Dunkerque ' s face - hardened turret roof , designed to maximize resistance to ap bombs from aircraft , was hit by hood and is a perfect example of this problem
敦刻尔克号表面硬化炮塔顶部的设计原意是最大限度地抗击空中落下的穿甲炸弹，却被胡德号击中就是个完美得例子。
However , when extremely high oblique impacts occurred ( 55 degrees or more ) , as on turret roofs and decks , face - hardened armor , due to its brittleness , was a very poor choice since it could break and throw pieces into the region behind it even if the shell glanced off
然而当炮弹以极大的弹着倾斜角（ 55度或以上）击中炮塔顶部和甲板时，由于装甲的脆性，即便炮弹只是擦过，装甲的背面也会破碎飞散，这时表面硬化装甲便是个拙劣的选择了。
