Just started, how do I build factories faster?
Trying to build civilian factories and only 1 builds at a time and it takes a very long time to build.
(playing italy)

When I build equipment does this slow down this construction or what?

What do military factories do?

One of the National focus trees has research to give you military factories/infrastructure and civilian factories. Also in the industrial research tab you can research construction that speeds up the time it takes to build factories.

Civilian factories are used when you trade with other nations for oil/steel/rubber etc. Also they are used when constructing factories/infrastructure airbases etc so the more you have not being used for trade the faster your build time is.

Military factories are used to produce equipment like tanks, rifles, planes etc. The more military factories you assign to a specific equipment build the faster it will produce said equipment.

When you build stuff, that's done by Civilian Factories, and up to 15 Civilian Factories can work on a project at once. This means that if you have 13 CivFacts, they'll all work on the project that's highest on your build list. If you have 33 CivFacts, then the first 15 will contribute to the 1st project, the next 15 will contribute to the 2nd project, and the last 3 will contribute to the 3rd project by only at 1/5 speed (3/15=1/5). Once the first project is completed, those Factories "trickle down" through the list, so that the topmost 2 gets 15 each and the last gets the remainder.

Once you hit 45 CivFacts you can work on 3 projects full time, then when you get a 46th you can work on a 4th project 1/15 time.

And yes, as Grief says, look into Industrial Tech. And National Focuses.

I would advise against building civilian factories early game, they're extremely expensive (time-wise) costing 10,800 "factory power" (dunno what the proper term is)

Compare to 3000 for infrastructure (which can also provide you resources now), 1250 for an airbase, or 3375 for radar (once you unlock it)

Each factory outputs 5 "factory power", but keep in mind that it's never actually 5 "factory power" because there are a ton of other factors that immediately boost it - trade law, for example.

Furthermore your focus tree generally has a bunch of factories you can get without focusing your civ factories on it.

So the civ factories are what builds other things like infrastrucure or air bases? Do they also build mil bases/? Are mil bases worth it?

If by military bases you mean military factories, then yes
civilian factories build literally everything in the Constructions screen. They also do repairs if they need to, and work on converting military factories into civilian ones and vice versa

Military factories produce everything under the Equipment screen, so all your infantry equipment, tanks, planes, and trucks. Ships are produced by dockyards instead.

I would say the same applies to military factories, personally - lots of focus trees give you factories.

Infrastructure seems like a good buy, and synthetic refineries are now actually somewhat viable (they weren't pre-WTT). Low level forts are reasonably cheap, though level 6 forts cost (collectively) about as much as a civilian factory.

Upgrading naval bases isn't a bad idea if you're going heavy into navy.
