HMAS Harman is a Royal Australian Navy (RAN) base that serves as a communications and logistics facility. The main base is located in the Australian capital of Canberra, and is geographically recognised as the suburb of Harman (postcode 2600) in the District of Jerrabomberra. Established in the late 1930s as the Royal Australian Navy Wireless/Transmitting Station Canberra, the facility was commissioned into the RAN as a stone frigate in 1943. In addition to its communications and logistics roles, the base hosts reserve units from both the Australian Army Reserves and Royal Australian Air Force Reserves, as well as cadet units from all three branches of the Australian Defence Force Cadets.
The base is also reported to be a major contributor to the U.S. National Security Agency's XKeyscore surveillance program.
The commander of the base is Commander David Luck, RAN.
History
In 1924, the Imperial Defence Committee's Communications Sub-Committee examined Australian coastal radio stations, and recommended the modernisation of the stations at Darwin, Perth, Rabaul, and Townsville. A year later, the Australian Commonwealth Naval Board (ACNB) made a recommendation that two wireless stations be provided for the Navy in Canberra and Darwin. These would be strategic stations in addition to the coastal stations. Canberra was chosen as its distance from the coast would increase its protection from attack. Planning continued in 1935, where a new Canberra station would add to the coverage area of Rugby, and function as a fall back in the event of the destruction of submarine cables, or the Hong Kong or Singapore wireless telegraphy stations. The Australian government decided to build a receiving and a transmitting station in Canberra in 1937, with the transmitting station sited at Ginninderra Creek in Belconnen, approximately north-west of the main receiving facility.
Construction of the transmission facility (Royal Australian Navy Wireless/Transmitting Station Canberra) commenced in November 1938. The facility established on 20 April 1939 and started transmitting on 22 December 1939. Work on the main facility started in early 1939, with the facility registered with the Postmaster General's Department on 20 July 1939 under the name 'Harman'. The name was derived from the surnames of the two officers responsible for naming the new naval stations: Commander Neville Harvey of the Royal Navy, and RAN Lieutenant Commander Jack Bolton Newman. As the ACNB had paid little attention to the proposals for the names of previous wireless stations before implementing them, the two men proposed their combined names for the Canberra facility, which was accepted without comment.
