Description

The Yak-9K is a rank III Soviet fighter with a battle rating of 3.7 (AB), 4.0 (RB), and 4.3 (SB). It was introduced in Update 1.33.

General info

Flight performance

The configuration of the Yak-9K's engine is for excellent low altitude performance and manoeuvrability, though, without necessary turbo or superchargers, the aircraft's performance at high altitude suffers. The Immelmann speed of the Yak-9K is superior to the majority of comparable fighters at the same battle rating making it a capable dogfighter.

Survivability and armour

Examine the survivability of the aircraft. Note how vulnerable the structure is and how secure the pilot is, whether the fuel tanks are armoured, etc. Describe the armour, if there is any, and also mention the vulnerability of other critical aircraft systems.

Armaments

Offensive armament

The Yak-9K is armed with:

• 1 x 45 mm NS-45 cannon, nose-mounted (29 rpg)
• 1 x 12.7 mm Berezin UB machine gun, nose-mounted (200 rpg)

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).

Pros and cons

Pros:

• The 45mm cannon is very good at bomber hunting at ranges up to 1 km
• 45 mm cannon is good for tank busting, thus making the plane a great choice for close air support in ground realistic battles and ground-pounding in aircraft realistic battles
• Good climb rate will allow it to be above its American counterparts the majority of the time
• Great low-altitude performance
• Solid manoeuvrability at low altitudes
• Decently fast

Cons:

• 45 mm cannon is hard to aim
• Un-upgraded 45 mm cannon has a very low accuracy
• Guns jam relatively quickly
• Awful high-altitude performance
• Secondary weapons have limited ammo and do not pack a hard punch

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 If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the vehicle and adding a block "/History" (example: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).

In-game description

The Yak-9 was a Soviet single-engine fighter of the WWII era. It was the first combat aircraft designed by Alexander Yakovlev's construction bureau. The most mass-produced Soviet fighter of the war, it remained in production from October 1942 to December 1948, with a total of 16,769 built.

The Yak-9 was a further modification of the Yak-1 and Yak-7. In its core design, it was a redesign of the Yak-7. With few external differences, Yak-9 was at the same time much more advanced internally. This is not unexpected, as almost two years of design and combat experience of the Yak series went into the Yak-9. Also, at the time aluminium was in much greater supply than it had been two years previously at the start of the war. Amongst other things, the use of metal allowed the plane’s weight to be significantly reduced, meaning that more fuel could be stored and that the aircraft could be equipped with more powerful armament and more specialized equipment.

Media

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