The '''P-39Q-5 ''Airacobra''''' is a Rank II American fighter with a battle rating of 3.7 (AB) and 3.3 (RB/SB). It was in the game since the start of the Open Beta Test prior to Update 1.29.

The primary purpose of a P-39 is that of a low-level interceptor against low energy aircraft. It lacks the high-altitude performance needed to engage strategic-bombers. The 37 mm M4's dropping trajectory and slow rate of fire make it useless in head-on passes. Therefore, prioritize low altitude objectives, like escorting attackers & low alt bombers, or prey on the ones of the enemy.

Basic dog fighting skills apply. Use energy tactics and only fire the cannon only under optimum conditions. A separate key for the main gun is advised.

Otherwise utilize the given machine guns at every opportunity. The center/cowling mounted .50 cals provide great long range accuracy & harassment.

"Jack of all trades, master of none" is the credo of the Airacobra. Thus the basic tactic is to analyze your opponents weakness and then exploit it.

The P-39 will always find an area, it is exceeding the foe. Or at least, is on par to let the skill decide.

Given the P-39s sleek and rather aerodynamic form, Boom & Zoom is the preferred form of combat. However Turn & Burn is an option as well.

Again, the P-39 provides all the options a pilot would want, a "Jack of all trades, master of none".

Description

GarageImage P-39Q-5.jpg


The P-39Q-5 Airacobra is a Rank II American fighter with a battle rating of 3.7 (AB) and 3.3 (RB/SB). It was in the game since the start of the Open Beta Test prior to Update 1.29.

The primary purpose of a P-39 is that of a low-level interceptor against low energy aircraft. It lacks the high-altitude performance needed to engage strategic-bombers. The 37 mm M4's dropping trajectory and slow rate of fire make it useless in head-on passes. Therefore, prioritize low altitude objectives, like escorting attackers & low alt bombers, or prey on the ones of the enemy.

Suspended armament

Main article: Rockets

The P-39Q-5 can outfit the following ordinance options:

  • Without load
  • 6 x 118 mm M8 Bazookas

Usage in the battles

Basic dog fighting skills apply. Use energy tactics and only fire the cannon only under optimum conditions. A separate key for the main gun is advised. Otherwise utilize the given machine guns at every opportunity. The center/cowling mounted .50 cals provide great long range accuracy & harassment.

  • Heavy Armament
  • Great Dive Speed Acceleration/Pickup
  • Good secondary armament of four HMG
  • Reasonable Turn Time
  • High top-end diving speed, can dive up to +800 kph
  • Good climb rate

  • 37 mm projectiles have extremely low accuracy and muzzle velocity
  • 37 mm projectiles are incapable of defeating tank armor, even at optimal angles with APT rounds
  • Long countdown for the 37 mm in both overheating and reload
  • Easy to stall with full controls
  • Low ammo count for the machine guns

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.

Media

An excellent addition to the article will be video guides, as well as screenshots from the game and photos.

Read also

Links to the articles on the War Thunder Wiki that you think will be useful for the reader, for example,

  • reference to the series of the aircraft;
  • links to approximate analogues of other nations and research trees.

Sources

Paste links to sources and external resources, such as:

  • topic on the official game forum;
  • page on aircraft encyclopedia;
  • other literature.
