter, but it is relatively effective as a bomber hunter. Since it can climb somewhat well, it can get up to bomber altitude and make an effort to stop them. With 2 x 20 mm, it has the ability to do significant damage to bombers. It also has 8 RS82 rockets, and when fired in a volley at a bomber, one of them is bound to make impact. All it takes is one to bring down even the mighty BV-238. As you face bombers, do NOT stay behind them for long. Their turrets will most likely shread you.

Not like other I-15 it have very few sells . .Also 20mm can easy destroy enemy.So it better you should shot accuracy

====Counter-tactics====

Should you be facing an I-153P, whatever you do, do not attempt to engage in a turn fight. The little biplane is more than capable of out turning even the A6M2 Reisen. Calmly deploy Boom & Zoom tactics against it; fly from an upper ground, light it up, and fly away. Try not to keep yourself level for too long, as there is a chance it will be able to hit you if you speed away. It has a moderate climbrate too and will climb after you with relative effectiveness if you fly back up after the "zoom".

=== In-game description ===
"The I-153P Chaika (Seagull) was a Soviet biplane fighter of the 1930s and 1940s. It was created by the Polikarpov Design Bureau in 1938. It is a modification (3rd variant) of the earlier I-15 fighter, as shown in the designation. The Chaika was considered to be the fastest biplane in the world. However, at the start of hostilities between the Soviet Union and Germany, the I-153 could not compete on equal terms with the German Messerschmitt Bf-109 and therefore was mainly used in ground attack roles.

For many years, Soviet pilots considered the I-16 to be the most dangerous aircraft in a spin. Therefore, when flight testing the I-153 with the M-25 engine in March and April of 1939, the VVS Command paid special attention to its spin characteristics. Initially, the matter remained unresolved. However, in the summer of 1939, when the new aircraft saw action against the Japanese in Mongolia, NII VVS returned to this crucial point. Test results were disappointing. By the third full rotation the I-153 would go into a flat spin; the engine would cease by the fifth formation, after which spin recovery would become extremely difficult. Lowering the landing gear in order to shift the center [sic] of gravity did not help. The Chaika still took a significant amount of time to recover."

With 6 rockets you can use I-15 to hunt big plane like bomber or attacker ,

Like other I15 you shouldn't face to face.Try to dogfight. But you have rockets , some time you can face to face. The I-15 bis turn drive is not very effective. So try to shot accuracy don't let the enmy can try back .7,62mm is not very good to destroy enemy with fewshot ,so at elast try to damage the enemy make him hard to turn .

Like other I-15.Wwth 3050 shells you can shot with low accuracy .If you are learning to shot is can be a good choice . But it better you should use if your shoting skill is not very bad because it not good to dogfight

''Summarise and briefly evaluate the vehicle in terms of its characteristics and combat effectiveness. Mark its pros and cons in the bulleted list. Try not to use more than 6 points for each of the characteristics. Avoid using categorical definitions such as "bad", "good" and the like - use substitutions with softer forms such as "inadequate" and "effective".''

'''Pros'''

4 x 7.62 mm PV-1 machine guns with 3050 shells.It have the aircaft have most shells of RAnkI and Bplane. You can shot with low accuracy .If you are learning to shot. It is a good coice

Can carry 6 RS-82 6 RBS rocket you can destroy light tank or shot down aircaft with 1 shot .When you attack enemy bomber you mustuse lost of shell and mabe get shot down by enemy turret . With 1 shot accuracy you can shot down the aircaft

Turn drive is quite good

*

'''Cons:'''

Also is a I-15 but it need 10 s to turn (other just 8s) ,can turn better than one wing aircaft(Bf 109,He 112,P 36) or some B plane . But is worst than other I-15 and lots of BPlane. So it not effctive to dogfight like other I-15 .

Lower speed than other I-15

=== 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.

== Description ==

[[File:GarageImage_{{PAGENAME}}.jpg|420px|thumb|left]]
{{break}}
The '''{{Specs|name}}''' is a rank {{Specs|rank}} Russian fighter {{Battle-rating}}. It has been in the game since the start of the Open Beta Test prior to Update 1.27.

The I-15 R is a single-engine fighter developed from the OKB Polikarpov I-15 (TsKB-3) for a 1935 release. Attempt to introduction the Soviet license modification of the Wright Cyclone SGR-1820 engine under the designation M-25 was progressing very slowly, therefore most of the production I-15 aircraft at this time were outfitted with the 9-cylinder Gnome et Rhône air-cooled M-22 engines (the licensed version of the British Bristol Jupiter VI) which had a nominal power of only 480 hp, which caused this aircraft’s flight performance to suffer.
While on the final production series of this aircraft the M-25 engines were installed, this version of the aircraft in-game features the weaker M-22 engine.

== General info ==
=== Flight Performance ===


The I-15 M-22 has decent performance as a reserve fighter even with the lacklustre M-22 engine. This aircraft will often get into aerial engagements averaging with a 1.0 battle rating, however, the I-15 M-22 can still be a formidable machine, even in the hands of a novice:

* Rate of climb - Among the reserve aircraft, the I-15 does not have the best performance in climb rate, but because early matches consist of low-level dog-fights which take place at +/- the same height, this is not an issue.
* The top speed of this fighter is not a record characteristic of the “Seagulls”. While it is possible to catch up to and overtake the German He.51, most of the other remaining reserve aircraft are superior to this Soviet fighter, especially aircraft reaching into the Battle ratings of 1.3-2.0,
* While lacking advantages with speed and rate of climb, manoeuvrability is one of the best advantages in the game for this aircraft in early matches. In fact, due to the quick turn time, the “Seagull” pilot is able to outmanoeuvre many other early aircraft in the game.

=== Survivability and armour ===


Early attempts to protect the pilot outfitted the aircraft with a 9-mm armoured backrest. Although many of the planes encountered in early battles and other I-15s do not have any armour at all, the survivability of the Seagull leaves much to be desired - unprotected fuel tanks can catch fire while fragile wings and fuselage can easily detach from a relatively short burst of a machine gun or cannon fire. Owing to an inefficient cooling system, the player is forced to make full use of the manoeuvrability of the aircraft.

== Armaments ==
=== Offensive armament ===

{{main|PV-1 (7.62 mm)}}

The '''''{{PAGENAME}}''''' is armed with:

* 4 x 7.62 mm PV-1 machine guns, nose-mounted (750 rpg = 3,000 total)

The I-15 is armed with 4 x PV-1 machine guns with a total ammunition load of 3,000 rounds. The damage dealt from these machine guns is not bad, especially against biplanes and early wooden monoplanes, however, with opponents having a greater battle rating, the pilot will need to test different options to see what works best for them. Recommended belts for this aircraft are either universal or tracers. While using an all tracer belt does not seem as powerful as the universal belt, they are extremely effective against early aircraft by lighting fuel tanks on fire, knocking out pilots and are extremely easy to use for new pilots as they will be able to see where all of their rounds are going and adjust fire to compensate when necessary. For the advanced pilot who wants to exercise the element of surprise, Stealth belts are the way to go.
=== Suspended armament ===

{{main|FAB-50 (50 kg)}}

The '''''{{PAGENAME}}''''' can be outfitted with the following ordnance:

* Without load
* 2 x 50 kg FAB-50 bombs (100 kg total)

Under the wings of the "Seagull", you can hang 2 x 50 kg FAB-50 bombs. Choices are very limited with early aircraft due to the amount of weight they can haul. Overall bomb damage is mediocre, requiring the pilot to drop their ordnance exactly on the enemy vehicles to maximize the chance for destruction or at the least, disabling of the vehicle. This aircraft is not meant to be a bomber, however, it does have the opportunity selectively take out soft targets on the battlefield such as mobile anti-aircraft vehicles and anti-aircraft artillery sites.

== Usage in battles ==

In aerial realistic battles, the use of gulls is very simple - removing the enemy fighters chasing the tail of allied fighters who failed to gain altitude. Doing so can make a high contribution to the development of the battle and seriously influence its outcome. During tank battles, the “Seagull” pilot can utilise the FAB-50 bombs to attack softer enemy armoured vehicles (if you practice, you can learn how to drop bombs accurately), and with the help of machine guns you can destroy equipment with open tops, exposed crews and various anti-aircraft guns and self-propelled guns from enemy air attacks.

I-15 is not bad for beginners who have just begun to master aviation - excellent manoeuvrability and good armament provide high chances for success in shooting down the enemy in frequent “Dogfights” in the lower battle rated matches. The main thing to remember for the I-15 pilot is the inefficient cooling system - even on winter maps, the plane is prone to overheating when continuously using the engine at 100%. Outside the active combat phase, it is better to lower the flight power to between 92-95% to preserve your engine for when you really need it.

It can be easy to destroy. So you shouldn't solo 1vs1 face to face with enemy. Turn and turn drive to dogfight.

With 3000 shells. YOu can shot with low accuracy . If you learning to shot it is a swesomechoice.

'''Pros:'''

* Excellent manoeuvrability.You can easy destroy all Rank I and many rank II aircaft in dogfight (if you are not get damage and just dogfight with 1-2 aircaft)
* Good weapons
* A lost of 7,62 mm( 3000 Shells) . You can shot with lower accuracy .If you are learning to shot it is a awesome choice.

'''Cons:'''

* Inefficient cooling system

== History ==

[[File:I-15_Chaika_Captured_by_German_Army.jpg|350px|thumb|right|An image of an [[I-15 (Family)|I-15]] captured by the advancing German Army at Prushany in 1941 during Operation Barbarossa.]]
The aircraft was initially developed in 1933 as a further development of the I-5 and I-6 with a specific focus in improving aerodynamics. On the first production aircraft set, the I-15 WR utilised the Wright Cyclone SGR-1820 F-3 engine which had a nominal power of 630 hp on the ground. In 1934 there was still no serial M-25 Soviet licensed engine, so the less powerful M-22 had to be installed (the licensed version of the Bristol Jupiter) - several hundred copies of them were produced in 1934-1936. In 1935, the aircraft was adopted by the Red Army Air Force as their premier combat aircraft. In 1936, only 12 combat vehicles were manufactured, however, in 1937, the I-15 went to serial production with the new M-25 engines. In the 30s, the aircraft had no equal manoeuvrability on the horizontal (8-8.5 s. turning time), was stable in all flight modes, easy to fly and had good takeoff and landing qualities. In the words of Colonel E. N. Stepanov, who fought with this aircraft in Spain and committed the world's first night ramming with the I-15 stated that “it is possible with a certain skill to catch up with your tail in a turn”. This aircraft had good repair properties and vitality.

Further development of the I-15 became the I-15bis and I-153 "Seagull."

The good rate of climb of the I-15 allowed it to be used as a high-altitude fighter. On the first prototype of the I-15, after special training (maximally facilitating the construction and installation of a Wright Cyclone F-54 high-altitude engine), pilot V.K. Kokkinaki on November 21, 1935 exceeded the absolute world record of flight altitude, gaining 14,575 meters, unfortunately, it wasn’t until 1936 that Soviet FAI records were recorded. Since 1937, work began on equipping the I-15 with a pressurized cabin, which made it possible to make fuller use of the height characteristics. The I-15GK and I-153GK were tested with Shcherbakov's cabin and several Polikarpovskiy’s less successful I-15V variants. All variants with a pressurized cabin remained only in experimental status and never went into production.
Combat use:

* 1936 – 1939 The Spanish Civil War - Used under the name Chato as a fighter, attacker, and reconnaissance aircraft. In total, 368 aircraft of this type were used in Spain. This fighter went down in history as one of the best fighters in the world during this period of time.

* 1937 Second Sino-Japanese War – Used as a fighter. The I-15 worked together with the I-16 and utilised their talents with high-speed and manoeuvrability to shine in combat. In the summer of 1938, it was used in battles at Lake Hassan. 1939 - fighting in Mongolia on the Khalkhin Gol River, again was used as a fighter aircraft in conjunction with the I-16. Time was catching up to the I-15 as during battles with Japanese fighters it showed to have lost its manoeuvrability advantage and was starting to be bested by modern Japanese fighters.

* 1941 - Used at the beginning of the Great Patriotic War.

* 1947 - 1948 - Mongolian-Chinese border conflict, as well as the Mongolian-Eastern Turkestan border conflict.

=== In-game description ===
Polikarpov I-15 (TsKB-3) single-engine fighter, produced in 1935

The launch of the Soviet licensed version of the Wright Cyclone SGR-1820 engine, under the designation M-25, was quite drawn out; therefore, a majority of production I-15s were equipped with M-22 (a licensed version of the British Bristol Jupiter VI) nine-cylinder, air-cooled engines, whose rated power was only 480 hp. This significantly worsened the plane's flight characteristics.

Aircraft from the final production series had M-25 engines. In addition, they had one more pair of 7.62 mm synchronous PV-1 machine guns.

Most I-15s had fixed-pitch propellers, but some machines received VISh-6 controllable-pitch propellers.

In Spain, in the autumn of 1936, the I-15 fighter was used for the first time in the field. The first air battle involving an I-15 took place on November 4. A total of 186 I-15 fighters were received by the Republicans from the USSR.

I-15 fighters were also used in the Khalkhyn Gol frontier conflict, in the Winter War of 1939-40, and even during the initial period of World War II (mainly as ground-attack aircraft). However, the plane was considered obsolete even by the Battle of Khalkhyn Gol.

Stable and handy, with good flight characteristics, exceptional manoeuvrability, and excellent takeoff/landing parameters, the I-15 fighter enjoyed a well-deserved success among pilots.

Some I-15 fighters were used as personal command vehicles. For example, a drawing of a flying red banner with the words "FOR VKP (B)", i. e. "For the All-Union Communist Party (of Bolsheviks)", was applied to the fuselage of the personal I-15 of Brigade Commander I. U. Pavlov, and a bent white arrow directed down was painted on the red rudder. The metal skin of the nose fuselage was polished in a frost pattern.

On November 21, 1935, the test pilot V. K. Kokkinaki established the world's unofficial (as the USSR was not yet a member of the FAI) flight altitude record of 14,575 m while flying a special TsKB-3 with a reduced weight.

The I-15's manoeuvrability was excellent, and its short fuselage and large control surfaces ensured the fighter's agility. Not a single major rival of the I-15 in Spain (neither the German He 51 fighter nor the Italian CR.32) was its equal in these characteristics.

The I-15's full-scale production was discontinued in 1936. A total of 384 aircraft were manufactured at Factories No. 1 and No. 39 from 1934-36. In addition, 291 more aircraft were built under licence in Republican Spain.

'''Pros'''

4 x 7.62 mm PV-1 machine guns with 3050 shells.It have the aircaft have most shells of RAnkI and Bplane. You can shot with low accuracy .If you are learning to shot. It is a good coice

Can carry 6 RS-82 6 RBS rocket you can destroy light tank or shot down aircaft with 1 shot .When you attack enemy bomber you mustuse lost of shell and mabe get shot down by enemy turret . With 1 shot accuracy you can shot down the aircaft

Turn drive is quite good

*

'''Cons:'''

Also is a I-15 but it need 10 s to turn (other just 8s) ,can turn better than one wing aircaft(Bf 109,He 112,P 36) or some B plane . But is worst than other I-15 and lots of BPlane. So it not effctive to dogfight like other I-15 .

Lower speed than other I-15

=== 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.

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.

== Description ==

[[File:GarageImage_{{PAGENAME}}.jpg|420px|thumb|left]]
{{break}}
The '''{{Specs|name}}''' is a rank {{Specs|rank}} Russian fighter {{Battle-rating}}. It has been in the game since the start of the Open Beta Test prior to Update 1.27.

The I-15 R is a single-engine fighter developed from the OKB Polikarpov I-15 (TsKB-3) for a 1935 release. Attempt to introduction the Soviet license modification of the Wright Cyclone SGR-1820 engine under the designation M-25 was progressing very slowly, therefore most of the production I-15 aircraft at this time were outfitted with the 9-cylinder Gnome et Rhône air-cooled M-22 engines (the licensed version of the British Bristol Jupiter VI) which had a nominal power of only 480 hp, which caused this aircraft’s flight performance to suffer.
While on the final production series of this aircraft the M-25 engines were installed, this version of the aircraft in-game features the weaker M-22 engine.

== General info ==
=== Flight Performance ===


The I-15 M-22 has decent performance as a reserve fighter even with the lacklustre M-22 engine. This aircraft will often get into aerial engagements averaging with a 1.0 battle rating, however, the I-15 M-22 can still be a formidable machine, even in the hands of a novice:

* Rate of climb - Among the reserve aircraft, the I-15 does not have the best performance in climb rate, but because early matches consist of low-level dog-fights which take place at +/- the same height, this is not an issue.
* The top speed of this fighter is not a record characteristic of the “Seagulls”. While it is possible to catch up to and overtake the German He.51, most of the other remaining reserve aircraft are superior to this Soviet fighter, especially aircraft reaching into the Battle ratings of 1.3-2.0,
* While lacking advantages with speed and rate of climb, manoeuvrability is one of the best advantages in the game for this aircraft in early matches. In fact, due to the quick turn time, the “Seagull” pilot is able to outmanoeuvre many other early aircraft in the game.

=== Survivability and armour ===


Early attempts to protect the pilot outfitted the aircraft with a 9-mm armoured backrest. Although many of the planes encountered in early battles and other I-15s do not have any armour at all, the survivability of the Seagull leaves much to be desired - unprotected fuel tanks can catch fire while fragile wings and fuselage can easily detach from a relatively short burst of a machine gun or cannon fire. Owing to an inefficient cooling system, the player is forced to make full use of the manoeuvrability of the aircraft.

== Armaments ==
=== Offensive armament ===

{{main|PV-1 (7.62 mm)}}

The '''''{{PAGENAME}}''''' is armed with:

* 4 x 7.62 mm PV-1 machine guns, nose-mounted (750 rpg = 3,000 total)

The I-15 is armed with 4 x PV-1 machine guns with a total ammunition load of 3,000 rounds. The damage dealt from these machine guns is not bad, especially against biplanes and early wooden monoplanes, however, with opponents having a greater battle rating, the pilot will need to test different options to see what works best for them. Recommended belts for this aircraft are either universal or tracers. While using an all tracer belt does not seem as powerful as the universal belt, they are extremely effective against early aircraft by lighting fuel tanks on fire, knocking out pilots and are extremely easy to use for new pilots as they will be able to see where all of their rounds are going and adjust fire to compensate when necessary. For the advanced pilot who wants to exercise the element of surprise, Stealth belts are the way to go.
=== Suspended armament ===

{{main|FAB-50 (50 kg)}}

The '''''{{PAGENAME}}''''' can be outfitted with the following ordnance:

* Without load
* 2 x 50 kg FAB-50 bombs (100 kg total)

Under the wings of the "Seagull", you can hang 2 x 50 kg FAB-50 bombs. Choices are very limited with early aircraft due to the amount of weight they can haul. Overall bomb damage is mediocre, requiring the pilot to drop their ordnance exactly on the enemy vehicles to maximize the chance for destruction or at the least, disabling of the vehicle. This aircraft is not meant to be a bomber, however, it does have the opportunity selectively take out soft targets on the battlefield such as mobile anti-aircraft vehicles and anti-aircraft artillery sites.

== Usage in battles ==

In aerial realistic battles, the use of gulls is very simple - removing the enemy fighters chasing the tail of allied fighters who failed to gain altitude. Doing so can make a high contribution to the development of the battle and seriously influence its outcome. During tank battles, the “Seagull” pilot can utilise the FAB-50 bombs to attack softer enemy armoured vehicles (if you practice, you can learn how to drop bombs accurately), and with the help of machine guns you can destroy equipment with open tops, exposed crews and various anti-aircraft guns and self-propelled guns from enemy air attacks.

I-15 is not bad for beginners who have just begun to master aviation - excellent manoeuvrability and good armament provide high chances for success in shooting down the enemy in frequent “Dogfights” in the lower battle rated matches. The main thing to remember for the I-15 pilot is the inefficient cooling system - even on winter maps, the plane is prone to overheating when continuously using the engine at 100%. Outside the active combat phase, it is better to lower the flight power to between 92-95% to preserve your engine for when you really need it.

It can be easy to destroy. So you shouldn't solo 1vs1 face to face with enemy. Turn and turn drive to dogfight.

With 3000 shells. YOu can shot with low accuracy . If you learning to shot it is a good choice.

== History ==

[[File:I-15_Chaika_Captured_by_German_Army.jpg|350px|thumb|right|An image of an [[I-15 (Family)|I-15]] captured by the advancing German Army at Prushany in 1941 during Operation Barbarossa.]]
The aircraft was initially developed in 1933 as a further development of the I-5 and I-6 with a specific focus in improving aerodynamics. On the first production aircraft set, the I-15 WR utilised the Wright Cyclone SGR-1820 F-3 engine which had a nominal power of 630 hp on the ground. In 1934 there was still no serial M-25 Soviet licensed engine, so the less powerful M-22 had to be installed (the licensed version of the Bristol Jupiter) - several hundred copies of them were produced in 1934-1936. In 1935, the aircraft was adopted by the Red Army Air Force as their premier combat aircraft. In 1936, only 12 combat vehicles were manufactured, however, in 1937, the I-15 went to serial production with the new M-25 engines. In the 30s, the aircraft had no equal manoeuvrability on the horizontal (8-8.5 s. turning time), was stable in all flight modes, easy to fly and had good takeoff and landing qualities. In the words of Colonel E. N. Stepanov, who fought with this aircraft in Spain and committed the world's first night ramming with the I-15 stated that “it is possible with a certain skill to catch up with your tail in a turn”. This aircraft had good repair properties and vitality.

Further development of the I-15 became the I-15bis and I-153 "Seagull."

The good rate of climb of the I-15 allowed it to be used as a high-altitude fighter. On the first prototype of the I-15, after special training (maximally facilitating the construction and installation of a Wright Cyclone F-54 high-altitude engine), pilot V.K. Kokkinaki on November 21, 1935 exceeded the absolute world record of flight altitude, gaining 14,575 meters, unfortunately, it wasn’t until 1936 that Soviet FAI records were recorded. Since 1937, work began on equipping the I-15 with a pressurized cabin, which made it possible to make fuller use of the height characteristics. The I-15GK and I-153GK were tested with Shcherbakov's cabin and several Polikarpovskiy’s less successful I-15V variants. All variants with a pressurized cabin remained only in experimental status and never went into production.
Combat use:

* 1936 – 1939 The Spanish Civil War - Used under the name Chato as a fighter, attacker, and reconnaissance aircraft. In total, 368 aircraft of this type were used in Spain. This fighter went down in history as one of the best fighters in the world during this period of time.

* 1937 Second Sino-Japanese War – Used as a fighter. The I-15 worked together with the I-16 and utilised their talents with high-speed and manoeuvrability to shine in combat. In the summer of 1938, it was used in battles at Lake Hassan. 1939 - fighting in Mongolia on the Khalkhin Gol River, again was used as a fighter aircraft in conjunction with the I-16. Time was catching up to the I-15 as during battles with Japanese fighters it showed to have lost its manoeuvrability advantage and was starting to be bested by modern Japanese fighters.

* 1941 - Used at the beginning of the Great Patriotic War.

* 1947 - 1948 - Mongolian-Chinese border conflict, as well as the Mongolian-Eastern Turkestan border conflict.

=== In-game description ===
Polikarpov I-15 (TsKB-3) single-engine fighter, produced in 1935

The launch of the Soviet licensed version of the Wright Cyclone SGR-1820 engine, under the designation M-25, was quite drawn out; therefore, a majority of production I-15s were equipped with M-22 (a licensed version of the British Bristol Jupiter VI) nine-cylinder, air-cooled engines, whose rated power was only 480 hp. This significantly worsened the plane's flight characteristics.

Aircraft from the final production series had M-25 engines. In addition, they had one more pair of 7.62 mm synchronous PV-1 machine guns.

Most I-15s had fixed-pitch propellers, but some machines received VISh-6 controllable-pitch propellers.

In Spain, in the autumn of 1936, the I-15 fighter was used for the first time in the field. The first air battle involving an I-15 took place on November 4. A total of 186 I-15 fighters were received by the Republicans from the USSR.

I-15 fighters were also used in the Khalkhyn Gol frontier conflict, in the Winter War of 1939-40, and even during the initial period of World War II (mainly as ground-attack aircraft). However, the plane was considered obsolete even by the Battle of Khalkhyn Gol.

Stable and handy, with good flight characteristics, exceptional manoeuvrability, and excellent takeoff/landing parameters, the I-15 fighter enjoyed a well-deserved success among pilots.

Some I-15 fighters were used as personal command vehicles. For example, a drawing of a flying red banner with the words "FOR VKP (B)", i. e. "For the All-Union Communist Party (of Bolsheviks)", was applied to the fuselage of the personal I-15 of Brigade Commander I. U. Pavlov, and a bent white arrow directed down was painted on the red rudder. The metal skin of the nose fuselage was polished in a frost pattern.

On November 21, 1935, the test pilot V. K. Kokkinaki established the world's unofficial (as the USSR was not yet a member of the FAI) flight altitude record of 14,575 m while flying a special TsKB-3 with a reduced weight.

The I-15's manoeuvrability was excellent, and its short fuselage and large control surfaces ensured the fighter's agility. Not a single major rival of the I-15 in Spain (neither the German He 51 fighter nor the Italian CR.32) was its equal in these characteristics.

The I-15's full-scale production was discontinued in 1936. A total of 384 aircraft were manufactured at Factories No. 1 and No. 39 from 1934-36. In addition, 291 more aircraft were built under licence in Republican Spain.
