|This page is about the Japanese fighter Ki-84 ko. For other versions, see Ki-84 (Family).|
The Ki-84 ko Hayate is a rank IV Japanese fighter with a battle rating of 4.7 (AB), 5.3 (RB), and 5.0 (SB). It was introduced in Update 1.37.
The Ki-84 ko is the first truly fast aeroplane in the Japanese tech tree. 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
Describe the tactics of playing in the aircraft, the features of using aircraft in a team and advice on tactics. Refrain from creating a "guide" - do not impose a single point of view, but instead, give the reader food for thought. Examine the most dangerous enemies and give recommendations on fighting them. If necessary, note the specifics of the game in different modes (AB, RB, SB).

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 If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the vehicle and adding a block "/History" (example: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).
Excellent additions to the article would be video guides, screenshots from the game, and photos.
Links to the articles on the War Thunder Wiki that you think will be useful for the reader, for example:
- reference to the series of the aircraft;
- links to approximate analogues of other nations and research trees.
Paste links to sources and external resources, such as:
- topic on the official game forum;
- encyclopedia page on the aircraft;
- other literature.
