8th Report - AUKUS
From: Defence Committee
Inquiry: AUKUS
Government response deadline: 28 June 2026
Summary
The Defence Committee examines AUKUS, the trilateral UK-US-Australia defence partnership announced in 2021, assessing progress five years on. The partnership comprises Pillar 1 (nuclear submarine acquisition and SSN-AUKUS development) and Pillar 2 (advanced technologies). While the Committee finds AUKUS's strategic rationale remains sound despite geopolitical shifts, it identifies critical shortcomings: weak political leadership, inadequate public engagement, workforce mobility barriers, industrial capacity gaps, and stalled Pillar 2 progress threaten delivery.
Key findings
- Political leadership in the UK has faded; the Prime Minister must take a more visible role to counter drift that could derail AUKUS, which requires sustained commitment across multiple electoral cycles.
- Public awareness of AUKUS is severely limited; the Ministry of Defence must engage Members of Parliament to communicate benefits at constituency level and build the public support necessary for a programme of this scale and cost.
- Significant barriers to workforce mobility across the trilateral—including security clearances, spousal employment, and tax issues—hamper collaboration and will create bottlenecks as work intensifies; an AUKUS visa should be urgently considered.
- Investment in BAE Systems' Barrow-in-Furness shipyard has already slipped; further delays in upgrading infrastructure and regenerating the submarine industrial base risk SSN-AUKUS delivery and credibility with AUKUS partners.
- Royal Navy infrastructure upgrades at Plymouth and Clyde must be accelerated to relieve pressure from increased SSN visits to Australia; Pillar 2 progress has been inadequate and is losing credibility.
- US Virginia-class submarine production rates are a concern for the three to five boats Australia will acquire before SSN-AUKUS enters service; export control reforms need stronger uptake by UK companies, particularly SMEs.
Recommendations
- Issue a public version of Sir Stephen Lovegrove's AUKUS review as soon as possible.
- The UK Prime Minister must take a more prominent role in driving AUKUS delivery to provide cross-government prioritisation and pace.
- Make the Prime Minister's Special Representative role permanent and ensure it is adequately staffed to exercise its broad remit effectively.
- Advocate for the US and Australia to appoint their own Special Representatives and consider establishing a joint secretariat.
- Set out within six months a clear plan to enable mutual recognition or continuity of security clearances for AUKUS-related work; consider introducing an AUKUS visa.
- Within overarching defence dialogue, enable Members of Parliament to communicate AUKUS benefits and local employment opportunities to constituencies, with MOD adopting a proactive approach to sharing constituency-level data.
- Encourage and incentivise recruitment from geographic locations and demographics without strong defence links, using AUKUS to extend skilled employment across the UK.
- Agree and deliver priority Pillar 2 programmes at pace; place plans to expand Pillar 2 to additional partners on hold until trilateral progress is tangible.

Notable line
“Failure to meet our AUKUS commitments would have severe implications both for the UK's defence and security, and for the UK's standing with its trilateral partners.”

“To lose their clearance and then be required to re-apply for it, is costly for the business; more crucially, it prevents that expert from being professionally useful on their return from supporting an AUKUS partner.”
