You can re-fit ships by cliking on the Looks like green triangle, in upper task bar of game, you must lst have ships out of a fleet, and you must have a space yard present either over planet of yard ship, or Station with one on it, clik on the ship or base u want to re-fit, on right you should see the retro-fit button highlighted, clik on it and wallaaaaa, However, if you are way ahead in tech, you may have to re-fit in stages if to far ahead.. can't retro units, you must either add the new to them or jettison the old ones to make room for the new ones..

just some ideas mac
