The Jindalee Operational Radar Network (JORN) is a multi-billion dollar investment supporting three over-the-horizon radar systems that use HF radar and ionospheric reflection to provide surveillance coverage of Australia’s northern air and sea approaches.
Invented by Defence Science and Technology in South Australia, the high-frequency system is supported from South Australia by BAE Systems Australia, with the command and control element, 1 Remote Sensor Unit, based at RAAF Base Edinburgh. The JORN will receive significant upgrades over the next decade, with the $1.2 billion enhancement set to create more than 500 highly technical jobs, many of them in South Australia.
