Question....

I am very familiar with the role of the P39D and P-400, but did the P-39N serve in the PTO?

If so, where, when and did the USAAF add a bunch of armor and stuff or is it the one that we currently enjoy in FB?

How about other versions...Q for example?

The prototype of the P-39 "Airacobra" fighter - XP - 39 (Model 12) was developed by the American Bell Aircraft Corporation in 1938. The fighter was built in such a way as to carry weapons of the largest caliber ever installed on a one-engine aircraft of the time. It was armed with a 37mm T9 cannon - developed by the American Armament Corporation - which fired through the propeller hub, and two synchronized 12.7mm caliber Browning machine-guns installed in the forepart of the fuselage. The engine had to be installed inside the fuselage behind the cockpit to place a gun of this caliber. The air propeller was started with the help of a shaft placed under the cockpit floor.

However, powerful armament availability was not the only concern for the designers working on the new fighter. Along with its fire power, they had to provide for aircraft operation at any time of the day and on ill-prepared runways. With the engine placed behind the cockpit, Bell designed a tricycle landing gear with a steerable nose wheel enabling taxing at high speed, take-off and landing on unprepared surfaces without the risk of the aircraft tipping over. Except for the hydraulic brakes, all XP-39 systems (later P-39) came with an electric drive. The cockpit was very practical and comfortable.

After the trials, the aircraft was completed and launched into large-scale production bearing the name P-39. In the course of production, a great number of modifications were made concerning the armament, engine, air propeller type, fuel reserve and other features. It is worth pointing out that "Airacobra" became increasingly perfected with each new modification.

The N version of the "Airacobra" (P-39N, P-39N-1 and P-39N-5 series) differed from the previous modifications in terms of improved flight performance due to a reduced fuel reserve (325 l) and weaker armor protection. This version of the P-39 saw the introduction of the new Allison V-1710-85 engine (power 1,200 HP) and Aero Prop propeller. The aircraft's armament consisted of a 37mm T9 cannon, two 12.7mm machine guns in the nose and four wing-mounted 7.62mm Browning machine guns. Overall, 2,095 aircraft of this variation were produced.

The Airacobra was shipped to the USSR under the lend-lease program. Altogether, the Soviet Union received approximately 4,750 P-39 aircraft of D, N and Q variations.

Good flight performance at low altitudes allowed the Airacobra to be used effectively for escorting Il-2 attack planes and protecting them from enemy fighters, bomber intercepts as well as ground attack. Contrary to popular belief, Soviet Union never used P-39s in ground attack role.

Advantages: One of the best mass-produced front-line fighters of the Second World war with excellent performance characteristics. Excellent aerodynamics. High maneuverability and strong armament. Increased aircraft durability. Simple controls.

Disadvantages: Tendency to fall into spin.

almost 24 hours and nobody can or will say if the N model served in the Pacific?

Yes, it did. The P-39N was introduced in mid-1943 to the South Pacific by the USAAF. By this time however, the P-39 was labeled a POS by American pilots and used for ground support.

Too bad, I love using this fighter as much as any soviet pilot. I see why they loved it. It's pretty manverable, fast enough and very powerful guns.
I regard the P-47 as a POS, the P-40 as merely ok, and the P-39 and P-51 as great!

The P-39 was a POS in real life. Just because it is slightly above mediocre in FB doesn't change that. Hopefully Oleg will trash the current flight model of it and give it its historical flight model back in PF. For those who don't know what that means, it means an effective service ceiling of 5,000m instead of 8000m+, brutal stalls and a max dive speed of 650km/h. But I doubt that will happen because in this series planes can only be overmodeled, never realistic or god forbid 1km/h undermodeled http://ubbxforums.ubi.com/images/smiley/16x16_smiley-sad.gif.

Anyways I don't know about the P-39N's service in the USAAF but the P-39D and P-400 did serve in significant numbers. Hopefully those will be added in PF.

5000m is way higher than most battles in IL2, I don't think it's a factor it determining the quality of an aircraft, at least for the eastern front. And it already has brutal stalls, more than any other plain in the game probably.
And jeeze, is the max drive speed really that low? What happened if it reached it?

The elevator would warp beyond repair and result in a nearly uncontrollable plane. They knew it was warping because a couple did make it home after diving this fast (or maybe slow is a better term). The problem was corrected on the Q model I think but the USAAF didn't use that model much.

Keep in mind that the P-39 the Russians eventually wound up with was t the same P-39 we had or used in the same way. I agree with you though.... from all accounts I have read it was a nightmare.... would stall out or flatspin in a heartbeat. More finiky even than the original P-39 in IL2. Maybe Luthier will model the D so they can give it the same messed up performance and everyone can fly the Cats...LOL

Well, I just hope they fix the flight model, if it is as incorrect as you say it is...

I've read about the Q models the most in accounts from Russian pilots, which is not actually substantial (my read of accounts).

I've got Attack of the Airacobras, for what it's worth, but I've laid it aside and have started The Pacific War. Sigh...

If I had time I would like to type up some of the introduction in the P-39 user's manual I bought. It's a bit of simplification to evaluate the P-39 as a POS. Robbed of extended supercharging capabilities it certainly wasn't fit for the high-altitude combat typical of the Pacific. That and the spin characteristics, especially of the early models, were enough for it to get its terrible reputation among American servicemen. But it's a good aircraft, my I remind you that some of the top Soviet aces flew Airacobras and had plenty of confidence in them.

When the Japanese would attack Port Moresby over the Owen Stanley Mountains, P-40s would arise to meet them. The P-39s, unable to climb quickly enough to attain attack altitude, headed West(out to sea) to escape. This earned the P-39 squadrons the sobriquet "The Fishing Fleet".
The P-39 and P-400 pilots were not amused. http://ubbxforums.ubi.com/images/smiley/16x16_smiley-mad.gif

I would hesitate to draw any conclusions about the P-39's RL capabilities based on what we see in FB. Like others, I hope it is more historical in PF.
