A stacked ordnance device provides a disposable and non reusable projectile weapon for passive area defense or denial. A stacked ordnance device has multiple projectiles and charges positioned sequentially in a barrel. A sensing module triggers a control module to enter a firing sequence. The firing sequence is the order and timing by which an electronic ignition system ignites firing charges and thereby shoots the projectiles. A mount positions the stacked ordnance device. The controller can also trigger a disabler that renders the stacked ordnance device unfit for subsequent use.
