General info

Flight performance

This aircraft is typical of Japanese fighter design: light armour and tight maneuverability. This aircraft can out-turn most other fighters of rank 1-2. It dances away from the line of fire with extreme agility, and can strike from high angles with ease.

Survivability and armour

Typical of low-rank Japanese fighter design, this aircraft has no armour. Due to this, most calibres found in ranks 1 and 2 will make quick work of this plane. Don't let this sway you away from this plane, it makes up for its lack of armour with extreme maneuverability. The fuel tanks are not self-sealing. There are 2 in each wing, and a 5th one located close to the oil cooling system.

Armaments

Offensive armament

The Ki-27 otsu (China) is armed with:

• 2 x 7.7 mm Type 89 army machine guns, nose-mounted (500 rpg = 1,000 total)

Usage in battles

A superior dogfighter for turn-fighting, the Ki-27 is the first plane to begin showing the features typical of the Japanese "Zero" but with none of the bite. Its speed and manoeuvrability are plagued by engine problems, with no armour and a standard armament.

In battle, no Allied fighter can out-turn you, except for biplanes, but most will outgun you (and even most biplanes match the Ki-27 in armament).

Biplanes (except the I-153 Chaika) make easy prey for the Ki-27, and the Ki-27 can easily outmanoeuvre the P-36 Hawk, the F2A Brewster Buffalo and the I-16 Ishak, but their stronger armaments will knock out a Ki-27 in a single good burst. Simply outrunning any of them is an excellent evasive manoeuvre. Hurricane Mk Is can strictly complete with the Ki-27 Otsu in manoeuvrability, but the Hurricane's heavier armament (four times that of the Ki-27) can also quickly shred a Ki-27. Additionally, outrunning a Hurricane in a Ki-27 is not possible. I-15s, which the Ki-27 historically outperformed, will be the bane of a Ki-27s existence, as their excellent turn ability will force it into energy bleeding manoeuvres or Boom & Zoom style combat. Risky with competition around to abuse either state.

Despite its low battle rating, you can face some challenging foes when flying the Ki-27. Bi-planes will give you a run for your money in terms of manoeuvrability, while some early mono-planes will be faster and more heavily armed than you. Therefore, it is important to judge your foes accordingly.

One of the most challenging opponents is the I-153 Chaika. It is not a mere upgraded I-15bis, but in all performance aspects equal to the Nakajima Ki-27 fighter. Also on the Russian side, the Mig-3 is a significant threat. It is one of the fastest aircraft in its battle rating and has decent armament. In skilled hands, it can be an almost impossible opponent to combat, especially when using Boom & Zoom tactics against you. Your only defence will be to try and outmanoeuvre it or to lure it into a turn fight. The I-16 is also a familiar opponent.

From America, you will face the P-26. They are quite good divers and have a decent roll rate, but will not be able to outmanoeuvre you in a turn fight. The P-36 is more challenging. Faster and well armed, you will have to rely on your turn rate to try and outmanoeuvre them.

Pros and cons

Pros:

• Great manoeuvrability, on par with biplanes
• Good stability in turns
• Good speed, for its tier
• Excellent climb, can reach above 20 m/s

Cons:

• Limited firepower
• Engine overheats rapidly on hot maps
• Engine chokes in negative-G dives
• No armour
• Mostly faces Japan in RB (facing equally / more manoeuvrable planes)

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.
