The M104 155 mm projectile is a chemical artillery shell designed for use by the U.S. Army. It was specifically designed to carry about 11.7 pounds (5.3 kg) of sulfur mustard (H) or (HD) blister agent (distilled mustard).[5][6] As early as the 1960s, the shell was also filled with white phosphorus to be used for obscuration and signaling.[7]
