The question about what synthetic plant techs does have been answered

[Denkt]

You can only have 1 plant per state, the other techs increases that limit by 1.

And as a bonus I can tell you that a synthetic plant now produce 5 oil and 2 rubber (old values was 2 oil and 1 rubber)

Well I'm glad they made them viable finally.
At least in this mode you have the trade off of two civilian factories traded away for 8 resources vs one synthetic plant for 7. Still makes civilian factories at a similar IC cost better if you can trade, but at least in a game play balance sense the synthetic plants are viable as you only take one slot so you can eventually make up the difference over time by the density advantage.

So you can produce max 10 oil and 4 rubber per state ? Seems good enough for me, it could be a good help for Germany but not enough so they still have to worry with Ploesti and Caucasus oil-field.

You can build up to 5 synthetic plants per state as long as you unlocked all 5 levels in the research tree, just as with radar aswell (radar is built on an state level tho!), which has 5 levels to research aswell. That means if you research all levels and have the slots availabel for them you could produce 25 oil and 10 rubber in an state.

That is of course nothing compared to the rubber and oil reserves in Singapore and the caucasus. Granted that you most likely have to ship them via convoys to your homeland in some cases, which can require quiet alot of convoys and protection for them.

Here is an screenshot from the resources in Singapore alone. 413 convoys is an impressive amount, that the UK has to protect all the way to mainland UK in order to be able to use those resources.

Here is another one from the dutch east indies region aswell.

Atleast at the moment, numbers are of course still not final, 1 factory equals 10 resources.

Yeah, synthetic will not beat natural sources in HOI4 but if it is your only way to get access to oil and rubber you will probably have to use it.

I may have missed it, but synthetic plants are civilian, right? So they do not use input resources? (Unlike synthetic oil in Vic2, which requires constant coal inputs)

There is no coal as an strategic resource in the game, no. They simply generate an constant stream of oil and rubber without any input required. They are quiet expensive and take up factory slots.

No, it is now 10 Resources for one civilian factorie

 

[Commissar Yossarian]

I missed that, so you're completely right.

Still an utter waste. I'm most disappointed.

Does radar or forts use factory slots? I am under the impression they have their own slots, the same as shipbuilding factories do.

You are right, radar and forts (bottom left in the picture) won't use a factory slot, BUT dockyards will.

Civilian/Military factories, dockyards, synthetic oil factories, rocket test grounds and Atomic reactors need a free factory slot in a province.

Actually they dont, but you have to unlock additional levels of radar via technology, that is actually what i meant. Sorry.

For those who dont know:

• On the right side, the top group of buildings is on an state level, of which you can build an set limit (10 for everything, except radar which has up to 5 slots).
• Below that are the buildings that use up factory slots, where the synthetic oil plant has additional levels to research, which allow +1 each in one state. Level 1 = 1 per state etc.
• The third group is built on an provincial level and again, limited to a certain amount (10) per province.
• The last one is to convert civilian to military and military to civilian factories.
