Budgeting for a fleet

[kilemall]

Well, construction capabilities are more important than raw cash. Are there rules about how much construction capability a system can have though?
As far as I can see, the best way we have of determining a systems industrial capacity is by its GDP?
Of course population is important as well, but as that informs the GDP it is already taken account of.


When you give a ratio of 1:3 or 1:5, are those small ships scouring the larger directly? Or are they separate, ie detatched patrol groups etc? Also is that radio by number of ships? Or by tonnage?


If there is a way to (easily) determine a systems industrial capacity without just relying on its GDP then I should love to hear it.

Please note I am not just talking about the imperium here - I am thinking in general terms. So i am not concerned by how many starbases have been built on the official map, so much as how much ship building capability could theoretically be built and maintained.

CT TCS had a tonnage calculation, ah here it is.

C=PxGM/1000
where C is capacity in tons, P is population, GM is government modifier (some governments are more warlike overall, some are very low budget during peace and high during war, etc.).

So current Earth at 7 billion people is Balkanized and not at interstellar war. The GM would be per nation, I'm just going to aggregate at .90, that yields us 6.3 million tons of capacity per year.

Budget is
B=Cr500 x GM x P
So using our previous figures, that yields 3.15 trillion credits.

Earth by these rules can build an awesome amount of very vulnerable smaller interplanetary warships.


I think there are caveats saying this doesn't apply to explaining the Imperium's naval finances, but it could usable for your ATU.


I know there is an MgT TCS, don't know if it's the same as this.

Thanks for that, now to figure out how to extend it for multi-system polities.

Well they cover that too, there is a 'local currency conversion' rate table where you cross-index the starport and TL to take that actual tax collected and convert it to the 'coin of the realm'.

So let's say that modern Earth 3.15 trillion credits was going to a TL15 starport A polity. The cross index value for TL8 starport E is .45, so the tax forwarded would be 1.14175 trillion credits.

Going from Earth to a TL7 E planet would be 1.488 trilliion credits. Earth to TL12 A would be .60 or 1.89 trillion credits, etc. It's basically 5% difference for each step difference between starport levels and another 5% per TL difference.


Personally on the tonnage capacity I would double it for an Industrial world and halve it for a Non-Industrial world. Or maybe it's normal on the Industrial world during peacetime and doubles during war.
