Type of filling: Three cylindrical steel canisters each containing 87 white phosphorus fil-led cylindrical steel pellets. Each canister has a central exploder tube filled with type 98 explosive. A heavy wax coating covers each canister.

Dimension of filling:

Length of canister: 7 1/4 inches.

Length of pellet: 1 1/4 inches.

Diameter of pellet: 1 1/8 inch.

Diameter of exploder tube: 1 7/16 inch.

Weight of individual canister: 24 pounds.

Weight of filling: 3 canisters, 72 pounds; tail cone charge, 11.2 pounds.

Total weight of bomb: 118 pounds.

Charge/weight ratio: 71 percent.

Construction of body: The bomb consists of a nosepiece, body and tail assembly. The conical-shaped nosepiece is welded to the body and has a steel plate welded where the fuze pocket would be. The cavity in the nose-piece is filled with a wooden block. The body is cylindrical in shape and is welded longitudinally. The tail cone is welded to a coupling ring which fits into the body and is held there by a single row of screws. A burs-ter charge of cast type 98 explosive is contained in the tail cone. A perforated steel plate separates the explosive from the incendiary filling.

Construction of tail: The tail cone is welded longitudinally. Four angled fins are welded to the cone and braced by a single set of box-type struts. The angle of these fins im-parts a counter-clockwise rotation in flight to the bomb, thereby arming the clockwise fuze.

Operation: Upon release from the plane the aerial burst fuze functions initiating the tail cone charge which detonates the central burster tube. The bomb case and canisters are ruptured scattering the incendiary pellets. The white phosphorus is ignited when it is ex-posed to the air.
