Introduction
An aircraft carrier is often described as a βcity at seaβ and a βfloating airbase.β It is one of the most powerful and complex naval vessels ever built, serving as a symbol of military strength and strategic influence. These massive warships enable a nation to project air power across the globe without relying on local bases, making them a critical component of modern naval warfare.
Aircraft carriers are warships equipped with full-length flight decks, enabling them to deploy, recover, and support aircraft at sea. They serve as floating airbases and are pivotal for naval power projectionβespecially for nations lacking nearby military airfields.
History and Evolution
The concept of the aircraft carrier emerged in the early 20th century. The first operational carrier, HMS Argus of the Royal Navy, was commissioned in 1918, paving the way for naval aviation. During World War II, carriers replaced battleships as the dominant capital ships, playing decisive roles in battles such as Midway and Coral Sea.
Since then, carriers have evolved from converted cruisers to purpose-built nuclear-powered giants, capable of supporting dozens of aircraft and operating for months without refuelling.
Aircraft Carrier Design, Capabilities, and Strategic Role
Modern aircraft carriers are among the most complex and powerful warships ever built, combining advanced engineering with unmatched operational flexibility. Their design not only enables the projection of air power across the globe but also supports a wide range of military and humanitarian missions.
An aircraft carrierβs structure and onboard systems are meticulously engineered to sustain high-tempo operations at sea. The flat flight deck enables the launch and recovery of aircraft, while hangar decks store and maintain them. Launch systemsβwhether ski-jump ramps or advanced catapultsβallow jets to take off within short distances. Powerful propulsion systems, including nuclear power in the case of U.S. Nimitz and Ford-class carriers, give these vessels virtually unlimited range. Defences include escort ships, anti-aircraft weapons, and sophisticated electronic warfare systems. Housing between 4,000 and 6,000 personnel, carriers are equipped with living quarters, medical facilities, command centres, and amenities such as shops and gyms.
Beyond their engineering marvel, aircraft carriers are strategic assets that influence global security and diplomacy. They project power by enabling rapid deployment of air forces anywhere in the world, serve as a deterrent to potential adversaries, and provide humanitarian aid during natural disasters through their medical and logistical resources. Additionally, their advanced sensors and reconnaissance aircraft extend surveillance capabilities over vast ocean and coastal regions.
Aircraft Carriers Around the World
As of 2024β25, only a handful of countries around the globe operate aircraft carriers:
- United States: Dominates with 11 super carriers, all nuclear-powered and equipped to operate large air wings.
- China: Operates 2 active carriers (Liaoning, Shandong) plus the advanced Fujian entering sea trials, placing it second in terms of fleet size.
- India: Maintains 2 carriersβINS Vikramaditya and the indigenous INS Vikrantβwith plans for a third, INS Vishal.
- United Kingdom: Operates 2 STOVL carriers, HMS Queen Elizabeth and HMS Prince of Wales.
- Italy: Has 2 light carriersβCavour and Giuseppe Garibaldi.
- Japan: Runs 2 carriersβIzumo and Kagaβconverted from helicopter carriers to operate F-35Bs.
- France: Operates 1 nuclear-powered carrier, Charles de Gaulle.
- Russia: Has 1 carrier, Admiral Kuznetsov, which is largely non-operational and facing decommissioning.
- Spain: Owns 1 light carrier, Juan Carlos I.
- Turkey: Commissioned 1 light carrier, TCG Anadolu, capable of STOVL and drone operations.
- Brazil: Operates 1 light carrier, Atlantico (formerly HMS Ocean).
- Thailand: The only Southeast Asian nation to operate a carrier, HTMS Chakri Naruebet.
- United States has 11 carriers which is approximately 40% of the global total.
- Countries with 2 carriers: China, India, Italy, Japan, UK.
- 1-carrier nations: France, Russia, Spain, Thailand, Turkey, Brazil.
Global Trends and Strategic Shifts in Aircraft Carrier Development
China is rapidly expanding its naval aviation capabilities, with the Fujian carrier already launched and additional projectsβpotentially including a nuclear-powered Type 004βon the horizon. Meanwhile, new concepts are emerging, such as Turkeyβs TCG Anadolu, which operates drones like the Bayraktar TB3 and KΔ±zΔ±lelma. Iran and China are also exploring UAV-focused platforms, signalling a gradual shift toward unmanned carrier operations.
However, questions remain about carrier vulnerability. War games and simulations have highlighted the increasing threat posed by hypersonic missiles, sparking debate over the long-term effectiveness of carriers in high-intensity conflicts. In contrast to these advances, Russiaβs sole carrier, Admiral Kuznetsov, faces possible retirement, which would leave Russia as the only permanent UN Security Council member without an operational aircraft carrier.

Conclusion
Aircraft carriers remain symbols of naval strength and geopolitical reach. An aircraft carrier is more than just a warshipβit is a symbol of national power and a mobile command centre. Carriers play a central role in global affairs, from ensuring maritime security to delivering humanitarian assistance. While some argue that carriers are vulnerable to modern missile threats, their unmatched versatility ensures they will remain relevant in global naval strategy for decades.
Although the United States maintains dominance, emerging powers like China, India, and Turkey are enhancing their maritime capabilities. Emerging trends indicate the integration of unmanned aircrafts, stealth technology, and improved missile defense systems. The rise of drone carriers and growing threats underscore an evolving future for carrier warfare. As technology advances, these giants of the sea will continue to dominate the waves, adapting to the challenges of the modern battlefield.
