(C.1) Spoilage

Bases whose combined airfield and port levels amount to less than 9 can suffer spoilage of their supply (and fuel) stockpile.

Spoilage will occur if the following base thresholds are exceeded:

•Size 8 – above 197k supply (129k fuel)
•Size 7 – above 152k supply (99k fuel)
•Size 6 – above 113k supply (73k fuel)
•Size 5 – above 80k supply (51k fuel)
•Size 4 – above 53k supply (33k fuel)
•Size 3 – above 32k supply (19k fuel)
•Size 2 – above 17k supply (9k fuel)
•Size 1 – above 8k supply (3k fuel)

Note that the check for spoilage is made for each stockpile. A Size 8 base with 154k supply plus 83k fuel will not suffer spoilage. It will suffer supply spoilage if it has 204k supply plus 22k fuel.

Dot bases can store up to 5k supplies and 1k fuel before suffering spoilage.

Not sure If I got it right.

If I have a base size 2 holding 27,000 supplies and zero fuel, I suffer no supply spoilage at the base? And if the same base holds 27,000 fuel and zero supplies, I suffer no fuel spoilage?

The thresholds are individual: one for supply and one for fuel. In your example of a combined size 2 base, exceed 27k supply and there is a penalty on the supply. Exceed 9k fuel and there is a penalty on the fuel.

[Yaab]

Yep, I misread the base list. Alfred gave the example of base size 8 with 154k supply plus 83k, while I was looking at base size 7 storage limits.

If I set two adjacent bases with ports i.e Lae and Salamua to stockpile supply, will this setting override the section 9.3.3.3 AUTOMATIC TRANSFER OF BULK CARGO BETWEEN ADJACENT PORTS of the manual?

In a supply-scarce environment such as China, the idea of bases hoarding three times the required supplies seems excessive. I can park a corps with a monthly upkeep of 1500 supply points in a non-base hex next to Changsha for the total monthly cost of 1500 supply points, or I can park the same corps in Changsha for the monthly cost of 1500 supply points + 3000 additional supply points tied to Changsha. Since bases can only export surplus supply above x 3 requirement, then it is very hard to justify parking Chinese corps in bases, because very little supply is exported from bases to units in field.

It would be much better if bases only collected twice the supplies required instead of thrice.

I realized this years ago and mentioned it in an AAR of mine, but no discussion ever developed further. The 3x supply at bases contributes to China being almost indefensible as you can't get the supply forward if garrisons are hoarding all the supply. I keep my rear Chinese bases almost empty of troops, but still defend against paratroops.

Not so. The problem is that supply flows out of bases to units in the field as a priority, even if the units at the base are starving. Many times I have had to swap starving troops out of a Chinese base with troops in supply in the adjacent hex.

There is another factor. Units outside a base may receive supply from any base within supply range (and in accord with the game's supply algorithm), but units inside a base may only receive supply from THAT base and no other.

This is one of those threads that needs no explanation for being bumped every now and then... anyone who hasn't read the OP should do so and bookmark it for future reference.

More could be said about how supply is expended. Also, what is relevant to stock is greatly altered in DBB-C, which I believe ought to be the stock form. Let me try a list:
In the field, fortifying, repairing/expanding airfields, repairing/expanding ports, and repairing refineries/oil fields can soak up a lot of supply.
Repairing/expanding industry, both heavy and light can eat up a lot.
Industry includes aircraft/engine factories, both repair and production.
Many, many procedures cannot occur if there are not adequate supplies present. For instance, replacements will arrive quicker at well supplied units.
In DBB-C overstack consumes an incredible amount of supply, in both, fortifying to level 7-9 uses a very large amount of supply.
Attacking as well as defending eat up supply.
Creating torpedo inventories expend supply, as well as bombing campaigns and the like.
Bombardments, especially by the likes of BBs and CAs consume supplies.

I've just spent 5 minutes on this, much more can be said.

Alfred, what about command HQs?

They attract 20k supplies to themselves at all times.

Consider. Jap player puts a command HQ in northern Burma in a non-base hex. There are Jap LCUs in adjacent non-base hexes. Can they draw supplies from the command HQ supply stash or do they have to be in the same hex with the HQ in order do get the supplies?

Basically, is command HQ a kind of movable base which can distribute supplies further to LCUs in absence of any elligible base?

Interesting question ...

Did you edit your post? There seems tom be more verbiage in there.

Was wondering the same. I don't think so to be honest, but I has only very random examples from the Chinese front with command HQs.

I do believe, though, that's very beneficial to put a command HQ in a forward Burmese base. I have no clear calculations for that, but consistent and constant results from the practice over the course of years.

Now that was some valuable info for a newbie.
Well worth to bump it after last post a looong Covid year ago.

IME, HQs do not donate their own supply to sub units or any units. When a stack of units gets isolated the combat units run out of supply first because of the higher usage rate and the HQs continue to hold their supply permanently. HQs help draw supply into the hex, but don't necessarily keep it in their own inventory. AFAIK they only keep their own allotment.

I do believe that the HQs only draw the extra supplies to the base that they are at, not out in the boonies.

Something I've noticed in a surrounded stack as Japan in 1945: When supplies are low the HQ units suck them all up and my infantry and arty units are left out to dry...

I'm thinking the next time I need to do a last stand, I'll try to leave no more than two HQ units (a Corps and Army) in the stack.
