Abstract
A multi-piece ammunition round includes an aft cartridge, a forward cartridge, and a projectile disposed in an end-to-end nested, serial arrangement. The aft and forward cartridges each contain a charge of propellant. The projectile contains a high explosive filler and a projectile fuze. The round also includes a propellant-primer electrical ignition interconnect arrangement associated with the aft and forward cartridges. The ignition interconnect arrangement includes a multi-element primer disposed in a base of the aft cartridge for contact by a firing mechanism of a gun system and communicating with the propellant charge contained in the aft cartridge, an electrical interconnect interface disposed between the aft and forward cartridges, an electro-explosive device disposed in the propellant charge contained in the forward cartridge, a first plurality of insulated electrical conductors disposed in the aft cartridge and electrically connecting the primer with the electrical interconnect interface, and a second plurality of insulated electrical conductors disposed in the forward cartridge and electrically connecting the interconnect interface with the electro-explosive device.
