According to the rules
"A unit with the Internal Bomb Bay Quirk may use internal cargo space as a bomb bay, although doing so carries a risk; while up to 6 bombs may be dropped from this bomb bay in a single turn, fire from the ground has a chance of striking through the open bomb bay doors and detonate any remaining ordnance within the bay."
In the case of larger craft like drop ships is it acceptable to take the quirk once per individual cargo bay due to the ships vastly larger size when compared to an ASF?
