155mm M483A1 Projectile - USA

This is the American 155mm M483A1, a spin-stabilized, base-ejecting, separately loading, Dual-Purpose Improved Convention-Munition (DPICM) carrier, projectile consisting of a forged steel alloy body lined internally with glass fiber, an expulsion charge assembly, a pusher plate, 88 individual submunitions and an aluminum ogive and a short hollow boat-tailed aluminum base plug.

A metal drive band and the plastic obturating band are located close to the base of the projectile, both are protected by a plastic grommet which is removed before loading.

In operation, the fuze functions at the selected time during the projectile's trajectory and initiates a 58g expulsion charge of M10 propellant located at the base of the fuze well.

The resultant increase in internal pressure against the pressure plate and the contents forces the base plug to shear and the contents of the projectile are ejected, where centrifugal forces disperse the entire submunition load radially from the projectile's line of flight.
