clip1515

Description

This fixed cartridge is fired from 90mm guns and is for antipersonnel use at both close  and long ranges. The cartridge is particularly effective against personnel in dense foliage.

The projectile consists of an aluminum forward body, a steel connector, and a hollow steel base. Threaded to the forward body is an aluminum fuze adapter containing four radially oriented detonators and an axially oriented flash tube, relay and detonator. The central steel flash tube connects the projectile base to the detonator in the fuze adapter. The body is loaded with flechettes and also contains a yellow dye mixture that serves as a spotting charge. A plastic bag of flake propellant is located in the hollow base. A mechanical time fuze is assembled to the fuze adapter, and a tracer is attached to the base of the projectile. The projectile is crimped to a cartridge case loosely filled with propellant and fitted with a percussion primer.
