In 1963 the US Navy took control of the southern end of Fort Miles including Batteries Smith and Herring to establish a SOSUS listening facility.
SOSUS hydrophones, laid on the seabed and connected by underwater cables, were used, beginning in the 1950s, by the U.S. Navy to track movement of Soviet submarines during the Cold War along a line from Greenland, Iceland and the United Kingdom known as the GIUK gap.
