Description

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.

Armaments

Offensive armament

The P-39Q-5 is armed with:

• 1 x 37 mm M4 cannon, nose-mounted (30 rpg)
• 2 x 12.7 mm Browning M2 machine gun, nose-mounted (200 rpg = 400 total)
• 2 x 12.7 mm Browning M2 machine gun, wing-mounted (150 rpg = 300 total)

Suspended armament

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

• Without load
• 6 x 118 mm M8 Bazookas

Usage in the battles

Basic dogfighting skills apply. Use energy tactics and only fire the cannon only under optimum conditions. It is advised to utilize separatekeys for the main weapons. Otherwise, utilise the given machine guns at every opportunity. The centre/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 analyse your opponent's 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 an 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".

Pros and cons

Pros:

• Heavy Armament
• Great Dive Speed Acceleration/Pickup

• Reasonable Turn Time
• High top-end diving speed, can dive up to +800 kph
• Good climb rate

Cons:

• "Jack of all trades, but master of none."
• Different weapon trajectories make aiming difficult
• 37 mm projectiles have extremely low accuracy and muzzle velocity
• 37 mm projectiles are incapable of defeating tank armour, 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.
