Abstract:
1. In a cartridge comprising a case with a head assembly and a load carrying projectile fitted to said case, said projectile having programmable electronics mounted therein at its forward end and an electrically conductive cylindrical container for tracer or base burner compound or a rocket motor system positioned at the rear of said projectile, an electromechanical electronics-setting circuit present within said cartridge for transmitting an electrical setting signal originating from an external fire control system through the head assembly to said programmable electronics, said circuit wherein the programmable electronics is separately coupled to the projectile at the forward end of the projectile by mounting means, said mounting means comprising: whereby, upon coupling of the programmable electronics to the projectile, the contact means, through the annular ring, provides a portion of the electromechanical circuit and with said electromechanical circuit having a path originating from said external firing control system, to an electrode present in said head assembly, to a first conductor, to the electrically conductive cylinder, to a second conductor, to the mounting means, to a third conductor, to said programmable electronics, returning via a surface of said cartridge to ground.
