Description

GarageImage Spitfire F Mk IX.jpg


The Spitfire F Mk IX is a rank III British fighter with a battle rating of 4.3 (AB/RB) and 4.7 (SB) This fighter was introduced in Update 1.35.

Because the muzzle velocity of both the Hispanos (muzzle velocity: 870 m/s) and the MGs (muzzle velocity: 854 m/s) is practically the same you could put tracers on the MGs and air belt on the Hispanos. This is a great way for players to get a feel of where to aim in RB and it's easier to hit your shots maximizing your efficiency and potentially saving ammo. A downside to this is that the element of surprise is short lived as your enemy will see the tracers flying past him and he will quickly react. Another thing is that short bursts are required with the cannons especially without the cannon upgrades as they overheat (and thus jam) very quickly.

Pros and cons

Pros:

  • Great manoeuvrability
  • Good roll rate
  • Good low-level performance
  • Larger ammo supply of 120 RPG for the 20 mm cannons, compared to some predecessors with 60 RPG
  • Machine gun ammo pool of 350 RPG makes for good, prolonged backup weapons
  • Faster than previous Spitfire versions due to a newer engine
  • Performing quick negative G manoeuvres will not shut off the engine (RB/SB)
  • You can actually use tracers belts for machine guns, which means this aircraft can help new RB player with shooting

Cons:

  • Ammunition pool for 20 mm still relatively small, must be conservative when shooting
  • Cannons overheat and jam quickly, especially when in stock configuration
  • When 20 mm runs out or jams, the plane is left with only four rather underwhelming 7.7 mm machine guns
  • Poor high altitude performance
  • Poor acceleration
  • Roll rate starts stiffening at ~400 kph
  • Liquid-cooled engines mean one hit to the cooling system can force a return to the airfield for repairs (RB/SB)
  • Very difficult to attack bombers, as the engine is very susceptible to damage from enemy gunners

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 If the historical reference turns out to be too big, take it to a separate article, taking a link to an article about the vehicle and adding a block "/ historical reference" (example: https://wiki.warthunder.com/Name-vehicles/historical reference) and add a link to it here using the main template. Be sure to include links to sources at the end of the article.

In-game description

"The Supermarine Spitfire was a British single-engine, all-metal, low-wing monoplane fighter. While the Mk VII and Mk VIII variants was being designed, a Spitfire Mk III was tested in September 1941 with the new Rolls Royce 60 in the hopes of developing an interim fighter to use as a stop gap measure. The new Spitfire performed exceptionally well, and was rushed into production as the Mk IX. The Air Fighting Development Unit described the Mk IX as ‘outstandingly better than the Mk V especially at heights above 20,000 feet’ and even though it was not fitted with the modified control surfaces under development for the Mk VII and Mk VIII, the Mk IX was more than capable of meeting the Focke-Wulf FW190 on favourable terms. The Mk IX was fitted with the Type C ‘universal’ wing and originally carried the tried and tested combination of two 20mm cannon and four 0.303 inch machine guns, but in later versions the four 0.303 machine guns were replaced with two .50 calibre guns.

A total of 5,665 Mk IX were produced and 262 more Mk Vs were converted to Mk IX. Intended as a transitional stop-gap measure for the Mk VII and Mk VIII, the variant remained in production until the end of the war, ultimately becoming the most mass-produced Spitfire version. This mark was also used as a fighter-bomber and as a reconnaissance aircraft. Further modifications were incorporated into the Mk IX throughout its service life, such as a gyroscopic gunsight, bubble canopy and modified engine intercooler. Widely considered to be the most capable fighter in the world at the time of its introduction, it would take the introduction of the Rolls Royce Griffon engine to push the Spitfire into its next stage of evolution.
