Financial assistance to Ukraine bill 2024-25
The Financial Assistance to Ukraine Bill will allow the government to contribute to the G7 loan agreement to Ukraine that was agreed in June 2024.
What advanced capabilities are the UK, Australia and the US developing under the AUKUS security partnership?

In September 2021 the UK, Australia and the United States agreed a trilateral defence and security partnership to “help sustain peace and stability in the Indo-Pacific region.”
Known as AUKUS, the agreement reflects the UK’s tilt to the Indo-Pacific, first articulated in the Government’s 2021 Integrated Review of defence, foreign and security policy and reaffirmed in the 2023 refresh of the review.
A major part of the agreement is helping Australia acquire their first conventionally armed, nuclear-powered submarine fleet. This is known as pillar 1 of AUKUS and is discussed in Commons Library paper AUKUS submarine (SSN-A) programme (CBP 9843).
Pillar 2 focuses on developing a range of advanced capabilities, to share technology and increase interoperability between their armed forces. The three countries say one of the aims of AUKUS is to “foster deeper integration of security and defence-related science, technology, industrial bases, and supply chains”.
The Minister responsible for AUKUS Pillar 2 is the Minister for Defence Procurement.
Within pillar 2 are several workstreams covering areas such as artificial intelligence, hypersonic missiles and quantum technologies.
Cyber capabilities
This workstream focuses on strengthening cyber capabilities, including protecting critical communications and operations systems.
Artificial Intelligence and autonomy
The Government says this workstream will provide “critical enablers for future force capabilities”. Early work is focused on “accelerating adoption, and improving the resilience of, autonomous and AI-enabled systems in contested environments.” The UK hosted the first AUKUS AI and autonomy trial in April 2023.
Quantum technologies
The AUKUS Quantum Arrangement (AQuA) will “accelerate investments to deliver generation-after-next quantum capabilities.” The initial focus will be on quantum technologies for positioning, navigation, and timing.
The Conservative Government identified quantum technologies as one of its five “priority technologies of tomorrow” in its National Quantum Strategy in March 2023.
In a July 2023 command paper, the Ministry of Defence said it intends to be “amongst the first militaries to see, and harness, [quantum computing’s] potential in the battlespace.”
A 2017 POSTnote explains what quantum technologies are.
Undersea capabilities
The AUKUS Undersea Robotics Autonomous Systems (AURAS) project focuses on autonomous underwater vehicles.
The Royal Navy is separately working with France to develop a maritime mine counter measures (MMCM) capability which involves unmanned systems operating remotely.
Hypersonic and counter-hypersonic capabilities
The three countries intend to accelerate development of advanced hypersonic and counter-hypersonic capabilities.
A POSTnote looks at hypersonic missile technologies, efforts to develop them, potential applications, and the possible challenges they may represent for missile defence and global stability.
Electronic warfare capabilities
The government says that in an increasingly contested electromagnetic spectrum, this workstream will share “understanding of tools, techniques, and technology to enable our forces to operate in contested and downgraded environments.”
Innovation and information sharing
These two workstreams will look at how they can integrate commercial technologies and learn from each other’s defence innovation enterprises, and expand ways to share sensitive information.
Deep Space Advanced Radar Capability programme
In December 2023 AUKUS leaders announced work on developing a deep space advanced radar capability which will “provide 24-hour continuous, all weather global coverage to detect, track and identify objects in deep space and increase space domain awareness.”
The first radar site will be in Western Australia and is planned to be operational in 2026, with two radar sites in the US and UK “in service by the end of the decade.” Grant Shapps, then Defence Secretary, identified Cawdor Barracks in South-West Wales as the preferred host site in the UK, subject to planning permission.
An early concern about the AUKUS partnership was the extent to which existing US export control laws and regulations might hamper effective technological and industrial cooperation between AUKUS partners.
In August 2024, the government announced a “historic breakthrough” in defence trade by lifting certain export controls and restrictions on technology sharing brought in by all three partners. The UK has issued a new Open General Licence for AUKUS nations which will come into effect on 1 September 2024.
In March 2021 the Conservative Government set out its plan to “tilt” its foreign, defence and security policy towards the Indo-Pacific. The government described the region as “critical to our economy, our security and our global ambition to support open societies” and said it will be “the crucible for many of the most pressing global challenges” in the future. The government reaffirmed its commitment to the Indo-Pacific in its refresh of review in March 2023. Further analysis is available in Commons Library paper The Integrated Review Refresh 2023: What has changed since 2021? CBP 9750.
The Ministry of Defence has described AUKUS pillar 2 projects as capabilities that will “help us to maintain our technological and military edge in an increasingly contested and unstable strategic environment.”
Following the general election in July 2024, the Labour Government announced a new strategic defence review, to be completed in 2025. The terms of reference for the review explicitly said: “the UK is committed to the delivery of the AUKUS partnership with the US and Australia.”
The Foreign Affairs and Defence Select Committees have both suggested expanding AUKUS pillar 2 activities to other countries, notably Canada, Japan, South Korea and New Zealand. While government ministers said they are open to future partnerships, the three AUKUS countries “collectively agree that we are not yet in a position to consider expanding to additional partners.”
This paper discusses some of the capabilities in more detail, as well as discussing the impact of US export regulatory controls and how AUKUS is described in national defence strategies.
