USS Gerald R. Ford: The World’s Largest Aircraft Carrier

Far from shore and out of public sight, this steel colossus functions as a moving patch of land, with its own airfield, power station and thousands of residents who work and live aboard.

The ship that made the sea a runway

Aircraft carriers transformed naval warfare by making the ocean a platform for launching aircraft. Rather than depending on faraway land airfields, fighter aircraft, surveillance planes and helicopters can depart from the centre of a conflict area, then return to refuel or rearm only a few hundred metres away.

The idea dates back more than a century. In 1910, a US pilot flew from an improvised wooden platform installed on the cruiser USS Birmingham, becoming the first person to launch an aircraft from a ship at sea. That trial gradually developed into a revolution. Across the following decades, warships with flat flight decks became bigger, more sophisticated and increasingly essential to modern navies.

An aircraft carrier now operates much like a self-contained town. It includes accommodation, kitchens, healthcare facilities, workshops, command centres and complex logistical networks. For months at a time, thousands of sailors, technicians, aviators and specialists remain aboard, with each person performing a particular task needed to keep the wider system operating.

Modern aircraft carriers are less “just ships” and more mobile military hubs, able to shift the balance in a region in a matter of days.

The world’s largest aircraft carrier: USS Gerald R. Ford

At the heart of the article is one vessel: USS Gerald R. Ford (CVN-78), the first ship in a new US carrier class. Handed over to the US Navy in 2017 following more than a decade of construction, it is presently the world’s largest active warship.

Constructed by Northrop Grumman’s shipbuilding division alongside Huntington Ingalls, Gerald R. Ford belongs to a new generation of nuclear-powered carriers. Its name honours former US President Gerald Ford, who held office from 1974 to 1977 and had served in the Navy during the Second World War.

Dimensions more like a skyscraper than a ship

Its basic figures explain its dominance at sea. The Ford is approximately 337 metres long from bow to stern, while its flight deck reaches roughly 78 metres across at its broadest point. It is therefore a little longer than the Eiffel Tower is high. At full load, the vessel displaces around 100,000 tonnes of water.

Despite such immense mass, the ship is capable of notably high speeds. Its nuclear reactors enable it to travel at around 30 knots, or roughly 55 km/h, and to maintain that speed without energy-related refuelling for decades. Supplies of food, replacement parts and aviation fuel, however, still depend on a continuous stream of support ships.

With 337 meters in length and about 100,000 tons in displacement, the USS Gerald R. Ford stands as the largest active military vessel ever put to sea.

A floating town for 4,500 people

The number of people aboard is comparable with that of a small town. At maximum complement, nearly 4,500 personnel live and work on the ship, including sailors, aircrew, engineers, cooks, medical teams and experts in fields ranging from nuclear engineering to radar servicing.

Daily life follows a tightly controlled schedule. Aircraft operations set the pace, as launches and recoveries take place in carefully organised cycles. Beneath the flight deck, numerous workshops and storage areas maintain the supply of spare parts. The galleys prepare thousands of meals each day. With its own water-making capability, waste handling and advanced medical provision, the ship can remain highly self-sufficient throughout lengthy deployments.

Up to 90 aircraft on one deck

A carrier’s true strength is measured by its air wing. Depending on its assigned mission, USS Gerald R. Ford can carry nearly 90 aircraft of different kinds. This combination generally features:

• Carrier-based fighters for air-defence and strike operations
• Airborne early-warning aircraft equipped with radar domes
• Helicopters used for anti-submarine warfare and rescue missions
• Transport and support aircraft for logistical duties
• Drones assigned to surveillance and reconnaissance tasks

This air group lets the ship undertake several activities simultaneously, including air patrols, precision attacks, maritime monitoring and assistance for forces on land. The carrier serves as both a command hub and a refuelling point at sea, offering commanders flexibility that land bases cannot always match.

How USS Gerald R. Ford compares with other major carriers

The scale becomes clearer when Gerald R. Ford is compared with other prominent carriers, including France’s Charles de Gaulle:

Carrier	Country	Approx. length	Displacement	Personnel	Aircraft capacity
USS Gerald R. Ford (CVN-78)	United States	~337 m	~100,000 tons	Up to ~4,500	Close to 90
Charles de Gaulle	France	~261 m	~42,000 tons	~1,900	About 40

France’s carrier normally operates Rafale Marine fighters, E‑2C Hawkeye early-warning aircraft and several helicopter types. These figures illustrate that the US flagship occupies a distinct category in both personnel numbers and air capability.

The USS Gerald R. Ford can almost double the aircraft capacity of France’s Charles de Gaulle, while carrying more than twice as many people.

Why a 13‑billion‑dollar carrier was built

Gerald R. Ford was not inexpensive to produce. Building the ship alone is commonly estimated to have cost around 13 billion dollars, excluding the development of its aircraft and supporting equipment. In return for that expenditure, the US Navy expects more than a larger vessel: it expects one that is more capable and efficient.

Its launch and recovery equipment is among its most significant features. The Ford class uses electromagnetic launch systems instead of conventional steam catapults. By using electromagnetic force to propel aircraft along the deck, these systems allow acceleration to be controlled more precisely while placing less strain on aircraft and crews.

For landings, advanced arresting gear is intended to recover aircraft with increased control and adaptability. Combined, these systems are designed to enable a faster operating tempo, with more sorties each day, reduced downtime and lower maintenance demands.

Automation is another central part of the ship’s design. More up-to-date equipment and integrated systems now carry out many repetitive activities, a change expected to reduce the number of sailors needed for certain roles and lower some operating costs during the carrier’s service life.

Strategic influence on the world stage

A vessel of this size is not simply deployed as a display of naval power. For the United States, a carrier strike group built around Gerald R. Ford communicates a political message as well as a military one. When a regional crisis emerges, sending a carrier nearby can alter the calculations of allies and possible opponents overnight.

Such a group usually consists of the carrier alongside destroyers, cruisers, a submarine and supply vessels. Together, they form a mobile protective zone combining air defence, anti-submarine protection and long-range strike power. Governments closely monitor these deployments, since the arrival of such a group may reassure partners or heighten tensions according to the circumstances.

Where a carrier goes, a piece of national strategy follows. Its position on the map often speaks louder than diplomatic statements.

Environmental and security concerns around the giant

A vessel carrying two nuclear reactors and thousands of people brings challenges beyond engineering. Environmental organisations closely scrutinise nuclear-powered ships, particularly when they berth near densely populated coastlines. Although the reactors incorporate multiple safety measures, questions about long-term waste disposal and potential accident scenarios remain sensitive.

In operational terms, the sheer scale of Gerald R. Ford is both an advantage and a weakness. Its defensive systems are sophisticated, but it remains a high-value target in any war. Modern anti-ship missiles, submarines and cyber operations all represent threats that navies must continually prepare for. Training, simulations and exercises are intended to address these possibilities, although the room for error at sea may be limited.

What the future of aircraft carriers may look like

The Ford class offers indications of aircraft carriers’ next stage of development. Designers foresee a greater number of drones on the flight deck, in both fixed-wing and rotary forms. Uncrewed aircraft can remain aloft for longer, accept greater risks and return data in real time. As the technology develops, the make-up of a carrier air wing could alter substantially.

Energy arrangements could evolve too. Nuclear power currently provides long endurance, yet research into alternative propulsion and more efficient onboard systems could reduce both logistical requirements and the environmental impact of these ships. Several navies are also experimenting with new hull designs and lower-observable shapes intended to make large surface vessels more difficult to detect.

For the moment, USS Gerald R. Ford remains a benchmark. Those interested in naval power, geopolitical strategy or major engineering projects can view it as an example of how one piece of equipment can affect global politics. Every measure, from the length of its runway to the number of bunks in its cabins, represents a decision about how a nation intends to operate far from its own coastline.

The phrase commonly used for this capability is “power projection”. Although the term can appear abstract, its effects are highly tangible. It influences where trade routes are considered secure, how smaller nations assess security guarantees and how negotiations during crises develop. When a 337‑metre carrier enters a theatre, these calculations change, sometimes before a single aircraft has left the deck.
