Abstract
In an ammunition fuzing system, a fuze setter is inductively coupled with an electronic fuze incorporated in the projectile of an ammunition round being fed to a rapid-fire cannon to transmit power supply charging energy and fuze-setting data thereto. A detonation counter is incremented at a high counting rate to accumulate a projectile flight time count indicative of the fuze-setting data. A conformation signal is transmitted to the fuze setter for determination that the flight time count acceptably corresponds to the setting data. Upon projectile launch, the detonation counter is decremented at a low counting rate and functions the projectile warhead when decremented to zero.
