Why Canada Turned to Australia for Arctic Surveillance

In today’s episode of the Expert Series, Dr. Thomas Hughes, Dr. Andrea Charron, and Dr. Malcolm Davis examine Canada’s landmark $2.5 billion bilateral agreement to adapt Australia’s proven Jindalee Operational Radar Network (JORN) for its own Arctic Over-the-Horizon Radar (A-OTHR) system. They discuss the technical parameters of over-the-horizon radar compared to traditional line-of-sight systems, the unique scientific, logistical, and environmental challenges of adapting Southern Hemisphere sensor architectures to polar latitudes, the industrial and strategic dynamics of the bilateral alliance, and how the new sensors must eventually integrate into a broader, multi-layered "system of systems"—including space-based satellites, maritime sensors, and F-35 fighter fleets—to deliver a fully responsive and modernized NORAD command and control structure.
