Hi Chaps,
sorry about the delay – but RL(tm) had a say ..
Japanese production, or rather resource and asset management in the early stages. That is resources, oil, HI, specific production factories etc. Just my take. I know, there is some kind of „Zen“ behind all that, but I rather use a kind of pragmatical approach.
There are two components influencing Japanese asset management: First: Beyond a period of four to eight months (depending on Japanese behaviour o the allied player skill), as much of the available resources (oil/resources) need to be secured as possible. Chiefly in the DEI and Indochina, and for the icing on the cake Malaya, China and PI.
But. As a Japanese player on Dec 7th you do not know, how well or how long your oppenent will succeed in keeping you away from your „honey-pots“. Nor do you know about the actual shape of the resource centers after being taken. ( I know, there are some theories about enemy „engineers“ present and a bases shape after taking, but the good old dice still have a very strong impact).
Second: How long do you expect the „war“ - or PBM rather – to last ? Are you going for a „shock and awe“ approach, or are you looking at a rather long war of attrition ? (Omiting the in betweens)
As a Japanese player, opting for the „diplomatic“ solution – i.e. an early „withdrawal“ of your allied opponent - is a valid expectation. And this is quite often based on some stunning tactical issue, rather than long term strategy. Something like sinking all available allied carriers in a single engagement.
Anyway. I am basing my Japanese planning on „expectations“ with a rather large margin for my oppenents skill, or luck and the „dice“.
Supporting the forces in the field with supplies, equipment and upgrades comes first, base development comes second and after that strategic issues and long term projections.
To sort these things out, I tend to use a 3 Months, 6 Months and 1 Year planning perspective.
In other words: Conserve as much in the way of resources, supplies, HI-points etc. as possible (to be able to stay in the game in situations of adversity as long as possible), while trying to improve the striking power of your forces at the same time, to gain your „war aims“.
Short term:
Early on, Japan is in need two things: Modern fighters (Zero/Oscar) and „armaments“ to support the ground forces (or ground force replacements).
A „Zero“ production level of 120 to 140 per month and the same for Oscars at the end on 1/42 should be the goal. (Waiting for Nates to convert early in 1/42 saves a lot of supplies).
An armaments level of 600-800 should be aimed at.
A slight increase in AFVs will do.
Mid term:
„Sallys“ are a sore point. Even though, by the numbers „Helens“ are not much of an improvement, the op-losses of „Sally“ units are very high. Expanding „Helen“ production early – while waiting for „Sally“ factories to convert in 1/42 is a sound option. Some 60-80 „Helen“ production is the aim for the first 6 months.
Transports:
As for transports, the IJN has the best or most versatile, but the number of IJN pilots is the issue here. Unless the transports have special capabilities (range and supplying bases without airfield), none of the IJN transport groups is worth keeping except Tinas (Range) and H6KL-2 Mavisses (supply for bases without or with havy damaged air field and range). Of course IJN Tabbies have a good range/load relation, but they do not have any armament. Sending them into contested air-space is a bad idea indeed.
For most purposes, IJA „Topsies“ are quite as suitable. For the first 3 months, I tend to stop all transport production, except for about 20 Tinas and some 20 Mavisses – to flesh out existing air units and slowly convert IJN transports – while keeping the „Tabby“ units on the ground as far as possible.
Floatplanes:
There are only two usefull ones: Jakes and Glens. The others lack the range, are very vulnerable to fighters or have no purpose anyway. Replacing shipboard FPs to Jakes – esp. in those TFs heading for contested airspace is very important. Other Jake conversions have no high priority. I stop all FP production – except Jakes with a slight step up to around 40 and leave the Glens.
Patrol Planes:
Converting Mavisses to Emilys is a good thing. Having some 30 Emily production in 1/42 should suffice to have the conversion done by mid 42.
Dive Bombers:
Idas are useless. After the first „ship hunting days“, I convert them.
Anns and Marys are quite good aircraft – used as attack bombers, ship hunters and ASW patrols on small fields. I leave at least one unit of each unconverted, to hang on to the replacement caches, in case I want to convert some Sonias to Lillies later on.
Recon:
Nothing to do, til the new Dinahs arrive.
Vals and Kates:
A very small increase to each in 1/42 should do. to build up a cache of 100 each – unless you run into heavy carrier actions.
R&D
I stop all R&D for types not available within six months. There are quite a few innitial R&D allocations for types available later on, which will not be needed to spawn new air groups outside the „auto conversion“ upgrade tree. These factories are my first choice for reallocation into currently available AC. Useless floatplane and transport factories come next. I rather use a number of small factories to increase production levels than a smaller number of big ones. It makes things more incremental and converting a small factory to a badly needed type is less expensive. Plus: Expanding a few small factories will yield results sooner than upgrading one or two.
Engines:
I keep Mitsubishi, Nakajima, Kawasaki, Aichi, Nissan and Toyoda factories. Stopping two large Mitsubishi (at least 160 production) factories and converting the Hitachis to Nakajimas should do early on. Monitoring the engine levels quite closely is essential.
Heavy Industry
I leave it alone for about three months. In the first phase it is much more effective to keep the HI outside Japan supplied (Formosa, Hanoi, Hong Kong, Singapore etc.) than starting an expansion programme in order to maintain the HI point cache.
Other:
For the time being, all ship building or repair yards are left as is. The ports at Okayama and Maizuro will be expanded as the airfield at Tsu. At least two bases in the eastern Kuriles are recieving upgrades as do the airfields at Bangkog, Kwajalein and Palau and the port at Truk.
Fortifications in Hanoi and the frontline Chinese bases have a high priority.
If nothing else, the Japanese player needs to balance the many upgrade options against the political points (PP) available. Since most of the candidates for upgrades are in restricted commands.
Therefore, PPs are the next issue.
Cheers !
