Nuclear warships have returned to the debate in Italy after Fincantieri confirmed studies on nuclear propulsion and third and fourth generation reactors. The proposal could expand naval autonomy, reduce refueling on long missions, and bring the country closer to technologies currently restricted to a few powers.
Nuclear warships have returned to Italy’s radar after Fincantieri, one of the country’s largest shipbuilders, confirmed that it is studying the use of nuclear propulsion in military vessels. The information was addressed by CEO Pierroberto Folgiero on June 25, 2026, during a conversation with journalists in Milan.
According to the executive, there is still nothing concrete to happen in the short term, but the company has been analyzing technologies related to third and fourth generation reactors. The move comes as the Italian Armed Forces evaluate ways to develop nuclear-powered naval capabilities, a complex, expensive area currently concentrated in a few powers.
Nuclear propulsion can change naval autonomy
The main advantage of nuclear warships is autonomy. Compared to conventional vessels, nuclear propulsion allows long-range missions without the same dependence on frequent refueling, which can change the operational planning of a navy.

This feature is especially relevant for forces that need to remain at sea for long periods, protect routes, monitor crises, or operate far from their bases. Less refueling means more freedom of movement, but it also requires a much more sophisticated technical structure.
Fincantieri says it is studying new generation reactors
Pierroberto Folgiero stated that Fincantieri has been studying the technology, including third and fourth-generation reactors. The executive also indicated that the company seeks partnerships not only for the reactor itself but for the value chain and other components necessary for the system.
This point shows that the discussion goes beyond the nuclear engine. To build and operate such ships, it is necessary to integrate naval design, radiological safety, specialized maintenance, crew training, industrial chain, regulation, and support capability over decades. Nuclear propulsion is not an isolated piece of equipment but a strategic country decision.
Technology is expensive and requires highly specialized personnel
Despite the advantages, the source highlights that building, operating, and maintaining this type of technology is extremely expensive. The challenge involves not only the initial investment in the ship but the entire life cycle of the vessel, including infrastructure, safety control, maintenance, disposal, and training of specialists.
Nuclear warships also require highly trained personnel. A navy that adopts this technology needs to deal with strict standards of operation and supervision. Any failure in onboard nuclear systems can have much greater technical, environmental, political, and diplomatic consequences than common naval maintenance problems.
Few powers operate nuclear military ships in Europe
In Europe, only France, the United Kingdom, and Russia currently operate nuclear-powered warships, according to the information disclosed. This helps to gauge the complexity of the Italian ambition. Joining this group would require more than industrial will; it would require political continuity, heavy investment, and technological maturity.
For Italy, studying this possibility may represent a shift in the naval debate. Even though the project is still under evaluation, the mere opening of the topic shows interest in long-term capabilities. It is not a quick purchase, but a possible structural transformation in Italian maritime defense.
Project Minerva appears as part of the discussion
In 2023, the Italian Ministry of Defense launched Project Minerva, with the participation of Fincantieri, to assess the feasibility of integrating next-generation nuclear reactors into military vessels. The analysis includes both surface ships and submarines, focusing on electricity and propulsion.
This project helps explain why the topic has returned to the center of conversations. Italy is not just imagining nuclear warships in theory; it is investigating the application of the technology in future military platforms. Still, the CEO’s own statement reinforces that the process is under study and should not be treated as an immediate decision.
Small reactors still generate expectation and skepticism
Folgiero acknowledged that there is skepticism around the topic but argued that it is not necessary to wait for small reactors to become a reality on land before starting to think about objectives at sea. The phrase sums up a common tension in emerging technologies: advancing early can provide an advantage but also increases financial and technical risks.
Smaller and new-generation reactors appear in various international debates as a promise for energy, industry, and defense. In the naval environment, however, the requirement is even greater. The sea imposes restrictions on space, safety, continuous operation, and maintenance that make any innovation more difficult to implement.
Autonomy does not eliminate military vulnerabilities
Nuclear propulsion can increase autonomy, but it does not make a vessel invulnerable. A ship still depends on sensors, escorts, air defense, communications, crew, maintenance, and integration with a larger naval force. Nuclear energy solves part of the logistical problem but does not replace strategy.
Therefore, nuclear warships should be seen as a capability within a broader system. If Italy moves in this direction, the discussion will involve naval doctrine, alliances, operational costs, and priorities within NATO and Europe. Autonomy at sea is an advantage, but it only makes sense when connected to a clear mission.
War in Ukraine also influences the naval debate
During the same conversation, the CEO of Fincantieri addressed lessons from the war in Ukraine related to naval drones and control of unmanned systems. He highlighted special interest in how Ukraine manages satellite connection, command, and control, even without traditional telecommunications coverage.
This comment shows that the naval future does not only involve large vessels. Surface drones, underwater telecommunications, and autonomous systems also come into the equation. Fincantieri is already working with underwater technologies and has signed an agreement with the Italian company WSense to integrate wireless solutions into the DEEP underwater drone, aimed at protecting critical infrastructures.
European defense seeks to reduce costly duplications
Another point addressed by Folgiero was the importance of collaborative projects in Europe to share research, production, and military acquisition costs. He cited the European Patrol Corvette program, involving Italy, France, Spain, and Greece, as an example of cooperation to develop a new class of patrol corvettes.
This reasoning can also influence the debate on nuclear warships. Such expensive technologies hardly advance without partnerships, industrial scale, and political coordination. In the view presented by the executive, Europe needs to avoid costly duplications and interoperability issues, especially on platforms that will sail the same seas and face similar challenges.
Italy is still far from an operational decision
Despite the impact of the topic, Fincantieri’s statement does not mean that Italy is about to launch its first nuclear vessel. The CEO himself made it clear that there is nothing concrete to happen soon. The current stage is one of study, technological evaluation, and seeking partners.
This caution is important to avoid exaggerations. Advancing to nuclear warships would require governmental decisions, budget, regulatory structure, industrial capacity, training of specialists, and political acceptance. The confirmation of studies is relevant, but it is still far from representing an Italian nuclear fleet in operation.
Debate may redefine Italy’s maritime ambitions
Even without an immediate decision, the study indicates that Italy is observing a more complex naval future. In a scenario of technological competition, pressure for strategic autonomy, and increasing importance of the Mediterranean, long-range capabilities gain weight in military planning.
The central question is whether the cost justifies the operational gain. Nuclear ships can remain longer on missions and reduce logistical dependency, but they require investments that compete with other defense priorities, such as drones, conventional submarines, air defense, sensors, and cybersecurity. Every technological choice is also a budgetary choice.
The nuclear warships have returned to the Italian debate not as an immediate reality, but as a strategic possibility. Fincantieri is studying advanced reactors, the Minerva project evaluates military applications, and Europe discusses cooperation to reduce costs. The challenge will be to transform technological ambition into a safe, viable capacity that is coherent with the real needs of the Italian Navy.
Do you think countries like Italy should invest in naval nuclear propulsion to gain autonomy at sea, or do the cost and complexity make this bet too risky? Leave your opinion in the comments.
