Naval Communication Station Harold E. Holt is located on the North West coast of Australia, 6 km north of Exmouth, Western Australia. This town was built to service the station.
The station was commissioned on September 16, 1967. On September 20, 1968, the station was officially renamed to U.S. Naval Communication Station Harold E. Holt in memory of the late Harold Holt, former Prime Minister of Australia, who died three months after the station was commissioned.
The station provides very low frequency (VLF) radio transmission to United States Navy and Royal Australian Navy ships and submarines in the western Pacific Ocean and eastern Indian Ocean. It is with a transmission power of 1000 kilowatts the most powerful transmission station on the Southern hemisphere. The station is also suspected of being a part of the US signals intelligence and analysis network ECHELON.
The station features thirteen tall radio towers. The tallest tower is called Tower Zero and is 387 metres tall, making it (at the time it was built) the tallest man-made structure in the Southern Hemisphere. Six towers are evenly placed in a circle around Tower Zero. The other six towers are evenly placed in a larger circle around Tower Zero. All these towers are 364 metres tall.
During July 2002, the Australian Navy handed over operation of the station to the Defence Materiel Organisation.
The base is run under contract by Boeing Australia, Ltd.
An extremely powerful very large diameter telescope is being transferred here as it has finished testing stateside. It will watch satellites, space debris, and continuing the search for Near Earth Objects. A description can be found in the Popular Mechanics magazine.
