The aircraft carriers that I've seen all have their flight decks at or above y 70. The limit is necessary to prevent fighters and bombers from attacking ships just above the ocean surface, where they are outside the firing arcs of AA guns, and too nimble and low to be countered by ships' main guns

Well... My aircraft carrier has deck on y68 ffs

You selling djmax?

well, this confusion could've all been avoided if planes had to keep moving forward at high speed instead of just floating around... also this would give more utility to fireball dispensers!
