Doesn't matter if it's a weapon, a fighter wing, I now see that it can look very misleading when a ship has "1x fighter bay" but you can't actually change what's in it, probably shouldn't be listed under mounts. Same as built in weapons, should probably be a bit more obvious "hey! this comes with the ship".
Think built in hullmods could also stand to be more obvious, this part is not hugely important but it's also nice to know for new folks.
Elegant way to do this is maybe change the colour of it so it's more clear, and list it in the beginning like with hullmods. Good example are s-mods on ships you want to recover, you can immediately tell what's on there permanently.
