Hard to believe the N had a higher ceiling than Corsairs and Hellcats.
Since the Hellcat was considered the unquestioned master of the Japanese planes, the P-39N should have been able to handle Zeros like the Hellcat. Zeros were 330-340mph planes, Hellcats and P-39Ns were 40-50mph faster at all altitudes.
Nope, it was your ballgame, in your front yard, with all the players from your teams, and all the heroes were yours. RIP. The rest of the free world thanks you.The story of the fight across the Owen Stanley ranges is not a fight known well to the US.
Not this forum obviously, most people here have studied their history, but I get the impression that a lot of American people don't realise they weren't the only ones fighting the Japanese.
Would that be right?
That's because it really didn't. In most reference books and other well respected sources the F6F-3 will show a reported service ceiling anywhere between 37,300 - 38,400 feet, and I've seen Navy reports showing as high as 38,600 feet in military power (52" Hg) with an overload weight of 12,680lbs. The report you are referencing shows a particular P-39N (s/n 42-4400) at 7,300lbs with a ceiling of 38,500 feet. How is that any kind of real advantage? Plus, besides the occasional airplane doing reconnaissance work, who the heck was fighting at 38,000 feet anyway during WWII????
P-39N in production between December '42 and April '44 was faster and climbed faster at all altitudes than the Spitfire V. The Spitfire IX was superior in speed and climb to the P-39N and entered full series production about the same time. The comparison I'm making is between the P-39N and the German fighters. Everyone else seems to have me in an argument over the Spitfire.
Regarding fuel, the P-39N carried 120 internal and the Spitfire carried 100 US gallons. During N production the Russians requested that we start deleting the wing guns from the factory and reducing internal fuel capacity. The N and Q gradually reduced capacity to as little as 86 gallons. The wing guns stayed until the late Q models. Apparently less fuel and no wing armament worked for them.
After completion of the first 166 P-39Ns, the USAAF requested that four fuel cells be removed in order to reduce the internal fuel capacity from 120 to 87 US gallons, and so to reduce the maximum permissible gross weight from 9100 lbs to 8750 lbs. This kept weight down, but unfortunately it also restricted range. Therefore, kits were provided that allowed the four fuel cells to be refitted in the field.
Japan was a "victim" of its own compulsion to be a first rate world power despite its lack of domestic natural resources to do so. This put it on an inevitable collision course with those empires who had beaten them to it and were already exploiting pretty much all of the available resources.Yes, and I would go as far as to say that they know very little if any of the roll America played there as well. To them, Imperial Japan was basically a "victim" of American foreign policy and that they were forced to attack the western powers as they had no other recourse but to do so. Utter nonsense.
The UK and USA declared war on Japan within hours of each other because both had been attacked, in addition to Pearl Harbour the Japanese attacked Malaya, Singapore and Hong Kong.Japan was a "victim" of its own compulsion to be a first rate world power despite its lack of domestic natural resources to do so. This put it on an inevitable collision course with those empires who had beaten them to it and were already exploiting pretty much all of the available resources.
I find it ironic that the US, arguably the least "imperial" of the major powers, would be the first to step on the tripwire and set off the explosion. If Hitler hadn't had Europe tied up in knots it might have been someone else that set it off. Britain, France, and the Netherlands all had empires in the area.

Notice that the P-39 is doing 400mph at 16000'? Ever see that in any reference book?DO you have ANY evidence that combat weight was at half fuel? You keep repeating but give no proof.
IN fact we may both be wrong.

Gross weights of Ns at 7393.7 and 7395.? I am not going to argue over a few pounds but both Ns are shown with 87 gallons of fuel.
Many books say that the "N"s were produced with 87 gallon capacity. Kits were supplied to bring them back to 120 gallons that could be installed in the field.
Military power was 44.5in of MAP, full WEP was 57in. this test was done at 50.5in (take-off power) until the supercharger could no longer supply that pressure.
Not WEP but not military power either. and then we have.

P-39 Q at 7200lbs needs 9.3 minutes to get to 25,000ft using take off power for the first 5 minutes, and uses 33 gallons of it's 87 gallons just to get there.
P-39Q at 7600lbs needs 10.1 minutes to get to 25,000ft using take off power for the first 5 minutes and uses 34 gallons to get there.
the under wing pods created that much drag?????
Elapsed time to altitude was at 0 degrees C or 32 degrees F.
we also have the penciled in chart saying 4.1 minutes to 14,600ft?
and
View attachment 487160
about 300lbs heavier (120 gals fuel?) but even using MIlitary power for the first few minutes ( and NO drag from wing guns) needs over 9 minutes to get to 25,000ft.
We also have the basic Bf 109G climbing to 7000 meters ( 22,966ft) in 8 minutes so your p-39 had better be on watch. which climbed faster where I don't know.
I would also note that a plain Spitfire MK V using 16lbs boost (below 8,800ft) can make it to 24,000ft in 8.15 mins using a single speed single stage supercharger.
Now just for balancing things out a bit, the super P-39N is climbing at 1940fp at 25,000ft, the Spitfire V is climbing at 1740fps at 24,000ft and the 109G (basic?) is climbing at at least 2066 at 22,966.
A P-39Q at 7871lbs was climbing at 1570fpm at 25,000.
The P-39 has to be very careful about weights and altitude or it can get into big trouble.
Falling into the ocean because you don't have enough fuel can also ruin a pilots day
Just asking, how do you get the whole graph to appear in your post? Everytime I try to upload a graph it attaches as a pdf that must be opened. Yours shows up already open. Thanks in advance for your help.
Keep in mind a few salient points, first these were older P-39s with the lower rated engine and way too much weight. With the ever present drop tank their combat ceiling (altitude above which any plane will climb at only 1000fpm or less) was about 18000'. The Bettys came in at between 18000' and 22000' with their Zero escort at about 24000'. These older P-39s (D,F,K,L) could have easily been modified in the field by simply removing the 4 x .30 wing guns along with their mounts, chargers heaters and ammunition boxes (and of course the ammo itself which was the heaviest component) and these planes would climb with the P-38s that, by the way, were not even available until very late in the year.

Oh, the P-39 drove like a limousine on the ground, which must have been comforting to the pilots struggling to reach an altitude where they could engage the enemy aircraft sent to bomb the shit out of the airfield.
No, he's there to shield poor Allison!Yes, the only problem is that the main armor ( more than 1400 pounds) is behind, and not in front, of the Pilot...
I thought he was there to resolve a CoG issue, in lieu of ammunition?No, he's there to shield poor Allison!
