Churning the Atlantic or cutting across the Mediterranean, a colossal grey silhouette now embodies naval power in the 21st century.
This floating stronghold is not just another warship. It is a mobile air base, a small city at sea and a symbol of strategic dominance, all concentrated into one steel giant.
The aircraft carrier, a city that sails
An aircraft carrier is essentially an airfield that moves. Instead of runways on land, it offers a long, flat deck where fighter jets, helicopters and surveillance aircraft can land and take off.
The concept dates back more than a century. In 1910, a US pilot took off experimentally from the deck of the cruiser USS Birmingham, proving that naval aviation was possible. From that fragile start, navies have created vessels that can now launch dozens of aircraft thousands of kilometres from their home shores.
For political leaders, an aircraft carrier means reach. It allows a state to project power far from its own territory, respond quickly to crises and reassure allies with a visible, highly mobile presence.
An aircraft carrier is both a military tool and a political message: “we can be here, and we can stay here”.
On board, life looks more like a town than a ship. Thousands of sailors, pilots, engineers, medics, cooks and technicians share the same steel island. There are sleeping quarters, gyms, workshops, command centres, medical facilities and even chapels. The ship operates round the clock, in tightly choreographed shifts.
The giant that tops them all: USS Gerald R. Ford
Among these sea giants, one stands above the rest: the USS Gerald R. Ford (CVN-78). Built in the United States and delivered in 2017, it is currently the largest military ship afloat and the first of a new generation of US carriers.
Named after former US president Gerald Ford, it took more than a decade to construct. The price tag reached around $13 billion, not including the air wing and decades of future operations.
At 337 metres long, 78 metres wide and around 100,000 tons, USS Gerald R. Ford is slightly longer than the Eiffel Tower is tall.

The vessel is powered by two nuclear reactors, giving it virtually unlimited range in terms of propulsion. Refuelling concerns shift from the ship itself to the aircraft and the thousands of people on board. It can reach speeds of around 30 knots, or roughly 55 km/h, which is fast for a ship of such scale.
Capacity is just as striking. The Ford can host roughly 4,500 people at peak deployment. That includes the ship’s crew, the air wing and staff from various support units. At full tempo, the carrier operates like a giant machine, with constant aircraft movements, maintenance, planning and logistics.
How many aircraft can it carry?
The raw power of an aircraft carrier lies in its air group. USS Gerald R. Ford can carry close to 90 aircraft of different types: fighter jets, early-warning planes, helicopters and, increasingly, drones.
- Fighter jets for air superiority and ground strikes
- Early-warning aircraft to monitor airspace and sea lanes
- Helicopters for anti-submarine warfare and search-and-rescue
- Drones for surveillance and, potentially, future strike missions
By comparison, France’s flagship carrier, Charles de Gaulle, typically embarks around 40 aircraft and about 1,900 personnel. That still makes it a major asset for the French Navy, yet the Ford operates on a different scale entirely.
Technology packed into a floating airfield
Beyond its sheer size, the Ford-class introduces several key technologies meant to increase efficiency and reduce crew workload over time.
Electromagnetic catapults and advanced arresting gear
Previous US carriers used steam catapults to hurl jets into the air. The Ford replaces these with electromagnetic catapults, known as EMALS. They use electric power to accelerate aircraft along the deck.
Electromagnetic catapults offer smoother acceleration, reducing stress on aircraft structures and potentially extending their service life.
On the landing side, advanced arresting gear uses sophisticated energy-absorbing systems to catch incoming aircraft more precisely than older hydraulic cables. Together, these systems aim to increase the number of launches and recoveries the carrier can conduct in a day.
Redesigned island and more efficient deck operations
The “island” — the tower rising from the deck — has been moved slightly aft and redesigned. This change is not cosmetic. The new layout helps free up more usable deck space and improves visibility for deck crews.
Ford-class carriers also aim to reduce the number of sailors needed for routine operations by relying on more automation, advanced sensors and improved logistics systems. Fewer crew members can mean lower long-term operating costs, though the initial investment is high.
How the Ford compares with other carriers
| Carrier | Country | Length | Approx. displacement | Aircraft capacity |
|---|---|---|---|---|
| USS Gerald R. Ford | United States | 337 m | ~100,000 tons | ~90 aircraft |
| Charles de Gaulle | France | 261 m | ~42,000 tons | ~40 aircraft |
| Queen Elizabeth-class | United Kingdom | 280 m | ~65,000 tons | Up to ~40 aircraft |
Different navies make different choices. The UK’s Queen Elizabeth-class carriers, for example, use a “ski-jump” ramp and short take-off jets instead of catapults. China and India are also expanding their carrier fleets, though none currently match the Ford’s scale and technology package.
What does such a ship actually do?
From the outside, an aircraft carrier may look like a symbol more than a tool, but its missions are very concrete. In peacetime, carriers take part in multinational exercises, show presence in contested areas and help during humanitarian crises.
In conflict, a carrier group can launch airstrikes, enforce no-fly zones, secure sea lanes and provide support for ground forces. Because the ship is mobile, it can reposition in international waters without relying on foreign bases.
An aircraft carrier rarely sails alone: it travels at the centre of a carrier strike group, with destroyers, frigates, submarines and support ships.
This group protects the carrier against submarines, missiles, aircraft and cyber threats. It is better seen as a moving system than a single vessel.
Key terms that shape carrier power
Several technical notions often appear in discussions about carriers and can change how they are perceived.
Displacement: This refers to the weight of water a ship pushes aside when it floats, which matches the ship’s own weight. For the Ford, that is around 100,000 tons, far more than most commercial vessels.
Nuclear propulsion: The Ford’s reactors produce heat that generates steam, which then drives turbines to turn the propellers and produce electricity. This gives the ship long endurance, but also demands highly trained crews and strict safety measures.
Sortie rate: This is the number of aircraft missions the carrier can launch in a given time. Higher sortie rates mean faster reaction to threats or crises. Much of the Ford’s design — from deck layout to catapult technology — aims at boosting this figure.
Risks, costs and future scenarios
A ship of this scale is not without downsides. It concentrates thousands of people and billions of dollars of hardware into one target. In any major conflict with advanced missiles or submarines, protecting such a vessel would be a demanding challenge.
The financial side also raises questions. The combination of construction cost, maintenance, nuclear handling and aircraft procurement weighs heavily on defence budgets. Some analysts argue that future conflicts may favour smaller, more dispersed platforms, including drones launched from smaller ships or from land.
Yet, for now, major powers continue to invest in these giants. In a crisis near a disputed coastline, the presence of an aircraft carrier can change the calculation for all players. It allows rapid air operations without the need to negotiate land bases, and it can switch theatres within days.
Looking ahead, navies are already imagining carriers packed with uncrewed aircraft, lasers for defence and even more automation on board. The USS Gerald R. Ford, with its 337 metres of steel and its 100,000 tons of displacement, marks a step in that direction: a massive, moving symbol of how states still try to rule the oceans from floating runways.
