LOL - they didn't! It's as simple as that.
 

Rich, I enjoy reading what you write. But could you please use paragraphs some? The above needs them badly - it's just hard to read.

I disagree that the 109E turned just as well as the Zero. It turned about equally to the Spitfire, and we know the Zero substantially out turned the Spitfire.

The Japanese could not build the BMW radials, they didn't have the industrial tech for it, so that may explain why they didn't build their own. Without importing German casting technology it was kinda pointless.

Fw-190?

Well, I think Japanese had technology to produce superior fighters to their rivals.

No they did not. They could not produce sufficiently powerful engines, and without that the rest is mute.

Chiron said:
Just look at the Nakajima Ki-84 Hayate, which was proven by US as superior to P-38 and even P-51.

First that plane was not proven superior, only that it was competitive. Also, that plane had a US fuel system and other components in it and was running US hi-test fuel. The info you are refering to invariably comes down to the following quote:


It should be noted that the Middletown test data is virtually unavailable, only rumors of pilot comments about the plane exist. Also, the speed figures at 20,000 feet represent unrealisic performance for that plane since the Japanese did not posess the refinery technology to produce 150 grade fuel, and had problems with their own engine design (especially the fuel system). And finally, the speeds for the P-51 and P-47 reflect Normal (or Military) power performance. At 20,000 feet at full WEP both the P-51D and the P-47D could manage about 420 mph, a difference of only 7 mph off the claimed Middletown Frank data - and that is for a normal service plane, a tweaked plane (as the Frank was tweaked) could of course have gone faster.

Chiron said:
By that, Nakajima Ki-84 Hayate can surely be the plane that can beat any plane from Axis or Allies, Fw-190, Spitfire.....

Well, it's entirely speculation. Actual performance of the plane in combat was not that good. P-47N's and Corsair's ate Franks for lunch!

A system which failed badly at a certain altitude. Had the 190A's not have had the Kommandogerat on them they would have been effective up to at least 30,000 feet. The thing relied on the difference between internal and external pressure, and when external pressure dropped to low, it effectively got a "divide by zero" error and fell into "safe mode". I'm not sure if this was fixed by the Dora9's entry into the war, or if it maybe had a bypass feature, but this was a serious problem for the 190A's.

Also, a decent pilot can adjust manifold pressure and throttle easily, mixture needs little messing with for combat settings, the pitch control was automatic, and the cooling flaps on US planes were automatic (with manual override). Controlling these things became second nature for a well trained pilot and US evaluations of the FW's unified control system concluded that a well trained pilot could extract more performance from his plane than such an automatic system would provide.

It was (of course) an analog system, not a digital one as FADEC.

Attached is the NACA report on the Kommandogerat if you're interested.

That "It's a Frank, forget it!" comment has to do with scrambling fighters to intercept one going horizontally at altitude just in the reach of the radar, something that the Frank pilot's did frequently. It was impossible to launch fighters which would have to climb and travel 50-100 miles to make that intercept. When P-51's, P-47's, or F4U's were already in the air and in the area, they did intercept the Franks.

I agree the Frank was the best Japanese fighter of WWII, but lets not be over-rating it. It was a 410 mph (best case) fighter with fuel system problems. It was facing the 450 mph P-51, 440 mph P-47D, 465 mph P-47N, and 455 mph F4U-4.

P-47N's ate Franks piloted by the most experianced Sentia remaining to Japan for lunch over Korea!

How did the George have any advantage over the F4U-4? It was a good match for the Hellcat, but it was outclassed by the Corsair, P-47, and P-51 in most repects - most notably speed.

And its guns were powerful, but also of relatively low RoF. The Ki-84-Ib's guns (4 x Ho-5 20 mm's) were probably superior for fighter vs. fighter combat.

As covered in one of my posts in this thread the 109 would not have been a very good carrier aircraft. The Bf-109T which you are referring to was the carrier version made for the Graf Zeppelin and it basically was a Bf-109E with lenghtend wingspan and wings that folded, and an arrestor hook. Nothing was changed to the landing gear which would have made landing on a moving carrier even more dangerous.

Said in the reference you presented RG:

The Hayate was fully the equal of even the most advanced Allied fighters which opposed it, and was often their superior in many important respects

And there's a very obvious reason for that ! The pilots of the Franks were extreemly inferior in training !
 
Ki-84:

The North American P-51D Mustang and the Republic P-47D Thunderbolt were both left behind, the first with 3 Mph (5 km/h), the second with 22 Mph (35 km/h).

3 mph not that much of a difference!

Ki-84
Strengths:


Good performance
Good protection
Good armament
Good maneuverability

Weaknesses:


Problems with fuel pressure and hydraulic systems
Weak landing gear struts

Problems with fuel pressure and hydraulic systems

Big problem!
 

That is flat wrong. The Ki-84 pilots were the best the Japanese had. The IJAAF 22nd and 85th Sentais were vetran units. The 85th Sentai was formed in March 1941 and claimed a 4:1 kill ratio. The 22nd Sentai was formed in March 1944 out of vetran pilots and was the first to recieve the Frank, and they fought in the Philippines, China, and over Japan.

In general, only vetran pilots recieved Franks. The IJAAF was no where near so talent depleted as the IJN. The argument that the the Ki-84 was flown by rookie pilots simply does not wash!

Those speeds are at Normal or Military Power. At WEP the P-51D was capable of about 445 mph @ 26,500 pulling 67" of manifold pressure feet and the P-47D was capable of 441 mph @ 27,700 feet pulling 64" of manifold pressure. Both planes could pull more manifold pressure with 150 octane fuel, especially the P-47.

"US pilots who flew in both theaters consistantly reported that the Japanese were the more dangerous foe."

Holy!

I guess Saburo Sakai was right about superiority of Japanese pilots as individual. But, I never thought that Japanese pilots were EVEN dangeous than their German counterparts!!!
 
Keep in mind that most theater transfers were from the PTO to the ETO, so they would have faced the best of the Japanese pilots and not enjoyed a superiority of aircraft. Going to the ETO after a significant break they'd have entered that theater when the US was gaining parity or even advantage.
 

If you read my full post, I said that it was not a relevent difference.
 
Well, I think if you look at the real wartime performance of the Ki-84 the speed advantage lies with the US planes by at least 30 mph. And also the peak speed is not so important, the Ki-84 would not have been able to sustain those speeds nearly as long as the enemy planes.
