Title: A case for the P-63

A case for the P-63 in Aces High

Note: please do not hijack this thread with discussions of your pet or 'more worthy' aircraft. Those should be discussed in seperate threads. Thank you.  :salute

     While the single seat, single engine, liquid cooled V-12s were the premier fighters for Great Britain, Germany, and Italy, The U.S. Struggled to compete with its V-12 powered offerings at the outset of the war in Europe. The biggest factor in that struggle was the Allison 1710, the only V-12 available to American Manufacturers, which in 1941 was under developed, and underpowered. North American Aviation made the decision to abandon Allison for the British developed Merlin, hence the most successful V-12 powered American Fighter of the war, the Mustang, can't be considered all American from a design and engineering stand point. The Bell P-63 Kingcobra was the last and best attempt by American engineers to develop a single seat, single engine, V-12 powered fighter.   
     The second generation of Bell's mid-engine single seat fighter concept, the Kingcobra, possessed impressive performance numbers:
Climb Rate [ref 1]

                                    P-63A-1      P-47D-20        P-38J-15          P-51B-5
War Emergency Power   60"/3000 rpm   56"/2700 rpm   60"/3000 rpm   67"/3000 rpm
Speed @ 10,000 ft           372                   367                 383               395

Speed @ 25,000 ft           397                   414                 420               424
Speed @ 30,000 ft           389                   423                 417               433
*note: This data was for these planes tested during the same flight test. As such its relative values are accurate, but actual values may differ from other flight test results. The P-63A with WEP rating of 1325 HP. The C' model P-63 could run with 80" of manifold pressure, producing 1800 HP. No top speed test data for C' model found to date. [ref 3]

Roll Rate  & Turn performance.
     I'm still searching for a source of the objective numbers, which are not quoted in Matthews book, but this quote from the NACA test results [ref 4]: "the maximum rate of roll possible with full aileron deflection is exceeded by few current planes for which comparable data are available.", indicated the roll rate was excellent. Similarly, but much less objectively, these excerpts give an indication of turn performance. "With respect to maneuverability, the Kingcobra received high marks from the Air Force. The Kingcobra also consistently turned tighter circles than the other three fighters [P-51B-5, P-38J-15, P-47D-20]. In dives tests the Kingcobra had a slight advantage over the P-38. In full power dives the P-47 and the P-51 showed a marked advantage over the P-63. When subjected to zoom tests at full power, the Kingcobra was better than the P-47 and the P-38. [ref 5]
 
     Good climb rate, excellent roll rate, good turn performance, good top speed, so why was the Kingcobra pass up by the U.S. Army?
In Europe the fighter mission had become a very specialized version of the air superiority role, consisting of very long range fighter sweeps. The qualities preferred were a large combat radius, and top speed, and a gun package ideal for killing fast maneuverable fighter aircraft. The P-63 is a poor match to the Mustang in combat radius, and its gun package has only two or four .50 caliber machine guns for the anti-fighter roll. The 37mm with 58 rounds, was a less than ideal weapon against evasive, agile fighters. The Mustang was better suited to the specific mission the Army was most interested in, in late 1943. Coupled with the need to provide planes to the Russians, and the Russians familiarity with Bell aircraft and the mid-engine layout of the Bell fighters, the decision to send the P-63 to the Russians, was a practical, and logical one, more than it was proof of a lack capability on the part of the P-63. On paper the P-63 seems to have a different attribute mix than the Mustang. When assessed versus the full variety of missions that play out in the MA, the P-63 would be better than the Mustang in the anti-bomber roll, ground attack, and it's better maneuverability but less than ideal gun package would make for a fun dog fighter, similar to the 109-K4
AP ammo might make it a good tank buster, but the game would employ Russian designation P-63s and they were not issues AP rounds [ref 6]
One of the great parts about Aces High is the ability to assess all the planes against each other in a variety of roles. Some of those roles will be outside of  how  they earned their reputations during the war. Messerschmitts dog fighting Zeros, Spitfires vs Corsairs. P-51s attacking large bomber formations instead of defending them.  In such matchups the Aces High players get a unique opportunity to judge whether the reputations of these planes outpaces their actual ability, or perhaps in the case of the P-63, whether the reputation as a sub-par aircraft is a complete misunderstanding of the facts surrounding its deployment to the eastern front.   

     The case for the P-63 in Aces High II is more than just having a unique new fighter to play with. The P-63 has significance in it's place in history as the platform that carried the only two stage supercharged Allison V-12 which finally produced more power at all altitudes than the Merlin, while the airframe seems to have finally delivered on the promise of mid-engine maneuverability, and big cannon firepower. To see for ourselves if the last and best attempt by American engineers to develop a single seat, single engine, V-12 powered fighter was just another weapons system footnote as many are lead to believe, or an under appreciated hidden jewel in the arsenal of democracy. Aces High would be the perfect laboratory to prove what Allison and Bell were truly capable of, after they were given sufficient time and resources to develop their concepts to their full potential after getting a late start due to America's slow commitment in the 1930 to prepare for war.

Did pretty good in Soviet service and it should be added to the game as well.  Even though it's a US built plane, it would still give the Soviets a plane to help fill out the plane set.

This is a reasonable wish IMO...

1. It saw combat
2. It was in squadron strength
3. Would fill in some of the Russian plane set, as AKAK stated

Hop in the 39Q and have fun with it :)

That's a bit strong I think Karnak.  Gotta believe folks can have a strong interest for a bird and it doesn't make it nationalism.  Kinda like folks who like Mossies, or Spit XIIs, or Beaufighters for that matter :)

That 63 has been in his Avatar a long time.  It is a pretty bird.

Nationalism is evil.  Patriotism is good, but Nationalism should be opposed always.

As far as the P-63, it has practically no place in a WWII sim.  The aircraft was a complete non-factor.  Asking for it to be added when the US planeset is well rounded and many key aircraft that played major roles in WWII are still absent is absurd.

It was flown only by the Soviets. It wouldn't fill out the U.S. plane set. Read more.

I really don't see this as an addition to the US plane set since it was used by the Soviets and it would compliment the existing Soviet plane set.

If I remember correctly when the P-63 was discussed in the past it was noted that it did not "officially" see combat because it was given to the Russians to use exclusively in the fight against Japan that the soviets were expected to begin shortly after the defeat of Germany. How many people believe that Uncle Joe did exactly as he was told and only allowed the P-63 to be deployed in the far east?

This point always starts a lot of controversy, because of the assumptions and rumors around P-63 use in lieu of hard evidence. But since the P-63 significance and use, or lack there of,  by the soviets is always the reason given for non-inclusion, I will contribute the one piece of hard evidence I could find.

In "Attack of the Airacobras" by Dimitri Loza [ don't have it handy, so I'll edit and add Page ref later] he Chronicles the use of the Bell aircraft against the Germans on the eastern front, mostly the P-39. The book quotes from fighter pilot Alexander Pokryshkin, and records showing periodic squadron strengths of operational aircraft, which at one point in 1944 for squadrons fighting on the Eastern front, shows the P-63 is listed as making up 45% of operational aircraft in the squad, and the P-39 making up the rest. Best I could find so far.

4 GIAP was an "Official P-39 Squadron", while actually flying P-63's in 1944.

So we can't bring up other "pets" in your pet discussion?  :lol  I know you're tired of being caught low and slow in your favorite ride against the Spixteens and 190s, but honestly, the P-63 export version was mediocre at best. By the time it started being shipped out, the Russians had already started gaining air superiority with their own fighters.

Were all P-63s produced with the M10 cannon (some type of modified M4 I assume) capable of holding 58 rounds of 37mm or was it just a subset of the A series? Also, would we be looking for the A or C series? The production numbers are pretty closely divided between these variants with the C having some engine upgrades and wing modifications.

While there are some P-39 experts in the area, does anyone know what the historical roll rate was on the P-39 and how it stacks up compared to what we have in game? The in game 39 seems to really suffer in roll rate when it is slow (<150). It almost helps when I get a flap shot out so I at least have good roll rate in one direction. :joystick:

Damn... I knew it was too soon to pack up my P-39/63 book.

If I remember correctly the P-39 wasn't known for having a stellar rate of roll.  I'm in the process of moving over the next few weeks and if you're still interested shoot me a PM early next month and I'll be happy to go back and check and see if I can find anything.

Kingcobras, attaining 421 mph (678 km/h) at 24,100 ft (7,300 m).

Deliveries of production P-63As began in October 1943. The USAAF concluded the Kingcobra was inferior to the Mustang, and declined to order larger quantities. American allies, particularly the Soviet Union, had a great need for fighter aircraft, however, and the Soviets were already the largest users of the Airacobra. Therefore, the Kingcobra was ordered into production to be delivered under Lend-Lease. In February 1944, the Soviet government sent a highly experienced test pilot, Andrey G. Kochetkov, and an aviation engineer, Fyodor P. Suprun, to the Bell factories to participate in the development of the first production variant, the P-63A. Initially ignored by Bell engineers, Kochetkov's expert testing of the machine's spin characteristics (which led to airframe buckling) eventually led to a significant Soviet role in the development. After flat spin recovery proved impossible, and upon Kochetkov's making a final recommendation that pilots should bail out upon entering such a spin, he received a commendation from the Irving Parachute Company. The Kingcobra’s maximum aft CG was moved ahead to facilitate recovery from spins.

P-63A-8, SN 269261, was extensively tested in what was then the world's largest wind tunnel. Soviet input was significant. With the Soviet Union being the largest buyer of the aircraft, Bell was quick to implement their suggestions. The vast majority of the changes in the A sub-variants were a direct result of Soviet input, e.g. increased pilot armor and fuselage hardpoint on the A-5, underwing hardpoints and extra fuel tanks on the A-6, etc. The Soviet Union even experimented with ski landing gear for the P-63A-6, but this never reached production. Most significantly, Soviet input resulted in moving the main cannon forward, favorably changing the center of gravity, and increasing its ammo load from 30 to 58 rounds for the A-9 variant. The P-63 had an impressive roll rate, besting the P-47, P-40, N1K2 and P-51 with a rate of 110° per second at 275 mph (443 km/h).

By the time it started being shipped out, the Russians had already started gaining air superiority with their own fighters.
LMAO here is another take...


If one considers 420 mph at 21,000 feet poor performance. Let's face it, 95% of all engagements in AH2 are below 20,000 feet.

The answer to the La-7 is the P-63A Kingcobra. Similar climb and low-level speed, but the P-63 is nearly as maneuverable as the FM-2. Add four .50 cal MGs and a 37mm cannon.

These two fighters would be very equal except that the La-7 could not afford to turn-fight with the P-63, and the P-63 has a big range advantage, plus the ability to haul a 500 pound bomb (or a drop tank).

So, how fast does the P-63A climb? Well, for comparison, let's look at the F6F-5. It requires 7.7 minutes to climb to 15,000 feet. In contrast, the P-63A can get to 25,000 feet in 7.3 minutes! The P-51D requires near twice as long (13 minutes) to reach 30,000 feet.

When the Soviets first began flying the P-63, they found the tail to be weaker than that of the P-39. Bell developed a kit for strengthening the tail and Bell technicians made field modifications to those planes in service. That change was immediately incorporated into the production line as well.

Pilots who flew the P-63, and had time in the other major U.S. types, generally agreed that the P-63 was far and away the best performer at low to medium altitudes. Not surprising, the pilots flying it at the Joint Fighter Conference differed from rave reviews to outright dislike (the only thing the JFC ever proved was that every monkey prefers his own banana).

Since more than 3,300 P-63s were built, and it saw combat (with the Free French and Soviets) in far greater numbers than the F4U-1C or Ta 152H, I think it would be an excellent candidate for inclusion in the AH2 plane-set someday.

My regards,

Widewing
Yea I'll go with widewing's opinion.

The 39 was noted for exceptionally light controls. I think I read somewhere that is why some pilots got into trouble with it... it doesn't like ham fisted pilots.
