This includes the sixteen inch guns and rotating turrets. The stationary portion of the No. II turret is to be cut back to the deck. All deck openings, including the turrets are to be sealed with reinforced concrete slabs.
The main deck forward of Frame 24 and aft of Frame 140 is to be strengthened with a reinforced concrete slab.
The shell plating forward of Frame #24 and aft of Frame #140 is to be reinforced in way of living quarters and usable spaces.
An eight foot doorway is to be cut through the blister and armor plating, about midships, to provide access to the Third Deck from the outside. This doorway is to be enclosed with a blast-proof door, and will be about on level with grade after emplacement.
