Is it the angle of obliquity of the decapping layer that is calculated? Or the angle of obliquity of the underlying belt?
I know the South Dakota's main belt was inclined at 19 degrees. Was the outer layer inclined as well? And if not, I think it would be the obliquity angle of the outermost belt, not that of the interior belt.
Against bombs though it does not seem that it would be as effective - Except for perhaps setting off a HE bomb with a very short or no delay. With the layered decks you are then perhaps decreasing the value of the armor as it's easier to penetrate when it's 3 separate layers.
Any idea what thickness was thought needed to set off a bomb fuse?
