Nuclear aircraft carrier of the Ford class combines expanded electrical generation, A1B reactors, electromagnetic systems, and internal infrastructure comparable to a mobile base at sea.
The nuclear aircraft carrier USS Gerald R. Ford, the first ship of the Ford class of the United States Navy, combines on a single platform propulsion systems, electrical generation, embarked aviation, defense, communication, medical care, and crew support.
The vessel is powered by two A1B reactors, but the exact power available for electricity is not publicly disclosed in exact numbers by the American Navy; official sources state that the ship generates about three times more electricity than previous aircraft carriers, while open estimates associate the “600 megawatts” with thermal capacity or calculations not officially confirmed.
The comparison with a city is used to gauge the ship’s energy scale, but it needs to be treated with caution.

Putin and Kim Jong-un deepen military alliance that has already sent 14,000 North Korean soldiers to the war in Ukraine, and now the Russian Defense Minister travels to Pyongyang to finalize a new cooperation pact with stable bases until 2031.
The consumption of an urban area varies according to population, climate, industrial activity, residential pattern, and electrical infrastructure.
For this reason, the claim that the reactors could power an entire city works as an analogy of magnitude, rather than a direct equivalence between a naval system and a terrestrial electrical grid.
Nuclear energy sustains the aircraft carrier’s operation at sea
The Gerald R. Ford class was designed to function as a mobile air base.
The energy produced on board is not only used to move the ship.
It powers radars, command centers, defense systems, communications, lighting, air conditioning, potable water production, ammunition elevators, medical areas, and equipment used by the crew.
This design reduces the dependence on conventional fuels for propulsion and extends the period the vessel can remain on mission.
The nuclear autonomy, however, does not eliminate all logistical requirements.
Food, parts, ammunition, maintenance equipment, and everyday items still depend on resupply during prolonged operations.
The difference lies in the type of fuel used to move the ship.
Instead of consuming large volumes of fuel oil for propulsion, the aircraft carrier uses nuclear energy to power its displacement and generation systems.
According to the World Nuclear Association, the Ford class uses two A1B reactors more powerful than the A4W used in the Nimitz class and was designed for a prolonged service life.
Gerald R. Ford class expands on-board electrical generation
The United States Navy reports that the USS Gerald R. Ford replaced part of the steam-powered systems with electrical components.
The change alters the way energy is distributed internally and allows for the incorporation of additional systems throughout the vessel’s service life.
A RAND Corporation report on the modernization of the US aircraft carrier fleet already pointed out that the CVN 21 program, which gave rise to the Ford class, would have a propulsion plant with about 2.5 times the electrical generation capacity of the Nimitz class.
The same analysis indicated that this energy reserve would allow for the replacement of steam and hydraulic systems with electrical solutions, as well as supporting new aircraft launch and recovery technologies.
In practice, this configuration helps explain the role of on-board energy in recent aircraft carriers.
A ship of this type needs to continuously power sensors, digital networks, and aviation systems.
With greater electrical margin, the vessel gains more capacity to receive updates without relying on extensive structural changes in its architecture.
EMALS catapults replace steam systems
Among the systems associated with this change is EMALS, the English acronym for Electromagnetic Aircraft Launch System.
Unlike traditional catapults, which use steam, EMALS uses linear induction motors and electronic control to accelerate aircraft on the flight deck.
General Atomics, responsible for the system, claims that EMALS offers more controlled acceleration, expands the range of weights and speeds of launched aircraft, and reduces maintenance demands.
The equipment was also developed to accommodate both combat aircraft and lighter platforms, including support aircraft and potential embarked drones.
This aspect has a direct impact on the ship’s operational routine.
Each launch requires precision, safety, and repetition at short intervals.
According to the manufacturer, electronic acceleration control helps adjust the launch according to the type of aircraft and can reduce stress on the aircraft’s structure.
Internal infrastructure serves crew and combat systems
The expression “floating city” is often used because an aircraft carrier brings together thousands of people, work areas, accommodations, kitchens, workshops, hospitals, water systems, power generation, and command.
On the USS Gerald R. Ford, this infrastructure exists to support the primary military mission: operating an embarked air wing at great distances from the coast.
In addition to aviation, the ship needs to maintain working and survival conditions in different environments.
Available energy powers climate control, data processing, sensors, radars, and satellite communications.
At the same time, desalination systems transform seawater into usable water for the crew, while embarked medical facilities handle emergencies and routine procedures.
The scale of the infrastructure does not mean absolute independence.
An aircraft carrier operates with escorts, support ships, supply chains, and logistical planning.
The operational capability of a carrier strike group depends on the combination of nuclear autonomy, embarked aviation, layered defense, and coordinated external support.
Electrical margin prepares military ship for new technologies
The Ford class was developed with room for modernization, according to information released by the U.S. Navy.
Greater electrical generation facilitates the adoption of additional systems during the ship’s lifespan, especially in areas that demand more energy, such as sensors, digital processing, and combat technologies.
This margin is operationally relevant because aircraft carriers remain in service for decades.
Over this period, threats change, aircraft evolve, and new systems may require more power.
The design aims to allow gradual adaptations without requiring complete changes to the ship’s electrical architecture with each technological advance.
There is, however, no secure public confirmation that the USS Gerald R. Ford delivers exactly 600 megawatts of usable electricity.
The data available from official sources indicates that its electrical capacity surpasses that of previous U.S. aircraft carriers and supports systems like EMALS, in addition to reserving power for future technologies.
