The american 127mm Secondary is broken on some ships. For example on the new USS Maryland. It can never fully shoot in two directions. Let’s say you have two planes on each side. The 127mm on one side will function completely normal, but on the other side, only two are working, while the other two are pointing to the other side (???). We need to have an invisible barrier in the middle of these american Super-Dreadnoughts so our secondary won’t goof around. To clearify what I mean, I will show you a picture of it.
