Canada signed a $2.5 billion agreement with Australia and BAE Systems Australia to acquire an Arctic Over-the-Horizon Radar (A-OTHR) system.
The A-OTHR uses high-frequency radio waves reflected from the ionosphere to detect aircraft and missiles beyond the normal radar range.
The system is based on Australia's Jindalee Operational Radar Network (JORN) technology and supports Canada's North American Aerospace Defence Command (NORAD) modernisation programme.
NORAD (North American Aerospace Defence Command) is a joint defence organisation of Canada and the United States.
The project is expected to achieve initial operational capability by December 2029 and create about 2,270 jobs annually in Canada during 2026–2033.
