Description

GarageImage Whirlwind P.9.jpg


The Whirlwind P.9 is a gift rank III British twin-engine fighter with a battle rating of 4.3 (AB/SB) and 3.7 (RB). This aircraft was introduced in Update 1.77 "Advancing Storm" during the 2018 World War Two Chronicles. It was later re-released during Update 1.91 "Night Vision" as a reward for Operation "Shipyard". Whirlwind P.9, an experimental pre-production vehicle, is the direct ancestor of the British Whirlwind Mk I heavy fighter. Development of the aircraft began in 1937 and the aircraft in this series had plenty of time to fight against German aircraft and ships during the Battle of Britain.

General info

Flight performance

The vehicle is agile and speedy on level flight. The maneuverability is surprising, and even better with the use of flaps, making it possible to dogfight with most of the twin-engine fighters and, with skill and situational advantages, few single-engine planes as well. Just be wary of not draining all your speed while dogfighting enemies.

If played conservatively, this plane can be a tenacious opponent, especially when having an altitude advantage as this allows the Whirlwind P.9 to dive, fire, and then escape from enemies all with the same energy. This way a pilot can exploit the Whirlwind P.9's great speed to minimize the enemy's chance of getting a successful hit.

Survivability and armour

Packed with wide 2 layers of armour (both of 9mm) in front of the pilot, covering the 20 mm cannons and the engine. The bulletproof glass (60mm) will also be helpful in head-ons or when hunting turret defended planes.

The Whirlwind P.9 has a vulnerable tail as the elevator and ailerons generally will be blown off if the enemy gets to blaze you from behind or wins in a head-on. Hence you should avoid be caught off guard as it will much likely end your flight capacities.

Armaments

Offensive armament

Main article: Hispano Mk.I (20 mm)

The Whirlwind P.9 is armed with:

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

The four cannons make the Whirlwind P.9 well armed for head-on engagements or Boom and Zoom tactics, as the four nose-mounted cannons will shred through everything, specially with the Ground Targets belt due to its AP ammunition.

Although gun convergence its a personal choice, it's suggested to set the gun convergence of the nose mounted cannons to 600m as the 4 cannons are lined horizontally. This allows to score great shots at the moment of diving to an enemy without getting to close or too far away. Just enough to aline with the targets flight trajectory and release a shot burst. If engaged with them in dogfight just keep in mind this distance.

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 that the Whirlwind P.9 has more than double the ammunition count.

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.

At this battle-rating you will see many BV 238s and Me 264s. Heading on these bombers will usually guarantee you a kill, but you still need to be careful of the powerful defensive armament of them.

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
  • Deadly with the Ground Targets belt

Cons:

  • Ammo can deplete pretty quickly (though still double that of the 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).
