M121 155mm Projectile
The M121 155mm projectile starts as a hollow steel shell. GB nerve gas agent is added and sealed inside by pressing the burster well into the body. The M37 tetrytol burster is then installed into the burster well. The fuze adapter is screwed in and staked to the body. Next, the lower interior threads of the fuze adapter are coated with sealing compound or cement, and the fuze well cup is screwed down into the fuze adapter. The lifting plug is then screwed into the fuze adapter. The projectiles are stored unfuzed with 8 rounds per wooden pallet.
The M121A1 can be filled with either GB or VX nerve gas.
