Canada Buys Advanced Australian Defence Radar for $1.5 Billion

The Canadian government has agreed to purchase a next-generation defense radar system from Australia for €1.5 billion, marking a major expansion of bilateral military cooperation between the two nations.

According to official statements from both governments, the deal—announced June 23, 2026—will see Canada acquire the Australian-developed Jindalee Operational Radar Network (JORN) system, a long-range, over-the-horizon radar capable of tracking aircraft, ships, and missiles at ranges exceeding 3,000 kilometers. The purchase underscores deepening defense ties amid rising geopolitical tensions in the Indo-Pacific and Arctic regions.

The radar system, operated by Australia’s Defence Science and Technology Group, has been in development since the 1990s and is currently deployed to monitor air and maritime activity in northern Australia. Canadian officials described the acquisition as "critical to modernizing our early-warning capabilities," with particular emphasis on Arctic sovereignty and North American Aerospace Defense Command (NORAD) operations.

Why is Canada buying Australia’s radar?
The deal follows years of collaboration between the two countries under the Five Eyes intelligence-sharing alliance. Canada’s Chief of Defence Staff, Gen. Wayne Eyre, told reporters the JORN system would "fill a critical gap in our ability to detect and respond to threats in remote regions." The purchase also aligns with Canada’s 2025 Defence Policy Update, which prioritizes Arctic defense and integrated air defense networks.

Australia’s Defence Minister, Richard Marles, framed the sale as part of a broader strategy to "strengthen regional security partnerships." The Australian government has previously stated that the JORN system’s export would be contingent on reciprocal defense cooperation, a condition Canada has now met through joint exercises and intelligence-sharing agreements.

How does this compare to other defense radar deals?
Canada’s €1.5 billion investment dwarfs its 2024 purchase of Patriot missile defense systems from the U.S. (valued at €1.2 billion) and surpasses the €800 million spent on upgrading its CF-18 Hornet fleet. It also outpaces Australia’s own 2023 radar modernization program, which cost AUD 1.1 billion (≈€650 million) for upgraded coastal surveillance systems.

The JORN acquisition is notable for its technological edge: unlike traditional radar, which relies on line-of-sight detection, JORN uses sky-wave propagation to detect targets beyond the horizon, a feature particularly valuable for Arctic monitoring. Canada’s existing North Warning System (NWS), inherited from the U.S., uses older radar technology with limited range.

What are the next steps?
Both governments have confirmed the deal is subject to final contract negotiations, with delivery expected between 2028 and 2030. Canada’s Department of National Defence will integrate the system into its Canadian Forces Integrated Air Defence System (CFIADS), which currently relies on U.S.-supplied sensors.

Critics, including opposition lawmakers in Canada, have raised concerns about cost overruns and potential delays. However, officials from both countries have emphasized the system’s role in countering emerging threats, including hypersonic missiles and Arctic-based adversary activity.

The purchase also signals a shift in Canada’s defense procurement strategy, with fewer reliance on U.S. systems and greater emphasis on allied partnerships. Australia, meanwhile, positions the sale as a test case for its emerging defense export industry, with Marles stating, "This is the first major defense technology transfer to a Five Eyes partner, and we hope to see more in the future."
