The invention is based on the concept of providing a digital data transmission of the fuze-timing data into a fuze-timable ammunition unit, for example with an HDB-3 (High-Density Bipolar) transmission code and voltage modulation. As is known from asynchronous data transmission, a start byte and a stop byte are respectively positioned in front of and behind the HDB-3 code, and are therefore components of thee fuze-timing data. The fuze-timing time is transmitted numerically as a data byte between the start and stop bytes.Accordingly, the ammunition unit ( 3 ) includes fuze-timing electronics ( 4 ), which comprise a (voltage) demodulator ( 30 ), a (current) modulator ( 31 ) and a microprocessor ( 32 ) having an RC-oscillator cycle counter ( 32.1 ), an RC oscillator ( 33 ), a fuze-timing counter ( 34 ) and an actuator end stage ( 36 ). A firing sensor ( 35 ) serves as the fuze-timing-time triggering element at the start of the flight phase. Additionally, operating data of the oscillator ( 33 ) are corrected, so simple RC oscillators can be used.
