General info

Flight performance

Equipped with a 2,000 hp engine, this aircraft's performance is on par with that of the legendary P-51 Mustang. However, unlike the Mustang, the Ki-84 has slightly better turning characteristics and climb rate thanks to its lighter weight. This being said, the Ki-84 also has good energy retention, so try to make your opponent bleed energy to have an edge. The Ki-84 was also one of the first mass-produced Japanese aircraft to come equipped with armoured glass, armour plates and self-sealing fuel tanks, but the armour is still lacklustre compared to its Russian and American counterparts. However, as always, not everything is perfect. The aircraft controls stiffen significantly at speeds above 630 km/h, making even slight adjustments to heading impossible. Thus, at higher speeds, its elevator suffers. The Ki-84 also suffers a lot when no modules are researched, making the aircraft almost useless until modifications are unlocked.

This aircraft should be played as it appears: a lightweight Japanese version of the Mustang, retaining good engine performance, decent climb-rate, high diving performance, but relatively lacklustre armament.

Usage in battles

RB:

The strong rate of climb of this fighter allows for a significant altitude advantage to be made in the beginning of battles. As this fighter is usually paired with the Soviets against the Japanese, make sure to utilise this advantage as your Soviet teammates and many of the Japanese fighters that you will encounter will be unable to climb as high as you. However, if German aircraft are present in the opposing team be cautious of climbing too high as they will be able to easily gain an altitude advantage over you.

When encountering Japanese Zeroes (i.e. the A6M5) do not attempt to "turn-fight" them. Instead, maintain your energy with a typical boom and zoom technique as they will be unable to match your altitudes. The N1K2 series and the Bf 109 series have greater rates of climb, but handle slightly worse at lower speeds, hence it is suggested that you should attempt to burn both your opponent's and your own energy using climbing corkscrew manoeuvres to bring both of you into your optimal fighting altitude (~4,000 m) at your best operating speed (< 400 km/h). Here you are more manoeuvrable and have a better chance at taking out these fast aircraft.

Due to your fairly weak weaponry, it is not advised to chase after heavily armoured bombers and instead focus on fighting enemy fighters. A potential approach is to support allied aircraft by maintaining a high altitude above them, preventing enemy aircraft from diving on top of your allies as you can control the airspace directly above them.

Pros and cons

Pros:

• Strong rate of climb compared to other fighters such as the Ki-61 series and the A7M2
• Effective top speed and energy retention allowing for the effective use of "boom and zoom" tactics
• Great acceleration allowing speed to be regained quickly after duels
• Reasonable performance at high altitude
• Maintains a high degree of manoeuvrability at lower speeds
• Jack of all trades: nimble yet quick while having a good degree of energy retention, allows this fighter to hold its own against any fighter that it may encounter
• Thanks to its lack of canopy frames, a clear all-round canopy view especially over the nose gives it a huge advantage in simulator.

Cons:

• Not as manoeuvrable as the Japanese fighters that you will be facing at this tier, and struggles to contest the high altitudes of the Bf 109 series due to their superior rates of climb
• The "jack of all trades, master of none" character of this aircraft makes it difficult to play as pilots will need to adapt their play-style to counter specific aircraft that they are facing, subsequently requiring a fair degree of knowledge over the strengths and weaknesses of each aircraft that they will encounter
• The weapons feel fairly lacklustre, with the 20 mm cannons having a reasonably low amount of ammunition (at least compared to the 12.7 mm machine guns)
• Severe lock-up of the rudder above 500 km/h renders dive bombing or high speed boom and zoom less effective
• Elevator locks up at high speeds preventing optimal usage of its great energy retention
• A reasonably slow roll-rate causing this fighter to be vulnerable against Japanese fighters or the Fw 190's which are the typical opponents
• Fairly susceptible to damage with fires being particularly devastating to this light aircraft

History

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).

Media

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