ukQueen Elizabeth & Prince of Wales: the new era of British aircraft carriers
Why are the Queen Elizabeth-class aircraft carriers considered the most important naval project in modern British history? This article explains their design, technology, strategic role, and how these warships redefine the concept of a modern aircraft carrier.
The Strategic Revival of British Carrier Power
In July 2014, the world witnessed the launch of one of the largest warships ever built in Europe — HMS Queen Elizabeth. Together with HMS Prince of Wales, she represents a new chapter in Royal Navy power projection and modern naval engineering.
After the Cold War, the Royal Navy shifted from anti-submarine warfare in the North Atlantic to expeditionary operations. The Falklands War demonstrated that a carrier strike group is essential for global maritime security. Thus, the Queen Elizabeth-class aircraft carrier program was born.
From Cold War Fleet to Global Carrier Strike Capability

During the 1990s, Britain operated smaller light aircraft carriers and numerous anti-submarine destroyers and frigates. However, modern conflicts required flexible sea-based air power. The 2007 decision to build two 65,000–70,000-ton aircraft carriers became a cornerstone of naval modernization.
Technical Design, Capabilities and Operational Role
Design and Engineering: A New Generation Aircraft Carrier

The Queen Elizabeth-class aircraft carriers displace approximately 65,000–70,600 tons at full load. With a length of 280–284 meters and a beam of up to 73 meters, they are the largest warships ever built for the Royal Navy.
A distinctive feature is the ski-jump ramp, enabling short take-off operations for F-35B Lightning II stealth fighters (STOVL — Short Take-Off and Vertical Landing). Two aircraft lifts, each capable of carrying two aircraft, connect the hangar deck (16,000 m²) to the flight deck.
Another innovation is the dual-island superstructure:
- Forward island – ship navigation and command control.
- Aft island – flight operations management.
- This separation increases operational efficiency and survivability.
Power and Propulsion: Advanced Integrated Electric Propulsion
Unlike nuclear-powered U.S. carriers, Britain opted for conventional propulsion due to cost efficiency. The ships use Integrated Electric Propulsion (IEP), powered by:
- 2 × Rolls-Royce Marine Trent MT30 gas turbines
- Diesel generators by Wärtsilä
- 2 × 30 MW electric motors
This system allows speeds exceeding 25 knots and a range of 10,000 nautical miles. The electric architecture enhances automation, reduces crew requirements, and lowers operating costs.
Air Wing and Automation: Efficiency at Sea

Each carrier can operate up to 50 aircraft, including:
- F-35B Lightning II
- Merlin Crowsnest AEW helicopters
- Chinook heavy-lift helicopters
- Wildcat and Apache helicopters
Automation is a defining feature. The advanced ammunition handling system reduces manpower from 200 sailors (traditional carriers) to just 32. The ship’s company consists of about 679 core crew, plus up to 1,600 air personnel during full operations.
The vessels contain 3,000 compartments across 12 decks, medical facilities with operating theatres, gyms, and modern living quarters — demonstrating how naval shipbuilding integrates operational and human factors engineering.

FAQ
Why are Queen Elizabeth-class carriers not nuclear-powered?
Because conventional propulsion reduces construction and maintenance costs while still meeting operational requirements.
What aircraft operate from these carriers?
Primarily F-35B Lightning II stealth fighters and Merlin helicopters.
What makes their design unique?
The dual-island superstructure and integrated electric propulsion system.
How important are these carriers for the UK?
They restore full carrier strike capability and global power projection.
Conclusion
The Queen Elizabeth-class aircraft carriers represent a transformation in British naval strategy. Combining modern shipbuilding technologies, advanced automation, and fifth-generation aircraft integration, these vessels symbolize a return to blue-water naval power.
More than just ships, they are floating airbases — strategic assets shaping maritime security in the 21st century.
