Inert and pressure-actuated submunitions dispensing projectile

Patent image
NSWCDD

An inert axisymmetric projectile is provided for launching from a shipboard gun and dispersing submunitions at a target. The projectile includes a base plug, a sabot housing, a submunitions package, and a retainer ring. The sabot housing includes a plurality of sabot petals angularly arranged and attached to the plug. The housing includes a payload portion and a nose portion, with a passage corridor between these portions. The submunitions package is contained within the payload portion and constrained radially by the housing. The retainer ring constrains the petals for joining together. Upon launch aerodynamic pressure fractures the ring and causes the petals to unfurl, thereby releasing the submunitions package for dispersal.
