Seems fun. Is going to be limited by a fixed number of rounds or for damage to the ship with dice rolling?
Probably not a turn limit, but rather ship damage being the pseudo-counter. Damage to the ship is currently handled like damage to a boss unit. The ship has X hull points and (currently) 1 armor, and each successful attack (>1 successes, counting the armor value) deals damage as if the ship were a boss unit.
