With permission, Madam Deputy Speaker, I wish to make a statement about the AUKUS defence partnership. Yesterday, the Prime Minister, standing alongside the President of the United States and the Prime Minister of Australia, announced that our three nations would be jointly developing a conventionally armed—I stress that—nuclear-powered submarine, the SSN-AUKUS, which will come into service in the late 2030s.
Before I provide the House with more details about this landmark announcement, it might be beneficial for colleagues if I provide a brief summary of how we got here. For more than 60 years, the UK and the US have successfully collaborated on the development of nuclear submarines. This unprecedented co-operation goes to the very core of our special relationship. Currently, with the support of the United States, we have a fleet of five Astute-class submarines, with a further two boats to be built. These world-class vessels are an essential component of our defence and security apparatus in a more contested world.
More recently, Australia has also recognised the need for a stealthier and more enduring underwater capability to deter threats to the peace and stability of the Indo-Pacific. That is why back in September 2021, my right hon. Friend the Member for Uxbridge and South Ruislip (Boris Johnson), while Prime Minister, announced to the House a pivotal new defence partnership involving the United States, Australia and the UK, otherwise known as AUKUS. The partnership involves two pillars: first, the joint development of a nuclear-powered, conventionally armed submarine capability for Australia; and secondly, the creation of a suite of complementary technologies, among them hypersonics and cyber. It is the first of those pillars that I wish to focus on today.
For the past 18 months, we have been working closely with our trilateral counterparts to understand Australia’s requirements, to make a detailed technical assessment and to set out the optimal pathway for delivering this unique platform. As the Prime Minister said last night, this scoping period has now concluded and a solution has been identified.
The SSN-AUKUS will be based on the design for the UK’s Astute-class submarine replacement, SSN(R), which has been under development for several years. SSN-AUKUS will build on these firm foundations by incorporating cutting-edge US submarine technology, including the propulsion plant, combat systems and conventional weapons, but this boat will not just be of benefit to the Royal Australian Navy. It is now clear to us that the SSN-AUKUS, which is an evolution of SSN(R), should now become the UK’s future platform as well, providing the future attack submarine requirement for the Royal Navy as well as the Royal Australian Navy.
As yesterday’s refreshed integrated review underlines, we are having to contend with an increasingly volatile and complex environment, with multiple adversaries seeking to undermine our rules-based international order. In response, the deepening of our defence partnership offers three distinct advantages. First, it bolsters our undersea capability. It will give us the ability to deter future threats in the underwater battlespace, to protect our nuclear deterrent and our vital sea lines of communication and to fulfil a range of military tasks, including anti-surface and anti-submarine warfare, land attack and intelligence gathering.
Secondly, AUKUS will bring a truly global and interoperable capability for our nations that is not just capable of operating in the Indo-Pacific, but strengthens our contribution to NATO in Europe. It will enable us to operate in the high north, where the impact of climate change is opening new military and commercial shipping access to the north Atlantic, and it will ensure that three like-minded nations with shared interests on the global stage can work together even more closely.
Thirdly, and finally, AUKUS helps us share the burden of research and development costs, not just giving us access to some of the most advanced technology on the planet, but allowing us to integrate our supply chains and provide greater resilience at a time of growing resource costs and inflationary pressures. It will also open up further opportunities for technology sharing and interoperability across the defence context.
The first SSN-AUKUS for the Royal Navy will be built in the United Kingdom and delivered in the late 2030s, taking full advantage of our many decades of experience in building nuclear-powered submarines. To support SSN-AUKUS, Australia has committed to making a proportionate financial investment in our submarine industrial base. SSN-AUKUS will support thousands of new jobs at Barrow-in-Furness and Derby and throughout the national supply chain. These are truly centres of excellence, and I am proud to say that they stand ready to support Australia in this endeavour. It is particularly good news that Rolls-Royce UK will be building the nuclear reactors for all of Australia’s submarines.
We intend for the first SSN-AUKUS to come into service with the Royal Australian Navy in the 2040s, and Australia will receive substantial support to develop and operate these nuclear-powered submarines. Submariners from the Royal Australian Navy have already begun to train with the Royal Navy to gain the relevant experience and, alongside the US, the Royal Navy intends to increase the number of submarine deployments to Australia from 2026, building on the successful visit to Australia by HMS Astute in 2021. The United States has also signalled her intention to provide Virginia-class attack submarines to the Royal Australian Navy, with Australia planning to acquire three. Taken together, this plan is consistent with Australian sovereignty and international obligations. It systematically and carefully builds Australia’s ability to safely and securely operate, maintain and sustain SSNs.
It goes without saying that compliance with non-proliferation requirements is paramount, and I reassure the House that throughout this process we will remain fully committed to setting the highest non-proliferation standards. We are undertaking every step in a way that reflects our long-standing leadership in global non-proliferation and our steadfast support for the nuclear non-proliferation treaty. We have been clear that we will pursue this endeavour in a way that sets a strong precedent for states seeking to develop a naval nuclear propulsion capability. We have consulted, and we will continue to consult regularly and transparently with the International Atomic Energy Agency with respect to the development of a suitable nuclear safeguards approach. The IAEA director general has expressed his satisfaction with our engagement.
This is a momentous journey for us all. For maritime nations such as the UK, as well as Australia and the US, maintaining a capability advantage over potential adversaries is essential. For the UK, AUKUS represents an historic opportunity for a deep, enduring and mutually beneficial partnership with two of our closest allies—a partnership that will strengthen the resilience of our nuclear submarine enterprise and will bring with it investment and high-skilled, high-wage jobs, as well as an even stronger and more capable Royal Navy submarine force. The United Kingdom will now begin embarking on delivering SSN-AUKUS, along with our allies. I look forward to keeping the House updated on how it progresses. I commend this statement to the House.
