Apparatus and process for providing a communication link between separate submersibles and, in particularly, for providing communication between a launched submersible and a host submersible. A thread of polyelectrolytic material is provided in electrical communication with a launched submersible prior to launch and payed out and stretched as the launched submersible extends a distance from the host submersible to permit secure communication between the submersible, transmission of command signals for guidance and arming/disarming, from the host to the launched submersible, and to receive data from deployed sensors. The conductive thread includes an organic solvent having dispersed therein a first polymer consisting of a water insoluble polymer that serves as the conductive polymer backbone and a second polymer consisting of a semi-water soluble high molecular weight polymer that effectively surrounds the conductive polymer backbone. The polymer components may be made from monomers on board the host submersible, if desired. When the communication link is no longer needed, self destruction by command or time actuated, leaving very little residual pollutants or evidence of the communication link, or any other indication of electronic information transmission.
