IJ production mistakes

Naval build point either need to be restarted or turn off some ships.

Beginning of 43.  I am making some changes IJAAF ftr production.  With 4 times more army fighter sqns than IJNAF sqn's in training I had about 6 uncommitted factories producing marginal planes that I can convert.  Had to decide to go for the ki84/100 or the n1k1j/a7m2. 
Decided the following:
ki931a- save for later
93b-change to ki84a
ki94II-increase to 30--cool
ki74-change to ki100a
ki67a-change to ki100a
ki67t -change to ki84a
ki84b-change to ki84a

This will give me 4 factories each r/d on the 84/100. when they go active keep one in production then r/d the rest on the next upgrade.
Should have done this 2nd turn but what the hell.

engine changes

I note i am producing 100 frames of ki61a but only 20 ha60 engines.  Currently no ki61 is deployed in the field.  I will shutter frame production for the time being and allow my engine pool to build.

If I'm doing my sums correctly, 1.9M HI @ 900 single engines ac/month => about 1700 days worth of production.  (900 ac/month = 30 ac/day *(18+18) = 1080 HI/day).  Late game you are prolly building mostly single engine ac.  If I back it around the other way, you could build over 3000 single engine ac/month until June 1, 1946 (1,900,000/(18+18)/14 months left in game time).  That's a lot of kami's.  Trust your pilot pool is building up kami pilots. 

Let's do some more math: 12 CV/CVE's out of the war for 1200 ac.  You can do that 3x/month for the next 14 months.  You know, I don't think the allies can survive that kind of attrition.    At this rate, they stall out before they even finish up the PI.

Can't wait to see your updates on how effective they are.

Radar:
Well, I'm going to keep building twin engine a/c as well, and a lot of HI comes off each month for pilot training. Plus, I haven't actually been able to mount any airstrikes until now because all my bases get shut down by 4E bombers before he gets close. This was sort of an error/fluke I think. If he just neutralizes all my a/c before moving in, he might not have to face many if any kamis. But of course, 1200 a/c for 12 CVs of various types is a pretty good trade. I would gladly do that over and over until I had no more a/c left or he had no more ships.

My allied opponent has surrendered in March 43.  This will be my last month of production reporting.  I note my fuel status in Japan is getting into critical status...

Industry: I was updating my version of tracker when DH resigned.

A/C engine production:

A/C production:

This is the plan for the A/C production end game. I listed the sort by amount of research into each plane type.

Because of all the errors I have made learning the IJ production system it is probably best for a newbie to read this thread from back to front.  I want to thank Damian, Major Mike, John3rd, and all others for providing input into this AAR..

BTW, this link will be a better source for IJ production as time goes by.

I Consider the G4M2 a waste of resources. The Frances arrives earlier, it's much faster (340 mph) and it has armour. It lacks the range of the Betty, but for long range missions you already have the G3M3 (Nells) which can go up to 26 hexes and it's more or less as good as the Betty.
Moreover the Frances uses the Ha-45 engine, which is used by most mid-war allied fighters, so you should have enough stockpiled when the R&D industries for the Frances become repaired.
 
I have also concerns about researching the Judy line and the Myojo at the same time. Don't think it's a wise solution. Why invest so much on the Myojo and so little on the D4Y1? The D4Y1 can be researched easily with 4x30 factories and get it by november 42 without much stress. Then you better skip the D4Y2 (which keep on using the Aichi-60 engine) and start R&D the D4Y3 (which, instead, uses the Ha-32 which can be stockpiled up to 500 easily). The latter will be, imho, the key for late war naval engagements. With the engine bonus and enough R&D industries you can hope to have it by second half of 1943. This plane, along with the Jill, will give you the ability to strike from 8 hexes using your CVs...which is basically the only hope of surviving a CV-CV encounter in mid-late war.
 
Same goes for the Grace. This is, imho, a great plane and it should be R&D heavily.
 
 
After having studied the subject for a long time, my overall view is the following:
 
Use the Rufe to R&D the A6M5 and start R&D the A6M3a (think 3 factories for the A6M5 and 2 for the A6M3a with the engine bonus are more than enough). As soon as you get these models, abbandon the whole Zero line and convert these 5 factories to the SAM line.
 
I still think investing any resource in the Shidens or in the Jet-planes is a waste of resources

Off top of my head only 2 planes use the ha34.
Ki44 and the ki49.

select the engine tab in air production, then select ha34.

That's correct:

Ki-44 Tojo
Ki-44-IIa Tojo
Ki-44-IIb Tojo
Ki-44-IIc Tojo
Ki-49-Ia Helen
Ki-49-IIa Helen
Ki-49-IIb Helen
Ki-49-II KAI Helen

Well, most IJ players like the Helen and Tojo.  And they tend to build a LOT of them.  Like everything else in the IJ economy, you need to plan it and then make your moves slow and easy.  Fragile economies don't react nicely to heavy handed techniques.

I agree with Pax. My intent is to increase production of the Ha-34 to 270, to accommodate 90 Tojos and 90 Helens.

I was thinking about the number of total army and navy sqn's active in the field and in rear area training.

12xOscar
2xTojo
all in the field.

14 nate sqn's in training.

So 50% of all army fighter sqns are training.

Navy:
2x a5m4 cluade
4x a6m3b
1x a6m5
All in training 7 total

11x a6m2 carrier active
9x a6m3b field
5x a6m5   field

7 training
25 active

naval air pilot training ratio is 1 sqn training to 4 in the field.  This may be a problem...but carrier air is not as engaged as the field sqn's.

I will look at all catagories of  pilot training when I have time.

It most definitely is a problem. It's not only carrier air, but IJN land based air as well.

There are simply not enough Navy squadrons to dedicate to training... Particularly because you need Zeros and Betties on the frontline. Depending on how bold you are allowed to be with squadron resizing (I personally do resize and convert float fighter units to fighters, when I can, but do not resize units beyond the normal maximum kokutai size of 45), this bottleneck can be partially circumvented, but IJNAF still will be behind IJAAF in pilot reserves.

One alternative is to dedicate some of your floatplane units to training fighter pilots. Not enough to solve the problem but it helps.

+1. They will train for escort. When you switch from FP to fighter your pilots will lose a little EXP and Skill, but .... alternatives aren't so good.

Honestly, i just game the system and resize land based via CV's ... then divide. 2/3 training 1/3 available... This is my bad boy solution. I do the same with FPs.
In my mod however; i have dedicated training units and the need to build trainers.
