Description
The forward half of the bomb is painted black and has a green band around the nose. The after half, including the tail cone, fins, and struts, is painted white.
The bomb is of three piece construction. A steel nose piece is attached to a tubular steel body by screws. A tail cone is attached to a collar by screws. The collar fits into the after end of the body and is held there by screws. Four slots in the tail cone allow the smoke to escape when the burster charge ruptures the metal tank.
Four steel fins are welded to the tail cone and are braced by a single set of box type tail struts.
The purpose of the glass disk filling in practice bombs is to lessen the damage to the target ship while still preserving the correct trajectory and ballistics of the bomb.
Hazardous Components
The nose is filled with fine gravel held in place by a steel separating plate. The body contains 15 glass disks 6 1/2 inches in diameter and 3/4 inch thick. A spotting charge of titanium tetrachloride and a picric burster are contained in a tank in the apex of the tail cone. A wooden block fills the remainder of the cone.
