초수평선 레이다 캐나다, 호주에서 진달리 초수평선 레이다 구매

캐나다가 호주에서 진달리 초수평선 레이다 네트워크(JORN;  Jindalee Operational Radar Network )를 구매하네요. 마크 카니 캐나다 총리와 앤서니 알바니즈 호주 총리와의 장시간 대화 후 구매결정이 이뤄졌으며, 호주는 미국과 OTH 레이다 네트워크에 대해 협상중이었으나 캐나다가 갑자기 튀어나왔다고 합니다. 계약금액 40억 달러에 이르는 대형 계약이네요. 

이번 계약은 북극 상공의 공중 및 해상 위협을 더 빠르게, 더 멀리서 탐지하고 대응하기 위해서이며, 캐나다의 NORAD 현대화 계획의 핵심 요소라고 합니다. 

BAE가 2028년까지 페이즈 6 업그레이드를 실시중이며, 37,000제곱킬로미터 면적에 걸쳐 최대 3,000km 떨어진 해상 및 공중표적을 감시할 수 있다고 합니다.

This may be "the single biggest defense industry export from Australia in our history. So this is a really, really big opportunity for the nation," Australian Defense Minister Richard Marles said today.

SYDNEY — Australia is poised for its largest defense sale ever, exporting its Jindalee Operational Radar Network (JORN) to Canada, at a cost estimated at more than $6 billion CAN ($4 billion USD).

In a surprise development, Canada’s new prime minister, Mark Carney, spoke with Australian Prime Minister Anthony Albanese overnight and decided to buy the radar, according to government statements. The United States and Australia had been in talks about the over the horizon network, but Canada now appears to have leapt over America’s head, according to the Australian Broadcasting Corporation (ABC), which first reported the story.

“Today, I’m announcing that our government will be working with our long-standing defence and security partner Australia to build a new, long-range, over-the-horizon military radar system,” said Carney. “[It] will enable Canada to detect and respond to both air and maritime threats over our Arctic both faster and from further away. It will most fundamentally keep all Canadians safe.”

An official statement from Carney’s office described JORN as “a key component of Canada’s NORAD modernization plan” to detect and deter threats across the country’s vast northern reaches. “Collaboration with Australia on this critical technology,” the statement says, “will further deepen our long-standing bilateral defense relationship, while supporting Canada’s commitment to strengthening North American defenses in partnership with the United States.”

Albanese confirmed the discussions during a press conference today but did not provide any details.

“There’s a lot of water to go under the bridge here,” Australian Defense Minister Richard Marles told reporters this morning in the northern Queensland city of Cairns, “but in collaborating with Canada in relation to this technology and working closely with them, what is in prospect here is the single biggest defense industry export from Australia in our history. So this is a really, really big opportunity for the nation.”

Marles also said Australia still hopes the United States will purchase JORN technology. BAE Systems Australia is managing a $1.2 billion AUD upgrade to the system, known as the Phase 6 upgrade, which involves hardware and software enhancements as well as sustainment support out to 2028, according to company literature.

JORN monitors sea and air across 37,000 square kilometers, up to 3,000 km away. Unlike traditional radar, which sends a signal and then reads back the return, JORN bounces its signal off the ionosphere, making possible its much greater range.

Jindalee, the system’s original name, is an aboriginal word for a place the eye cannot see.

Notably, Albanese pointed to the importance of Australia diversifying its trade relationships. While he didn’t mention the tariffs President Donald Trump has ordered on Australia, there has been increasing discussion here about the solidity of the alliance and the relationship between the two treaty allies.

“It’s important that we develop that diverse series of relationships and Canada is a very important one, we have so much in common,” he said. Among the things the two countries have in common is that they are treaty allies with the US, have strong economic relationships. Canada, of course, also is feeling tensions with Trump, who has called for it to become America’s 51st state.
