A fuze having an impact delay implemented by strobing the count from a time-of-flight counter to set a down counter after an impact is sensed and then decrementing the down counter to a predetermined count at which point a firing signal is passed.

A timer for a fuze actuation system, having an impact sensor and having an output circuit, comprising: an oscillator; a frequency divider coupled to said oscillator; a time-of-flight counter coupled to said frequency divider; an arming latch coupled to said time-of-flight counter; an impact latch coupled to said arming latch and to the impact sensor; a strobe control coupled to said impact latch; a down counter coupled to said impact latch and coupled to said oscillator; and a plurality of data gates, each coupled to said strobe control, each coupled to said down counter and each coupled to said time-of-flight counter.
