Abstract
The system for electrically identifying and firing ammunition is especially advantageous for firing military rockets from a multiple tube rocket launcher. The system provides an electrical signal for initially identifying the type of rocket or other ammunition loaded and ready to fire in each launching tube. The identifying signal is derived from the firing wire or lead which is also used to fire the rocket. In each rocket an igniter and a diode rectifier are connected in series in the firing circuit which usually extends between the firing lead and a common ground. The diode rectifier is polarized to conduct the firing current while being nonconductive as to the signal current which is oppositely polarized. Each rocket includes an identification impedance having a nature to identify the type of rocket. The different types of rockets have measurably different identification impedances.
