I think 12 x 30 for Ki-83 is too many. I only used like 4/5 x 30 and got it in early 45. If you do 8 x 30 you'll have it in 44 for sure.
You have to think about what you're making in the end too. I don't think you can plan for making 12 x 30 (or 360/month of Ki-83). That's also a massive investment in engines, with 720/month of Ha-43 just for this plane!! [X(] The N1K5 and the A7M also use the Ha-43, so you're basically going to screw yourself making that many of these engines. I'm only making 850/month for all of them right now.
Eric,
I tend to not build as many early and mid-model planes as most. And I tend to save my supply/Hi to build final models in very high qty, all based upon my analytic view point that the IJ has finite quantity of both and what do I want to build with it. So I make a lot of inconvenience for myself within the game in '42 … I run razor thin pools until the first of my RnD projects bear fruit.
In the above scenario, '42 is going to be A6M and Nates until Tojo arrives in Sept. Yeah, I suffer with Nates because the early Oscar other than range is just not a lot better than Nate. Nate is CAP, A6M escort/sweep. Tojo replaces Nate in CAP role. '42 fighter build rate is ~ 10/day. N1K replace A6M is escort/sweep role. N1K is first model to build in high volume, but still not that high ~400/month. Ki-84 comes and that is high volume and can work all roles as can N1K. . It is also will run at ~400/month. So, end of '43 I am building ~25 fighters/day.
A7M improves things significantly as does Ki-83. End of '44 I plan to build at least 40 fighters/day. And yes, this is where the Ki-83 being twin engine can hit a speed bump in my planning and I go with the Ki-94 instead. The supply cost on the engines and the HI burn on the aircraft, the Ki94 can start to look pretty good even with those lousy cannons on it (4xHo-5 20mm would be so good!!! Ditto the J7W ...)
Anyway, so I give up a lot of comfort in 42/43 to allow myself luxury in 44/45. A conscious trade-off.
PS: thank you for confirming (along with Loka) that my arrival dates are in fact conservative estimates. I did a game with 18x30 on A7M a couple of times … the arrival date is opsec but it was a total game changer.
PPS: And for those who cry 'fantasy', they should remember that the A7M first test flight was 9/42 IIRC. The model was actually ready to fly 3/42 but the engines delays were the issue; specifically the 2 stage induction. If not for NIH, they could/should have had that up and running late '42 at latest, but …. a lot of allied lives were saved because they did not.
