Project ELF electromagnetic compatibility assurance program - A status report

The U.S. Navy is presently planning an extremely low frequency (ELF) communications system to improve operational control and reduce the detection probability of its submarine fleet. An integral component of the shore-based ELF transmitting facility development activity is the Environmental Compatibility Assurance Program (ECAP) which was instituted by the Navy during the early stages of program concept development. The principal components of the ECAP include: electromagnetic compatibility, biological/ecological monitoring, and environmental documentation. The current activities being performed in association with each of these program elements are discussed. The necessary ECAP requirements for achieving a fully operational ELF facility are also reviewed.
