US Projectile, 75mm Chemical, Mk II

 

clip2324

Description

The round consisted of the body, which contained the agent, the gaine tube (adapter and booster casing), which screwed into the nose of the round and contained the bursting charge, and the bursting charge, which consisted of a small quantity of high explosive sufficient to open the round, and in some cases, atomize the liquid content. Since most of the gases used entered the round as liquids, they expanded as liquids when heated, and a space was left for this expansion by only partially filling the round.

Three fuzes were normally used with this round, which was tapped through the nose to receive the adapter for French-type fuzes. The fuzes were: the U.S. Mk III; French I.A.L., Model 1916; and French I.A., Model 1915.
