Description

The Ki-84 ko Hayate is a Rank IV Japanese fighter with a battle rating of 6.0 (AB), 5.3 (RB), and 5.0 (SB). It was introduced in Update 1.37.

The Ki-84 ko is the first truly fast airplane 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 armored glass, armor plates and self sealing fuel tanks, but the armor is still lackluster, compared to its Russian and American counterparts. However, as always, not everything is perfect. The aircraft's controls stiffer significantly at speeds above 630 kp/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 and relatively lackluster armament.

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 If the historical reference turns out to be too big, take it to a separate article, taking a link to an article about the vehicle and adding a block "/ historical reference" (example: https://wiki.warthunder.com/Name-vehicles/historical reference) and add a link to it here using the main template. Be sure to include links to sources at the end of the article.

Media

An excellent addition to the article will be video guides, as well as screenshots from the game and photos.
