The aircraft floating smoke bombs for Naval use are filled with HC smoke mix (Type A, composed of hexachlorethane, zinc dust, ammonium perchlorate, ammonium chloride and magnesium carbonate), which upon burning produces a dense white smoke. The 100-lb. Smoke Bomb Mark 3 Mod 0 produces smoke for 6 to 10 minutes, the 50-lb. Smoke Bomb Mark 1 Mod 1 produces smoke for 3.0 to 5 minutes, and the 50-lb. Smoke Bomb Mark 1 Mod 2 produces smoke for 6 to 7.5 minutes. All floating smoke bombs are safe for take-off and landing anywhere, including carriers. These smoke bombs are floating bombs de-signed for dropping from aircraft for the purpose of creating a smoke screen, primarily on the surface of a body of water. By means of the fuze adapter Mark 1 Mod 0 these bombs will also function on land impact.
