When Sarah Matthews first heard about Australia cancelling its submarine deal with France, she couldn’t understand why her government would scrap billions of dollars in contracts. As a naval engineer working in Adelaide, she worried about her industry’s future. But three years later, watching cranes rise at the site of what will become Australia’s most advanced submarine facility, Sarah finally gets it.
“This isn’t just about submarines,” she tells her colleagues during lunch breaks. “This is about completely changing how we think about defense in the Pacific.” She’s right. What started as a diplomatic crisis has transformed into Australia’s biggest strategic gamble in decades.
The story behind Australia’s nuclear-powered submarines investment reveals how quickly geopolitics can reshape entire industries—and entire nations.
Why Australia Ditched France for Nuclear Power
Back in 2021, Australia made headlines for all the wrong reasons. Prime Minister Scott Morrison’s government abruptly cancelled a $90 billion submarine contract with French company Naval Group. The French were furious. President Emmanuel Macron accused Australia of lying, and France recalled its ambassadors from both Canberra and Washington.

But behind the diplomatic drama was a strategic calculation. Australia realized that conventional diesel-electric submarines wouldn’t cut it in the vast Pacific Ocean. These boats need to surface frequently to recharge their batteries, making them vulnerable to detection.
Nuclear-powered submarines change everything. They can stay underwater for months, travel faster, and cover enormous distances without surfacing. In a region where China’s naval presence keeps growing, that capability matters.
“The French submarines were fine for European waters, but the Pacific is different,” explains Dr. James Mitchell, a defense analyst at the Australian Strategic Policy Institute. “Nuclear propulsion isn’t just about having better submarines—it’s about having submarines that can actually patrol our vast maritime boundaries effectively.”
The AUKUS alliance between Australia, the UK, and the US opened doors that had been locked for decades. Nuclear submarine technology was previously shared only between Washington and London. Now Australia joins that exclusive club.
Breaking Down the $3.9 Billion Investment
Australia just committed $3.9 billion Australian dollars as the first major payment toward its nuclear submarine future. But what exactly does that money buy?
- Purpose-built shipyard construction and design
- Specialized workforce training programs
- Port facility upgrades and security infrastructure
- Nuclear safety and regulatory framework development
- Advanced manufacturing equipment and technology transfer
- Long-term maintenance and support facilities
The investment timeline stretches far into the future. This isn’t a quick purchase—it’s a generational commitment that will reshape Australia’s defense industry.
| Phase | Timeline | Key Milestone |
|---|---|---|
| Initial Investment | 2024-2027 | Shipyard construction begins |
| US Submarine Purchase | Early 2030s | Virginia-class submarines delivered |
| Local Production | 2040s | First Australian-built nuclear submarine |
| Full Capability | 2050s | Complete fleet operational |
“This is the largest peacetime defense investment in Australian history,” notes Professor Lisa Chen, a maritime security expert at Griffith University. “We’re not just buying submarines—we’re building an entirely new industrial ecosystem.”
The government expects the program to create thousands of specialized jobs. Nuclear engineers, advanced manufacturers, submarine technicians, and cybersecurity specialists will all find opportunities in this expanding sector.
What This Means for Everyday Australians
Beyond the strategic implications, this nuclear-powered submarines program will ripple through Australian society in unexpected ways.
Cities like Adelaide and Perth are already seeing increased investment as companies position themselves for submarine-related contracts. Universities are expanding nuclear engineering programs. Technical colleges are developing new training courses.
But the changes go deeper than jobs and education. Australia is fundamentally shifting its strategic posture. For decades, the country relied on distant allies for protection. Now it’s building the capability to project power independently across the Indo-Pacific region.
“My kids are going to grow up in an Australia that thinks differently about security,” says Mark Thompson, a shipbuilder in South Australia. “We’re not just the lucky country anymore—we’re the country that builds some of the world’s most advanced warships.”
The economic impact extends beyond defense. Advanced manufacturing techniques developed for submarines often find civilian applications. Materials science, precision engineering, and automated production systems all benefit from military research and development.
However, challenges remain significant. Australia has no experience with nuclear technology. Building that expertise will take years and require extensive cooperation with American and British partners.
Environmental and safety concerns also persist. While these submarines use nuclear propulsion, they carry conventional weapons. Still, managing nuclear reactors requires unprecedented safety standards and regulatory oversight.
“We’re essentially starting from zero in terms of nuclear expertise,” admits Dr. Rachel Foster, a former Navy officer now working in defense policy. “That’s both exciting and terrifying.”
The regional response has been mixed. Close allies like Japan and India welcome Australia’s increased defense capabilities. China, predictably, opposes the nuclear submarine program and warns about regional arms races.
For ordinary Australians, the program represents both opportunity and uncertainty. Defense jobs typically offer good wages and long-term stability. But the massive financial commitment means fewer resources for other government priorities.
The nuclear-powered submarines program also signals Australia’s acceptance that the strategic environment has changed permanently. The days of relying solely on geographic isolation for security have ended.
FAQs
Why did Australia need nuclear-powered submarines instead of conventional ones?
Nuclear submarines can stay underwater for months, travel faster, and cover vast Pacific distances without surfacing, making them far more effective for Australia’s geographic challenges.
How much will the entire submarine program cost?
The total cost is estimated at over $200 billion Australian dollars spread across several decades, with the initial $3.9 billion being just the first installment.
When will Australia get its first nuclear submarine?
Australia plans to purchase US Virginia-class submarines in the early 2030s, with the first Australian-built nuclear submarine expected in the 2040s.
Will these submarines carry nuclear weapons?
No, the submarines use nuclear propulsion but carry only conventional weapons. Australia maintains its commitment to nuclear non-proliferation.
How will this affect Australia’s relationship with China?
China has criticized the program as destabilizing, but Australia argues it’s necessary for regional security balance as China expands its naval presence.
What jobs will this create for Australians?
The program is expected to create thousands of jobs in nuclear engineering, advanced manufacturing, submarine maintenance, cybersecurity, and related technical fields.
