General info

P-39N-0 Airacobra in the garage.

The P-39N-0 Airacobra is a Rank II American fighter with a battle rating of 3.3 (AB) and 3.0 (RB/SB). It was in the game since the start of the Open Beta Test prior to Update 1.29.

The main purpose, usage and tactics recommendations

General play style

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 37mm M4's dropping trajectory and slow rate of fire make it useless in head-on passes. Therefore, prioritise low altitude objectives, like escorting attackers & low alt bombers, or prey on the ones of the enemy.

Vehicle characteristics

Tactics

Basic dogfighting skills apply. Use energy tactics and only fire the cannon only under optimum conditions. A separate key for the main gun is advised. Otherwise utilise the given machine guns at every opportunity. Especially those 7,92 light machine guns in the wings, with 750 rounds per gun you wont run dry that fast. The center/cowling mounted .50cals 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-39's sleek and rather aerodynamic form, BnZ is the preferred form of combat. However TnB is an option as well. Again, the P-39 provides all the options a pilot wants "Jack of all traits, master of none".

Pros and cons

Pros:

  • Absurd climb rate when upgraded (nearly 25 m/s)
  • Heavy Armament
  • Great Dive Speed Acceleration/Pickup
  • Reasonable Turn Time
  • Great amount of 7.62 (.306) ammo (750 rpg)

Cons:

  • "Jack of all trades, but master of none"
  • Three different weapon trajectories make aiming difficult, although this is less of a problem if you are used to the P-400
  • Long countdown for the 37 mm in both overheating and reload
  • Easy to stall with full controls.
  • Cannot fire the 2 MGs separately.
  • Ammunition count for the M2s is low, limiting their usage time.
