A fuze is enabled, armed, and fired while indicating its status to remote command/receiver stations so that interconnected line charges and other ordnance items can be detonated with increased safety and reliability from a safe man-weapon separation distance. The fuze is responsive to remotely transmitted magneto-inductive command signals in the extremely low frequency (ELF) to very low frequency (VLF) range to change its status and to transmit magneto-inductive status signals in the ELF to VLF range confirming its status to at least one of the remote stations. Transmission and reception of magneto-inductive signals in the ELF to VLF range allow for a unique communication method that provides safe and reliable communication suitable to effect fuzing of explosive devices on the beach through seawater, air, earth, buildings, vegetation and sediment or any combination of these conditions.

[ We claim:] [1.]1. A fuze for ordnance responsive to magneto-inductive command signals in the ELF to VLF range from a remote station to change its status and to transmit magneto-inductive status signals in the ELF to VLF range to said remote station confirming said status, said command and status signals being transmitted in said ELF to VLF range to assure transmission reliably through ground, water, and air, said fuze having a receiver portion coupled to an antenna to receive said magneto-inductive command signals and a transmitter portion coupled to said antenna to transmit said magneto-inductive status signals and said receiver portion having high gain narrow band filter amplifiers receiving said magneto-inductive command signals, a demodulator-tone detector module coupled to said high gain narrow band filter amplifiers, output drivers coupled to said demodulator-tone detector module, and a safety, arming, and confirmation section.
