Babcock has returned HMS Queen Elizabeth, the Royal Navy’s flagship aircraft carrier, to operational readiness following completion of a planned maintenance programme at its Rosyth site.
Announced on 22 April 2026, the work involved thousands of hours of engineering activity covering inspection, maintenance and enhancement of the ship’s critical systems, including propulsion, stabilisation and wider repair and renewal. The ship will now begin a period of sea trials before returning to front-line duties with the Royal Navy, contributing to the United Kingdom’s ability to project maritime power and respond to global requirements.
The maintenance period was delivered by Babcock’s workforce of engineers, technicians and project specialists at Rosyth, one of the largest waterside manufacturing and repair facilities in the United Kingdom. It represents the fourth successful Queen Elizabeth-class aircraft carrier dry docking undertaken at Rosyth in seven years, confirming the site’s position as the sustained home of United Kingdom carrier refit activity. At 65,000 tonnes, HMS Queen Elizabeth and her sister ship HMS Prince of Wales are the largest and most complex warships ever operated by the Royal Navy.
Phil Craig, Babcock’s Managing Director of Marine Programmes, said the work ensures that the carrier continues to meet the operational demands placed upon her. At a time of increasing global uncertainty, Craig said, the availability and capability of the United Kingdom’s aircraft carriers is more important than ever, and the milestone reflects both the strength of collaboration and the depth of expertise required to sustain the Royal Navy’s most complex warships. Sustaining this level of capability, Babcock added, supports high-value jobs and helps maintain the specialist skills needed to keep the United Kingdom’s fleet operational.
The milestone sits within a broader picture of sustained back-line naval activity in the United Kingdom. Babcock’s Rosyth yard supports wider Royal Navy sustainment programmes including the Future Maritime Support Programme, whose extension to October 2028 was confirmed in Parliament on 16 April, and forms part of the maritime industrial base that will transition into the Naval Support Integrated Global Network. The carrier refit programme is, in turn, a direct driver of demand across UK sub-systems, with work across propulsion, stabilisation, electrical distribution, habitability and safety-critical systems flowing through Tier 2 and Tier 3 supplier networks.
For suppliers, the Rosyth programme offers a clear reference point for positioning against carrier and wider Royal Navy sustainment opportunities. Relevant capability areas include gas turbine and propulsion systems support, stabilisation and steering gear, electrical and mechanical refit, non-destructive test and inspection, coatings, scaffolding and access, fire safety, heating ventilation and air conditioning, and logistics and spares provisioning. Companies should engage Babcock Marine Programmes through its supplier routes and track Rosyth-aligned opportunities as HMS Queen Elizabeth progresses through sea trials and HMS Prince of Wales’s future refit cycle is planned.
