What I got from it was that in order for it to "repulse" bombs (ever improving/enlarging) it would be to "top heavy" to sail, and when one did go through, the blast was contained and inflicted structural damage. Much worse than a holed flight deck. Having your deck blow off and still floating, is preferable to losing structural integrity.
It was 3" thick (front of a Sherman), but would have to be (?) 8-10 to get bombs to bounce off (so to speak).
It has it pro's & con's. Not unlike someone else telling you what kind of vehicle to drive, or how his is better, yada yada
Along with the smaller air group, which in fact was the best way to prevent damage from arriving, rather than to let it come and absorb it.
What works somewhere, does not work everywhere.
It's called Vuja De...= this kinda $@#% has never happened before!
