Open up the .entity file of the selected ship inside notepad or word and up the value :MaxAvailableCommandPoints, lovated usually at the very bottom or in the middle section (well files are pretty small so it cshouldnt take long to find)!
Up it to the desired value and VOILA! You got yourself a super carrier!
Be aware though that having a ship with 30 + squadrons will cause a game lag if you dont have the latest top of the line gaming pc....!!!
Hope it helped!!!
