AUKUS Defence Partnership

Rosie Winterton Excerpts

Tuesday 14th March 2023 Commons Chamber

[The Minister for Defence Procurement (Alex Chalk)]

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.

[Alex Chalk]

I thank the right hon. Gentleman for his remarks. He is absolutely right that this is an announcement of such moment that it will require cross-party and generational support. It is important to note precisely the scale of what is being proposed. As he rightly indicated, this is about not simply the sale of a weapons system, but the growth of a capability across continents and across generations. With scale comes opportunity: having that trinational approach builds the resilience of the supply chain and of the industrial capability, which benefits Australia, of course, and the United Kingdom.

The right hon. Gentleman asked about investment. I am pleased to note that, in the last financial year, £2 billion was invested into Barrow-in-Furness and Raynesway, as he will have seen, because I think he has had the opportunity to visit both recently. There will be further investment to come, partly as a result of what has been announced recently, and in the years to come, which echoes my point about it having to be sustained and continued. He is right, of course, to reference the fact that, in the document that accompanies the announcement, a copy of which I am sure he has seen, the Australians have indicated their agreement to make a proportionate investment in UK infrastructure.

The right hon. Gentleman is correct to ask about co-ordination, because this has to be co-ordinated. The way that happens is, first and foremost, to ensure that the Australian experts who need to develop that expertise, as they have candidly acknowledged, spend time in the UK—in Barrow and Raynesway. Indeed, this Thursday, I am looking forward to going to Barrow with the Premier of South Australia, where the first SSN-AUKUS for the Royal Australian Navy will be built.

The right hon. Gentleman raised the issue of AUKUS pillar 2. I have had the opportunity to speak to my opposite number here in the UK to discuss precisely that. There are a number of aspects to it, as he indicated, such as hypersonics, AI and underwater technologies, and further detail will be explored in due course. To his point about other countries, I can say that, unlike pillar 1, which is not open for engagement beyond the three nations, we will of course consider the interest that other nations have expressed in pillar 2.

As is well expressed in the fact sheet that accompanies the announcement, AUKUS—whether pillar 1 or pillar 2—is designed to show:

“our shared commitment to a free and open Indo-Pacific and an international system that respects the rule of law, sovereignty, human rights, and the peaceful resolution of disputes free from coercion.”

That is what our nations stand for, and that is what AUKUS will deliver.

[Madam Deputy Speaker (Dame Rosie Winterton)]

I call the Chair of the Defence Committee.

[Mr Tobias Ellwood (Bournemouth East) (Con)]

As somebody who is passionate about UK security and Britain’s place in the world, I could not hide my deep disappointment yesterday when the new integrated review spelled out a deteriorating global threat picture, but offered no new investment in our conventional forces. We are back here today, however, and I welcome this landmark announcement of ever greater collaboration between three trusted allies. Our political relationship with Washington experienced a bumpy patch post Brexit—I say that as a US-UK dual national—so it is good to see it back where it should be. Indeed, landing AUKUS, the Paris agreement and the Windsor framework shows that statecraft has returned to No. 10.

The procurement programme is for the long term and the first subs will not arrive for another couple of decades, yet the threat picture is deteriorating rapidly. If we are to commit to the Indo-Pacific tilt, does the Minister recognise the urgent need to increase the surface fleet, so that we can meet our responsibilities there?
