Abstract

A munition includes a projectile and a propellant unit. The propellant unit includes a shell having a cylindrical configuration centered on a longitudinal central axis of the munition. The shell has a cylinder opening that receives a cylinder. The cylinder is selectively rotatable in the cylinder opening about a cylinder axis, offset from the munition axis, between a plurality of firing positions. The cylinder has a plurality of propellant chambers each with a respective propellant charge. The propellant chambers are located in the cylinder so that when the cylinder is in a firing position one of the propellant chambers is on munition axis.
