Far from shore and out of sight, this floating city of steel can launch jets, guide drones, and host thousands of sailors at once, all while patrolling international waters at highway speeds.
The aircraft carrier, explained in plain terms
An aircraft carrier is first and foremost a warship designed to act as a mobile airbase.
Its wide, flat deck serves as a runway at sea, allowing fighter jets, surveillance planes and helicopters to take off and land without needing an airfield on land.
This idea dates back to the early 20th century. In 1910, an American pilot carried out the first experimental take-off from a ship, using the cruiser USS Birmingham as a platform. The test looked almost improvised, but it opened the door to a completely new way of fighting at sea.
Over time, these improvised decks turned into fully fledged floating airfields, with catapults, arresting wires and huge hangars hidden below the surface of the deck.
Instead of bringing aircraft back to base, the base itself sails to where the planes are needed.
Strategically, this changes everything. A carrier can be moved near a crisis zone without crossing someone else’s borders. It can launch aircraft to protect sea lanes, monitor rival fleets, or provide air cover for troops on land.
A floating city with its own postcode
An aircraft carrier is not just a warship. It functions much like a small town or a remote industrial site.
On board, there are sleeping quarters, a hospital, kitchens, workshops, a post office, even gyms and chapels. Thousands of people live and work there for months at a time.

Each group has a specific job: pilots and aircrew, mechanics, radar operators, nuclear engineers, firefighters, doctors, cooks. The ship never really sleeps; somewhere on board, at every hour of the day and night, someone is maintaining an engine, watching a radar screen or preparing for the next flight.
The giant in question: USS Gerald R. Ford
The current record-holder for size is American. Since 2017, the USS Gerald R. Ford (CVN-78) has been the largest aircraft carrier, and the largest active military ship, on the planet.
Built by Northrop Grumman, it is the lead vessel of a new generation of US carriers and a direct successor to the long-serving Nimitz class. Its construction took more than a decade and cost around $13 billion, excluding the air wing and long-term support.
At around 337 metres long, 78 metres across and roughly 100,000 tonnes, the Gerald R. Ford is slightly taller than the Eiffel Tower laid on its side.
The carrier can host close to 4,500 people when fully embarked, including the ship’s crew and the air wing that operates its aircraft. For comparison, that is roughly the population of a small town, all packed into one hull.
Speed, power and endurance
The ship is nuclear-powered, using two reactors that give it virtually unlimited range at sea. Its top speed is estimated at around 30 knots, roughly 55 km/h, fast enough to outrun many other large vessels.
Nuclear propulsion means it does not need to refuel for years, although it still relies on regular deliveries of food, spare parts and aviation fuel. This long endurance allows it to stay on station in distant waters for extended periods.
- Length: approx. 337 m
- Beam (width): approx. 78 m
- Displacement: about 100,000 tonnes
- Maximum speed: around 30 knots (≈ 55 km/h)
- Personnel on board: up to 4,500 people
- Aircraft capacity: around 90 aerial vehicles
How many aircraft can it actually carry?
This is where the ship truly earns its status as a heavyweight in naval strategy.
The USS Gerald R. Ford has been designed to host close to 90 aircraft in total, combining different types of machines and roles. Those typically include:
- Carrier-based fighter jets for air combat and ground attack
- Airborne early-warning aircraft with large radar systems
- Helicopters for anti-submarine warfare and search-and-rescue
- Logistics aircraft for transport and replenishment tasks
- Drones for surveillance and, increasingly, strike missions
The ship’s flight deck functions like a mini airport that never closes: take-offs, landings and maintenance run on a tight schedule, day and night.
By comparison, France’s flagship, the nuclear-powered carrier Charles de Gaulle, usually carries about 40 aircraft and a crew of roughly 1,900 people, including its air wing. The French ship is much smaller and lighter, reflecting a different defence budget and a different set of missions.
Technology upgrades: more aircraft, less crew workload
The sheer size of the Gerald R. Ford is only part of the story. Much of the investment has gone into systems that should let it run more efficiently than older US carriers.
The ship features electromagnetic aircraft launch systems, replacing the traditional steam catapults. These EMALS devices accelerate aircraft using powerful linear motors.
Compared with steam systems, they are designed to be smoother and more flexible, putting less stress on the airframes and allowing a higher tempo of operations.
The arresting gear that stops landing jets has also been modernised. On top of that, the island — the tower structure on the deck — has been reshaped and pushed slightly aft, freeing more space on the flight deck for moving and parking aircraft.
The stated goal is simple: more sorties per day, less strain on the crew and machinery.
Every extra mission launched from the deck translates into more surveillance, more deterrence and more options for commanders operating far from home ports.
Why size still matters at sea
In an age of satellites, cyber attacks and long-range missiles, huge warships might look old-fashioned at first glance. Yet aircraft carriers still sit at the centre of many naval strategies.
A single carrier strike group, built around a ship like the Gerald R. Ford, includes destroyers, frigates, a submarine and support ships. Together, this formation brings air defence, anti-submarine warfare, missile capabilities and logistics support.
When such a group moves near a contested area, regional powers take note. It signals political intent as much as military strength. The presence alone can reassure allies and complicate the calculations of potential adversaries.
Risks, vulnerability and changing threats
Size also brings risk. A large carrier is a highly visible, high-value target. Modern anti-ship missiles, torpedoes and drones are being designed specifically to threaten these ships.
This drives constant efforts to update defences: layered missile shields, electronic warfare systems, decoys and submarine escorts. The carrier itself rarely sails without a ring of protection from other ships and aircraft.
Naval planners now test scenarios in which carriers must operate farther from hostile shores, relying on longer-range jets and missiles. Simulations model swarms of drones attacking from multiple directions or stealthy submarines tracking the group in deep water.
Whether those threats can truly sideline the carrier concept is still debated, but no major navy has yet chosen to abandon it.
Key terms that help make sense of the numbers
Several commonly used terms can be confusing at first glance. A few are worth clarifying:
- Displacement: the weight of water a ship pushes aside when afloat, effectively equal to the ship’s weight. For the Gerald R. Ford, this is about 100,000 tonnes.
- Knot: a nautical speed unit. One knot is about 1.85 km/h. So 30 knots is close to 55 km/h.
- Sortie: a single mission flown by one aircraft. Carrier commanders track how many sorties they can generate per day as a measure of combat power.
- Strike group: the full group of ships and submarines that typically escort and support a carrier.
What this scale means in real situations
Consider a natural disaster striking a coastal nation with damaged airports and blocked roads. A carrier of this size can be redirected offshore, bringing helicopters, medical teams, drinking water units and generators. Aircraft originally meant for combat can instead ferry supplies and evacuate the injured.
In a different scenario, a regional crisis begins to escalate. Instead of building new bases or negotiating emergency landing rights, a state can send a carrier strike group near the area. Within hours of arrival, its aircraft can patrol, gather intelligence and, if needed, carry out precise strikes.
These concrete examples show why countries continue to spend vast sums on such ships. With unmatched reach, a carrier like the USS Gerald R. Ford can project power, provide relief, or simply maintain a visible presence, all from the same gigantic, 337‑metre platform ruling the oceans.
