Why the AUKUS Alliance Still Matters: Recommitting to U.S., UK, and Australia’s Strategic Pact
The AUKUS security pact, now under review, remains crucial for nuclear submarine cooperation, advanced defense technologies, and deterring China and Russia. Here’s why revitalizing AUKUS is essential for U.S., UK, and Australian security.
Introduction
In September 2021, the AUKUS pact—a trilateral security partnership between Australia, the United Kingdom, and the United States—was launched with the aim of bolstering defense cooperation, enhancing undersea capabilities, and accelerating the adoption of advanced military technologies.
Four years later, under the second Trump administration, the U.S. Department of Defense announced a comprehensive review of the pact, sparking concerns in Canberra, London, and Washington. Allies worry that AUKUS might face downgrading—or worse, abandonment.
But according to senior defense figures, including James Mattis, Gary Roughead, Marise Payne, and Nicholas Carter, AUKUS is not just another alliance: it is a strategic necessity for the decades ahead.
The Strategic Weight of AUKUS
Unlike conventional defense agreements, AUKUS carries two critical pillars:
- Pillar 1: Delivering nuclear-powered submarine capability to Australia, while strengthening U.S. and UK naval capacities.
- Pillar 2: Collaborating on emerging technologies such as hypersonic weapons, cyberwarfare, artificial intelligence, and autonomous systems.
The pact represents more than shared hardware—it formalizes decades of trust and cooperation among three democracies with overlapping security interests.
A Deterrent Beyond the Indo-Pacific
Although AUKUS is often framed as a China-centric initiative, its scope extends beyond the Pacific. Nuclear submarines operating from bases in Western Australia (HMAS Stirling) will reinforce deterrence not only in the South China Sea but also in the Indian Ocean, the Arctic, and the North Atlantic.
By creating interoperability across defense industries and logistics systems, AUKUS offers its members a global deterrence footprint.
Nuclear Submarines: The Backbone of Pillar 1
Australia’s decision to invest in nuclear-powered submarines was transformative. Unlike conventional submarines, nuclear vessels can remain submerged for months, travel at higher speeds, and carry a wider array of weapons systems.
Why HMAS Stirling Matters
Located in Western Australia, HMAS Stirling is being upgraded to serve as a state-of-the-art nuclear submarine base and repair facility. Once complete, it will provide:
- Closer access to key sea lanes such as the Strait of Malacca, vital for global trade and energy flows.
- Maintenance capacity that reduces the tyranny of distance compared to U.S. facilities in Hawaii.
- Extended operational endurance for American, British, and Australian submarines in the Indo-Pacific.
Simply put, this base is a game-changer in naval strategy.
Pillar 2: The Technology Edge
If submarines are the backbone of AUKUS, emerging technologies are its nervous system.
The pact is designed to accelerate collaboration in:
- Undersea warfare systems
- Hypersonic missiles
- Cyber-defense and AI-enabled operations
- Autonomous drones and robotics
Challenges in Pillar 2
Despite progress, Pillar 2 has been criticized as “operationally adrift.” Export controls, bureaucratic inertia, and outdated frameworks like the Missile Technology Control Regime (MTCR) have slowed implementation.
To succeed, AUKUS must:
- Streamline regulations on dual-use technology transfers.
- Provide incentives for small and medium-sized defense firms.
- Establish joint research initiatives with clearly defined priorities.
Why Abandoning AUKUS Would Be a Mistake
Critics argue that nuclear submarines are too expensive and may stretch the U.S. industrial base, which is already under strain. But the long-term benefits outweigh the costs.
- Industrial Base Revitalization: Shared submarine production and maintenance create predictable demand, stabilizing the defense workforce across all three nations.
- Collective Deterrence: A combined fleet of interoperable submarines complicates adversaries’ strategies, from the South China Sea to the Arctic.
- Signal of Reliability: In an era of doubts about U.S. commitments, AUKUS proves that Washington remains a dependable ally.
Abandoning AUKUS, by contrast, would hand China and Russia a strategic win.
China and Russia: Why They Fear AUKUS
Both Beijing and Moscow have voiced strong objections to the pact—and for good reason:
- For China: More capable allied submarines threaten its sea-based nuclear deterrent and expansion in the South China Sea.
- For Russia: Australian nuclear submarines free up U.S. and UK vessels to patrol the Arctic, North Atlantic, and Far East, stretching Russian naval defenses.
In other words, AUKUS directly challenges the military calculus of both rivals.
Reforming the Defense Industrial Base
Over the last three decades, the defense manufacturing sectors of the U.S., UK, and Australia have atrophied. Rising costs, shrinking workforces, and supply chain gaps make it harder to meet modern demands.
AUKUS can act as a forcing function to:
- Build integrated workforces across borders.
- Utilize 3D printing and digital design to reduce repair times.
- Develop a global allied logistics and maintenance network.
This collaborative approach not only lowers costs but also strengthens resilience in the face of prolonged conflicts.
Governance: A Need for Stronger Leadership
Currently, AUKUS oversight sits primarily within defense ministries. But given its wide scope, experts suggest a trilateral secretariat with representatives from defense, foreign, and commerce ministries.
Such a structure would:
- Avoid bureaucratic bottlenecks.
- Ensure alignment on strategic technology priorities.
- Provide authority to compel action when needed.
Without decisive governance, AUKUS risks stagnation.
The Road Ahead
For the Trump administration, the AUKUS review offers an opportunity:
- To streamline U.S. defense processes in line with the “America First” agenda.
- To strengthen a trilateral alliance that directly benefits U.S. strategic interests.
- To demonstrate that Washington can both lead and reform international security partnerships.
As Winston Churchill once said, democracies must “go forward together.” A revitalized AUKUS would embody that principle.

Conclusion
The AUKUS pact is more than a submarine deal—it is a symbol of trust, interoperability, and democratic resilience in an era of rising authoritarian threats.
Canceling or downgrading the agreement would undermine deterrence, weaken industrial bases, and embolden adversaries. Revitalizing it, on the other hand, could shape the security architecture of the 21st century.
For the U.S., UK, and Australia, the choice is clear: AUKUS must not only survive but thrive.
