Description
This projectile is fired from 155mm howitzers to produce a toxic effect on personnel and to contaminate habitable areas.
The projectile is a hollow steel casing containing a burster extending through the center. The burster tube is loaded with tetrytol and the remaining space within the projectile is filled with 11.7 lb of Agent H or Agent HD. A lifting plug is installed in the nose fuze cavity for use in shipping and handling, A rotating band encircles the projectile case near the base and is protected by a grommet to be removed before loading the projectile in the weapon. A PD fuze is normally used with the projectile, The ballistics are the same as the HE, M107 projectile.
Older projectiles are gray with green markings and two green bands. Newer manufactured projectiles are blue-gray with green markings, two green bands and one yellow band (if burstered).
Functioning
When the weapon is fired, the burning propellant generates rapidly expanding gases to propel the projectile through the barrel with the velocity required to reach the target. The soft alloy of the rotating band engages the barrel rifling to impart spin to the projectile for stability in flight, The rotating band also forms a seal to prevent escape of gas pressure past the projectile, The PD fuze functions on impact to explode the burster. The burster ruptures the projectile case and disperses the agent.
