"This arrangement demonstrates Australia’s ability to export advanced, high-technology defence systems while safeguarding our national security, and enabling trusted partners to benefit from Australian innovation," said Australia’s defense minister Richard Marles, as Canberra and Ottawa signed a landmark radar deal announced today.
Canada’s $2.5 billion purchase and Canberra’s largest-ever defence export
Australia and Canada have formalized an agreement that will see Ottawa acquire an Over the Horizon Radar (OTHR) system for $2.5 billion (reported as $1.75 billion USD). The contract, announced today, is described by Australian officials as Canberra’s largest-ever defence export and marks the first time Australia has exported its locally developed OTHR, known domestically as the Jindalee Operational Radar Network (JORN).
The transaction explicitly links industrial opportunity and diplomatic ties: Australian leaders framed the sale as reflecting the "close and long-standing friendship" between the two countries, while also highlighting export of a national capability to a trusted partner.
Jindalee Operational Radar Network (JORN): how the system operates
JORN, as deployed in Australia, comprises a control center and three separate radar sites distributed across the country. Each site contains both transmitter and receiver stations. Australia’s Defence Science and Technology Group explains the system’s basic physics: a high-frequency radio signal is sent skywards from a transmitter, refracted down by the ionosphere to illuminate an airborne or seaborne target, and the echo then follows a similar refracted path back to a separate receiver site. The received signal is processed into real-time tracking information.
The system’s design yields long-range, wide-area surveillance: unlike conventional line-of-sight radars, JORN’s ranges are not limited by the curvature of the earth, and the network reportedly provides surveillance at ranges of roughly 1,000 to 3,000 kilometers from Australia.
BAE Systems Australia as the A-OTHR industry partner
BAE Systems Australia will act as the A-OTHR industry partner for the program, the company said in a news release on the Canadian contract. BAE noted it "will support both governments as the A-OTHR industry partner" and pointed to an existing relationship: the firm has been undertaking full lifecycle support of Australia’s JORN and has been carrying out upgrades to the Australian radar network since it was selected for that program in 2018.
Craig Lockhart, Chief Executive Officer of BAE Systems Australia, said Canada’s acquisition represents a "significant opportunity" for industry in both countries and argued the deal positions Australian companies for future exports to allies.
Five Eyes situational awareness and strategic framing
Lockhart linked the acquisition directly to alliance-level benefits, saying Canada’s purchase "supports the strategic interests of both nations through enhanced detection and tracking of threats to North America, strengthening Five-Eyes situational awareness." The original reporting cites that characterization as central to the contract’s strategic rationale: export of JORN-derived capability is presented not only as a commercial transaction but as a contribution to allied surveillance and threat monitoring at extended ranges.
What this means for technologists, procurement leaders, and policymakers
- Technologists and security teams: will be focused on integration and lifecycle support, given BAE Systems Australia’s stated role in full lifecycle support and ongoing upgrades to JORN since 2018.
- Procurement leaders in Canada: will be managing a major purchase that imports a complex national system; the contract’s size and Canberra’s role as original developer set expectations for sustained technical cooperation and upgrade pathways.
- Policymakers in both capitals: have framed the deal as both a diplomatic and a defense-industrial milestone — Marles’ statement emphasizes friendship and safeguarding national security while enabling trusted partners to benefit from Australian innovation.
This deal establishes a clear milestone: the first export of Australia’s JORN capability and, by Australian description, the nation’s largest defence export to date. It binds industrial capacity, long-term support commitments, and alliance-level surveillance objectives into a single package—leaving practical questions about operational integration and the timetable for Canadian deployment to unfold under the terms now agreed between Canberra, Ottawa, and the designated industry partner.
