In developing this aircraft, the Bell designers came up against two global problems. The first was that the P-39 was intended for export, and there was no way around this. The impossibility of fitting a turbo compressor to the low-altitude Allison engine (for fully explicable reasons) was one reason why the aircraft was never able to achieve a worthy place in the US air forces. The nature of air combat, both in Europe and the Far East, prevented the P-39 from making use of its advantages, while it was not possible to rectify its main drawback - its poor high-speed performance - because of the ban on exporting turbo compressors outside the USA.

Usage in battles

Describe the tactics of playing in the aircraft, the features of using aircraft 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

Pros:

  • Powerful engine, quick cooling
  • Well-armoured
  • Good firepower
  • Cockpit has good visibility

Cons:

  • Turn rate is subpar
  • High-altitude performance is bad (>3,000 m)
  • Many fighters can outperform it at its BR
  • The engine is centrally mounted, taking engine damage while being chased is common
  • 37 mm M4 cannon isn't very accurate & shell velocity isn't very high
  • 37 mm M4 cannon's belt contains a mix of AP and HEFI rounds, halving its effectivrness in either air combat or ground attack
  • No suspended ordnance options

History


Archive of the in-game description

In developing this aircraft, the Bell designers came up against two global problems. The first was that the P-39 was intended for export, and there was no way around this. The impossibility of fitting a turbo compressor to the low-altitude Allison engine (for fully explicable reasons) was one reason why the aircraft was never able to achieve a worthy place in the US air forces. The nature of air combat, both in Europe and the Far East, prevented the P-39 from making use of its advantages, while it was not possible to rectify its main drawback - its poor high-speed performance - because of the ban on exporting turbo compressors outside the USA.

The second global problem was connected to a technical failure in the production of the 20 mm Hispano-Suiza AN-M1/M2C cannon by the Bendix company. This was the first problem the Bell specialists tried to tackle. The Bell specialists initially tried to solve this problem themselves. The virtually unusable 20 mm cannon was replaced by the old, heavy but more reliable Colt-Browning M4. The cannon had a lot of faults, mainly its low rate of fire and extremely inadequate stock of ammunition - only 30 shells. On the other hand, in spite of its weight, it could easily be fitted in the front part of the Cobra's fuselage; furthermore, it has one incomparable advantage over the Bendix product - it actually fired.

It must be noted that the M1 cannon was not always fitted onto the first series of the P-39, you could find the M4 here and there. Only the Model 26 (P-39G) carried the M4 as standard equipment. However, it did not go into production, but became the founder of a whole number of virtually identical series from P-39K to P-39Q. The main units were borrowed from the quite promising P-39D-2 series.

The P39K differed from the earlier models in its engine, the Allison V-1710-63, which was successfully tested in that same D-2. It was fitted with an afterburner system. It developed a nominal power of 1,352 hp and 1,550 hp in WEP (War Emergency Power) mode. The K series was the only one fitted with such an engine along with a three-bladed Aeroprop propeller. It was a full 360 kg heavier than the D-2, although externally, apart from the propeller, there was no visible difference. In fact, the extra weight was due to additional armour plating, which was used beginning with the K and on all subsequent series.

Altogether, by August 1941, 210 examples of the series K-1-BE, K-2-BE and K-5-BE, which were virtually identical, were built. Forty of them were sent to the USSR.


Notable pilots

  • Alexander Pokryshkin flew the ▂P-39K-1 Airacobra during the battle of Kuban starting his 47 kill-streak with the P-39 series lend-lease aircraft.
