Hey,
first of all: waoh, what a great project!
as far as I remember it was only possible to deploy Fighters for Planetary Defense if the Planet has a military spacedock(spaceport?, sry, I don't know how it's named exactly in the englisch version).
In Open IG it's not related so I can deploy Fighters right from the beginning to any planet.
I'm not quite sure so I asked here instead of writing a new issue, hope you doesn't mind.

I really appreciate your effort to get the game localized.
But the German translation drives me crazy ;) Never seen so many grammar errors and misspelled words, it's like you google-translated it :-P
I tried to check how much time it would cost to fix this and I saw that not all strings are even loaded out of resources, you should fix this to help get the game localized :)
