Usage in battles

Describe the tactics of playing in an aircraft, the features of using vehicles in a team and advice on tactics. Refrain from creating a "guide" - do not impose a single point of view, but instead, give the reader food for thought. Examine the most dangerous enemies and give recommendations on fighting them. If necessary, note the specifics of the game in different modes (AB, RB, SB).

Pros and cons


  • Devastating nose-mounted 20mm Hispano armament.
  • Great for head-ons.
  • Good turn rate when upgraded for a twin engined fighter.


  • Poor climb rate.
  • Under-powered engines.
  • Drum-fed Hispano Mk1s. Only 60 rounds per gun. You must make every round count.
  • Inaccurate Hispano Mk1 cannons. Precise aiming is hard.
  • Poor roll rate
  • Quite slow level flight speed
  • Unfavorable matchmaking puts you up against some very challenging opponents


The Westland Whirlwind was designed after a specification was issued by the British Air Ministry. The specification called for a cannon-armed day and night fighter. The Air Ministry wanted a top speed of at least 530 km/h at an altitude of 4,600m. Out of five designs offered by the companies. The Air Ministry decided to go with Westland's design for several important reasons. The cannon was mounted on the nose so that the recoil does not affect the accuracy of the gun. There were also no convergence problem as compared to other single-engine fighters with wing mounted guns. The requirements also led to the world's first bubble canopies on a plane. However the decision to arm the Spitfire with cannon and the development of other twin engine fighters such as the Bristol Beaufighter has led Fighter Command to use the Whirlwind less and less as the war progressed. The first batch of Rolls-Royce Peregrine engines were also delayed. It was also found that the engine was severely under-powered and the drum magazines used to feed the cannons were small in capacity. All of this has resulted in the Whirlwind's cancellation and resulted in the plane only equipping two RAF squadrons.


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