Where i agree about not removing citadel because that would be broken as all hell. The Minotaur wasnt angling correctly at all, all of his Armour can autobounce 203 AP. Henri however can overmatch the minotaur, which is the most glorious thing to do at close range.
Not at short range. Those SHS have almost as much pen as the Henry. Gotta remember, bigger shell fired at a decent velocity, add in the extra factor that allows a larger wiggle room before bounce for USN shells. Minotar has to be literally at the perfect angle otherwise I'm going through that tin can like a hot knife through butter.
Hell at short ranges, you can citadel some battleships. Including Montana and Iowa.
