Since I have inspected all four Iowa class ships during their modernization in the 1980's and now have one a 25 minute drive from my house, I have never, ever seen a knuckle in that 1 1/2" thick STS armor deck in that area. Besides, the yellow lines you show are of the CIWS deck house on 03 level.
I happen to have a copy of the Mold Loft Offsets and believe me, there is NO KNUCKLE in that deck. What you are probably mis-interpreting is a Butt Strap of 5/8" thick steel plate, 15" wide riveted to the main deck plating but UNDER the 2 1/2" thick teakwood decking.
Umm, yeah. During decking replacements I've tripped over more butt straps than I care to remember.
