Abstract

A shell-firing barrel weapon system for a single shot, semi-automatic or fully automatic firing, including a rifled barrel comprising a programming member for programming with programming pulses fuses in shells fired from the weapon before or in conjunction with firing of the shells. At least one contact is located in the barrel of the weapon and connected to the programming member for transmitting a programming pulse from the programming member to the fuses of the shells. The at least one contact is electrically insulated from the barrel and protrudes into the barrel beyond bars of rifling of the barrel. An electrically conductive contact ring is concentrically arranged on the shells. The contact ring is electrically insulated from main parts of the shells and has an external diameter that is smaller than a diameter of the bars of the rifling of the barrel. The contact ring is positioned on the shells such that when the shell is located in a cartridge chamber of the weapon the contact ring directly contacts the contact device. Electric feedback of a programming pulse from the programming member takes place via contact between the main parts of the shells and an inside of the barre…
