My mistake, I misunderstood your post. That damage is from attacking it's target, depending on the target. Comparatively tanks and artillery do very little damage (5 or under). I haven't been able to test as much as I had hoped because the AI didn't seem very keen on building fighters or air units in general unless they were ahead. I'm still not sure how air combat works because there were times I was intercepted but the damage was no different then what it normally would be. So it does seem to me that interception, when procced, has a chance to miss. It doesn't help I'm unable to see their promotions and that the damage doesn't appear to be reflected separately in the UI. It seemed all rather frustratingly random I decided to nuke their cities. It may be they all chose the ace pilot line, like how carriers always choose pilot deck. By the same token, ground AA units seem to do absolutely nothing. They appear to only being able to defend against one aircraft once per turn. However their presence results in no change in the damage I take. With a B17, bombarding a city usually resulted in about 30-40 damage. Bombarding a SAM is about 30. Missile cruiser a little over 50. These values are always the same with or without a nearby SAM. Other issues of note; *The world made no mention when I nuked Carthage 3 times in my first Atomic war with them. All that happened was a -50 diplo modifier with Carthage. The next war I used 6 atomic bombs turn 1 and still nothing. A couple of other cities had been nuked as well in other AI vs AI wars. It's worth noting I may not have been the first one to use nukes. Another AI built the manhattan project before I did. I do believe though that my actions did result in a nuclear ban treaty being proposed and passed (by a different AI), I just didn't suffer any diplomatic repercussions for it. Despite my efforts I was not able to repeal this *I was unable to use air units on a missile cruiser with dreadnought 3 when it had sub 50 health. Oh and Spoiler : I wouldn't be opposed to a nerf of 1% growth per follower.
