Construction of body: The bomb body is constructed of one piece of forged machined steel. There are eight recesses cut in the nose presumably to hold a windshield if the case is used as a projectile. A male base plate which has two fuze pockets is screwed into the after end of the body. The tail cone is formed of rolled sheet steel (3/32 inch) welded down one side. Twelve screws fasten the unreinforced base of the cone to the base plate of the bomb which has holes drilled around the edge to receive the screws. Three hinged doors in the cone permit access to the fuze pockets. Two vane assembly supporting rings are located at the apex of the cone. These rings are constructed to receive the B-2 (b) vane assembly bushings which are held in place by set screws. Slots in the tail cone are located beneath the supporting rings to permit passage of the reach rods from the fuze bodies to the vane assemblies.

Construction of tail: Four sheet-steel fins are spot welded to the tail cone and are bra-ced by a single set box-type struts.
