The '''{{Specs|name}}''' is a rank {{Specs|rank}} Soviet fighter {{Battle-rating}}. It was introduced in [[Update 1.81 "The Valkyries"]]. As of [[Update 1.89 "Imperial Navy"]], it is the last prop plane in the MiG/Polikarpov line and is one of the best prop fighters the Soviet Union has to offer.

The '''{{Specs|name}}''' was a proposed Soviet high altitude interceptor. It marked the conclusion of the I-220 series which was originally derived from the [[MiG-3-15|MiG-3]]. Compared to its predecessors, the {{Specs|name}} was both the heaviest and the most powerful. Additionally, it had a significantly improved Shchyerbakov pressure cabin, 8mm seat armour, and an arsenal of four synchronized 20mm ShVAK cannons. The {{Specs|name}} was designed to have a top speed of more than 700 km/h and a service ceiling of 12,000 meters, which made it capable of intercepting enemy aircraft at high altitudes. The second prototype, which is the one we have in the game, became the second fastest Soviet piston-engined fighter, only being surpassed by the Yak-3M. Despite its promising performance, the {{Specs|name}} faced too many delays as most of the work was focused on the I-250, and in the end, it ended up being overshadowed by other aircraft designs.

The {{Specs|name}} was introduced in [[Update 1.81 "The Valkyries"]]. It is one of the last piston fighters in the Soviet avation tree and is one of the best prop fighters the Soviet Union has to offer. It is best used at high altitudes, where its performance really shines and where it can outperform most of its contemporaries. But it's not a bad idea to only climb as much as you need to, because trying to dive straight on at enemies at lower altitudes can put the {{Specs|name}} at a disadvantage due to its high-speed compression.

The I-225 is the latest claim to the throne of Soviet prop-fighters. With its high speed at high altitudes, decent armament, good turning capabilities and insane climb rate, this Super-MiG is the best all-around dog-fighter Russia has to offer. Although relatively useless as an interceptor in real life, the I-225 is quite potent in War Thunder, being one of four Soviet props that are good at altitude, which is very unique for the Soviet tech tree that is mostly comprised of low-altitude prop planes. From take-off and into the fight, this MiG is an overall smooth operator and can be very competitive even when facing early jets.

* [[Spitfire F Mk 22]] and [[Spitfire F Mk 24|Mk 24]]. The extremely powerful Griffon engined Spitfires are some of the most dangerous enemies you will encounter at this BR. They possess an amazing climb rate, amazing roll rate, brutal acceleration, high speed, solid manoeuvrability and excellent high altitude performance. Their quad [[Hispano Mk.II (20 mm)|Hispano Mk II's]] can load a very potent "Air targets" belt which is filled with HEF-I and HEF-SAPI rounds that will shred your airframe to bits with a quick burst.

* [[Ta 152 H-1]]. While not a major enemy, it is possible to encounter the Ta 152 at higher altitudes where its engine performs the best. The outcome of the fight comes down to the more skilled pilot, as the two planes are fairly even performance-wise. Never let a Ta 152 get you in its gunsights, as it sports an incredibly powerful array of armaments that can shred through you like paper. You have a superior turning rate and energy retention but the 152 beats you in a dive, so focus on vertical manoeuvres.

Never try to outspeed them, they have brutal acceleration even without WEP, maintain their energy better than every prop plane and are a good 100 mph/200 kph faster than you.

The experimental high-altitude fighter/interceptor I-225 was created in the Mikoyan design bureau as part of work to develop new prototypes of fighter aircraft with new engines. The first experimental prototype was finished by May 9, 1944. The aircraft was designed to carry a powertrain consisting of a 2000 horsepower aircraft engine and a turbocharger. Its armament in comparison with previous prototypes was strengthened and consisted of four 20mm ShVAK cannons. In testing (primarily tests of the fighter's speed and altitude options) the aircraft showed impressive results: it could reach a speed of almost 560 km/h near the ground and 720 km/h at high altitude. Just two I-225s were built for testing purposes. For various reasons, both aircraft crashed in testing. After a range of improvements and upgrades, in March 1947 work on this project was stopped.

The I-225 was a proposed Soviet high altitude interceptor. It marked the conclusion of the I-220 series which was originally derived from the MiG-3. Compared to its predecessors, the I-225 was both the heaviest and the most powerful. Additionally, it had a significantly improved Shchyerbakov pressure cabin, 8mm seat armour, and an arsenal of four synchronized 20mm ShVAK cannons. The I-225 was designed to have a top speed of more than 700 km/h and a service ceiling of 12,000 meters, which made it capable of intercepting enemy aircraft at high altitudes. The second prototype, which is the one we have in the game, became the second fastest Soviet piston-engined fighter, only being surpassed by the Yak-3M. Despite its promising performance, the I-225 faced too many delays as most of the work was focused on the I-250, and in the end, it ended up being overshadowed by other aircraft designs.

The I-225 was introduced in Update 1.81 "The Valkyries". It is one of the last piston fighters in the Soviet avation tree and is one of the best prop fighters the Soviet Union has to offer. It is best used at high altitudes, where its performance really shines and where it can outperform most of its contemporaries. But it's not a bad idea to only climb as much as you need to, because trying to dive straight on at enemies at lower altitudes can put the I-225 at a disadvantage due to its high-speed compression.

The default belts of the ShVAK's are quite efficient and the cannons themselves are very accurate, so you should focus on performance upgrades. The most important upgrades are the engine, engine injection and then the survivability modules to help remedy the weak airframe of the I-225.

Your module research should look something like this:

  • Fuselage repair
  • Radiator
  • Compressor
  • Airframe
  • Wings repair
  • Engine
  • Engine injection
  • Cover
  • Offensive 20 mm
  • New 20 mm cannons

Armaments

Offensive armament

Weapon 14 x 20 mm ShVAK cannon
Ammunition400 rounds
Fire rate720 shots/min
Main article: ShVAK (20 mm)

The I-225 is armed with:

  • 4 x 20 mm ShVAK cannons, nose-mounted (100 rpg = 400 total)

The 20 mm ShVAK cannons are very accurate and are extremely powerful in controlled, well-aimed bursts to enemy wings and critical components. Your default belts are quite powerful and the cannons themselves are highly accurate due to the nose mountings. While most players recommend the "Ground Targets" belt, this is not necessarily the best choice when it comes to the I-225 thanks to the poor ballistics and damage output of the Soviet HEF and FI-T shell. The "Armoured Targets" belt contains three AP-I shell and one HEF shell, and this combination provides the best option as to start fires and damaging modules.

Usage in battles

The I-225 can be used to climb to bomber altitude (4-6 km) and act as an interceptor, and it can perform this role amicably with its good climb rate, high speed and fast-firing quad ShVAK 20 mm cannons that can start fires. Be wary that the I-225 has no bulletproof glass in the front to protect this pilot, so you should never tail any bomber and approach from oblique angles or force head-ons. Also its armament of four 20 mm can be lacking against large aircraft, so I-225 players will likely have to expend all of their ammo in a bomber if they want to bring it down.

If one either destroys all the bombers or there are no bombers to be found, you are free to fly as a fighter versus other fighters. When engaging fighters, primarily try to employ a Boom-&-Zoom or energy fighting tactics which are exceptionally great when performed at high altitudes. Versus less manoeuvrable planes such as the F8F-1B, you can potentially turn-fight but be careful to not lose too much energy, as you may struggle to regain it. Also avoid tunnel visioning, as the I-225's weakness is anything extended due to an increased chance that multiple enemies will engage you.

Offensive flying:

When offensively engaging an enemy, the pilot should use the amazing performance and superb dive speed to their advantage, as the I-225 is the most vulnerable when it is unable to use these traits. Your go-to flying style should be energy fighting or Boom-&-Zoom, as both of these rely on top speed, energy retention, diving speed, climb rate, and these areas are where the I-225 excels the most. Always make sure to be above your enemy so you maintain an energy advantage. Your ideal altitude is 6 km, as this is where you can make the most out of the powerful turbocharged AM-42 engine and abuse your insane dive speed to its potential.

Do not tail any bombers Due to the lack of bulletproof glass and the frail airframe, tailing a bomber is an invitation for a pilot snipe or destroyed engine of the attacker. Depending on the bomber, attacking from above or below from oblique angles is your best bet. Aim for the engines and the wings if you can't force a head-on.

Defensive flying:

An example of the Vertical Spiral, which the I-225 can make very good use of.

If an enemy manages to get on your tail or has you in their gunsights, you should enter a slight dive in order to make use of your amazing dive speed and excellent acceleration. Being an energy fighter, you can make use of energy-wasting manoeuvres such as spiral climbing, displacement rolls, Immelmann turns or vertical spirals. Vertical spirals are particularly effective thanks to your excellent energy retention.

Specific enemies worth noting

  • Spitfire F Mk 22 and Mk 24 - The extremely powerful Griffon engined Spitfires are some of the most dangerous enemies you will encounter at this BR. They possess an amazing climb rate, amazing roll rate, brutal acceleration, high speed, solid manoeuvrability and excellent high altitude performance. Their quad Hispano Mk II's can load a very potent "Air targets" belt which is filled with HEF-I and HEF-SAPI rounds that will shred your airframe to bits with a quick burst. Try to keep a higher altitude than it and dive on it if it's unaware of your presence. When one is engaging you, try to bleed its energy with vertical manoeuvres or if you're confident enough, you can turn fight it.
  • Bf 109 K-4 - The last of the legendary Bf 109's can also be encountered. You can outspeed it by a large margin and have superior acceleration and dive speed. Avoid employing an energy fighting playstyle as the K-4 has amazing energy retention and a solid climb rate, although the I-225 can take advantage of its strange refusal to stall when using WEP in order to beat the 109 in the vertical, although it is not recommended to use it in this way. Always remain on its tail and steer clear of its gunsights, as its powerful array of armaments (1 x 30 mm cannon or 3 x 20 mm cannons, both of which are loaded with the brutal Minengeschoß round) will down you quickly if they land a few good hits. Employ a Boom-&-Zoom playstyle to take advantage of your superior speed and high diving speed.
  • F8F-1B - The feared Bearcat is one of the best prop planes in the game and is the worst enemy for the I-225 to face, as the Bearcat outclasses it in practically every way aside from performance above 6 km. The Bearcat out-turns you, out-rolls you, out-climbs you, and has an extremely devastating set of AN/M3 cannons which are effectively Hispano Mk V's. Avoid them at all costs unless they are unaware of your presence, and if one forces an engagement on you, seek assistance from teammates.
  • Ta 152 H-1 - While not a major enemy, it is possible to encounter the Ta 152 at higher altitudes where its engine performs the best. The outcome of the fight comes down to the more skilled pilot, as the two planes are fairly even performance-wise. Never let a Ta 152 get you in its gunsights, as it sports an incredibly powerful array of armaments that can shred through you like paper. You have a superior turning rate and energy retention but the 152 beats you in a dive, so focus on vertical manoeuvres.

Manual engine controls can be used to counter the rapid overheating caused by using WEP. Following these instructions will allow you to use WEP indefinitely unless on a warm map.

  • Set the propeller pitch to 75%. Don't set it any lower as it will cause significant performance drop.
  • Set the oil radiator to 100% and the water radiator to 65%. While these values can be lowered at higher altitudes and colder maps, try to keep the oil temperature below 85°C and water temperature below 120°C.
  • On takeoff, set the mixture to 35% and keep it there until you reach an altitude of 4,000 m. Between 4,000 and 6,500 m set it to 25%. Between 6,500 and 8,500 m set it to 20%. Above 8,500 m switch back to auto engine control, as overheating is no longer an issue at extreme altitudes.
  • The supercharger and turbocharger are automatically controlled and require no player input.

Pros and cons

Pros:

  • Great low speed control and stall characteristics
  • Great energy retention, both in the vertical and while manoeuvring
  • Excellent high altitude performance
  • Great climb rate
  • Decent firepower
  • Powerful flaps
  • Great rudder effect

Cons:

  • Armament can sometimes feel inadequate against sturdy targets like bombers, low ammo count per gun
  • Severe elevator compression past ~650 km/h (IAS), and becomes a brick past 700 km/h
  • Engine prone to overheating, can be mitigated with use of MEC
  • Can face early jets (SB), which pose a huge challenge because of their high speeds
  • Lacks combat flaps, usage of takeoff flaps will bleed speed rapidly
  • Fairly fragile airframe that is susceptible to fires
  • Rudder effect is too great, it often overturns the plane
  • Below average manoeuvrability without flaps

History

The experimental high-altitude fighter/interceptor I-225 was created in the Mikoyan design bureau as part of work to develop new prototypes of fighter aircraft with new engines. The first experimental prototype was finished by May 9, 1944. The aircraft was designed to carry a powertrain consisting of a 2,000 horsepower aircraft engine and a turbocharger. Its armament in comparison with previous prototypes was strengthened and consisted of four 20 mm ShVAK cannons. In testing (primarily tests of the fighter's speed and altitude options) the aircraft showed impressive results: it could reach a speed of almost 560 km/h near the ground and 720 km/h at high altitude. Just two I-225s were built for testing purposes. For various reasons, both aircraft crashed in testing. After a range of improvements and upgrades, in March 1947 work on this project was stopped.

"During the early stages of the war on the Eastern Front, the German Ju-86P high altitude reconnaissance plane saw the Soviets lacking in a capable high altitude interceptor. Deeming it necessary to deal with these high altitude recon planes, an order went out for the creation of an interceptor that could fly high and fast enough to dispose of any intruders. The Mikoyan-Gurevich aircraft company, already successful with the high altitude MiG-3, took on the challenge to develop the fighter. The prototypes began development in 1942 as the I-220 series.

The I-225 the last of this series of aircraft. The I-225 was an improvement on the earlier I-220; compared to its predecessor the I-225 featured a pressurized cockpit, a cut down rear fuselage, and 4 synchronized 20 mm cannons firing through the propeller. The I-225 was powered by "a Mikulin AM-42B 12-cylinder liquid-cooled Vee engine equipped with a TK-300B turbo-supercharger on its starboard side and affording 2,000 hp for take-off and 1,750 hp at 7,500 m."

The all metal aircraft flew for the first time on the 21st of July, 1944. On August 2nd of the same year, the plane hit 707 km/h at an altitude of 8,500 m. During the 15th flight, the aircraft's engine seized at an altitude of 15 m and was deemed irreparable.

The second prototype and its tests were delayed until March 14th, 1945. The second I-225 was fitted with the AM-42-FB, an improvement on the first prototype's engine. This second prototype reached a speed of 726 km/h, one of the fastest speeds reached by any Soviet aircraft.

By the time of the I-225 the Germans had ceased high altitude operations rendering the existence of the plane largely unnecessary. However, development on high altitude aircraft continued thanks to the possibility of the Soviets going to war with the Western powers, who possessed heavy bombers that could operate well outside the effective operational altitudes of Soviet piston-engined planes.

Development on the I-225 and its brethren was ended in March 1947, when nobody saw a need for a high altitude interceptor and native Soviet jet designs were coming into service."
