not coded yet, i think XD
the way to "merge" them is to scrap them and then rebuild immediately.. no resource wasted, but you'll be transferring the upkeep to the new planet where it's built.. and obviously you can't do it in the middle of nowhere.

it's extremely silly to have it fixed at 5% for 1 ship type, if that's true... makes no sense at all. i'll probably have around 30-40 odd cruisers when i "merge" the ships to form a "big" fleet to try again. bet it's still too small.
when they arrive to be merged.... i'll link jump more resources there to build more ships...
