Royal Navy Queen Elizabeth Class Aircraft Carriers: A Comprehensive Guide

The Queen Elizabeth class aircraft carriers are the largest and most powerful warships ever built for the Royal Navy. Comprising HMS Queen Elizabeth and HMS Prince of Wales, these carriers symbolise Britain’s return to big-deck carrier aviation and provide a cutting-edge platform for global operations.

Designed for flexibility, they are capable of operating both strike fighters and helicopters, ensuring that the United Kingdom maintains a world-class ability to project power at sea.

Origins and Design Development

By the late 1990s it was clear that the Invincible class carriers were approaching the end of their useful service life. Britain required larger, more modern vessels capable of supporting the next generation of aircraft. The Future Carrier (CVF) programme was launched to meet this need, resulting in the Queen Elizabeth class.

Construction began in the 2000s as a joint project involving shipyards across the United Kingdom. The ships are monumental in scale, displacing around 65,000 tonnes and measuring 280 metres in length.

Their through-deck design, large aircraft capacity, and state-of-the-art command and control systems place them among the most advanced carriers in the world.

Fifty-Two Blocks and Six Shipyards

A joint project involving shipyards across the United Kingdom is putting it mildly. No single British yard could build a 65,000-tonne ship any more, so each carrier was assembled from fifty-two separate blocks, built in six different shipyards around the country and floated to Rosyth to be put together. The pair came in at a total programme cost of about 6.1 billion pounds.

The Two Years Spent Deciding How the Aircraft Would Land

There is an episode in the middle of the programme that deserves telling, because it cost a great deal and produced nothing at all. The 2010 defence review ordered that one ship be converted to catapults and arrestor wires, so that she could fly the F-35C, a conventional carrier aircraft with considerably longer range than the short take-off F-35B.

On paper it was the better aircraft and the better ship. An eighteen-month study then watched the conversion cost climb from about 886 million pounds a ship in late 2010 to two billion and still rising by early 2012, with roughly three more years added to the build, which would have left Britain without a usable carrier well into the 2020s. In May 2012 Philip Hammond reversed the decision and went back to the ski jump and the F-35B.

The study and the reversal together cost something in the order of a hundred million pounds, spent examining a change that was never made. It is worth knowing when reading about the ski jump, because the ramp on the bow is not simply a design preference. It is the outcome of an argument that ran for two years and was settled by arithmetic.

Ships of the Class

Two ships make up the class:

HMS Queen Elizabeth (R08)

HMS Prince of Wales (R09)

Both were built to identical designs, though their deployment patterns and operational roles vary.

HMS Queen Elizabeth (R08)

HMS Queen Elizabeth was commissioned in 2017 as the lead ship of the class. She conducted her first sea trials in 2017 and was formally declared operational in 2020.

She embarked F-35B Lightning II stealth fighters for the first time during trials in the United States, marking a significant milestone for the Royal Navy. In 2021, she deployed on her maiden operational tour, Carrier Strike Group 21, which sailed to the Indo-Pacific alongside allied navies.

This deployment demonstrated the global reach of Britain’s new flagship.

HMS Queen Elizabeth continues to serve as the cornerstone of the Royal Navy’s carrier strike capability, regularly conducting exercises with NATO partners.

Queen Elizabeth's First Major Refit

HMS Queen Elizabeth (R08) has since been through her own first major refit, begun in November 2024 and including eight months in dry dock at Rosyth. She sailed from Portsmouth on 5 September 2026 for a three-month deployment around the United Kingdom and northern Europe as a NATO command ship.

HMS Prince of Wales (R09)

Commissioned in 2019, HMS Prince of Wales is the second ship of the class. Like her sister, she operates both fixed-wing aircraft and helicopters, offering flexibility across strike, anti-submarine and amphibious operations.

She has participated in NATO exercises and served as the Royal Navy's NATO flagship, and in 2025 she led Carrier Strike Group 25 on an eight-month deployment to the Indo-Pacific. While her early years saw some technical challenges, she remains central to Britain’s long-term carrier strike force and complements HMS Queen Elizabeth by ensuring at least one ship of the class can be operational at any time.

The Shaft, and What Was Actually Wrong With It

Some technical challenges is doing an enormous amount of work in that sentence. In August 2022, two days out of Portsmouth and bound for the United States, the coupling connecting Prince of Wales's starboard propeller shaft to its drive shaft failed off the Isle of Wight, damaging both shaft and propeller and ending the deployment before it began.

The investigation found something worse than bad luck. The shaft had been misaligned when she was built, and several components had been incorrectly installed. Repairs at Rosyth took nine months and something in the region of twenty-five million pounds, and she did not go back to sea until 21 July 2023.

Carrier Strike Group 25, and the Deployment That Proved It

The 2021 deployment showed that the ships worked. The 2025 one showed what they were for, and it was HMS Prince of Wales (R09) who took it. She left Portsmouth on 22 April 2025 and came home on 30 November, and the numbers behind Operation Highmast are worth setting out.

Two hundred and twenty-three days. More than forty thousand nautical miles, over half of it east of Suez. Warships and support vessels from ten nations in company, and work with more than thirty. Her aircraft, helicopters and uncrewed machines flew more than 2,500 sorties.

And on 21 November 2025, in the last fortnight of it, the UK Carrier Strike Group was declared at Full Operating Capability, with twenty-four F-35Bs embarked, flown by 617 Squadron of the Royal Air Force and 809 Naval Air Squadron. That is the largest fifth-generation air wing the Royal Navy has put to sea, and reaching it is the point of the whole enterprise: a carrier without a full air group is a very large ship with a flat roof.

It is worth being fair about what followed. The ship that broke down two days into a deployment in 2022 is the ship that led a 223-day Indo-Pacific deployment in 2025 and brought the whole strike group to full operating capability. Both things are true, and the second is the more important.

Technical Features

The Queen Elizabeth class incorporates advanced technology and design features that make them the most capable ships ever to serve in the Royal Navy:

Displacement: 65,000 tonnes full load.

Length: 280 metres (920 feet).

Propulsion: Integrated electric propulsion system with gas turbines and diesel generators.

Speed: In excess of 25 knots.

Flight Deck: A vast through-deck design with a ski-jump ramp for operating V/STOL aircraft.

Aircraft Capacity: Up to 36 F-35B fighters plus 14 helicopters, with flexibility depending on mission requirements.

Crew: Around 700, increasing to 1,600 with embarked air group.

Command Facilities: Equipped with one of the most advanced maritime command and control systems in the world.

These carriers are built to support not only strike operations but also amphibious assaults, humanitarian aid and disaster relief, making them among the most versatile warships afloat.

Operational Role and Strategic Importance

The Queen Elizabeth class marks the United Kingdom’s return to true carrier strike capability after nearly a decade without fixed-wing carriers. They provide the flexibility to project air power globally, support NATO and coalition operations, and serve as a deterrent to potential adversaries.

Their ability to operate the fifth-generation F-35B Lightning II places them at the forefront of modern naval aviation. Beyond combat roles, they are equally suited to humanitarian and disaster relief missions, reflecting their adaptability.

With two ships in service, the Royal Navy can maintain continuous carrier strike availability, a critical factor in sustaining Britain’s global presence.

That is the intention rather than a guarantee, and it is worth saying plainly. Two hulls do not reliably produce one available: a carrier spends long periods in refit, and when one is in dock any problem in the other leaves the Royal Navy with no carrier at all for a while. It happened in 2022, and again in 2024 when Queen Elizabeth handed a NATO exercise to her sister over a coupling problem of her own.

The same arithmetic caught the Invincible class before them and the amphibious ships after them. Two of anything is the minimum a navy can order and still claim a continuous capability, and it works only when nothing goes wrong.

Queen Elizabeth Back at Sea, 2026

On 5 September 2026, with Prince of Wales in maintenance at Portsmouth after the first phase of Operation Firecrest, HMS Queen Elizabeth sailed for a three-month deployment around the UK and northern Europe as command ship of NATO's Allied Response Force (Maritime), the first time a ship of the class has held that role. The training programme she began that autumn is intended to prepare her to take over from her sister as the UK's flagship and high-readiness strike carrier in late 2027, exactly the kind of handover the two-ship arrangement depends on.

The Largest Ships Britain Has Ever Sent to Sea

The Queen Elizabeth class aircraft carriers represent the future of British maritime power. As the largest warships ever built for the Royal Navy, they embody cutting-edge technology, flexibility and strength.

With their combination of F-35B fighters, helicopters, advanced sensors and command facilities, they ensure Britain remains a leading naval power in the twenty-first century.

The carriers have already proven their worth in global operations, and as they mature into full service they will shape the Royal Navy’s role for decades to come.
