AUKUS | Nuclear-powered Submarines | The Changing Indo-Pacific

Over the past few years, the AUKUS partnership between Australia, the United Kingdom, and the United States has become one of the most significant strategic developments in the Indo-Pacific.

Most public discussion about AUKUS focuses on submarines. That is understandable. The agreement includes a long-term plan for Australia to acquire nuclear-powered submarines and to develop advanced defence technologies with its closest security partners.

But AUKUS is about far more than naval hardware.

It reflects a deeper shift in the strategic balance of the Indo-Pacific region.

Across the Taiwan Strait, tensions continue to simmer. China’s growing military capability and its increasingly assertive posture in surrounding waters have forced governments across the region to reassess long-held assumptions about deterrence and stability.

Strategic planners in Washington, Beijing, Canberra and London all understand a fundamental reality of geopolitics — peace is often preserved not by goodwill alone, but by credible deterrence.

In simple terms, deterrence is about shaping the calculations of others. It seeks to convince potential adversaries that aggressive action is unlikely to succeed.

Submarines have long been central to that calculation.

Nuclear-powered submarines can remain submerged for extended periods, operate quietly across vast distances, and gather intelligence in areas that surface vessels cannot easily reach. In a maritime region as large and complex as the Indo-Pacific, such capabilities matter.

For Australia and its partners, the AUKUS partnership represents a long-term investment in strategic depth. The program will unfold over decades, with the first phase involving the purchase of American Virginia-class submarines before the eventual development of a new SSN-AUKUS class for both the United Kingdom and Australia.

Yet the most interesting aspects of AUKUS may not be the submarines themselves.

They lie in what the partnership represents.

AUKUS signals a growing alignment between democracies concerned about the evolving balance of power in the Indo-Pacific. It also reflects a broader effort to integrate advanced technologies, intelligence capabilities and defence industries in ways that were once considered politically difficult.

In that sense, AUKUS is as much about strategic trust as it is about technology.

It also raises complex questions.

How should nations deter conflict without provoking it?

How should alliances respond to rapid technological change?

And how should democratic societies manage long-term strategic competition while preserving stability?

These are not abstract questions. They shape decisions being made quietly every day in government offices, intelligence agencies and defence headquarters around the world.

They also form the backdrop to my forthcoming novel, No Clean Exit.

The novel explores what happens when institutional strategy and individual vulnerability intersect.

In geopolitical competition, systems are designed to absorb risk. Governments create processes, structures, and safeguards intended to manage uncertainty and prevent small problems from becoming larger crises.

But systems are ultimately operated by people — even in this emerging AI era.

And people bring with them judgement, assumptions, loyalties and, sometimes, blind spots.

We often imagine espionage as dramatic and cinematic — stolen briefcases, secret codes and shadowy figures in dark alleys.

In reality, it is usually much quieter.

It unfolds through conversations, professional relationships, and incremental decisions.

Often nothing seems unusual at the time.

Until it does.

That quieter world — where institutions seek stability while individuals carry the consequences — is the terrain explored in No Clean Exit.
