Australia’s Drone Wake-Up Call: The Lessons Are Already Written

Iran’s drone and missile campaign against the U.S. and U.S. allies has once again focused attention on a stark and uncomfortable reality: the age of autonomous weapons is not a future condition to be planned for. It is the present operational environment.

A recent article in The Australian, drawing on assessments from retired Major General Mick Ryan and former defence official Michael Shoebridge, frames Australia’s current posture in blunt terms. The country lacks layered missile interception, has only limited armed combat drones, and its bases and expensive platforms are largely undefended against the very uncrewed weapons systems now routinely reshaping battlefields from Ukraine to the Red Sea.

What is striking is that this is not a new diagnosis. The lessons have been available, in vivid operational detail, for several years.

My new book, Lessons from the Drone Wars: Maritime Autonomous Systems and Maritime Operations, is in large part an argument that the evidence has been accumulating faster than Western defence institutions and Australia’s in particular have been willing to absorb it. The Iran episode is not a wake-up call so much as the latest in a long series of them. The question is whether this time will be different.

The economic logic at the heart of modern drone warfare is now beyond serious dispute. Defenders in the Middle East have been firing interceptors worth $1.4 million or more to destroy Iranian Shahed drones that cost around $49,000 each. The arithmetic is ruinous at scale.

General Ryan is right to point to Ukraine as the country that has come closest to cracking this problem, shooting down roughly 70 percent of incoming Shaheds with interceptors costing approximately 10 percent of the target’s value. That is a genuine operational achievement, and it was not handed down from headquarters. It was improvised, tested, and refined under fire.

This cost-exchange dynamic is one of the central analytical threads running through my book. What the Ukraine and Red Sea conflicts have demonstrated, at considerable human and financial cost, is that the old model, where technological sophistication translated directly into strategic advantage, has been fundamentally disrupted. A $2,000 drone can threaten a $2 billion destroyer. A swarm of commercial quadcopters can destroy strategic aircraft worth far more than the swarm itself. The decisive variable is no longer which side has the most exquisite platform. It is which side can sustain production, adaptation, and cost-effective attrition over time.

Australia’s defence budget is currently being hollowed out — the mid-year update in December included a $2.6 billion cut over the forward estimates — while the major commitments around AUKUS submarines and Hunter frigates consume most available headroom. These are not trivial investments. They represent important long-term strategic choices.

But they are choices that have crowded out the lower-cost, higher-volume autonomous capabilities that are proving decisive in current conflicts.

The exquisite and the affordable are not alternatives to each other. They must coexist.

That is a core argument of my book, and it is precisely what the current Australian posture fails to deliver.

Ryan’s suggestion about autonomous speedboats — if Australia had half a dozen boat builders on the East Coast producing them at scale, Chinese task forces operating near Australia would have to think very differently — captures this idea precisely. It is not hypothetical. Ukraine demonstrated it against Russia’s Black Sea fleet. The tools exist. The industrial logic is straightforward. What has been missing is the institutional willingness to treat affordable autonomous systems as a genuine strategic priority rather than a complement to conventional procurement.

My book examines this tension through the lens of maritime autonomous systems specifically, and through extensive fieldwork in Australia with both the Australian Defence Force and Australian defence industry. What I found is that the capability and the industrial base are closer to hand than the institutional culture has allowed. Australian companies are already producing leading-edge drone capabilities — as Defence Minister Marles’ office noted, some of these are being deployed in Ukraine — but not to the ADF itself. That is a structural failure of procurement culture, not a failure of Australian industry.

One of the conceptual contributions I offer in the book is the idea of ‘mesh fleets’, the proposition that maritime autonomous systems do not replace capital ships but operate as networked, distributed enablers that extend what those ships can do, fill the gaps where they are absent, and create layered effects that no single platform could achieve alone. This is not a theoretical construct. It is what effective maritime forces are beginning to look like in practice.

The concept of a ‘mission portfolio’ follows from this. Rather than asking what a given platform can do, the relevant question becomes what combination of systems, crewed and uncrewed, surface and subsurface, expendable and reusable, can deliver persistent effects across a defined operational area. Australia’s vast maritime approaches make this framework particularly relevant. No number of frigates or submarines can maintain continuous presence across the nation’s strategic perimeter. Autonomous systems operating in mesh configurations can. The geometry of Australia’s strategic problem is almost tailor-made for this model.

Perhaps the most sobering aspect of the current situation, documented in The Australian and confirmed by everything I encountered in my research, is the adaptation gap. Ukraine scaled drone production from roughly 1,000 units to 4.5 million annually in the space of a few years. Western procurement cycles, including Australia’s, typically run five to ten years for comparable systems. The institutional frameworks designed to ensure accountability and deliver optimised platforms have become barriers to the speed that contemporary conflict demands.

General Ryan’s charge that the government has been ‘asleep at the wheel’ on learning from overseas conflicts is pointed. The government commissioned a lessons-learned process on Ukraine three years into the war. That is not the tempo at which drone warfare evolves. The operational environment is changing in months, sometimes weeks. The OODA loop — observe, orient, decide, act — is not just a tactical concept. It has become a metric of national strategic capacity. Countries that can cycle through it faster than their adversaries accumulate decisive advantages. Countries that cannot, fall behind in ways that are very difficult to recover.

The May budget is a genuine decision point. Opposition defence spokesman James Paterson is correct that the combination of offensive autonomous capabilities and integrated air and missile defence, for northern bases, maritime approaches, and major infrastructure, is exactly where upfront investment is needed. The government’s $10 billion drone and counter-drone commitment is a significant number on paper. What matters is the composition of that spend: how much goes to affordable, scalable, rapidly iterable systems versus how much disappears into extended acquisition processes for platforms that will arrive a decade from now.

The Iranian campaign has illustrated, at real operational cost to others, what happens when the defender runs short of interceptors faster than the attacker runs short of drones. Australia should not need to learn that lesson through its own experience. The data is available. The operational conclusions are clear. What has been lacking is the institutional urgency to act on them.

The title of my book is deliberate. These are lessons from wars that have already happened, not from war games, not from modelling, not from theoretical frameworks. The battlefields of Ukraine and the Red Sea have provided an extraordinary, if terrible, laboratory for understanding how autonomous systems change the character of military operations. The findings are not ambiguous. Cost asymmetry matters more than platform sophistication. Intelligent mass outperforms exquisite scarcity in sustained attrition. Adaptation speed is a strategic variable of the first order. Mesh networks of autonomous systems create operational effects that no capital ship programme can replicate.

Australia is not starting from nothing. The industrial base exists. The research and development capability is real. The ADF has officers and units who understand the operational implications of what they are seeing overseas. What is required is the political and bureaucratic will to translate that understanding into procurement, force design, and doctrinal change at the speed the threat environment demands.

The Iranian drone swarms are not a wake-up call for the future. They are a confirmation of a present that has been visible for years. The question for the May budget and for Australian defence planning more broadly is whether the country will finally act on what the evidence has been showing, or wait for a more direct and costly lesson of its own.

A section of my book on lessons from the drone wars focuses on the Australian case:
