MELBOURNE — The governments of Australia and Canada have signed an agreement for the Ottawa to purchase an Over the Horizon Radar (OTHR) system for $2.5 billion ($1.75 billion USD) — marking Canberra’s largest-ever defense export.

The contract, announced today, also marks the first time Australia has exported its locally developed OTHR system, which is known here as the Jindalee Operational Radar Network (JORN).

Australia’s defense minister, Richard Marles, said that the deal reflected the “close and long-standing friendship” between both countries.

“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,” he said in a press release.
