VLF Sonar Communication '67 Status.
Abstract
The problem is to develop a compact VLF Sonar Kit to provide remotely depolyed submerged submarines with a communication link to shore. Two types of projectors have been built and calibrated. Operational sea trials are beginning. Both are intended for quick installation in an empty torpedo tube whenever operationally required. The lower power, light weight version transmits in the 140 to 2000 cps band. The heavier, high power unit is primarily for use in the 25 to 50 cps band. It yields strong signals to shore based listening arrays at 3000 miles range or farther. The smaller, higher frequency unit is limited to about 100 miles usable range at present. Extensive operational sea trials are planned for fiscal 67. Towable hydrophone arrays will be used to appraise the practicability of two way VLF sonar communication by submarines.
