Sure, as the Japanese player you could convert the 300+ Ki84 factory (which is what Mog seems to be talking about) to A6m2s. It will not start at 300 aircraft a month. It will start at 0. It will probably not even start to repair untill after April '42. Sometime in June '43 it will be producing 300 aircraft so don't give me "Japan producing at '44 levels in '42! Eeeekkk!"
Hi, I don't think I am the residient genuis but I can count. I did not have any specific factory in mind. I just know that you are using 2 production systems. The AI does not expand production the R&D is this expansion. Humans expand factories already producing. (and reach the level the AI gets from R&D coming on line) and gets the R&D production when it comes on line.
Converting the Gumma KI-84 Factories on turn 1 results in 236xA6M2. They repair at 1 per day so every month an extra 30 A6m2 will be produced. (Japan can expand engine production by 30 per month to keep up)
End of Dec 41 Japanese A6M2 production would be +23
End of Jan 42 A6M2 production + 54
End of Feb 42 A6M2 production + 82
End of Mar 42 A6m2 production + 113
End of Apr 42 (when you say they will begin to repair) + 144
End of May + 174
End of June +204
End of July +234
No it will be around Aug 42 when factories are fully producing an extra 236 A6M2 per month. (not June 1943) (by the time the factory fully repairs it will have produced an extra 1028xA6M2 by June 1943 it will have produced an extra 3388xA6m2)(thats 125 Daitai worth of A6M2 produced by a factory that should not even exist)
Cost to Japan 30k supply per month. Japan produces 25k per day.
These aircraft would be over and above what Japan could expand using the real factories.
Those numbers are converting 1 factory complex. Without any R&D models become available for production on historic date. If you don't see a problem then I don't see a problem.
Of course that is not how I would use the R&D factories. I would select the aircraft I most desired early production of and change all the R&D factories to researching it.
The normal Japanese player in order to get any aircraft model ealry would need to halt actual production in order to assign factories to R&D.
But the basic problem is simply this. Remove the R&D and have the Japanese player expand aircraft production. As time passess he will produce more aircraft per month and change types to newer models.
The AI will not expand factories so as the R&D comes on line production increases and newer models are introduced.
Human player expanding only the actual factories and AI production will be very close in number of aircraft produced by end of war.
Now take human Japanese player who expands only the existing factories and leaves R&D alone. As the R&D factories come on line his production will get a free increase. Really using the R&D factories there should not be any hard choices for the Japanese player. He builds everything he wants. By the end of the war he is producing all his normal expansion plus the R&D factories (and he can expand these as well)
Using just that Ki-84 factory. One player would need to convert an existing factory to Ki-84 to produce it. The other will on a certain date just begin producing Ki-84 at 300 per month.
He will continue to produce any other types he desires because he has no need to change models at existing factories. Even if you never tamper with the R&D factories by wars end all the aircraft they produce will have been above and beyond what you should have been able to produce.
