well, this is a more difficult question than it appears, and one has to make assumptions as to the intent of the question. I assume that the aircraft to be selected must at least have reached protype stage, or at the very minimum have reached a stage in development where production was at least a possibility. If all projected types are included, the excercise ceases to have any link to reality.

So I am going to assume that the aircraft not only needs to be a design, it has to have reached some stage of production or have reached a stage of design where production was feasible.

The second comlication is the time period of the designs.....how is a pre-war P-50 Polish Jastrab able to be compared with a a CAC-15, designed and flown in 1945. I think therefore that the best that can be done is to make some allowance for the time at which the aircraft was designed.

Then lastly we need to consider those countries that took a design, and modified it. This might need to be clarified, but i would assume the mods would need to substantially alter the nature of the aircraft. I dont consider, for example the Spanish version of the Me109, as an indigenous design, it was not sufficiently altered to earn that. On the other hand, the Hungarian mods to the Re2000 I do consider to be a separate type, partly because of the circumstances surrounding its development, and also because those changes were quite substantial and took what was essentially a failed design and made it a success

So, having established some criteria , what is my list. Here are a few suggestions

Poland: P-50 Jastrab (1939), Pzl P-62 (1940)
Latvia: VEF I-19 (1940)
Denmark: D-21 (with 20mm cannon)(1940)
Holland: D-21 (1938), Fokker GI (1939), Fokker FK-58 (1940)
Belgium: Renard R-37 (1941)
Rumania: IAR 80 (1941), IAR 81 (1942)
Hungary: Heja (1941), Me210 (1942)
Yugoslavia: IK-3 (1940), IK-5 (1942???)
Switzerland: D3802 (1945-6)
Sweden: J-22(1943-4)
Australia: CAC Ca12 (1942, Ca14 (1943), Ca15 (1944-5)

I stick with my J22, how many of the others could out climb the P-51D below 15.000 feet and operate from the same harsh conditions?

With 575 km/h (360 mph) from a 795 kW (1,065 hp) engine, it was in the same class as the early marks of Supermarine Spitfire and Zero....
