Engines:
Ha-31: 45(0) - no change here. Pool of 245 and need is 40.
Ha-32: 60(40) + 0(40) - Need is 140 with a pool of 45.
Ha-33: 65(60) + 0(60) - Need is 179 with a pool of 116.
Ha-34: 10(0) - No need until 4/42 when the Helen come online. This factory is at Maebashi, where there is no supply currently. When that is fixed, I'll increase the factory to 160 for the 80 Helens. The pool is currently 3.
Ha-35: 180(50) + 0(50) + 0(50) - Need is 318 with a pool of 166. Hopefully, the factories will repair fast enough to keep some in the pool.
Other notes:
The Glen uses the Hitachi Amakaze which is not in production. The pool is 122 and will be expended on Glens over the next 6 months or so.
The Topsy I uses the Ha-5, which is not in production. The pool of 101 will be partly or fully expended on Topsy Is. I haven't decided whether or not to use up the engines or upgrade. We'll see.
The Kate N1 uses the Nakajima Hikari, which is not in production. The pool of 99 will be expended on Kate N1s.
Don't forget that the Tojo uses the Ha-34. You will need a LOT of 34's by Q3Y42.
I tend to put additional engine factories to the 32 and 33 to allow faster ramp of my a/c factories. But then I also tend to run pretty tight supply the first 3 months of the war. Maybe too tight? I think I'll go back to my analyses and move my supply margin up a bit based upon what you're doing here.
What daily supply rate do you allow for combat operation support? I use 10K/day until Feb42 at which point I generally have no further problems ...
