US Cartridge, 75mm Smoke WP, M64




This cartridge is used to produce smoke for screening and spotting.

Projectile M64 is assembled loose to a cartridge case of the M5 series and uses the same propelling charge and primers as high explosive cartridge M48. The projectile body, a steel casing with a boattailed base, contains 1.34 pounds of white phosphorus (WP). The projectile body is internally threaded at the nose to receive a steel adapter which accommodates the fuze and press-fitted burster casing M6. A burster, which consists of tetryl pellets loaded under pressure in an aluminum-alloy tube, is retained in the burster casing by a burster initiator. The burster initiator contains a tetryl pellet (weighing approximately 33 grains) and an M17 detonator. It is held in position by a snap ring which secures it to the steel adapter.
