Description
The ◔Yak-9P is a rank IV Italian fighter with a battle rating of 5.0 (AB/RB) and 5.3 (SB). It was introduced in Update "Alpha Strike".
The Yak-9P was a powerful variant of the Yak-9, optimized for combating bombers and heavily armored targets with its 37-mm cannon. While it was less maneuverable compared to other fighters, its enhanced firepower made it a valuable addition to the Soviet Air Force during World War II.
General info
Flight performance
The Yak-9P (Italy)'s performance can be compared to the Yak-9U. The M-107A engine is the same model as as the 9U's, but it generates slightly less horsepower on the 9P for reliability reasons. The weight of the aircraft has also increased in large part due to the expanded fuel capacity. The minimum fuel load of 23 minutes is larger than the 9U's 16 minutes, for example. These factors negatively affect the 9P's climb rate and power-to-weight ratio, but these factors still remain quite decent. As is the case for members of the Yak fighter family, the Yak-9P has crisp controls, good manoeuvring energy retention, and a good turn rate at medium speeds, making it a good dogfighter. Control stiffening in the roll rate starts early at around 500 km/h IAS. The control surfaces start to compress significantly at 650-700 km/h. The handling at extremely low speeds is not exceptional, in these cases consider using the takeoff flaps.
The Yak-9P's metal airframe gives it a higher rip speed and slightly less control compression than the Yak-9U, a welcome improvement. High speed dogfighting and prolonged dives should still be avoided since the Yak-9P is still not designed for these tactics compared to Mustangs or Thunderbolts, but it should be able to give chase to other fleeing aircraft.
The M-107A engine is among the most powerful of the Soviet inline engines, contributing to the good energy fighting capabilities of the late Yaks, but has a number of quirks. It loves to overheat on WEP and even opening the radiators all the way does not eliminate the problem. If using Manual Engine Controls, try to keep the radiators fairly or entirely open under normal circumstances when maximum speed is not critical. Bumping up the propeller pitch to high percentages will help bring out as much thrust from the engine as possible, which helps to compensate for the Yak-9P's weight at the cost of overheating the engine slightly more quickly. To cool the engine quickly when out of combat, open the radiators, drop the propeller pitch, and dial back the throttle.
Engine performance and flight characteristics are good up to 4 km of altitude and decent at 5 km, but going to 6 km and above is not recommended. Medium to low altitude dogfights are the Yak-9P's forte.

Survivability and armour
- 8 mm Steel - Plate behind pilot's seat
- 64 mm Bulletproof glass - Pilot's head rest
- 64 mm Bulletproof glass - Front canopy window
The Yak-9P's all metal construction contributes to somewhat more survivability than the previous Yaks, but it is still not an exceptionally durable plane. The pilot has enough protection from the rear to survive stray machine gun shots. The frontal bulletproof glass is nice and thick and can resist machine guns and weaker cannons. The main issues in terms of durability are the numerous fuel tanks in the wing roots and the vulnerable liquid-cooled engine in the front. Use the Yak-9P's manoeuvrability to dodge fire as much as possible, the temperamental M-107A engine and large fuel capacity make engine damage and fires hard to deal with.

Four upgrades are of importance: Offensive 20 mm, Compressor, Engine and Engine Injection. During this grind the second weapons profile (NS-23) can be easily be obtained without wasting time or XP.
Note that equipping the "NS-23 cannon" or "N-37 cannon" modifications by themselves will also decrease the accuracy of the B-20S cannons to stock values. The "New 23 mm cannons" and "New 37 mm cannons" modifications should be equipped to restore their accuracy and reliability.
Armaments
Offensive armament
The Yak-9P (Italy) is armed with:
- A choice between three different cannons, the 20 mm B-20M, 23 mm NS-23, or the 37 mm N-37:
- 1 x 20 mm B-20M cannon, nose-mounted (115 rpg)
- 1 x 23 mm NS-23 cannon, nose-mounted (75 rpg)
- 1 x 37 mm N-37 cannon, nose-mounted (28 rpg)
- 2 x 20 mm B-20S cannon, nose-mounted (120 rpg = 240 total)
The Yak-9P is the first Soviet single-engine fighter with a customizable armament in the form of the centreline cannon firing through the propeller hub. All cannon loadouts have two synchronized 20 mm B-20S cannons in the nose; these are effectively ShVAKs with a slightly higher rate of fire and retain the same belts. The Default belt is quite good as it has AP-I rounds for starting fires and FI-T rounds for ease of aiming and some mild explosive damage. Those confident in their aim can use Armoured Targets for higher AP-I content. Avoid belts containing HE-F rounds since they have less explosive content than the FI-T rounds and deal very little damage.
The default option for the centreline cannon is a B-20M cannon with 115 rounds, and the overall setup of three B-20 cannons is the same as the Yak-3P. This loadout is not much to write home about from a damage perspective; compared to the Yak-9U's single ShVAK and twin Berezin UB combination, it has higher kinetic damage but less efficacy at starting fires. On the bright side, this homogeneous armament is very accurate and easy to use. Note that the centreline cannon will run out of ammunition about 1 second before the synchronized cannons.
The 23 mm NS-23 cannon with 75 rounds packs a greater punch than the B-20M. The FI-T rounds contain significantly more explosive filler and the AP-I rounds have greater kinetic damage, capable of knocking out inline engines in a single shot. The main downsides are the slightly worse ballistics (710 m/s vs 800 m/s for B-20s) and more limited firing time (7.5 seconds). The Default belt again has an even mix of AP-I and FI-T rounds for a good balance of kinetic damage and explosive damage.
The 37 mm N-37 cannon with 28 rounds may remind pilots of the Yak-9T's deadly NS-37 cannon. The N-37 is lighter, more accurate, and fires more quickly but suffers from a lower muzzle velocity (610 m/s) and is not very effective against ground vehicles. Its HE rounds actually behave more like APHE rounds, exploding shortly after penetrating a target instead of on impact. This means that the rounds could overpenetrate an aircraft on occasion and explode outside for less damage; follow-up shots should be expected. When it does work right, the N-37 can dispatch large planes quickly. It has the least firing time (4.2 seconds) of all the Yak-9P's cannons and trigger discipline is important.
During the Yak-9P's stock grind, players who want to focus on flight performance upgrades first should consider sticking with the triple B-20 setup, which can be easily brought to a usable standard by going straight for the New 20 mm Cannons upgrade. It is a convenient and reliable option that is sufficient against fighters and other smaller aircraft. The N-37 is a good option for bomber hunting but may be tricky to use against small targets due to the muzzle velocity and quirks of the HE rounds. The NS-23 is a good compromise of firepower and ease of use. All loadouts suffer from limited ammunition, so an average pilot may be able to score 1-2 kills before needing to rearm.
Usage in battles
Though the Yak-9P is similar to the Yak-9U in terms of design, handling, and performance, its places more emphasis on armament than performance. The Yak-9U could match or exceed most of its opponents in climb and speed and easily engage in energy fights. The Yak-9P faces tougher opposition and it is difficult to argue that the performance has improved, so it is important to pick your battles carefully and make good use of the powerful guns to destroy opponents quickly.
In Air AB, it's best to stick to moderately low altitude (below 5,000 m), as is typical with Soviet piston-engine aircraft. Though the VK-107 engine in the Yak-9P is significantly more powerful than the VK-105 engine used in most previous inline-engine Soviet fighters, its performance keeps getting worse as the plane goes higher, though the Yak-9P's maximum effective altitude is slightly higher than VK-105 Yaks. The Yak-9P's significantly better armament compared to the Yak-9U allows it to take down even heavily armoured foes, and with the 23 or 37 mm cannon upgrades, the Yak-9P can be a devastating interceptor against bombers that haven't climbed. It can be played somewhat like a heavy version of the Yak-3P - faster and with better armament options, but not as manoeuvrable overall.
In Air RB, the Yak-9P is best used cautiously by new pilots. The climb rate is not exceptional for its battle rating, so it may be better to hang back slightly, reach medium altitudes, and wait for teammates to start combat. If you can successfully jump on an enemy's tail at medium speeds, the Yak's balanced performance makes it hard for them to pull a reversal. Turning engagements often end in the Yak's favor since it has a good turn rate and does not lose much speed in horizontal manoeuvres, though this is not advised against very manoeuvrable aircraft like Spitfires and Zeros. Vertical manoeuvres and loops can be used to energy-trap heavier opponents but keep in mind that the Yak-9P's handling at stall speeds is not impressive. Try to avoid combat at high speeds; though the Yak-9P is more structurally durable than other Yaks and Lavochkins, it still rips earlier than many other fighters and the control stiffening makes it easy for enemies to dodge fire or pull a reversal.
Keep an eye on the engine temperature. MEC helps greatly for managing the radiators and propeller pitch as discussed earlier. Heated combat routinely results in orange and sometimes red engine temperatures. Do not let the engine cook itself and give it a break when out of combat. If things get dire or the engine has been worn down to the point where the overheat threshold is uncomfortably low, consider returning to base, as rearming and repairing will also reset the engine.
