Australia signs a defence export agreement with Canada to supply an over-the-horizon radar system designed to support monitoring, including in the Arctic. Multiple outlets report it is the largest defence export deal Australia has concluded, with figures in coverage ranging from about $1.75 billion to $2.5 billion depending on how the deal value is described. Canada is purchasing the radar technology and modelling it on Australia’s existing JORN over-the-horizon radar system, according to ABC Australia and other reports. SBS News says the Australian radar system has been in service for more than 40 years, indicating the exported capability is based on long-running operational technology rather than a prototype. Several outlets describe the arrangement as Australia and Canada signing the agreement and provide context that the radar would be built or deployed in Canada as part of the procurement. Coverage also notes that Canadian leadership previously selected the Australian radar system over comparable U.S. options, as reported by Fortune. Overall, the reporting focuses on the scale of the deal, the specific radar capability involved, and its intended role in Arctic and broader monitoring needs.
