Bomb, 100 lb Smoke WP, AN-M47A4, or Smoke PWP, AN-M47A3
Description
Smoke bomb AN-M47A4 is approximately 51.9 inches long and weighs approximately 105 pounds when filled with PWP and approximately 131 pounds when filled with WP. It is approximately 8.00 inches in diameter and has a rounded nose, a truncated conical tail section, and a fixed tail fin. The complete round consists of a bomb body, filler, a burster, a fuze, and an arming wire. Smoke bomb AN-M47A4 is essentially the same as incendiary bomb AN-M47A3 except for the filler, the burster, and the suspension lugs, which are of heavier construction in bomb AN-M47A4.
An earlier model of bomb AN-M47A4 was the AN-M47A3. The two bombs are identical except that the AN-M47A3 has more lightly-constructed suspension lugs and is authorized for filling with PWP only.
Hazardous Components
The bomb is filled during manufacture with either 74 pounds of PWP or 100 pounds of WP.
A burster AN-M20 is used in a bomb filled with PWP; a burster M18 is used in a bomb filled with WP. The burster is installed in the bomb during assembly.
The preferred fuze is nose bomb fuze AN-M159. Nose bomb fuze AN-M126A1 is an authorized alternate.
