Abstract :
Early extremely low-frequency (ELF) research and the implementation of Project Sanguine to meet the Navy\´s need for secure transmission to submerged fleet ballistic missile (FBM) submarines are outlined. The 1963 "Intensive Test," which proved the feasibility of ELF reception by a submarine at operational depths, is highlighted.
