I never touch my CV squadrons as too many bad things can happen. However I believe, though others will be more accurate in their replies speaking from first hand experience, that to achieve what you want to do , you have to create a fragment. Hence transfer the unit off the CV and put it ashore. When you have a few damaged aircraft, transfer the unit back onto the CV and disband the shore based fragment. This may work, but as I said, I personally don't have first hand experience.
thanks, but how to create this fragment ?
I mean, there is no button appearing on my Sqdn to divide it, while it's on it's CV , in port. Is there a condition i don' meet and i don't know? Must the sqdn have damaged planes ?? (if so, i must wait, having receive absolutely no loss at all at wake...i mean for the sqdn, because the base fall at the first turn .....)
