French nuclear-armed Rafale fighters could operate from Belgium under new deterrence plan.

French nuclear-armed Rafale fighters could periodically operate from Belgian air bases under a new European deterrence proposal discussed by France and its partners.

France is exploring a new deterrence framework allowing nuclear-capable Rafale aircraft to deploy temporarily to allied European air bases, including Belgium's, to reinforce deterrence and complicate targeting for potential adversaries. The Rafale jets would carry ASMP-A nuclear cruise missiles under exclusive French command, while participating countries would host deployments and joint exercises without controlling nuclear weapons. Belgium has indicated it is open to examining participation through exercises or short-term deployments.

As reported by RTL on March 3, 2026, French Rafale fighter jets equipped with nuclear weapons could periodically operate from Belgian air bases, following a new proposal by French President Emmanuel Macron to expand France’s nuclear deterrence cooperation with European partners. In practical terms, the framework allows the temporary deployment of elements of the French strategic air forces to allied countries, potentially including Belgium, Germany, the Netherlands, Poland, Denmark, Sweden, Greece, and the United Kingdom, while maintaining national control over nuclear weapons. Such deployments would occur during exercises, deterrence demonstrations, or strategic signaling activities.

The objective is to reinforce the credibility of nuclear deterrence across Europe by demonstrating the ability to disperse nuclear-capable aviation across multiple air bases. For decades, most European states relied primarily on the U.S. nuclear umbrella, within NATO, for strategic deterrence against nuclear threats. However, concerns about geopolitical tensions, Russia’s full-scale invasion of Ukraine, and uncertainty surrounding long-term American security commitments have encouraged several European governments to examine complementary deterrence arrangements. France, which has been the only nuclear-armed state within the European Union since the United Kingdom left the bloc in 2020, has therefore proposed extending the strategic relevance of its deterrent to allied countries.

Macron also announced that France intends to increase the number of nuclear warheads in its arsenal from the current level of fewer than 300, although no precise future figure has been announced, marking the first increase in the French nuclear arsenal since the early 1990s. France has also indicated that it will no longer publicly disclose the exact size of its nuclear stockpile in the future. France’s nuclear deterrence system is structured around two main operational components designed to ensure a continuous retaliatory capability. The first component is the sea-based element consisting of ballistic missiles deployed aboard nuclear-powered submarines. These Triomphant-class submarines carry M51.2 submarine-launched ballistic missiles capable of ranges exceeding 8,000 km and are equipped with multiple nuclear warheads.

At least one of the four submarines is maintained on operational patrol in the Atlantic Ocean at all times, ensuring the permanence of the sea-based deterrent. The second component is the Rafale fighter jet operated by the Strategic Air Forces and naval aviation, which could carry ASMP-A air-launched nuclear cruise missiles. These aircraft can conduct long-range strike missions and provide flexibility for signaling missions and visible demonstrations of nuclear capability. This aerial component provides the operational basis for potential deployments to allied countries within a new forward deterrence framework. The Rafale B represents the main fighter jet assigned to the airborne component of France’s nuclear deterrent, as it is certified to carry the ASMP-A air-launched nuclear cruise missile, which has a range of more than 500 km and carries the TNA thermonuclear warhead, with a selectable yield estimated at up to 300 kilotons.

Powered by two Safran M88-2 turbofan engines, each producing 50 kN of dry thrust and 75 kN with afterburner, the Rafale can reach a maximum speed of Mach 1.8 and a combat radius exceeding 1,000 km in strike configuration, and even more when refueled by tanker aircraft such as the Airbus A330 MRTT. Its internal fuel capacity reaches about 4.7 tonnes and can be extended with external fuel tanks carried on its 14 external hardpoints. The aircraft is equipped with the RBE2-AA active electronically scanned array radar, the SPECTRA electronic warfare system, and an integrated optronic front sector sensor for target detection and tracking. By dispersing nuclear-capable aircraft across multiple locations, the survivability of the French deterrent force can be increased, and potential adversaries face more complex targeting calculations.

Those Rafales could deploy to partner air bases for limited periods to conduct exercises, training missions, or deterrence demonstrations. Such deployments may also involve joint exercises with allied conventional forces participating in deterrence-related activities. France has also opened the possibility for allied personnel to participate in visits to nuclear strategic installations to reinforce the credibility of its proposal, while maintaining the nuclear weapons themselves under French control. Belgium has been identified as one of the countries that could play an operational role in this framework, and political reactions within the country have indicated cautious openness to examining the proposal.

Belgian Foreign Affairs Minister Maxime Prévot indicated that extending the French nuclear umbrella to European partners appears to be a constructive initiative while emphasizing that the objective remains deterrence rather than the preparation of war. In practical terms, participation could involve French aircraft equipped with nuclear weapons operating from Belgian air bases such as Kleine-Brogel or Florennes during exercises or temporary deployments as part of a shared protection arrangement. The minister also stressed that Belgium is not preparing to enter a conflict and that cooperation would primarily reflect solidarity among European allies. Belgian Prime Minister Bart De Wever confirmed that Belgium is prepared to cooperate closely with France on strengthening deterrence and European defense policy.

The federal government approved the principle of an ad hoc cooperation framework, which does not require immediate major financial investments. Belgian authorities also indicated that participation could provide additional operational expertise and reinforce the country’s existing participation in NATO nuclear sharing arrangements. Within NATO, several European states host U.S. nuclear bombs on their territory, while some fighter jets maintain the capability to deliver them if required by alliance decisions. Belgium is widely believed to host at least a dozen American B61 nuclear bombs stored at military facilities in Kleine-Brogel. The possible deployment of French Rafale aircraft carrying ASMP-A nuclear cruise missiles would therefore create a comparable operational arrangement involving another nuclear-armed ally.

However, the French initiative differs from NATO nuclear sharing because it does not involve shared nuclear decision-making. In the proposal, nuclear weapons would remain under exclusive French authority and would not be transferred to partner countries. Allied territory would serve as a location for temporary deployment rather than storage or operational control of nuclear weapons, maintaining the sovereign nature of France’s deterrence doctrine. Countries involved would gain deeper integration into European deterrence planning and increased exposure to operational procedures associated with nuclear signaling missions. Joint exercises could involve allied conventional forces operating alongside French strategic aviation units, providing access to operational knowledge developed by the French strategic forces without requiring the development of independent nuclear capabilities.

The collaboration framework discussed between France and its partners has been described as an ad hoc arrangement that does not require immediate investment in new nuclear infrastructure. Instead, it relies on temporary deployments, exercises, and coordination activities, complicating targeting calculations for potential adversaries. For smaller European states, such cooperation can strengthen national defense credibility by linking their territory to a broader nuclear deterrence posture. President Emmanuel Macron has emphasized that the decision to employ French nuclear weapons will remain solely in the hands of the French head of state. Even if French nuclear-capable Rafale Bs are deployed temporarily to allied territory, partner countries will not participate in nuclear decision-making.

This principle reflects the longstanding doctrine of the French deterrent, which has always been maintained under strict national command. France historically developed its nuclear forces to ensure full sovereignty over strategic decision-making independent from NATO’s nuclear planning structures. The forward deployment framework, therefore, would mirror the existing US doctrine, which allows multinational operational cooperation while preserving national control over nuclear weapons. Belgian participation would remain limited to exercises, operational coordination, and hosting deployments, as the command authority over nuclear weapons remains entirely French...or American.
