Australia exports Arctic radar capability to Canada

Australia and Canada have signed a major agreement to establish an Arctic over-the-horizon radar capability in Canada, turning one of Australia’s most strategically important surveillance technologies into a substantial defence export programme.

The agreement, valued at around A$2.5bn, will apply Australian high-frequency surveillance expertise to Canada’s northern monitoring requirements. BAE Systems Australia will support the programme as an industry partner, drawing on its role in sustaining and upgrading Australia’s Jindalee Operational Radar Network.

Canada’s Arctic requirement is unusually demanding. Vast territory, sparse infrastructure, harsh weather, long approaches, and growing activity across northern air and maritime routes make conventional line-of-sight sensing insufficient on its own. Over-the-horizon radar uses the ionosphere to detect targets at ranges beyond normal radar horizons, giving defence authorities more warning time across remote approaches.

For Australia, the deal marks a significant export step for a capability that has long been treated as sovereign infrastructure rather than a standard product line. JORN has been shaped by Australian geography, atmospheric science, radio-frequency engineering, signal processing, and long-term sustainment needs. Adapting that experience to Canada requires more than transferring equipment; the system has to be engineered for different ionospheric behaviour, command structures, operating concepts, and North American defence networks.

The industrial work stretches across antenna arrays, transmit and receive sites, high-power RF equipment, computing infrastructure, secure software, signal-processing algorithms, environmental modelling, command integration, training, and sustainment. Site engineering will also be substantial, since Arctic radar infrastructure must function in difficult climates with limited maintenance access.

Canada’s programme will sit within the wider modernisation of northern and continental defence. That introduces interoperability requirements with NORAD architecture, allied sensors, command networks, and air-defence planning. Radar performance alone will not be enough; the system must produce usable track data, connect securely to decision-makers, and remain upgradeable as threats and software methods evolve.

Australia’s industrial role is therefore unusually valuable. The country brings operational experience with a long-range radar architecture that has already been sustained over decades. BAE Systems Australia brings the production and lifecycle bridge between national know-how and deployable infrastructure. Canada brings a strategic surveillance requirement large enough to justify a major build programme.

Strategic sensors are becoming central defence-industrial products rather than supporting accessories. As missile, aircraft, and maritime threats become faster, more dispersed, and more difficult to classify, the ability to detect early and cue response systems becomes a foundation of deterrence. Recent work around mobile IRIS-T SLS air-defence systems shows the demand for more agile interceptors, but those systems depend on sensor networks that can generate credible warning and targeting data.

For suppliers, the contract value is only part of the opportunity. Radar programmes of this type generate long tails of work across civil engineering, RF components, secure computing, software assurance, environmental hardening, technical training, spares, and site support. They also create recurring upgrade cycles as threat libraries, processing methods, and network-integration needs change.

The Arctic setting adds another layer of complexity. Surveillance infrastructure in northern regions must be reliable, maintainable, and resilient without the dense support ecosystem available at more accessible sites. Equipment has to tolerate cold, isolation, power constraints, and difficult logistics. Those pressures turn maintainability and remote diagnostics into core design requirements rather than afterthoughts.

Australia’s success in turning over-the-horizon radar into an export programme may influence how other allied countries think about national sensor technologies. Mature sovereign systems are rarely exportable without adaptation, documentation, supplier maturity, and support structures. Canada’s radar agreement suggests Australia has reached a point where its surveillance expertise can be packaged for allied use without losing the operational depth that made the original system valuable.

For defence manufacturers, the deal underscores a broader procurement shift. The market is not only hungry for ships, aircraft, missiles, and armoured vehicles. It is also investing in the strategic sensing infrastructure required to make those platforms effective. Countries able to industrialise complex detection systems will shape the architecture of allied defence networks well beyond their own borders.
