Description

The Yak-9P is a rank IV Soviet fighter with a battle rating of 5.0 (AB/RB) and 5.3 (SB). It was introduced in Update 1.31.

General info

Flight performance

The Yak-9P's performance is similar to the Yak-3P's, albeit slightly faster with a worse turn rate. The aircraft engine performs effectively up to ~4 km altitude before a noticeable loss of horsepower. The control surfaces start to compress at 650-700 km/h; however the aircraft will only rip at ~800 km/h, an improvement over the Yak-3.

Armaments

Offensive armament

The Yak-9P 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)

Usage in battles

When stock, the Yak-9P will be pretty similar to the Yak-3P. Three 20 mm cannons which are good taking down fighters and heavy fighters, but its still quite hard to kill big targets such like B-17. When unlocking the 23 mm cannon, the damage is higher, but it carries significantly less ammo than the 20 mm. However, when equipping the 37 mm cannon, the effectiveness of the fighter increases significantly, having weaponry close to MiG-9 or MiG-15. The 37 mm cannon has an excellent rate of fire, won't jam easily, has great accuracy and carries a good amount of ammo. A single hit can kill a fighter or heavily damage it, and big bombers like B-17s will be killed with one or two hits on a wing.

The Yak-9P is best when used in turn fights and boom and zoom attacks, but speeds of 700 km/h or higher can end on low control response (making it hard to recover) and wings breaking. It can climbs best at 20 degrees and 10-15 above 4000 m. It has great engine performance and will sightly overheat after long WEP use, but will cool down quickly when reducing to just 85-90% throttle.

One rather unique feature of the Yak-9P is the modification possibility for ones own liking. The default setup is has got a centerline B-20M. It is virtually the same as the B-20S and utilizes the same belts OR one can switch out the 20 mm for a nasty 23 mm. The suggested modification by many pilots. The NS-23 has similar ballistics to the installed 20 mm cannons but packs more punch. Fortunately the rate of fire is lower for the NS-23 and both arms will run out of ammunition at roughly the same time. For the fellow pilots who still dreams of the Yak-9T: The 37 mm "howitzer", it is a deceptive package though! The N-37 is not the NS-37 from the Yak-9T and lacks any decent anti-armour shells, losing 20 mm of penetration. Two shells were also lost from the 9T, but on the bright side it still delivers painful HE warheads to the enemy.

Pros and cons

Pros:

• Very fast when flying below 4000m
• Powerful armament
• Good energy retention, vertical & horizontal
• Decent rate of climb
• Decent rate of turn
• Nose mounted cannons are very accurate
• Good acceleration...

Cons:

• ...But since the plane is all made of metal and is heavier, it has less acceleration than other M-107 Yaks
• Can't reach speeds as high as other aircraft during dives, such as Fw-190, P-51 and F4U variants
• Not very nimble at speeds lower than 300 km/h
• Control stiffening when flying above 500 kph, the roll rate is significantly decreased
• Engine horse-power significantly lower when flying above 4000m

In-game description

"This aircraft was the last and the most advanced version of the Yak-9 fighter, which became the pinnacle of development among A. S. Yakovlev's piston-engined fighters. The Yak-9P (Product P) that appeared in 1946 was a modification of the Yak-9U fighter of composite construction. Unlike its predecessor, it had all-metal wings with elliptical tips. By this time, the manufacture of high-strength aluminum alloys was established in the Soviet Union, simplifying aircraft operation and increasing aircraft service life.

The first production aircraft were released with all-metal wings and plywood fuselage coverings, but from 1947 on these fighters were all-metal. The plywood covering over the rear fuselage was replaced with riveted duralumin.

The Yak-9P was fitted with various state-of-the-art instruments and radio communication equipment, including a radio compass and an identification friend or foe transponder, which was upgraded and improved as the aircraft's production continued. Fuel quantity in the wing-mounted tanks was significantly increased. In late 1947, the airplane's builders began installing reversible pitch propellers on some Yak-9Ps, cutting the plane's rolling distance in half and eliminating the risk of the aircraft nosing over in case it decelerated abruptly.

The fighter's armament consisted only of cannons: two synchronized 20 mm Berezin B-20 cannons and a uniform central cannon mount comprising a 37 mm Nudelman-Suranov NS-37 engine cannon with 28 rounds. The NS-37 could be replaced with a 20 mm B-20 cannon (115 rounds), a 23 mm NS-23 cannon (75 rounds), or a 45 mm N-45 cannon (26 rounds).

The Yak-9P's production continued until December 1948. By that time, 29 aircraft had been built with metal wings and a plywood-covered fuselage, and 772 planes with an all-metal construction. The Yak-9Ps were withdrawn from service with the USSR in the early 1950s.

The Yak-9P fighter was in service not only with the Soviet Union, but also with China, North Korea, Hungary, Albania, Poland, and Yugoslavia. North Korean Yaks were used during the initial stage of the Korean War, fighting against both piston-engined and turbojet enemy fighters."
