You misread what I meant or I said it badly. I was refering to BigPlay's comment that Stoney quoted.
Both Japan and Germany had good engineers who where just as good and dedicated as anybody in the US, UK, or USSR.
But neither of them had superaircraft about to come out that would dominate the Allies. The J7W, for example, while very bold was ordered into production before it had even been flown simply due to the desparation of the Japanese government. In the two test flights it did have there were indications of serious stability issues and it is unlikely that barely trained pilots would have been able to get anything out of it but death. The He162, while an absolutely astounding weapon program even without taking Germany's declining situation in late '44 and early '45 into account, was likewise too much to handle for barely trained pilots.
In game terms I would love to see how the A7M would do if Horikoshi had been allowed to use the 2,200hp Mitsubishi MK9C engine as he wanted instead of being forced to design it to take the Nakajima Homare, as in the N1K. He told the Navy it would not have the desired performance, the Navy insisted on using the less powerful Homare to simplify their supply issues, he designed the A7M1 with the Homare and the Navy rejected it due to poor performance compared to the desired performance. He redesigned it to take the MK9C, but the program was then delayed by an earthquake and US bombing. If he had gotten the go ahead to use the MK9C from the start the US probably would have been facing A7Ms in combat sometime in the last 6 months of 1944.
What I object to is the idea that sites like
Luft46 give uninformed people that Germany or Japan had things that were about to see service that were far in advance of anything the Allies had and that just isn't true.
Had the war in Europe lasted longer with Germany holding its borders the only likely difference is that the Do335, He162 and Ta152 would have seen some heavy usage. The Me263 would probably have gotten into combat too.
For Japan, had the war lasted longer (imagine no nukes) the J7W1 and A7M2 would probably gotten into it. Certainly late designs like the Ki-102 and J2M5 would have seen heavier usage too. Things like their massive bombers capable of reaching the US were simply wish list things that were never going to happen in the wartime situation Japan was in.
Against these things we have Allied aircraft in the wings such as the F7F and F8F which were in service and on the way to the front. We have the Hawker Fury and the De Haviland Hornet and Vampire on the way. Too often when talking about the "almost" made it stuff Germany and/or Japan had people forget about the Allies stuff that also almost made it or was on the way.
