Ship refitting
I recently got a mail about how one deals with upgrading / refitting ships you have already built.
1) To make a ship you need to make a ship design (a template) this says which hull and components to use.
2) When you build a ship, it has to be based on a template you have designed.
3) You can change the template at any time (add, change or remove components), this does NOT affect the ships already built.
4) To upgrade a ship just move it to a system with a shipyard (or possibly a starbase, when implemented) and select the "refit" action
5) You can now select any template you have with the correct hull type (you cant upgrade a miranda class ship to be excelsior class)
6) The ship will be out of action for X number of turns (based on how big the changes to the components are).
7) Ships out of action can not defend themselves so refitting an entire fleet could be dangerous

. And that's my opinion...
