Weapons, engines and mods, Oh my!

Yes it was something about those lines.
It may be related the only time I tried to play in proportions I went bankrupt under the manteinance of my ships and the micromanaging hell pf my colonies.

But no, larger sizes should REDUCE, not increase cost and manteinance.
Of course that building and mantaining large ships cost much more than building a small one.
And in many cases using a ship only as big a needed is a good way to save.
But in real-world economies, large scale does significantly reduce costs. For example jumbojets and supertankers.
Why do you think they keep trying to make those things even larger?
They may be harder to build, require more technical refinenemts than smaller vessels, and of course each one needs a much larger inVersion to be built, but in the large picture they save money.
