COLUMN: AUKUS and Its Swarm Drones — The Silent Response Beijing Hears Loud and Clear

June 22, 2026 on Salisbury Plain: an experiment in future warfare

On June 22, 2026, under near-constant rain in the difficult woods of Salisbury Plain in England, Australian, British, and American soldiers flew up to six drones simultaneously as part of the Army Warfighting Experiment 2026. These drones carried no bombs — they searched for targets, shared their data in real time through a common command hub, and tested artificial intelligence algorithms capable of recognizing and confirming targets in complex forested environments.

It was not the most spectacular military exercise of the year. There were no tanks or aircraft carriers. Just soldiers with tablets and drones in the woods. But in the logic of global strategic competition, this discreet exercise sends a message that Beijing receives with perfect clarity: the democracies of AUKUS are quietly building the next generation of warfare.

AUKUS Pillar II: the technologies that frighten Beijing

AUKUS — the trilateral alliance between Australia, the United Kingdom, and the United States — rests on two pillars. Pillar I, the most publicized, concerns the nuclear-powered submarines that Australia will receive from its partners. Pillar II, less visible but equally important, covers advanced military technologies: autonomous systems, artificial intelligence, hypersonic weapons, underwater capabilities. The Salisbury tests fall under Pillar II — and it is precisely this pillar that matters most to the military planners thinking through a potential conflict in the South China Sea.

AUKUS has been criticized since its creation in 2021 for promising too much, delivering too slowly, and talking more than it acted. These swarm drone tests do not refute all of those criticisms — but they show that Pillar II is producing concrete results. And concrete results, in matters of deterrence, are worth more than the best speeches.

From two drones to six: expanding the coverage

During the Salisbury exercises, operators progressed from a configuration of two drones to one of six simultaneous drones. Corporal Kai Smith, a drone operator with the 1st Armoured Regiment of the Australian Army, described the basic mechanics: "the drones would go to a location, use swarming software to break down the sector, conduct their scan and send images back to the end user's device."

This understated description conceals significant sophistication. A drone swarm does more than multiply sensors — it creates collective intelligence. Each drone shares its data with the others and with the human commander. The system can be programmed to automatically allocate search zones, to prioritize targets according to pre-defined criteria, to distinguish a civilian vehicle from a military one. This is what military planners call "enhanced target recognition" — one of the most sought-after advantages in modern warfare.

Interoperability: the real revolution of AUKUS

Hing-Wah Kwok, an engineer from DSTG (Australia's Defence Science and Technology Group) embedded in the exercise, articulated what gives these tests their true added value: "Being able to refine and retrain models in the field and rapidly exchange them between AUKUS partners through common standards is a true force multiplier. It allows AUKUS partners to leverage each country's models, building capabilities beyond what any single country could achieve alone."

This point is crucial: the value of AUKUS lies not just in any single country's capabilities, but in their interoperability. An Australian drone trained to recognize targets in specific environments can share its AI models with its British and American partners in real time. This technological integration creates a force whose sum exceeds its parts — and that is precisely what Beijing cannot easily replicate with its own partners, whose technical architectures are less compatible.

Interoperability of military AI systems — this is an area where the West has a genuine lead. China produces many drones, fast, but its systems are designed to operate within a centralized architecture, not a distributed network interoperable with allies. This architectural difference is a strategic advantage that must be preserved and deepened.

Drone swarms as a response to Chinese quantitative supremacy

China is building its military advantage in the South China Sea and the East China Sea on quantity: more ships, more aircraft, more missiles. Faced with this numerical superiority, the democracies of AUKUS and their allies cannot simply replicate by building faster. They must find technological asymmetries that compensate.

Drone swarms are one of those asymmetries. They allow a numerically inferior force to cover a much larger air and maritime space, to saturate enemy defenses, and to operate in "contested" environments where conventional aircraft would be vulnerable. Colonel Jake Penley, who oversees these experiments, put it directly: "Autonomous systems are no longer experimental. They are moving to the core of how land forces operate, particularly in contested environments."

The South China Sea: the imagined theatre behind the English woods

When the soldiers of Salisbury were flying their drones through the difficult woods in the rain, the tactical scenario they were testing was not abstract. The "contested environments" that Western military planners speak of are notably the artificial islands and reefs built by China in the South China Sea — fortified installations equipped with missiles, electronic warfare systems, and radar capabilities. Any conflict scenario in that region would require intensive prior reconnaissance in environments hostile to conventional aircraft.

China has not ignored the AUKUS exercises. China's Foreign Ministry has regularly condemned the partnership as "provocative" and "likely to trigger a regional arms race." Those protests are precisely the sign that the signal is being received. When Beijing shouts, it is often because it hears something that concerns it.

There is something deliberately discreet about the way AUKUS communicates its technological advances. No spectacle is made of it. It tests, refines, and shares in silence. That is a form of strategic sophistication: not provoking Beijing unnecessarily while still sending the message that the capability exists and is progressing.

The first signature project: underwater drones

On the sidelines of the Shangri-La Dialogue in June 2026, the Defence Ministers of the three AUKUS countries announced the first "signature project" of Pillar II: the development of underwater drones equipped with advanced sensors and weapons systems to detect, deter, and neutralize underwater threats, notably against undersea cables and pipelines. The United Kingdom committed an initial contribution of £150 million sterling (approximately $200 million) to this program.

This project directly targets a vulnerability identified by the allies: undersea telecommunications cables and energy pipelines are critical infrastructure whose protection is becoming a strategic priority. Recent incidents, notably in the Baltic Sea, have shown that this infrastructure can be sabotaged. The AUKUS underwater drones will be deployed to monitor and protect these networks.

AI algorithms deployed aboard an Australian P-8A

Another discreet but significant advance mentioned during the Australia-UK Ministerial Consultations (AUKMIN) on June 10, 2026: AUKUS-designed AI algorithms were for the first time deployed aboard an Australian P-8A maritime patrol aircraft, enabling faster processing of sonar data from acoustic buoys from all three nations. This real-time integration of underwater surveillance data represents a qualitative leap in the capacity to detect enemy submarines — notably Chinese ones — in the Indo-Pacific region.

These developments do not make front pages. But they accumulate, brick by brick, a technological lead in domains — submarine, autonomous systems, AI — where China is investing massively to catch the West. The race is real. It is being run in English woods, on Australian coastlines, in laboratories that issue no press releases.

I remember analysts who, in 2021, said AUKUS was mostly symbolic and that nothing concrete would emerge for decades. Three years later, AUKUS algorithms are running in Australian aircraft on active operations, and drone swarms are being tested in real conditions in England. Reality has overtaken the skeptics.

The submarine question: Pillar I's Achilles' heel

While Pillar II is advancing, Pillar I — the nuclear-powered submarines — remains much slower and more problematic. Australian analysts are publicly questioning AUKUS's ability to keep pace with the rapidly expanding Chinese submarine fleet. An Australian Sky News program in June 2026 cited concerns that the future AUKUS submarines "may not be able to keep pace" with the Chinese fleet, whose quality and quantity are increasing simultaneously.

This concern is legitimate. The first Australian AUKUS submarine will not arrive until the 2030s. China will build dozens of submarines in that interval. The AUKUS response to this challenge — more underwater drones, more distributed sensors, a denser surveillance architecture — is sensible, but it does not fully replace the firepower of submarines.

Beijing counter-maneuvering

China is not passively watching the development of AUKUS capabilities. It is itself investing massively in drone swarms, autonomous systems, and anti-access/area-denial capabilities. Its comparative advantage is production speed and quantity. Chinese drones are individually less sophisticated — but in sufficient numbers, they can saturate enemy defenses.

The Salisbury exercises tested a swarm of six drones. China has demonstrated swarms of several hundred units in military exhibitions. The quantitative gap is real. The AUKUS response bets on quality, interoperability, and continuous innovation rather than mass. That is a coherent strategy — but one that demands sustained and continuous investment that democracies must maintain despite the potential fatigue of their publics.

The quantitative comparison of China versus AUKUS on drones concerns me. But the real question is not how many drones each side possesses — it is who can operate, train, and maintain them most effectively under real combat conditions. On that terrain, exercises like Salisbury have a value that raw numbers cannot capture.

Autonomous target recognition: the technological leap

The AUKUS exercise on Salisbury Plain was not simply a remote-piloting exercise. The key test concerned the ability of drones to identify, classify, and engage targets autonomously, with minimal human supervision. According to the communiqué from the Australian Department of Defence, the AI algorithms used integrated modules developed under the P-8A AUKUS AI program — a joint signal-processing and image-recognition project that exploits data collected by maritime patrol aircraft.

This level of autonomy raises legal and ethical questions that the three governments prefer to keep in the shadows for now. The Geneva Conventions and UN discussions on LAWS (Lethal Autonomous Weapons Systems) have still not produced a binding treaty. In the meantime, the democracies developing these capabilities advance in a relative legal vacuum — granting themselves decisive operational advantages while carefully avoiding naming them for what they are: semi-autonomous killing machines.

The difference between a drone and a swarm

A single drone is an intelligence platform or a guided weapon. A swarm of six drones or more coordinated by AI is a systemic weapon of a different nature: it can saturate enemy counter-drone defenses, cover far larger geographic areas, maintain continuous surveillance without interruption for recharging, and adapt its formation in real time to enemy countermeasures. The Ukrainian lesson is clear: anti-drone defenses such as Gepard systems or American Counter-UAS systems can shoot down individual drones. They are quickly overwhelmed against a coordinated swarm.

AUKUS is here testing a response to the drone swarm doctrine that Russia and especially China are actively developing. The PLA (People's Liberation Army) has showcased swarms of 200 to 1,000 drones in publicized exercises. The six drones of Salisbury are a starting point, not a final answer. But the inter-allied coordination framework established — with Australia, the United Kingdom, and the United States sharing the same algorithms and the same command protocols — is the true strategic asset that no camera filmed.

Six drones above Salisbury today. Perhaps six hundred above the Taiwan Strait in ten years. The technological trajectory is clear; the political question of if — and how — to use it is far less so. And that is what should keep us awake.

Australian nuclear submarines: timeline and realities

While drones made headlines at Salisbury, the true core of AUKUS continued advancing quietly: the transfer to Australia of conventional nuclear submarine capability (CONV-NUKE). According to the joint Australia-United Kingdom communiqué of June 22, 2026, the first Virginia-class submarine under the Australian flag should be operational by 2032, with a permanent naval base at HMAS Stirling near Perth, in Western Australia.

This timeline is tight but credible according to naval experts. The US Navy has agreed to temporarily reduce its own orders for Virginia-class submarines to allow delivery of the first Australian examples, a significant political concession in a context where American shipyards are themselves under pressure. In parallel, the AUKUS Underwater Drone program funded at £150 million by the United Kingdom is developing autonomous underwater drones capable of patrolling the approaches to the South China Sea without exposing human crews.

Why Perth and not Sydney: the strategic geography of AUKUS

The choice of Perth as the operational base is not incidental: it is the Australian city closest to the Indian Ocean and the straits of Malacca and Sunda, mandatory transit points for maritime trade between Asia and Europe. A submarine fleet based in Perth can monitor and, if necessary, deny those routes far more effectively than a fleet based on the eastern Australian coast. That is a geostrategic lesson the Royal Australian Navy did not need to relearn — the Second World War had already proven the critical importance of those straits.

For China, this projection of Australian submarine power is a direct threat to its String of Pearls strategy — its network of maritime bases and influence extending from the South China Sea to the Indian Ocean. Beijing has labeled the AUKUS agreement a "Cold War mentality" and a "violation of non-proliferation obligations." These are accusations that Washington, Canberra, and London firmly reject — but they reveal the intensity of Chinese anxiety in the face of this new strategic reality.

We build submarines in Perth to monitor straits that most Westerners cannot even name. That is real geopolitics: not summit speeches, but tempered submarine steel slipping silently through waters no one sees.

Southeast Asia caught between two fires

While AUKUS sends a strong signal to Beijing, it also generates deep ambivalence among the countries of ASEAN (Association of Southeast Asian Nations). Major trading partners of China such as Indonesia, Malaysia, and Vietnam fear being forced to choose sides in a Sino-American confrontation they do not want. Indonesia officially protested AUKUS upon its announcement in 2021, expressing concern about a nuclear arms race in the region. Those reservations have not disappeared in 2026.

The AUKUS strategy bets on the clarity of the signal to Beijing while hoping that Southeast Asian countries will understand that their own security depends on a balance of power that prevents China from unilaterally dominating the region. That bet is not yet won. Several regional capitals — Bangkok, Kuala Lumpur, Jakarta — continue to believe that the best strategy is a careful equidistance between the two superpowers, which Westerners sometimes call "active neutrality."

What AUKUS cannot replace: American diplomatic presence

The submarines and drones of AUKUS cannot replace American diplomatic and economic presence in Asia, which the Trump administration has significantly reduced since 2025. The American withdrawal from CPTPP (Trans-Pacific Partnership), trade tensions with several ASEAN members, the reduction of USAID funding in the region — all of this erodes American influence in ways that joint military exercises cannot easily compensate.

Beijing is not merely building missiles and destroyers: it is financing ports, roads, universities, and hospitals throughout the region. The competition with China is therefore simultaneously military, economic, technological, and soft power. AUKUS responds effectively to the military dimension — it leaves the other three dimensions insufficiently covered. And in the long game being played for influence over 21st-century Asia, ignoring those dimensions would be a major strategic error.

You can have the best drones in the world and the most silent submarines in naval history — if you no longer have ambassadors in regional capitals, if you cut development aid, if you wage trade wars against potential allies, you still lose. Soft power remains irreplaceable, even in the age of swarms.

Deterrence that does not speak loudly

What strikes me about the AUKUS exercises at Salisbury is their deliberate discretion. No flashy press conference. No spectacular videos posted on social media. A factual communiqué, a few quotes from soldiers and engineers, and that is it. It is the opposite of Chinese or North Korean strategic communication, which loves grand parades and launches filmed from every angle.

That discretion is itself a strategic choice. The AUKUS democracies do not need to provoke Beijing — they need to deter it. Deterrence works when the adversary knows you have the capabilities, without knowing exactly which ones and where. The Salisbury exercises serve that function: they exist, they are known, but their technical details remain in the shadows.

A message Beijing hears loud and clear

China follows very closely the technological developments of its potential adversaries. It knows what AUKUS is testing. It knows what AI interoperability between Australia, the United Kingdom, and the United States means in terms of command resilience under combat conditions. It knows that the next generation of warfare is being decided in algorithms and autonomous swarms, not just in aircraft carriers and missiles.

The Salisbury exercises send a simple but powerful signal to Beijing: the democracies are adapting. They are learning. They are integrating the lessons of the war in Ukraine and recent conflicts in the Gulf. And they are doing it together, with an interoperability that authoritarian systems cannot easily replicate. That is the real answer to Chinese expansionism — not a loud answer, but a deep one.

AUKUS may be the most important defensive partnership of the 21st century. Not because it is the strongest — but because it is the most carefully thought through. It marries cutting-edge technology, shared history, and political will in a coherent architecture. If the democracies hold the course, if they do not let themselves be divided by trade disputes or social media storms, this discreet signal sent from Salisbury will resonate for a long time.
