Problems with bases

Unless sometihng has changed since the last time this question was asked, you can't, your best bet is to do base upgrading by copying the original base so the crew quaters and life support facilities don't change, bit late now but helpful in the future.

Bases away from Planets build slowly and quickly become obsalesent as they are dificult to refit the best way to get round this is to arm them with fighters satalites and drones all of which can be state of the art even on an obselete base. Its also rather fact of life in the game that not every thing can be cutting edge all the time because of resorce and build rate limitations.

All of this is esentialy the complex balencing act which is the game. you pays your resorces & takes your pick

Research computers and replace the crew with a master computer.
