Italy is preparing to host Steadfast Noon, NATO’s annual nuclear deterrence exercise, beginning on October 13, 2026. The operation will involve 17 allied countries and is expected to run for around ten days. Its name may sound alarming, especially at a time when Europe is dealing with Russia’s war against Ukraine, renewed nuclear rhetoric and a wider debate about military spending. Yet one distinction needs to be made immediately: Steadfast Noon is a nuclear deterrence exercise, but it does not involve the use of live nuclear weapons.
That does not make the exercise meaningless or purely symbolic. It is designed to test the procedures, coordination and readiness that underpin NATO’s nuclear deterrence posture. Understanding what is confirmed, what remains undisclosed and what is politically disputed is essential to covering the story accurately.

What is Steadfast Noon, and when does it begin?

NATO has announced that the 2026 edition will begin on Tuesday, October 13, with Italy serving as the host country. The Alliance says 17 nations will participate and that the overall scale will be comparable to previous editions. The Italian Air Force has also stated that the exercise was planned well in advance and is part of NATO’s regular training schedule.
Steadfast Noon is held every year, with participating Allies and host arrangements changing over time. Its purpose is to maintain readiness and test procedures connected to the Alliance’s nuclear deterrence mission. NATO Secretary General Mark Rutte has described the exercise as a way to ensure that the Alliance’s capabilities remain safe, secure, effective and credible.
NATO says the exercise is not directed against any country and is not linked to a particular international crisis. That official position is important, even though the exercise is taking place against a tense geopolitical background. The fact that an event coincides with a period of international instability does not, by itself, prove that it was organized in response to a specific threat.

Why is it called a nuclear exercise if no nuclear weapons are used?

The distinction between a nuclear exercise and the actual use of nuclear weapons is central to the story. Steadfast Noon does not involve detonations or the use of live nuclear warheads. Instead, it trains personnel and tests procedures related to NATO’s nuclear deterrence mission.
A complex military operation requires much more than an aircraft assigned to a particular role. It depends on communication, planning, command and control, refuelling, surveillance, escort and coordination among different units. Some participating aircraft may be associated with nuclear-capable missions, while others provide conventional support. The exercise tests how those different elements work together.
NATO does not publish every detail of the scenarios or operational procedures. It would therefore be inaccurate to claim that a particular strike sequence, target or flight profile will be used unless that information has been officially confirmed. The public description is narrower: Steadfast Noon is intended to test readiness and cooperation among the participating Allies, without using live weapons.
The exercise nevertheless concerns a real part of NATO’s military posture. Nuclear deterrence is one element of the Alliance’s broader approach to defence, alongside conventional forces, missile defence and other capabilities. The fact that no live nuclear weapons are used during the exercise does not mean that the subject itself is unrelated to nuclear strategy.

Which Italian bases and airspace areas are involved?

Reports published in the days before the exercise have identified several Italian military air bases and areas of activity. The locations cited include Aviano in Friuli-Venezia Giulia, Ghedi in Lombardy, Amendola in Apulia, Gioia del Colle and Trapani. Air activity is also expected to involve routes and training areas over the Tyrrhenian Sea and across parts of the Italian peninsula.
Technical aviation documents and reporting based on them have highlighted particular periods of military activity on October 13, 14, 16 and 20. These notices are useful for understanding how military activity may affect designated airspace, but they should not be mistaken for a complete public schedule of every mission.
There is also an important limitation: the appearance of a base in an aviation notice does not automatically mean that every aircraft participating in Steadfast Noon will take off from that location or that each base will perform the same task. Technical notices describe airspace restrictions, corridors and time windows. They do not necessarily reveal the full operational plan.
The available information points to a geographically broad exercise rather than an activity confined to a single airfield. However, exact mission assignments, aircraft numbers by location and the full list of operational details should not be presented as established facts unless official sources disclose them.

Aviano, Ghedi and the wider nuclear-sharing debate

The Italian exercise has renewed attention on a larger issue: Italy’s role in NATO’s nuclear arrangements. Open-source specialist research identifies Aviano and Ghedi as the two Italian bases associated with the presence of US nuclear weapons under NATO’s nuclear-sharing framework.
The exact number and distribution of weapons are not fully confirmed in a comprehensive public official inventory. Estimates published by different sources vary, so a specific number should not be presented as an established fact without clear and authoritative confirmation.
Nuclear sharing is a framework through which some non-nuclear NATO members take part in consultations and arrangements related to the Alliance’s nuclear deterrence posture. The United States retains custody of its nuclear weapons in peacetime. Any decision involving their possible use in a crisis would be a political and military matter governed by NATO’s procedures, rather than an automatic consequence of an exercise.
This distinction matters because the presence of nuclear weapons at a base, the participation of aircraft in a training activity and the actual use of a nuclear weapon are three different things. They are connected to the same strategic framework, but they are not interchangeable.
Steadfast Noon does not mean that nuclear bombs will be detonated or that the exercise itself constitutes an operational decision to use them. It means that NATO is practising elements of the deterrence mission that it maintains as part of its defence posture.

What is actually being practised?

NATO has not released the full operational scenario for the 2026 exercise. The safest description is therefore the one supported by the Alliance’s public statements: participating forces will test procedures, readiness, coordination and the ability to operate together.
Previous editions have included different types of aircraft and support assets, including fighter aircraft, aerial refuelling platforms, surveillance aircraft and command-and-control capabilities. Those examples help explain the general structure of this kind of exercise, but they should not automatically be treated as a confirmed list of every aircraft or capability involved in the Italian edition.
The reason these supporting roles matter is straightforward. An operation involving several countries cannot rely on individual aircraft acting in isolation. Units need to exchange information, follow compatible procedures and coordinate timing and support. Training helps identify weaknesses before a real crisis occurs.
The exercise also tests the organisational side of military readiness. Planning, communication and command arrangements can be as important as the performance of the aircraft themselves. In a multinational alliance, interoperability is a practical requirement: forces from different countries need to be able to work together under agreed procedures.

Why NATO conducts the exercise every year

NATO’s official argument is based on deterrence. The Alliance maintains that a credible defensive posture helps discourage potential adversaries from launching an attack. Its nuclear forces are described as one component of a broader mix of capabilities intended to protect allied territory and prevent coercion.
For NATO, exercises such as Steadfast Noon help demonstrate that the Alliance can maintain the readiness, safety and security standards required for its nuclear mission. The annual format also allows participating countries to rehearse procedures and preserve cooperation over time.
Critics question whether nuclear deterrence reduces the risk of war or perpetuates a system that leaves Europe exposed to catastrophic escalation. Supporters argue that the possibility of a credible response is precisely what makes an attack less likely. These are competing strategic judgments, not simply disagreements about the technical details of an air exercise.
The distinction between the Alliance’s stated rationale and its critics’ interpretation should remain clear. NATO says Steadfast Noon is a routine exercise, planned in advance and not aimed at a specific country. Opponents may argue that the exercise reinforces a dangerous nuclear posture, but that is a political assessment that should be attributed to those making it.

The international backdrop: Russia, Ukraine and nuclear rhetoric

The announcement comes during a period of heightened concern about European security. Russia’s war against Ukraine, repeated disputes between Moscow and NATO members and renewed public discussion of nuclear weapons have made deterrence a central issue in European politics.
That context explains why Steadfast Noon has attracted attention beyond military circles. An exercise involving nuclear-capable forces is inevitably scrutinised more closely when public debate is already focused on escalation, arms control and the possibility of a wider confrontation.
However, it is important not to confuse the broader geopolitical context with the immediate reason for the exercise. NATO says Steadfast Noon was planned well in advance and is not connected to a particular crisis or recent international development. There is no sufficient public evidence to state that the 2026 exercise was called specifically in response to a single Russian statement or a particular military incident.
A balanced account can acknowledge both facts: the exercise takes place amid heightened tensions, while the official explanation is that it belongs to NATO’s regular training calendar. Neither point cancels out the other.

The political controversy in Italy

The exercise has also triggered a domestic debate about transparency and Italy’s participation in nuclear deterrence. The issue gained attention after technical information about military activity and airspace arrangements became public. Some representatives of Alleanza Verdi e Sinistra announced plans to seek parliamentary clarification.
AVS co-spokesperson and MP Angelo Bonelli criticised the exercise and argued that Italy should focus on disarmament and diplomacy. He has advocated joining the United Nations Treaty on the Prohibition of Nuclear Weapons and withdrawing nuclear weapons from Italian territory. These are political positions opposed to Italy’s role in NATO’s nuclear-sharing arrangements; they should not be confused with a neutral description of the exercise’s military purpose.
There are two distinct questions in this controversy. One concerns strategy: should Italy participate in an alliance whose defence posture includes nuclear deterrence? The other concerns transparency: how clearly should the government inform Parliament and the public when Italy hosts an exercise connected to that mission?
The questions are related, but they are not identical. A person may support NATO membership while asking for more public information about nuclear policy, or oppose nuclear deterrence while accepting that the exercise is part of an established alliance framework. The democratic debate is better served by keeping those issues separate.
Any claims that the government violated a specific obligation or deliberately concealed information would require documentary evidence. Parliamentary questions and political criticism are part of the process, but they do not by themselves establish that a legal violation occurred.

Italy has hosted Steadfast Noon before

The 2026 edition is not the first time Italy has hosted the exercise. According to information reported by the Italian Air Force and news agencies, previous Italian-hosted editions took place in 2010, 2013, 2014, 2018, 2021 and 2023.
That history is relevant because it shows that Steadfast Noon is a recurring NATO activity, with hosting arrangements rotating among Allies. It was not created in response to the latest news cycle. At the same time, the fact that the exercise has taken place before does not settle the political debate over whether Italy should continue to host it.
The question of continuity is part of the wider argument over nuclear deterrence in Europe. For NATO, regular training supports readiness and credibility. For anti-nuclear campaigners, repetition can normalise a strategy that they believe should be replaced by disarmament and diplomatic agreements.

What is confirmed — and what remains unknown?

As of October 10, the confirmed public information is that Steadfast Noon will begin on October 13, 2026, will be hosted by Italy, will involve 17 NATO countries and will not use live nuclear weapons. The exercise is intended to test readiness, procedures and cooperation connected to the Alliance’s nuclear deterrence mission.
Reports also identify several Italian bases and airspace areas associated with the wider activity. But the complete operational scenario, all aircraft assignments and a full official inventory of any nuclear weapons stationed at Italian bases are not publicly confirmed in the information available.
It is also not established that the exercise is a direct response to a particular Russian action. NATO explicitly says it is not directed against any country and is not linked to current world events. Political commentary may interpret the exercise as a signal to Moscow, but that interpretation should be attributed rather than presented as a proven operational objective.
These distinctions matter. Calling Steadfast Noon a nuclear deterrence exercise is accurate. Saying that live nuclear weapons will be used is not. Claiming that the exercise is aimed at a specific country goes beyond the official information available.

A military exercise with political consequences

Steadfast Noon raises a larger question that extends beyond aircraft and training schedules: what role should Italy play in Europe’s nuclear deterrence system?
NATO’s position is that a credible deterrent helps prevent aggression and protects the Alliance’s members. Critics argue that reliance on nuclear weapons carries unacceptable risks and that Europe should move towards disarmament and diplomacy. Both positions form part of the political debate surrounding the exercise, although they rest on very different assumptions about how security can best be achieved.
The most useful way to understand the event is to avoid both alarmism and complacency. There is no planned use of live nuclear weapons during Steadfast Noon, but the exercise is not merely a routine flight demonstration either. It concerns procedures and capabilities associated with one of the most consequential parts of NATO’s defence strategy.
From October 13, Italy will host an exercise that is military in its immediate purpose and political in its wider significance. The central facts are clear: the exercise is planned, multinational, connected to nuclear deterrence and does not involve live nuclear weapons. What remains open to debate is whether the strategy it rehearses is the best way to preserve peace and security in Europe.
