Until now, I've had the tendency to equip all of my non-combat units (colony ship, advanced transport tropps, space miners and constructos) with the fastest engins that I could afford both thanks to miniaturization tech and new drives technologies.
As result, I've seen the following effects:
- ships become extremely expensive to build and mantain
- only the most powerful planets can build them at a decent speed
- faster are the ships, lesser is the time that they need to reach a destination and this reduce the maintenance cost for those shame ships (if colony or constructors) and the extra speed makes more convenient to build those ships if they have to quickly reach a far away destination.
This may sound quite obvious, but I've also seen that the Ion drive looks like the panacea. At the top of miniaturization and drives technology, the Ion drive looks as the cheapest of all engines: if I fill any ship only with Ion drives, it will be always cheaper to build rather than other ships with different engines that provide the same global speed.
Now, since it is really hard to optimize ships production on very large empires, I was thinking to use the Ion drive only for non-combat units due to the great positive balance among extra speed and production cost, which would make those ships affordable even by planets with a poor production.
What do you think about?
Also, even if unrelated to this question, does it have any meaning to put shields on an ship without weapons, that can't shoot back?
