Where the tool comes in here is how much potential does it have to be so adapted, arguably.

As often, it is not the tool that is decisive, but the professionalism and the correct way of using it. So good pilots and right tactics helped much. Play on one's strenghts and enemy's weaknesses. And don't underestimate your opponent.
That is a fair point, but when you look at the bombers that were doing the most damage in China and the Pacific Theater up to early 1944, it wasn't so much the big bad B-17, it was fighters like P-40s and Hurricanes, in the Pacific it was dive bombers like SBDs (and the Army verison, A-24) and torpedo bombers like TBFs, it was light bombers like Hudsons and A-20s, Blenheims and Beuaforts, Beaufighters (as strafers), medium bombers like B-25s and B-26s. Once more of the latter were in Theater, and later B-24s and B-29s, then yep, I agree, the Ki-43 was way behind in firepower (and I think the Japanese realized that and started rushing to put more guns on their later model fighters, but always half a step behind / too late).
Early B-25s and A-20s weren't so well defended though. The early B-25s which remained in use I think into 1943 (?) didn't even have tail guns.
You do if you run more manifold pressure. And you'd do that because you CAN with higher-grade fuel.it's not so that work, if take a fiat A.74 engine and i use 150 octane fuel i don't get more power
That assumes at least two things.You do if you run more manifold pressure. And you'd do that because you CAN with higher-grade fuel.
The Ki-43 may not have been crap but it was rather limited.Yep that is the thing i keep noticing in the operational histories. P-51A and A-36 seemed to be pretty much owned by Ki-43, even on the basis of claims vs. losses. Which (to me) emphasizes the notion that speed does not always trump 'maneuverability', and that the Ki-43 was a pretty advanced design.
One of the reasons for the efficiency was that, as I recall, the Japanese copied the Italian 12.7 mm ammunition, that is, they had efficient incendiary, HE and AP ammo
Biggest problem that A-36 and P-51s had in the CBI was they were flying over the Hump (Himalayas). The Ki-43 wasn't a high altitude fighter, but it did better over the Hump with the two speed Sakae engines vs the single speed single stage Allisons. The P-51B/D with the two stage Merlins would've been better over the Hump. Of course, that's from the Wikipedia article cited previously, so that may be a case of mileage may vary.

We have a mediocre fighter shooting down fighter bombers?
What were the positions and speeds of the planes?
Like were the Ki-43s bouncing the P-51A and A-36s from above just before a bomb run or just after?
The old trope about fighter bombers being able to defend themselves needs looking at. They can, if they see the enemy fighters soon enough and jettison the bombs and have time to accelerate to combat speed. Or bounced on return flight.

1st is ball, Aluminum filler in front of lead core
2nd is API, incendiary is the white stuff a head of the AP core
3rd is APIT, A bit of incendiary in the nose, a light weight AP core, and tracer in the back.
4th is the HEIT. the sizable fuse in the front. a bit of HE/incendiary in the middle and bit of tracer in the back.
There were other versions. It sometimes appears they were trying to be too clever.

In this chart the weight of the shell is the weight of the projectile. About 33-37 grams. also note the weight of the propellent.
US .50 cal bullets were 41-46 grams and and the propellent weight was about 240 grains.
HE content of these 'shells' might be 0.8 to 1.2 grams.
Japanese 20mm type 99 HE shell held 10 grams.
One thing we have to look at is the sortie loss rate; for example how many sorties were flown by the B-24s and the Oscars to produce the resulting kill/loss figures? Was the B-24 loss rate higher than the non-combat operational loss rate?Hello Wild Bill
I recommend Osprey's B-24 Liberator vs Ki-43 Oscar China and Burma 1943 by Young, Duel 41. I think it's a good booklet. According to it, in 1943 the Ki-43s shot down 31 B-24s, losing 29 a/c themselves, these are real losses, not claims. I was surprised at how effective the Oscars were against heavy bombers. The Japanese developed a working tactic that took into account the weak armament, i.e. repeated head-on attacks. One of the reasons for the efficiency was that, as I recall, the Japanese copied the Italian 12.7 mm ammunition, that is, they had efficient incendiary, HE and AP ammo
The A6M vs F4U numbers are from this Osprey book here:Ah, my bad, that's what I get for reading a Wikipedia article... I'm gonna put my glasses back on and double check William Green.

One thing about the Ki-43 in particular that differentiates it from the Zero is that it did not have the control problems when diving. So diving away as an escape was not as reliable of a tactic for Allied pilots (this was exascerbated by the fact that they had trouble distinguishing A6M from Ki-43 so they didn't always know what they were up against).
The Osprey books on the Oscar get into actual losses on both sides? That's kind of new and welcome. I may need to pick those up.
Do those Osprey books give the actual numbers on P-40 vs Ki-43? Hurricane? F4F?
Very interesting. Where do you get the hard numbers from that on?
And it flies directly in the face of the P47 being less vulnerable because it's powered by a radial, or the Spitfire and Hurricane having weak armament in the BoB.And regarding Ki-43 and A6M performance, two recent Osprey books in the Duel series say that P-47 vs Ki-43 in New Guinea was 19 kills to 10 losses. Even if losing almost 2 Ki-43 for every P-47, that in itself i find amazing that the Ki-43 can do so well against the huge brute that was the P-47.

Ditto for other opposing Allied aircraft.
I gave a very quick browsing to Molesworth's P-40 Warhack vs Ki-43 Oscar China 1944-45 (Duel 8, 2008) seems to have several long quotes from USAAF After Action Reports and gives claims and real losses, at least at least from the few combats I glanced at but no tables on real losses, only Aces lists and those of Japanese aces gives only Total scores, the USAAF table gives both Ki-43 kills and Total scores but no tables on real scores or losses in air-combats....I think there's another one Ki-43 vs P-40 in late war China theater, but can't remember now if it's any good and if it contains interesting numbers/statistics. The quality of these Osprey books varies widely, some are really good, some are useless...
The A6M vs F4U numbers are from this Osprey book here:
F4U Corsair versus A6M Zero-sen
The aerial clashes between the iconic Corsair and Zero-sen translated into a contest of speed and altitude for the former, versus the latter's outstanding agili…ospreypublishing.com

I haven't seen any Ki-43 vs Hurricane or F4F titles, BUT theres another Osprey book on Ki-43 aces, that is quite interesting, covering the whole war. Also one on Ki-44 aces too, that is very interesting as well. The Shoki was a very tough opponent over China, iirc the gist being it had amazing climb and dive performance (according to US pilots). Pretty sure they thrashed some P-51As too iirc, like the Ki-43 example earlier.
PS: Having seen the figures for F4U vs A6M, it would be so interesting to see some well researched data on the real ratio of F6F vs A6M. Imo he 19 to 1 overall is just hype, i would halve that (and the overall for the F4U, claimed to be 11 to 1 or whatever), and probably halve it again vs Zeros, maybe even lower. Still a massive advatage for the F6F at 3, 4 or 5 to 1, but nowhere near what it is claimed.

P-51s weer based in China and Burma they didn't fly combat missions over the hump.Thing is P-40s flying in the same area, with pretty much* the same engines, didn't have this problem. Also I think some of the P-51A were operated from China. In fact contrary to what the Wiki says I don't remember that flying over the Hump had anything to do with these particular missions. It was a relatively small sample though, probably half a dozen missions before they decided to use the P-51A for other things.
P-40E and K did, the M and N had the higher critical altitude which probably helped.
I used Bloody Shambles V3 to look at Hurricane vs Ki43 combats some years back, and if all one does is make a tally of the kill/loss ratio between them, then it doesn't look that good for the Hurricane. When you look at the number of sorties flown vs the number of kills, you realize that the number of Hurricanes lost to KI-43s was so small (a very low sortie loss rate) and over such a long time frame that it wasn't really an issue for the Hurricanes, which were typically flying low altitude strike missions, and were constantly at a disadvantage in terms of situational awareness and altitude. I expect that the same was true for the B-24s.I read the booklet 11 years ago and it does not have nice table on sorties/aborts/operational losses, But the formations were small, weather sometimes poor . I do not have time to re-read it. A quick look only revealed that there are a couple of diagrams of the formations used by the Liberators, the evasive maneuvers used by the 7th BG's 6 to 7 bomber formation is described, as well as a diagram of the head-on attack used by the Japanese. And from the loss table one can see that either the 7th or the 308th BG were involved in all air battles, i.e. they did not work together.
