With a displacement of over 65,000 tons, these vessels are the largest warships ever built for the United Kingdom and symbolize the country’s global naval ambitions. The two ships in this class, HMS Queen Elizabeth and HMS Prince of Wales are among the most advanced and powerful carriers in the world today.

This article explores the history, design, capabilities, and operational importance of the Queen Elizabeth-class carriers, emphasizing their role as a critical component of Britain’s naval force projection.

The History Behind the Queen Elizabeth-Class Aircraft Carriers

The journey to create the Queen Elizabeth-class aircraft carriers began in the late 1990s when the UK government recognized the need for a new class of carriers to replace the aging Invincible-class vessels. The British defense strategy was shifting towards expeditionary warfare, and a new generation of carriers was deemed essential to meet the evolving demands of modern warfare.

After years of planning and budget adjustments, the formal contract for two new aircraft carriers was signed in 2008. The first of the two ships, HMS Queen Elizabeth, was launched in 2014, followed by HMS Prince of Wales in 2017. These ships mark the Royal Navy’s return to large aircraft carrier operations, a capability it had not had since the decommissioning of the previous fleet carriers in the 1970s.

Key Design Features of the Queen Elizabeth-Class Carriers

Size and Displacement

The Queen Elizabeth-class carriers are the largest warships ever constructed for the Royal Navy. Each vessel measures around 280 meters in length, with a displacement of approximately 65,000 tons. The sheer size of these ships provides the Royal Navy with an extensive platform for launching and recovering aircraft, accommodating crew members, and housing a range of onboard systems and equipment.

Twin-Island Design

One of the most distinctive features of the Queen Elizabeth-class carriers is their twin-island design. Unlike traditional carriers with a single island (the structure that houses the ship’s bridge and flight control center), these carriers have two islands. One island is dedicated to ship control and navigation, while the other is responsible for air operations. This separation allows for greater flexibility in managing the vessel’s operations and enhances the ship’s ability to function under combat conditions.

Ski-Jump Ramp

Another unique aspect of these carriers is the ski-jump ramp on the flight deck. This feature enables short takeoff and vertical landing (STOVL) aircraft, such as the F-35B Lightning II jets, to launch more efficiently. The ski-jump ramp gives these aircraft the additional lift they need during takeoff, maximizing their payload and fuel capacity.

Aircraft Capacity and Hangar Space

The Queen Elizabeth-class carriers are designed to carry up to 40 aircraft, with the ability to operate a mixture of fixed-wing aircraft and helicopters. The primary aircraft onboard are the F-35B Lightning II jets, which are among the most advanced fighter jets in the world. In addition to these jets, the carriers can operate various types of helicopters, including the Merlin and Chinook.

The ships also feature a large hangar space below deck, capable of storing aircraft when they are not in use or undergoing maintenance. The hangar is equipped with lifts that can move planes between the flight deck and the hangar in a matter of seconds.

Cutting-Edge Technologies and Capabilities

The Queen Elizabeth-class aircraft carriers incorporate state-of-the-art technologies that give them a significant advantage in naval warfare.

Integrated Electric Propulsion System

Both ships are equipped with an Integrated Electric Propulsion (IEP) system, which provides greater efficiency and flexibility in power management. This system uses gas turbines and diesel generators to generate electricity, which is then distributed to the propulsion system and other critical onboard systems. The IEP system reduces fuel consumption and provides the ships with a greater operational range.

Advanced Radar and Sensor Systems

The carriers are outfitted with advanced radar and sensor systems that give them unparalleled situational awareness. The long-range radar can track hundreds of targets simultaneously, while the short-range radar provides detailed information on nearby threats and objects. These systems enhance the ship’s ability to detect and respond to enemy aircraft, missiles, and other threats.

Self-Defense Systems

Although primarily designed to project air power, the Queen Elizabeth-class carriers are also equipped with a robust array of self-defense systems. These include automated close-in weapons systems (CIWS), anti-missile defenses, and decoy systems designed to counter incoming threats such as enemy aircraft, missiles, or small surface vessels.

The Role of F-35B Lightning II Jets

A critical component of the Queen Elizabeth-class carriers is the F-35B Lightning II jets, which form the backbone of the Royal Navy’s air power. These aircraft are designed for short takeoff and vertical landing (STOVL), making them ideal for use on carriers without the need for catapults or arrestor wires.

The F-35B is a fifth-generation multi-role fighter jet, capable of performing a wide range of missions, including air superiority, ground attack, and intelligence, surveillance, and reconnaissance (ISR). Its advanced stealth capabilities, combined with its powerful sensors and weapons systems, make it one of the most formidable combat aircraft in the world.

The Queen Elizabeth-class carriers are built to accommodate up to 36 F-35B jets, enabling them to launch and recover aircraft quickly, ensuring the Royal Navy’s dominance in the air.

Operational Importance and Global Reach

The Queen Elizabeth-class aircraft carriers represent a significant leap in Britain’s naval power projection. These vessels are designed to operate in a wide range of environments, from the cold waters of the North Atlantic to the warm seas of the Indo-Pacific region. Their large size, combined with their impressive range and versatility, allows the UK to respond to global crises and project power far from its shores.

Power Projection and International Partnerships

The Queen Elizabeth-class carriers have already been deployed on various missions, including joint exercises with allied nations such as the United States, France, and Japan. These deployments underscore the importance of the carriers in promoting international security and maintaining the Royal Navy’s influence on the global stage.

The carriers are expected to play a crucial role in NATO operations, as well as in independent British missions. Their ability to carry a variety of aircraft and operate in different environments makes them a flexible and indispensable tool in the UK’s defense strategy.

Humanitarian and Disaster Relief Operations

In addition to their combat capabilities, the Queen Elizabeth-class carriers can also be used in humanitarian and disaster relief operations. Their large size and the ability to transport helicopters and supplies make them ideal for assisting in areas affected by natural disasters or humanitarian crises. The ships’ medical facilities, which include a fully equipped hospital, further enhance their ability to provide aid in emergency situations.

Challenges and Criticisms

Despite their impressive capabilities, the Queen Elizabeth-class carriers have faced several criticisms and challenges. One of the primary concerns is the high cost of building and maintaining these vessels. The total cost of constructing the two carriers is estimated to be over £6 billion, a significant investment for the UK defense budget.

Additionally, there have been concerns about the lack of a catapult launch system on the carriers, which limits them to operating STOVL aircraft like the F-35B. This has led some to argue that the carriers are not as versatile as their American counterparts, which use catapults to launch a wider variety of aircraft.

There have also been debates about the long-term sustainability of the carrier strike group, which includes the escorts, supply ships, and aircraft needed to support the carriers during extended deployments. The high operational costs of maintaining such a group have led to concerns about whether the UK can afford to keep the carriers fully operational over the long term.

Conclusion: Britain’s Naval Giant

The Queen Elizabeth-class aircraft carriers represent a monumental achievement for the Royal Navy and a testament to the UK’s commitment to maintaining a powerful and capable naval force. These ships are designed to project power, provide humanitarian assistance, and ensure the UK’s ability to respond to global threats.

With advanced technology, formidable air power, and a range of operational capabilities, the Queen Elizabeth-class carriers will remain a central part of Britain’s defense strategy for decades to come. Despite the challenges they face, these naval giants symbolize Britain’s return to large-scale carrier operations and its place as a leading maritime power in the 21st century.
