UK’s aircraft carrier returns to sea after major refit

Royal Navy’s aircraft carrier HMS Queen Elizabeth has departed the Rosyth Dockyard following the completion of a significant planned maintenance program, shipbuilder Babcock revealed.

The departure comes after months of detailed engineering work, during which teams conducted extensive inspections, maintenance, and targeted upgrades across the vessel’s critical systems. The work forms part of a scheduled upkeep cycle designed to ensure the carrier remains fully operational and mission-ready amid evolving global security demands.

Phil Craig, Managing Director of Marine Programmes, emphasized the strategic importance of the milestone, noting that the readiness of the UK’s carriers is increasingly vital in a period of heightened geopolitical uncertainty. He said that delivering such a complex programme required both deep technical expertise and close coordination across multiple stakeholders.

The docking marks the fourth time a Queen Elizabeth-class aircraft carrier has undergone dry docking at Rosyth in the past seven years.

With the maintenance phase complete, HMS Queen Elizabeth is expected to begin a series of sea trials in the coming weeks. These trials will test the performance of onboard systems and validate the work carried out before the carrier formally returns to operational service.
