I see everyone is talking about supply for Japan in late war and I thought I'd take a quick look at my own situation (Currently at work so I don't have Tracker access). Currently its May 16, 42. According to the Intelligence screen I have 3,780,857 supply in my empire - plus if I'm reading this correctly I have roughly 200k on ships. I did a quick check on the supply hog - Tokyo - and there is 1,878,024 supply sitting there. I know Kagoshima and Nagasaki have roughly 40k each - I load supply from there to send out. So I am guessing I have 2m+ supply sitting in the Home Islands. Not sure if that is good or bad ?
I am also concerned with the upcoming supply costs to convert the next wave of aircraft. below is a list of my current Aircraft and Engine factories. Please comment on my setups...
A6M2 Zero: 2 factories each of size 60
A6M2-N Rufe: 1 factory of size 30
B5N2 Kate: 1 factory size 60
C5M2 Babs: 1 factory size 30
D3A1 Val: 1 factory size 60
E13A1 Jake: 1 factory size 30
E14Y1 Glen: 1 factory size 20
G3M2 Nell: 1 factory size 60
G4M1 Betty: 1 factory size 60
H6K4 Mavis: 1 factory size 30
Ki-15-II Babs: 1 factory size 30
Ki-21-IIa Sally: 2 factories size 30 & 60
Ki-30 Ann: 1 factory size 30
Ki-43-Ic Oscar: 2 factories size 90 & 30
L3Y2 Tina: 1 factory size 30
MC-21 Sally: 1 factory size 30
(several other 'leftover' factories of various sizes and various aircraft not currently used)
Engines:
Mitsubishi Ha-31: 1 factory size 30
Mitsubishi Ha-32: 4 factories size 60, 60, 90, 90
Mitsubishi Ha-33: 4 factories size 90 each
Nakajima Ha-34: 2 factories size 60, 90
Nakajima Ha-35: 2 factories size 150, 210
Nakajima Ha05: 2 factories size 30, 60
To me, a lot of the aircraft requirements depends on how aggressive you and your opponent are in the air. For the Val and Kate, I use them on KB (obviously) but all of the land based DB & TB units are for training exclusively. I find that 30-40 are sufficient and still are shut off most of the time.
Zero and Rufe are good. My A6M2 was at 100 as opposed to your 120, but should be fine.
C5M2 seems high at 30. You really don't get many chutai and your losses should be minor. Keeping 6-8 in the pool is fine.
Jake is fine for me at 30. But, I use Petes in training and the Daves and Alfs along with the Jakes operationally (Daves for ASW due to their short range). If you want to use the Jake exclusively for operations, you will probably need more, especially if you increase the size of your smaller FP units.
Glen is fine. I had mine set to somewhere around 15-20 and built out the engine pool. I had 126 Glens in the pool and then changed the factory to something else. I should have plenty for the war. To date (Nov 42) I've only used 2.
I set my Nell and Betty factories to 30 each. I'm very cautious using those units. Their mission is anti-ship 95% (or more) of the time. I keep ~100 of each in the pools and have have very few losses to date. They will start taking significant losses when my opponent goes on the offensive but until then, life is good for these pilots.
Mavis/Emily production seems high at 30. They are expensive to build at 144 HI apiece. Mine is set at 15 and I have plenty. I've since upgraded to the Emily because it's superior to the Mavis but still use the Mavis where the extra range of the Emily isn't needed.
Ki-15-II - Why are you building this? I would put my resources into the Ki-46-II (and later the III). Granted the Dinah costs twice as much, but the extra range is nice and losses are relatively minor.
Sally - 90 seems kind of high unless you don't plan on building the Helen. If you aren't building the Helen, then 90 is too low. I build 40 Sallies and 90 (recently increased to 120) Helens. I can just barely keep up with losses with the 160 total production. It'll drop off as I shift from GrdB to ASW with these guys.
Ann - I wouldn't build any more of these. Eventually you'll want to upgrade the 1E units to 2E (and will have the PPs available to do it easily). In my game, I built a bunch of Marys (engines already available) for ASW duties but haven't really needed them. I won't bother building any IJA 1E bombers next game.
Oscar - that number works well with me.
Tina and Sally transports - I've been fine with 15 of each, especially with the Tina. I used all of the old IJA transports operationally with the exception of the really short ranged one (Theresa?). There were 36 of them and I used them in the 4 transport chutai (9 plane max each) starting the game in Manchuoko for transport pilot training.
Engines - I build engines to meet my airframe requirements. I didn't check but as long as you have engines for the airframes you want to build when it's time to build them, you're good. You have to look to the future though. I usually plan about 6 months in the future for my engine factories to meet my airframe needs.
