The new US Navy Chief of Naval Operations, Admiral Daryl Caudle, has joined Secretary of the Navy John C Phelan, signalling his intent to overhaul the design of the US Navy and reinvigorate America’s naval shipbuilding base to restore the balance of power.
As Australia continues to grapple with the reality that we will require a larger, more lethal, resilient and adaptable navy, the United States is rapidly seeking to accelerate its efforts to reignite the fires of industry and naval power, to ensure the continued freedom of navigation and access to the global maritime commons.
In the space of a few short weeks, two pivotal speeches have reframed the direction of the United States Navy. Delivered against a backdrop of intensifying strategic competition, industrial fragility and the accelerating transformation of warfare, they underscore a blunt reality: the United States recognises that its naval strength, industrial base and alliances will determine whether it can deter conflict in the years ahead.
This has become increasingly important as the People’s Republic of China’s own naval modernisation and expansion have continued unabated, as has the broader modernisation and expansion of the capabilities of the broad People’s Liberation Army, along with Beijing’s repeated efforts to coerce and dominate the Indo-Pacific incrementally, beginning with the confines of the First Island Chain.
In conjunction with this, the United States Navy and the United States, more broadly, has been stretched thin, as the nation continues to grapple with the very real materiel and personnel costs of the nearly three decades of conflict in the Middle East and ongoing demands from Europe, the Middle East and Indo-Pacific.
For Australia, these developments resonate deeply. As the AUKUS agreement matures, Canberra must grapple with the fact that Washington’s naval renaissance will shape both the tempo of trilateral cooperation and the expectations placed upon allies.
But what exactly was said?
Detroit: Re-industrialising America’s arsenal of democracy
In mid-July 2025, Secretary of the Navy John C Phelan addressed the “Re-Industrialize 2.0” forum in Detroit. His choice of location was deliberate. Detroit symbolises America’s wartime mobilisation during the Second World War, when factories once devoted to cars began producing “trucks, engines, aircraft and machinery that propelled the free world to victory”.
Secretary Phelan urged today’s generation to summon the same spirit of industrial resolve to rebuild the nation’s shipyards and defence production lines. He did not downplay the gravity of the moment, rather echoing the sentiment of our own Deputy Prime Minister and Defence Minister Richard Marles, to state that we face “a world that is more hostile and unpredictable perhaps more so than at any point in my lifetime”.
New technologies in drones, autonomy and artificial intelligence have revolutionised the character of warfare, and adversaries are exploiting them at pace. In such a climate, the ability to adapt and iterate on the battlefield “is no longer just an advantage, it is a key determinant of success”.
Drawing upon the Interim National Defense Strategic Guidance issued by Defence Secretary Pete Hegseth, Secretary Phelan spoke about a bleak strategic landscape: China’s “unmatched military build-up” threatening US and allied security; Russia, Iran, and North Korea stoking regional instability; and the homeland itself newly vulnerable after “years of insecure borders” and evolving missile threats. His prescription was unequivocal: only a combat-credible naval force “ready to fight and win anytime, anywhere, and against any adversary” can guarantee American security.
This leads into the inaugural address of the US Navy’s new Chief of Naval Operations (CNO), Admiral Daryl Caudle, who set the new standard for a new look US Navy.
Washington: Caudle’s first orders as CNO
Six weeks later, ADM Caudle, newly sworn in as Chief of Naval Operations, used his inaugural speech to lay down the Navy’s operational marching orders. If Secretary Phelan’s message was about rebuilding America’s industrial muscle, Caudle’s was about ensuring that muscle could fight.
He promised an updated fleet design, one that will integrate emerging technologies across every domain. His priorities were clear: “Relentlessly pursue full-spectrum readiness while modernising the fleet’s capabilities, scaling readiness capacity and aggressively forging resilient and resourceful sailors.”
Integration across domains, sea, air, undersea, and cyber space would occur “like never before”, with effects synchronised not only across the US joint force but also with allies and partners.
In perhaps his most enduring line, ADM Caudle defined his vision for the future Navy as a force “not only lethal and survivable but also adaptable and sustainable, ready to fight and win for decades to come, securing freedom of navigation and projecting power where and when it matters most”.
Unlike many of his predecessors, ADM Caudle squarely addressed the industrial base’s failings. He set blunt expectations: “Platforms delivered and repaired on time; fully manned and combat-ready ships; ordnance production meeting contracted demand; backlogs in repair parts eliminated; sailors trained to the highest levels of mastery.” This was not rhetoric but a list of operational benchmarks.
Finally, he invoked a principle that resonates strongly in both Washington and Canberra: “Peace through strength works.” With “battle-ready sailors at the helm,” he said, the Navy’s platforms and systems would empower deterrence and, if necessary, deliver decisive force.
A common message: Urgency, strength and adaptability
Taken together, these two speeches provide a unified narrative: the United States is preparing for a prolonged era of competition, one in which industrial capacity and operational innovation are as decisive as firepower itself.
Secretary Phelan’s address recalled the industrial mobilisation of the 1940s, warning that America cannot prevail in future conflicts without revitalising its shipyards, supply chains and defence production. ADM Caudle’s speech extended that logic into operational design, setting expectations for a fleet that is modern, integrated and combat-credible.
Both men framed adaptation as essential. In Secretary Phelan’s words, “adapting and iterating in real time” is the determinant of victory. ADM Caudle echoed the sentiment, insisting the Navy must be simultaneously “lethal, survivable, adaptable and sustainable”.
Implications for Australia and AUKUS
For Australia, these speeches matter for three reasons: industrial expectations, operational integration and strategic burden-sharing.
Secretary Phelan’s demand for reindustrialisation speaks directly to AUKUS. The partnership is not only about submarines, it is also about deepening the industrial and technological base across the alliance. The US is making clear that allies will be expected to contribute.
Australia is already investing in nuclear-powered submarines, shipyard modernisation in Adelaide and Perth, and advanced technology research. Yet if Washington is summoning a Detroit-like mobilisation, Canberra cannot treat its own shipbuilding reforms as optional. The implicit message is that Australia must lift industrial capacity – from building nuclear boats to co-producing munitions and sustaining ships at scale.
ADM Caudle’s emphasis on multi-domain integration “like never before” has immediate consequences for the ADF. The Royal Australian Navy, Air Force and cyber units will need to be able to slot seamlessly into US and allied networks. That requires common platforms, shared doctrine, interoperable data systems and rehearsed command-and-control structures.
The MQ-28 Ghost Bat program, the acquisition of nuclear-powered submarines and joint command initiatives like NORAD-style integrated air defence are all part of this trajectory. But Australia will need to accelerate its digital backbone and ensure that its fleet design aligns with America’s updated architecture.
Finally, both speeches underscore the scale of the challenge posed by China. While Washington affirms its commitment to remain a Pacific power, there is a recognition that allies must shoulder greater responsibility. The phrase “combat-credible naval force ready to fight and win anytime, anywhere” cannot be confined to the US alone – it is a demand that allies like Australia also generate credible combat power.
For Canberra, that means confronting questions about fleet size, strike range and readiness. The Albanese government’s defence policy review has already called for a “focused force” with more long-range strike, but the bar has now been set higher. Under AUKUS, Australia is no longer simply a junior partner, it is an indispensable node in a collective deterrent network.
Key lessons for Canberra
There are a number of key takeaways for Canberra moving forward, particularly as the nation grapples with the ongoing debate at home reinforces that while not alone in confronting a more contested, competitive and potentially hostile region, Australia’s capacity to draw on allies, particularly the United States, will be limited and, accordingly, will necessitate that Australia takes a more direct, considered and committed hand in its own national security.
This is highlighted through a number of key points identified by both Secretary Phelan and ADM Caudle respectively, including:
- Industrial Base as deterrent - Secretary Phelan’s Detroit speech highlighted that deterrence begins long before ships are put to sea. A capable, resilient industrial base signals resolve and provides surge capacity. Australia, often plagued by cost overruns and schedule slips, will need to take this lesson to heart.
- Fleet design for multi-domain war - ADM Caudle’s speech suggests the US Navy will prioritise platforms that can operate in contested electromagnetic environments, integrate unmanned systems, and sustain operations across long ranges. For the Royal Australian Navy, this raises questions about whether the current mix of Hunter Class frigates, nuclear submarines and patrol vessels matches the operational demands of high-end coalition warfare.
- Peace through strength, applied regionally - Perhaps the most striking overlap between both speeches is the embrace of “peace through strength”. For Australia, this underscores the need for a credible deterrent posture in its immediate region. Long-range fires, resilient basing in northern Australia and stronger partnerships with Pacific and Southeast Asian nations will all be required.
The road ahead
Both Secretary Phelan and ADM Caudle have offered a coherent vision: America must rebuild its naval power industrially and operationally to deter great power conflict. Their words will now need to be matched by budgets, shipyard performance and political will.
For Australia, the message is equally clear. AUKUS is not a free ride. It is a joint endeavour requiring industrial mobilisation, operational integration and strategic contribution. If the United States is prepared to reindustrialise Detroit, Canberra must be prepared to reindustrialise Adelaide and Perth.
As ADM Caudle put it, the Navy must be “ready to fight and win for decades to come, securing freedom of navigation and projecting power where and when it matters most”. For Australia, as a trading nation whose prosperity relies on open sea lanes and regional stability, that vision is not abstract. It is a direct statement of national interest.
Final thoughts
The dual messages from Detroit and Washington converge on a single truth: the maritime balance of power is shifting, and the United States and its allies must respond with urgency, resolve and innovation.
From Secretary Phelan’s invocation of Detroit’s wartime legacy to ADM Caudle’s blunt operational demands, the US Navy is signalling that it will no longer tolerate industrial drift or strategic complacency. For Australia, the implications are profound. AUKUS binds the nation’s security to America’s maritime reindustrialisation and demands that Canberra invest in industrial strength, fleet resilience and operational integration.
In this context, the words of both leaders carry weight well beyond America’s shores. Secretary Phelan’s reminder that “adapting and iterating in real time” is essential and ADM Caudle’s insistence that “peace through strength works” are not just slogans, they are imperatives for allies. If Australia wishes to shape its future, it must take them seriously.
