I read an essay that looked at the known facts and came to the
conclusion that a 38cm shell that lost its ballistic cap on impact
with the water, so it would strike nose-first, did in the Hood by
coming in underwater and under the belt, as the angles were wrong for
any other penetration.	The french had also tried to put some thought
into the underwater performance of their shells.
