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, though not as bad as VK-105 powered Yaks. It also has good manoeuvrability that gets better at higher speeds (above 400 km/h), but you will still be outmanoeuvred by Zeroes and Spitfires. Keep in mind that the ailerons will start to compress above 500 km/h

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 meters 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.

Engaging fighters & bombers

Most enemy fighters will be between 3000 and 4500 meters, with bombers being around 4000 to 5600 meters. It's important to use your height advantage, drop down from your height and and get behind the enemy. Once behind the fighter or bomber, do not engage it until you are close enough to see their tails in your crosshairs. Aim forward and fire only a single shot or a short bust, if armed with the 45 mm cannon (which is no longer than two seconds). Using the 37 mm N-37 cannon or the 27 mm NS-27 cannon, use a bust which is around two and half seconds.

If you miss and they turn, pending how sharp the turn is follow them. If it's a very sharp turn do not turn with them, instead open the throttle and climb back up to gain a height advantage. Then either try it again or find a new bandit to knock out.

Ground & Naval Battles

In ground and naval battles, the Yak-9K is able to destroy armoured targets, with ease. It does not have any secondary armaments such as bombs or rockets. However, it's 45 mm cannon is able to destroy heavy tanks. To do this, aim for the roof and dive straight down upon them like an angle which is fighting a demon.

In ship combat, the 45 mm cannon is able to penetrate the decks of many heavily armoured ships, but you must aim for roof or sides of the ships. Handling smaller ships such as Patrol boats, do not fly in a straight line instead zip up and down, left to right then suddenly turn and shoot them. A single well placed shot will destroy their ammo racks and set the ship to visit davy jones locker!

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
• Very quick engine spool up and spool down time

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
• Ailerons compress above 500 kph

History

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.
