Abstract: An electronically tracked ordnance having a positioning component, a power supply, and a transmitter. The power supply includes a deformable electrolyte component such that both an anode and a cathode are contacted by the deformable electrolyte component when subjected to acceleration upon firing of the ordnance from a firearm or from deceleration from striking a target. This closes the electrical circuit, thus powering the positioning component and transmitter for transmitting the position of the ordnance.

Abstract: An active electromagnetic influence firing system has transmitter coils and eceiver coils mounted on a single warhead section. One set of receiver coils has vertical look capability for detecting surface ships and another set has 360.degree. look capability for detecting submarines. An influence electronics package automatically nulls out directly induced electromagnetic radiation and passes only the signature received from targets. Amplitude, duration, and frequency criteria implemented by circuitry in the influence electronics package determine whether there is a valid target.

Abstract: Electronic intervalometer circuitry utilizing a combination of mechanically ctuated switches and solid state logic components to carry out a predetermined program of deployment and sequential detonations of a plurality of underwater explosive charges.
