1. The 100-lb. Aircraft Smoke Bomb Mark 3 Mod 0 (figs. 1 & 2). The 100-lb. Smoke Bomb Mark 3 Mod 0 consists of an aluminum nose casting which carries the smoke char-ge, a hollow wood float to provide bouyancy, and four tail fins to provide goog flight characteristics. The bomb is shipped with a water-impact Fuze Mark 3 Mod 1 in the nose. At the tail of the float is a valve cap with a valve to prevent water from leaking into the interior of the bomb and to act as a baffle giving distribution to the smoke. The bomb weighs 102 pounds, loaded and fuzed, and contains 59 pounds of HC smoke mix-ture. The outside dimensions of the bomb are 48.5 inches long by 10.25 inches in diame-ter. The bomb has two movable suspension bands.
