Army Command and Administrative Network (ACAN)

Have just published a new web page on ACAN.

The US Army Signal Corps established a radio network in Australia known as Army Command and Administrative Network (ACAN) with radio stations located in Melbourne, Brisbane, Townsville, Sydney and Darwin.

This network was also used to provide a telephone voice scrambling circuit at General MacArthur's GHQ SWPA known as SIGSALY (Green Hornet). This highly classified voice circuit was not declassified until around 1976.
