Description

The Yak-9UT is a rank IV Russian fighter with a battle rating of 6.0 (AB), 5.7 (RB), and 6.3 (SB). It was introduced in Update 1.37.

General info

Flight Performance

The Yak-9UT has an extremely high acceleration rate which is enhanced compared to earlier Yaks due to using the new Klimov M-107 engine. Unfortunately, like all Yaks, it has a poor engine performance at high altitude. Thankfully it is not as bad as VK-105 powered Yaks in that respect. It also has good manoeuvrability that gets better at higher speeds (above 400 kph) but you will still be outmanoeuvred by Zeroes and Spitfires.

The Yak-9UT doesn't have any the ability to carry bombs, however, it does have access to other gun configuration options many other aircraft do not have. By default, you have twin B-20S 20 mm cannons mounted on the top of the nose cowling and a single 23 mm cannon mounted in the propeller shaft, you have also access to the twin B-20S and an N-37 37 mm cannon with higher damage but less ammo and fire rate. Finally, the last gun setting, a single B-20S and an N-45 45 mm cannon with only HEFI-T rounds (High Explosive Fragmentation Incendiary Tracers) that has a benefit of higher bullet speed and a few more ammunition rounds over the 37 mm variant.

Survivability and armour

The aircraft features two 64 mm bulletproof glass plates located the front and the rear of the cockpit and an 8mm steel plate located just behind the pilot's seat.

Armaments

Offensive armament

The Yak-9UT is armed with:

• A choice between three presets:
  • 1 x 23 mm NS-23 cannon, nose-mounted (80 rpg) + 2 x 20 mm B-20S cannons, nose-mounted (120 rpg = 240 total)
  • 1 x 37 mm N-37 cannon, nose-mounted (28 rpg) + 2 x 20 mm B-20S cannons, nose-mounted (120 rpg = 240 total)
  • 1 x 45 mm NS-45 cannon, nose-mounted (29 rpg) + 1 x 20 mm B-20S cannon, nose-mounted (170 rpg)

Usage in battles

Since this aircraft has a very high low-to-middle altitude acceleration, you should use this plane primarily as a dogfighter at those altitudes. It is also important to note that this plane like all Yaks and like most other Soviet-built fighters, low high-altitude performance, however, even at higher altitudes, this fighter can be used as a Boom & Zoom aircraft, provided you pay attention to your speed. Turn-fighting and dogfighting above 4500 m are discouraged as at this altitude, many other aircraft will have superior turn capabilities and engine performance compared to the Yak-9UT, leaving it to struggle for any flight advantage.

While performance tends to suffer at higher altitudes, when kept closer to the ground, the Yak's performance starts to shine. This is especially true with its energy retention, such as performing a ~270-degree turn with minimal kph lost (~30 kph) and the ability to regain this speed extremely fast.

Pros and cons

Pros:

• Good low-speed manoeuvrability that gets even better at higher speeds (above 400 kph)
• Nose-mounted cannon is effective against all types of aerial targets
• You can choose between various cannons without changing the whole aircraft
• As all Yaks, it has a stunning low-to-mid altitude acceleration
• Very good energy retention at low altitudes
• This plane can reach more than 550 kph IAS at low altitudes and 500 kph IAS at 4000 m

Cons:

• Low diving speed
• Low cannon ammunition
• Engine easily overheats
• 20 mm HEF-I and FI-T from B-20S cannon is not effective against large aircraft
• Engine power weakens at high altitude, which means less acceleration

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.
