(3) Block stowage.
(a) Securing 750-pound bombs in deep tanks, in lower holds, or in any compartment with appreciable hull
curvature can be accomplished through construction of block-stow securing structures, as illustrated in figure 9-57. The
palletized bombs are first stowed parallel to the ship's center line in tight, vertical alignment. Two 4by 4-inch TM 55-
607/NAVSEA OP 3221 Rev 2 uprights bear against each row and are braced to the hull by means of 4by 4-inch kickers
bevel-cut to fit the curvature. Each tier of bombs must be braced to the hull with two kickers, as shown. The securing
structure is laced with 2by 3-inch minimum lumber; vertical lacers must be extended to the overhead to prevent any
vertical movement of the dunnage.
