Hood's armor protection depends on range and shell size

How effective would Hood's armor be against 8-inch and larger guns, given the tapering belt?

At likely engagement ranges it is judged effective against the first hits, particularly from 8-inch guns, with less confidence against heavier shells.

The belt's taper toward either end is part of the concern about Hood facing 8-inch and larger shells. Her design began as a battlecruiser and changed during construction. At likely engagement ranges, the protection is judged effective against initial hits, with 8-inch fire a less demanding threat than larger shells. This qualitative assessment establishes neither a precise immunity zone nor how many hits she could withstand.
