Australia’s Jindalee Operational Radar Network (JORN) will form the basis for Canada’s planned Arctic over-the-horizon radar system, potentially marking Australia’s largest defense export. The collaboration leverages decades of Australian expertise in high-frequency radar technology to address Canada’s needs for monitoring its vast northern region.[1][2]
Australia and Canada signed a technology partnership agreement in June 2025 to advance over-the-horizon radar research and development. The deal enables joint work on technical challenges for Arctic operations, further development of JORN, and planning for manufacturing Canada’s system. Australia’s Defence Science and Technology Group is partnering with Canada’s Defence Research and Development Canada and Department of National Defence Digital Services Group.[1][3][5]
Canada’s Arctic Over-the-Horizon Radar (A-OTHR) will use JORN’s core technology and principles, modified for Arctic conditions, as part of NORAD modernization. It detects air and maritime threats over long ranges by bouncing signals off the ionosphere. Initial capabilities are targeted by the end of 2029.[2][5]
Australia’s Capability Acquisition and Sustainment Group issued a request for tender to BAE Systems Australia for design, manufacture, and commissioning of the first stage. BAE has led JORN upgrades, including the ongoing Phase 6 midlife upgrade.[6]
Canadian Prime Minister Mark Carney viewed JORN during a visit to Australia, where officials demonstrated its capabilities. Air Vice-Marshal Martin Nussio noted mutual benefits from collaborative development, strengthening Australia’s sovereign industry. Chief Defence Scientist Professor Tanya Monro highlighted BAE’s long involvement in JORN advancements.[6]
The project is valued at around $6 billion CAD ($4 billion USD), with Canada planning $4.9 billion over six years and $38.6 billion over 20 years.[2][4]
