House of Lords committee reports UK-Australia submarine partnership agreement
The House of Lords International Agreements Committee has reported the Nuclear-Powered Submarine Partnership and Collaboration Agreement between the UK and Australia for information. The Agreement, laid before Parliament on 1 September 2025 with scrutiny ending 30 October 2025, establishes a bilateral framework for cooperation to design, build and deliver the conventionally-armed nuclear-powered SSN-AUKUS submarine fleet for Australia as part of AUKUS Pillar One. The Agreement will remain in force until 31 December 2075 with reviews every ten years, and amendments will be subject to Constitutional Reform and Governance Act 2010 scrutiny. The Committee noted the Agreement creates contingent liabilities estimated at £3-25m relating to reciprocal indemnities between the parties. The framework covers cooperation in production, operation, sustainment and disposal of SSN-AUKUS vessels, including developing necessary personnel, workforce, infrastructure and regulatory systems.
