Naval Communication Station Harold E Holt North West Cape Austrilla

Naval Communication Station Harold E. Holt, located at North West Cape in Western Australia, was commissioned in 1967 as a joint United States-Australian facility. Its primary mission was to provide very low frequency (VLF) radio communications to United States and Royal Australian Navy submarines operating in the Indian and Western Pacific Oceans. The base featured a powerful VLF transmitter and became a critical communications link during the Cold War era. In 1992, the station was transferred to full Australian control, though it continues to support allied defense communications today.
