History and design

Following World War I, militaries around the world began working to standardize calibers of ammunition within their countries. In the United States, the military began focusing on replacing the European-made 75 mm artillery shells with 105 mm and 155 mm shells.[4]

The M104 (along with the M110, which it shares many design elements with) was designed as a 155 mm artillery shell for use in the M114 howitzer. It is a Script error: No such module "convert". steel shell with a rotating band near the base, and a burster well that goes down the center of the shell. Filler of either sulfur mustard or white phosphorus is placed in the empty space and a fuze is fixed to the top before firing.[4]
