In general, while I agree the Oscar (at least the Ib) is not all that good, my general observation is that it is a bit more poor than it out should be. I'm using it almost exclusively in China and Burma, going against mostly those worthless Chinese things and mostly Buffaloes and few Hurricanes. It should at least hold it's own there but it seems as though it doesn't. I've worked my way into May in a couple of my games by now so I have a fairly long term persepective (getting close to the scheduled Oscar upgrades now available in Lemur).

Question is, are the database number for this airframe a bit off or it is the air combat resolution system that is a bit off? My other air combat results "seem" OK to me, indicating a modest database alteration may be the "fix". Those hypothetical bi-plane results Tankerace mentioned would be interesting to see.....

This is the take I had starting this thread.

to evade an Oscar (or a Zero, for that matter) you only had to point your plane downwards.

Beyond all your other observations about the plane's lousy dive and high-speed maneuevrability, the max airspeed IIRC of 310 mph made it one of the easier planes to leave in the dust. To evade one of these a P40, P36, or F4F only had to open the throttle and run don't walk away.



Beyond the top speed is the ability to achieve it in a shorter time span. The Oscar had a noticeably better level acceleration than all of those planes. However, diving acceleration is a completely different matter, and that was where the Oscar lagged far behind the allied types.


Nik:


The Oscar was a lousy performer at high speeds. To say the least. Just like the Zero, the Ki43 suffered from very heavy controls at speeds over 250 IAS, but unlike the A6M the controls were stuck at speeds of 350+. Not to mention that the lightly built airframe didn't keep well the stress of high speed-induced Gs maneouvers, and tended to rip it's wings in such scenarios.



About "me" making plane-to-plane comparisons, is the only way to reach a proper conclussion of "which" plane was the best fighter of WW2.

If it was for success and numbers, the F6F would win hands down, however there were quite better fighters during WW2 if we look at the performances and flying qualities. In a similar way, if we look for success, the Fw190D9 or the Ki-84 should be crap fighters, when a simple look at them shows that the planes were excellent, and the fact that they didn't shine more was because they came into the fight too late and in too little numbers to mean a difference against a vastly more experienced and more numerous enemy.


My comparisons are analytic...I compare performances, flight qualities, vices, advantages and drawbacks. The performance of the Oscar was unimpressive, and its advantages were little compared with its great drawbacks. It's as simple as that.



About air sims. Again, I don't say is the non-plus-ultra, but if you have flown them in a high-fidelity high-realism environment the lessons you extract are THE SAME as the ones extracted in real life, for the planes modelled in a realistic sim perform very similar to those which flew in real life.


Diving out of combat is all fine and dandy...unless by doing so you are abandoning your mission.


Diving at high speed is only the prelude to making a long zoom, winning back altitude in exchange for the speed built on the dive (and zooming is another thing the Oscar was horrible at). It doesn't mean you're abandoning your mission: it means you're using your plane's advantages to win over your adversary.



About the principle target of the Oscar being the Hurricane ,does it surprise you?. Not to me. The hurricane was the ultimate TnB plane in the ETO, and as you said the only veterans at Malay in 1941 were mostly BoB-experienced pilots. The hurricane's only chance to fight a Bf109E in 1940 was to resort to close combat, slow turning, contests as the Messerschmitt was vastly superior as a fighter. When they came to the PTO and started turning vs the Japanese they were kicked out of the sky because the Oscar was a better turner than the Hurricane. And so they got a lot of losses of Hawkers. But it's hardly a suprise if we compare both planes.

BTW the Hurricane was'nt exactly a war winner. In 1940 they saved the day for the RAF because Göring inept orders of tying up the Jagdwaffe to close escort roles instead of sweeping in forward of the bombers, forcing those escorts to close combat, turning contests, where the Hurris excelled over the 109s. Had the Jagdwaffe been allowed to continue with their sweep-style of escorting the Hurricanes would've stood many more losses, for it was a much inferior machine than the Messerschmitt.

by december 1941 the Hurricane was an OBSOLETE plane in the ETO and MTO, used mostly in Jabo roles because as pure fighter it was no match for the 109E , much less for the 109F.

Arguing that many hurricanes were killed by Oscars won't give a lot of feedback to the opinion that the Oscar wasn't crap. A crap fighter which turned better beat the hell up of another crap fighter which was used in close slow combat fights even while it turned worse than their foes.

wow ;).

Yep. strength and weakness.

The Ki-43 was not a great high speed preformer i agree, however i can recall only one incident in Shores where an Oscar's wings ripped off. This was not a common occurance. My objection, which you keep ignoring is that you are only talking about the Ki-43's weak points and not it's strengths. There is also an assumption that all combat is going to occur under conditions unfavorable to the 43. This did not happen.

About "me" making plane-to-plane comparisons, is the only way to reach a proper conclussion of "which" plane was the best fighter of WW2.

This is my point. I am not arguing that the Ki-43 was one of the best fighters of WWII. I am arguing that it was not "Rubbish". It was a competetive plane for it's time and preformed very well. It would not hold it's edges long.....no argument there and like the Zero, it soldiered on long after it's needed replacing but that is more a commentary on the state of the Japanese air industry, not on the plane.

based on your flight simmulator by what i've read. I'm comparing the same stats, however i am also comparing and analysing how the plane was used and preformed in real life combat. The results do not agree with your blanket conclusion that the plane was lousy.

A plane diving out of combat is a non factor until it can return to the fight. Allied pilots did not always have this option depending on the tactical situation.

The Hurricane was certainly not the 1st line plane for the UK by 41, but it was still a decent aircraft and it could use energy tactics. (and did though not as much as it should have...it also didn't have the chance to do so much of the time because of the tactical sitaution) Given that, i doubt even spitfires would have done better. Here the qualities of the Ki-43 would be maximized and with altitude advantage they could control the fight to some extent.

BTW the Hurricane was'nt exactly a war winner.

wow ;).

How many times do i have to say this? I'm not saying the Ki-43 was a war winner either. I'm saying its not "rubbish" and the evidence from the actual combat results speaks of this. Results which are not found in the game.

The plane doesn't suck because the wings didn't fall off? That was not RAM's point. At speeds in excess of 250 mph IAS the controls became logy. Faster than 300 mph and the plane became almost un-maneuverable.
This was not a common occurance. My objection, which you keep ignoring is that you are only talking about the Ki-43's weak points and not it's strengths. There is also an assumption that all combat is going to occur under conditions unfavorable to the 43. This did not happen.

Ram pointed out that in the Malaya-Burma theater the Ki-43 was quite successful against the Hurricrate for the basic reason that the crates were fighting under conditions favorable to the Ki-43. Against faster aircraft that were flown according to their own strengths, the Ki-43 was crap.

RAM's just advocating an objective standard. But if you want to evaluate the relative merits of the Ki-43 vs. its early-war contemporaries, consider that Ki-43s had the snot routinely kicked out of them by the AVG flying P40Cs. I don't think anyone regards the P40 series in general, much less the C model, a state of the art aircraft.

I'd love to see those war winning stats you claim for the Ki-43 however. Are these "claims" or "confirmed kills" by Japanese intel or are they based on Allied unit loss records?
Show me a fellow who rejects statistical analysis a priori and I'll show you a fellow who has no knowledge of statistics.

If that had happened....i would agree, but it didn't. See Shores... "Bloody shambles" The Ki-43 and 27 held their own against the AVG during the Burma campaign.

confirmed by research on both sides of the fight.

Structural weakness was inherent. A plane which disintegrates when hit isn't good. A plane which disintegrates when pulling a high-G maneouver, neither is good. There were more instances of Oscars falling down because structural weakness. I'll have to dig up into all the saved stuff I have in my PC at home. However that's about 300 miles from where I'm sitting now, so will have to wait.


This was not a common occurance. My objection, which you keep ignoring is that you are only talking about the Ki-43's weak points and not it's strengths.

That's not true, nik. I've talked about the Oscar's strenghts too. In your last message you quoted me talking about the Oscar acceleration.

What I'm trying to say is that the strenghts of the Oscars were of relatively minor importance for WW2-vintage air combat. Acceleration and low speed turnrate are minor advantages if you compare them with dive&zoom ability and hispeed maneouvering. As I said previously, the Oscar's drawbacks hughely shadowed it's strenghts...the pluses couldn't overcome the penalties of fighting at high speeds. Given that in WW2 hispeed combat was the key for success, the Oscar simply sucked as a fighter plane, no matter it had fields of performance where it excelled.




This is my point. I am not arguing that the Ki-43 was one of the best fighters of WWII. I am arguing that it was not "Rubbish". It was a competetive plane for it's time and preformed very well. It would not hold it's edges long.....no argument there and like the Zero, it soldiered on long after it's needed replacing but that is more a commentary on the state of the Japanese air industry, not on the plane.

maybe you're taking me wrong. I'm not saying that you think the Oscar was the best fighter of WW2. I'm talking about the objective way I'm comparing planes between each other to find out which one was better. However, the same method used for finding out the best fighters of WW2 can be used, reversed, to find out the WORSE fighters of WW2. And the Oscar ranks very high in that particular "competition".



based on your flight simmulator by what i've read. I'm comparing the same stats, however i am also comparing and analysing how the plane was used and preformed in real life combat. The results do not agree with your blanket conclusion that the plane was lousy.


Nik, I would thank you stopping saying that my conclusion are blanket. You might or not be in agreement with them, but up to this point I've backed up my position with enough data to prove that I'm not saying this out of the blue. I have a quite wide knowledge of WW2 air combat, tactics, engineering and performances. Please keep that in mind.


On the other topic, again I repeat: Real air combat didn't always throw objective prove about each plane's real quality. As well as the Fw190D9 or the Ki84 didn't got the numbers to back up their excellence (even while THEY WERE excellent) there were some planes in WW2 that performed and got numbers well beyond their true qualites as fighters because the extreme circumstances of the enemy they fought. The Oscar is one example of this. What do K/D numbers prove?...in fact, nothing. The Dora-9 was a superb fighter, the Ki-84 was a wonderful fighter, none of them both got exactly great results...that does mean that they weren't excellent?...What does true numbers prove?

if you take real life K/D ratios of air forces flying in a ballanced scenario numerically talking, and with pilots of good skill in both sides, then yes, they do prove a lot. But if you take real life K/D ratios of air forces flying against unexperienced enemies flying in scrap-metal things with wings, there isn't a lot to extract from them.


I have flown air sims and under certain conditions i can duplicate the feats described...however i have found that once you move away from the aritificial duel type situations and get into more sophisticated mission profiles, it is not nearly so cut and dry as you preport.


I think you're talking about boxed sims where you fly vs the AI. Aces High is a MMOG where there's NO Artificial intelligence involved. You go up, you fight against HUMAN ENEMIES, you die or you come back. In such an environment, full of exceptional "virtual" pilots if you don't use real life tactics, and you use them well, you're toast in less than 5 minutes.

Regardless.... an air simm is no substitute for research.


never said otherwise. I said simulators add first-hand feedback of WW2 combat tactics applied.

Something you wouldn't ever get reading a book, for instance. Books aren't substitutes for air simulation experience, either.


They're different things, and the most desirable thing is learning from both.


A plane diving out of combat is a non factor until it can return to the fight. Allied pilots did not always have this option depending on the tactical situation.


but they sometimes had it. You said that diving from an enemy meant diverting out of the fight for good. I say that's not always true. Diving can be the initial move for a disengagement, or the initial move for coming back with the advantage after a long zoom and buildup of Energy. Tactical situations sometimes prevented the aircraft to come back, but sometimes not. And in any case I'd rather be in a plane that gives me a high chance to avoid an enemy if I see him in time, that in one that doesn't give that chance to me.


The Hurricane was certainly not the 1st line plane for the UK by 41, but it was still a decent aircraft and it could use energy tactics. (and did though not as much as it should have...it also didn't have the chance to do so much of the time because of the tactical sitaution)


The Hurricane was obsolescent by late 1940, and by 1942 was already obsolete. I would like to know what do you call a "decent aircraft" ;).

It could use energy tactics, but the RAF pilots always tended to use turning tactics when meeting a foe, something inherited from european experience where british aircraft had better low speed maneouverability and turning that their german counterparts. If the pilot had seen combat in the ETO, this was even more true.

When confronted with the Oscar the Hurri pilots always tended to enter close fights, and in those fights they were dead meat against the Oscars. Once they realized it and resorted to E-fighting the losses started to go down...still they lost quite a number, but that is because the Hurricane was a very dated design by that time, and the E-fighting techniques and tactics didn't fit well with that aircraft, either (even while it was better than the Oscar in that department).

Given that, i doubt even spitfires would have done better. Here the qualities of the Ki-43 would be maximized and with altitude advantage they could control the fight to some extent.


The spitfire was a much faster plane than the Oscar and had similar or better climbrate and acceleration (depending on the version of the Spit we're talking about). The Spit would've had a much better result than a hurricane...just as the soviets would've had much better results in 1941 with an air force composed of La5s instead of I-16s.


How many times do i have to say this? I'm not saying the Ki-43 was a war winner either. I'm saying its not "rubbish" and the evidence from the actual combat results speaks of this. Results which are not found in the game.

I know what you want to say, I already explained it before.

And evidence of actual combat results doesn't give objective facts when that combat didn't happen between similar numbers and similar pilots quality wise, as I already said. Factual data sometimes is VERY subjective because of the particular circumstances of the war at any given moment.

And anyway those combat reports don't speak so well of the Oscar. At least not from the moment when the Oscar faced experienced pilots in capable planes instead of lousy riders with winged garbage cans...


and please, lighten up the mood a bit, Nik. We're discussing about a plane that stopped flying 59 years ago, not about the end of the world ;). This is intended to be a friendly debate, not a heated discussion...isn't it? :)

See Shores... "Bloody shambles" The Ki-43 and 27 held their own against the AVG during the Burma campaign.

And they still lost far more Ki-43s vs the AVG through April 1941 for each P40 downed. If that's "holding their own" then the objective standard has nothing to do with aircraft shot down or with the performance characteristics of the planes. Possibly this has to do with the fact that the Japanese ultimately gained all of their short term strategic objectives, and rather quickly at that. Of course, one would hardly expect otherwise given the resources and strategic postion at their disposal.

the oscar was a good plane when it was designed 1939, by 1942 and onward it's defiency started to show. It only true strenght was it' manueverablity at low speed, which was unmatch by allied planes. Also, it's armament was also lacking 2 machine gun(barely better than a WWI Biplane), so oscar pilot had to be truely a marksmen to down contempary allied fighter/bombers w/ their armor and durability. Even if the oscar could manuever into position. HOWEVER, the allied pilots eventually counter that weakness by simply refusing to fight on OSCAR's terms(low speed dogfitghts).

WITP calculate several factors in determining the outcome of air-to-air combat(mv, spd, guns, dur, pilot exp, fat, etc.,) Unfortunately the OSCAR manueverability(34) is only one factor AND eventually many allied 2nd gen planes are almost or more manueverable(34-37) as the OSCAR. The more i play this game especially as japanese, the more i realize the futility and hopelessness of the jap situation. Looking back, they were crazy-as in certifited looney bin, to even THINK even had a remote chance of a statelmate. Talk about bad call at every level(strategic/plane design/production/etc.,) At least the German had a decent chance of beating England/france. Even German never thought they could be the US on their own.

Hi all,

Hmm, quite a few things.

The world is probably coming to an end soon as I completely agree with Nikademus' points.
The Hurri2 was not particularly obsolete in the PTO in '41-'42. It was essentially the most maneuverable aircraft the Allies had in the PTO at this time. The Hurris only real weakness was its top speed.

I essentially hate the P40 line but you have to give it credit for tough construction and high speed. Boom & zoom was of questionable value at this stage of the war defensively as the allied aircraft had limited climb rates.
Sure, you stayed alive but you just left the battle and that Oscar is now attacking your bombers or escorting its own bombers succesfully.

Someone mentioned the Oscars poor top speed compared to P36, P40, F4f. That is a bad comparison as the F4f as far as i know never fought an Oscar, and the -4 could only do 318 with a much slower acceleration than the Oscar.
The P36, depending on armour or lack of, flew from 322 to 348. The 322, 328 speed P36s again were only slightly better than the Oscar and again with low acceleration.
Only the P40 shows the ability to dictate when & where to an Oscar. In SE Asia in '41-'42 there were not that many P40s.

One gaff everyone still makes is like Gary Grigsby in BoB giving the Hurri & Spit a lower maneuver value because of their carberateur. That problem was fixed by the end of July '40 by Rolls Royce field replace kits.
Just a Battle of Britain legend that will not die.

Same with high speed maneuverability problems.
Essentially every country made changes in thier aircraft even without changing model numbers.

The Oscar & Zero were both known to have high speed control problems before the war started. Like several Allied aircraft i could name.
Horikoshi made various changes to the aircraft which eliminated virtually all of these problems. On the Zero this ended up creating a weird vibration effect that no one, as far as i know, has ever been able to really explain.

The Nakajima team was more sucessfull than the Mitsubishi
team in their quest to rid the Oscar of high speed control problems and by April-May '42 they had done so.
I have read of the American test of an Oscar 2 from New Guinea saying that it still had heavy controls and i do not know what to say.
I have read the Nakajima accounts of the changes they made
and their test pilots comments and itt seemed like they fixed the majority of the problem.

Probaly the plane that had the biggest problem with controls was the Me109. Never was fixed as half the problem was the narrow cockpit, same problem the P39 had.

For my next version i am eliminating many of the unused guns in the database and i am going to create nose guns that are otherwise identical with a bit higher accuracy.
Change things a bit.

Is a strange mix of agreement and disagreement there. By saying that the Hurri2 wasn't "particularly obsolete" in the PTO in 1941-42 I guess you're pointing out that in the ETO they were badly outmatched by the german fighters. However if a plane which at the ETO stands little chance, but in the PTO was "not particularly obsolete" means the japanese oposition was of much less quality as that of the german.

In short: what your sentences seem to say say implicitly is that the Ki-43 compared very poorly with the best models England and Germany had at the moment (Spitfires, 109s and 190s). So the Ki-43 could hardly be called a "good" fighter for 1941-42...

I essentially hate the P40 line but you have to give it credit for tough construction and high speed. Boom & zoom was of questionable value at this stage of the war defensively as the allied aircraft had limited climb rates.

As I told Nikademus before, that may be true sometimes, but the rest of the times is not. Diving away doesn't mean you're disengaging. Sometimes yes, but not all the times.

Diving away means you may be gaining separation to build up your energy by zooming back, and a possible tactical advantage. If the enemy can't follow your dive he's out of options to follow and kill you.

If the enemy leaves the chase, then you're free to zoom, win back altitude for the speed you've won in the dive, and re-enter the fight at will after some minutes of winning energy and, if possible, tactical advantage.

if the enemy doesn't leave the chase, then he can't be killing your bombers or escorting his own's...as he is trying to keep pace with you...but as you're in a faster plane with much better diving qualities, he won't catch you.

it's a no-no for the Oscar here.

Someone mentioned the Oscars poor top speed compared to P36, P40, F4f. That is a bad comparison as the F4f as far as i know never fought an Oscar, and the -4 could only do 318 with a much slower acceleration than the Oscar.

Only the P40 shows the ability to dictate when & where to an Oscar. In SE Asia in '41-'42 there were not that many P40s.


which was exactly the reason why the Oscar didn't suck from the very start of the war. They were flown by very competent battle hardened pilots against a very low quality opponent flying in flying coffee cups...

One gaff everyone still makes is like Gary Grigsby in BoB giving the Hurri & Spit a lower maneuver value because of their carberateur. That problem was fixed by the end of July '40 by Rolls Royce field replace kits.

That's not really true. Floating carburator problems were not adressed until mid-42 with the introduction of the Spitfire IX with modifications made into the carburator to ensure the engine cutted for the first seconds of a -G maneouver (if the move was longer, the engine still cutted...the Merlins never had the highly efficient direct injection of the 109s which allowed for any kind of negative G maneouves). The Spitfires V still had that problem, and until 1943 (when all the spitfire fleet was retrofitted with them) there were quite some planes with the inverted G engine cutting. Many Spitfire Vs were still flying in 1943 (in fact many of them did see service until european V-day), so that was indeed still a trouble for 1942.

Same with high speed maneuverability problems.
Essentially every country made changes in thier aircraft even without changing model numbers.

The Oscar & Zero were both known to have high speed control problems before the war started. Like several Allied aircraft i could name.

I don't think any allied aircraft by 1941 had the horrible high speed controlability problems the zero and Oscar had. If you think otherwise, I would like to hear to which plane do you refer :).

Horikoshi made various changes to the aircraft which eliminated virtually all of these problems. On the Zero this ended up creating a weird vibration effect that no one, as far as i know, has ever been able to really explain.


They didn't eventually eliminate the problems. They somehow made them less extreme. The a6M5 could dive at much higher speeds than the A6M2...however it was still a lousy plane on high speeds because the controls ,albeit not stiff as concrete anymore at high Indicated speeds, were still very hard.

The Nakajima team was more sucessfull than the Mitsubishi
team in their quest to rid the Oscar of high speed control problems and by April-May '42 they had done so.
I have read of the American test of an Oscar 2 from New Guinea saying that it still had heavy controls and i do not know what to say.
I have read the Nakajima accounts of the changes they made
and their test pilots comments and itt seemed like they fixed the majority of the problem.


I also have read that the Oscar never got its hispeed control problems fixed. If you can give me the changes the japanese did to the plane, and the source from where your data comes, then we might be able to discuss that more in-depth :).


Probaly the plane that had the biggest problem with controls was the Me109. Never was fixed as half the problem was the narrow cockpit, same problem the P39 had.


that's not what the finnish and germans said about the 109. The Messerschmitts up to the early G6 had problems with stiff aileron contros at speeds over 400mph IAS, however aileron and rudder authority were complete. However ,from the late G6 onwards (late G6, G14, G10, K4) the ailerons of the 109s had flettner tabs which greatly helped high speed aileron controlability and reduced a lot the stick forces required to roll the plane at those speeds.

Just a point of data:

P-47D Max range with Drop tanks 1800 miles. '
P-51D Max range with Drop tanks 1650 miles.
P-38J Max Range with drop tanks 2260 (ferry range) G model max range with large tanks was 1950 miles.


The P-51 was chosen as the Escort fighter not because the other planes could not make the trip, but the P-47 had a lack of Drop tanks, and early on were using smaller British tanks. The P-38 could do it no problem but it was a very expensive plane to build and the Numbers were never there for what needed to be done with escort duties. The P-51 was cheap to build, and fast to build. The fact that it was a decent fighter was secondary. It was inferior in range to both of its contemporaries. For Ground attack and over water flight the P-38 and P-47 were much better suited to the task. The P-38 especially for over water flights had a redundancy with two engines. It would fly and fly well on only one. The P-47 was just a tank. It has a legendary history of taking HUGE amounts of battle damage and still making it home. Combined with the P-47's much heavier armament than either the P-38 or P-51 makes the P-47 the best Ground attack aircraft. The Big Radial engine would work missing entire cylinders. Those 8 fifty caliber machine guns were one of the heaviest in the US arsenal. Combined with the ability to carry 10 HVAR 5" rockets and 1500 lbs of bombs. (The Rockets had to be fired before the guns or the firing mechanisms may be damaged by the ejection ports of the guns.) The P-38 also carried a large attack load, two 2000 lb bombs, or 10 HVAR 5" rockets and two 500 lb bombs.

In air to Air combat believe it or not the P-47 was the top dog of the American fighters here. At the normal combat altitudes it was faster and more maneuverable than both of the other planes. Next would be the P-38 the later models had hydraulic assisted control surfaces and this allowed very good high-speed maneuverability and very good centrally mounted guns.

The P-51 helped win the war but it was not the greatest plane ever made as some claim, same as the Spitfire was not.

Not what the USAF Museum says. So you're saying their records are falsified? Just wondering, what sources do you suggest for accurate reporting.

Then I can change my information base.[8D]

Wasn't there a Pre-RR Merlin vesrion of the P-51 that the US exported to Britain in some numbers. What did the Brits do with them anyway?

You mean the Allison engined P-51As? They were used for ground attack, because there Allison engines were crappy at high altitude.

Yes there was it was but it had an Allison engine. It was used in Armed tactical recon. The Allison had poor High altitude performance and was reduced to low level uses. It was called teh Mustang IA and had cannon instead of machineguns (4 Hispano 20 mm vs. 40r 6 50 cals.) The US used it as P-51A and it was a dive bomber. It carried 2 1000 lb bombs.

There was a P-51A version driven by a 2-stage supecharged Allison engine. Its performance was medicore for the day. Most of them were used in N.Africa in a ground attack mode IIRC.

The P-51 was hands down the best high altitude escort fighter of the war and the best for its stipulated purpose: bomber escort. With drop tanks it had a greater range than any other Allied fighter. Most USAAF sources acknowledge its superiority among the late war USAAF fighters *as fighters.*

As a ground attack plane it left much to be desired. At low altitude it was not the best performer, and its liquid cooled engine with oversized oil cooler underneath made it relatively vulnerable to ground fire. In ground attack, the P-47 was hands down the better plane. P-47 was also pretty good as a high-altitude fighter, but not the primus inter pares as was the P-51. That is why the late war arrival of the hinkey but fast Japanese interceptors was met with the P-51s who, in the Japanese own words, pretty much swept the Japanese interceptors from the sky.

The P-38 is not my idea of a viable candidate for the best fighter in the USAAF in any role. But for the cross-ocean campaign in the vicinity of the Solomons and late war action in the Philippines it was a very good a.c. because of engine redundancy. And the Japanese couldn't really mount an effective defense against good fighters, so pretty much any of the above trumped anything put in the sky by the Japanese.

Sorry Mdiehl,

But I have to disagree here. the P-51 had an inferior range to both the P-47D and P-38 with drop tanks. As I posted above it was 1650 miles max range for teh P-51D, 1800 miles with drop tanks for teh P-47D and teh P-38J/L was 2200 miles Ferry range and teh G model with large tanks ahd a range of 1950 miles.

The P-47Nwich was used int eh Pacific had the astounding range of 2350 miles with drop tanks, with internal fuel it was 800 Miles. There were 1816 N models made. It was used to escort B-29's from Saipan.

Edit: Also just throwing it out there the Jug flew 546,000 sorties during WWII and had the loss rate of 0.7% per sortie. That is just amazing considering the type of mission they flew with teh 9th AF and in teh PTO as Close air support.
