It was later rereleased during Update 1.91 "Night Vision" as a reward for Operation "Shipyard".

General info

Flight performance

Describe how the aircraft behaves in the air. Speed, manoeuvrability, acceleration and allowable loads - these are the most important characteristics of the vehicle.

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 Whirlwind P.9 is armed with:

• 4 x 20 mm Hispano Mk.I cannons, nose-mounted (121 rpg = 484 total)

Usage in battles

The Whirlwind P.9 should be used similarly to other heavy fighters. The flight characteristics are very similar to the Whirlwind Mk I with the main difference being significantly more ammo.

The P.9 is very effective in a boom and zoom role due to its good climb rate, and powerful armament. However, the relatively low wing break speed in RB does limit you in this role. The Whirlwind P.9 has a good turn rate for a heavy fighter, but will be easily out turned by single-engined fighters. The use of combat flaps will help to balance out this disadvantage. Care must be taken when using the combat flaps, however, as the are prone to snapping off at a relatively low speed.

Pros and cons

Pros:

• Devastating armament in 4 x nose-mounted 20 mm Hispano cannons
• Closely packed nose-mounted guns are great for head-on attacks
• Good turn rate for a twin-engined fighter
• Decent manoeuvrability for a heavy fighter
• Decent roll rate for a heavy fighter

Cons:

• Ammo can deplete pretty quickly(still double that of whirlwind Mk I)
• Slower than average dive speed
• Experiences severe control stiffening at speeds above 500 km/h

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 If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the vehicle and adding a block "/History" (example: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

Media

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