Description
This smoke cartridge is fired in 60mm mortars M2 or M19 and is used for screening and spotting.
The complete round consists of a projectile body with a PD fuze, a fin assembly and a 2 inch extension, four increments of propellant charge, an ignition cartridge, and a percussion primer. The projectile body is a relatively thin walled steel cylinder with a conical base, and is filled with a charge of white phosphorous. The base is internally threaded to accept the fin assembly. The projectile nose is fitted with a steel adapter, internally threaded to accept the fuze, and designed to hold the sleeve of the burster assembly. One of two types of burster assemblies is used, differing only in the construction of the steel burster casing. Both carry the same designation. The burster charge consists of tetryl pellets under pressure, and the burster casing is press-fitted into the adapter in the projectile nose.
Smoke cartridge M302E1 differs from cartridge M302 in that a 2-inch fin extension has been added between the projectile and the fin assembly, and propellant increment charge XM181 (four increments) has replaced propellant increment charge M3A1.
