ABSTRACT:
A projectile fuze contains a radio receiver, an oscillator, a counter and detonation means activated by an output signal from the counter. After firing the oscillator is started for a unit time period defined by successive signals transmitted to the projectile from a transmitter. The number of oscillations counted in the unit time period is multiplied by the number of unit time periods until detonation, calculated from range data, and transmitted to the projectile to set a counting limit for the counter before it produces an output signal. The signal containing the range data is used to clear the counter and restart the oscillator and may be used to render the radio receiver unresponsive to further signals. The projectile may have a booster or air-brake which is operated in flight by means of a second counter output signal or an output signal from an additional counter.
