The Force de dissuasion (; ), known as the Force de frappe (; 'Strike Force') before 1961, is the French nuclear deterrence force. Formulated immediately after the Second World War, it comprised a triad of air-, sea- and land-based nuclear weapons intended for deterrence; since the end of the Cold War, it is only an air- and sea-based arsenal. The French Nuclear Force, part of the French military, is the fourth largest in the world, after the nuclear triads of the United States, Russia, and China.

France's military nuclear programme was shaped not only by the Cold War, but by the trauma that resulted from the Battle of France: General Pierre Marie Gallois, one of the architects of the deterrence force, is said to have been marked "by the tragic effects of an excess of German power" in his strategic thinking. In addition to retaining a strategic advantage over Germany, France developed the Force de dissuasion to restore its status as a great power, maintain an independent security posture, and command greater influence within the NATO alliance.

As early as 1945, General Charles de Gaulle envisioned France as a nuclear power; Prime Minister Pierre Mendès France laid the groundwork for this effort in 1954. De Gaulle's presidency (1959–1969) saw France conduct its first atomic bomb test in Algeria in 1960, In 2026, President Emmanuel Macron announced that France would increase its arsenal and deterrence capabilities.

In addition to its nuclear military programme, France has a large civil nuclear programme and ranks as one of the world's largest generators of nuclear power.

History

The decision to arm France with nuclear weapons was made in 1954 by the administration of Prime Minister Pierre Mendès France under the Fourth Republic. President Charles de Gaulle, upon his return to power in 1958, solidified the initial vision into the well-defined concept of a fully independent Force de frappe that would be capable of protecting France from a Soviet or other foreign attack and independent of the North Atlantic Treaty Organization (NATO), which de Gaulle considered to be too dominated by the United States. In particular, France was concerned that in the event of a Soviet invasion of Western Europe, the U.S., already bogged down in the Korean War and afraid of Soviet retaliation against the United States, would not come to the aid of its allies in Western Europe. De Gaulle felt that France should never entrust its defense and therefore its very existence to a foreign and thus unreliable protector.

General Pierre Marie Gallois said, "Making the most pessimistic assumptions, the French nuclear bombers could destroy ten Russian cities; and France is not a prize worthy of ten Russian cities".

In his book La paix nucléaire (1975), French Navy Admiral Marc de Joybert explained deterrence:

While not referred to as such, the French nuclear posture of the time bears some significant similarities to other common policies of the era such as mutually assured destruction and massive retaliation. It remains unknown whether the French government ever seriously considered its policy different from other NATO member strategies or if their public statements were more aimed to improve morale and confidence in the French population.

In 1961 Charles de Gaulle reminded John F. Kennedy that "Germany is legally prevented from having any [nuclear weapons]," adding that "the disadvantages deriving from German possession of atomic weapons would be far greater than the advantages."

It may seem that on the surface, an avowed policy of attacking civilians was a significant departure from the typical nuclear policies of the time, but it was common for states to refer to their nuclear abilities in terms of numbers of cities destroyed. Moreover, hydrogen bombs are so powerful that if used to their full potential high civilian casualties and related collateral damage would be inevitable, thus making it unclear as to whether targeting military forces would produce a meaningfully different result compared to targeting population centers. Perhaps the most significant difference in French strategy is that it includes the option of a first strike attack, even in response to non-nuclear provocation.

France carried out its first test of an atomic bomb in Algeria in 1960 and some operational French nuclear weapons became available in 1964. Then, France executed its first test of the much more powerful hydrogen bomb over its South Pacific Ocean test range in 1968.

De Gaulle's vision of the Force de frappe featured the same triad of air-based, land-based and sea-based weapons which were deployed by both the United States and the Soviet Union. Work on the components had started in the late 1950s and was accelerated as soon as de Gaulle assumed the presidency.

Air

Initially, the Force de frappe had an airbase component of the Strategic Air Forces Command (Commandement des Forces Aériennes Stratégiques, CFAS) of the French Air Force, established in 1955 and operating 40 Sud Aviation Vautour IIB bombers. That was the end of the French mobile land-based nuclear missiles.

The French fixed S3 IRBMs at the Plateau d'Albion were considered to be approaching obsolescence and also deemed to be no longer necessary following the fall of the Soviet Union and so also were disposed of. The silos have been imploded and the missile base closed in 1999, eliminating the landbased missile leg of the French nuclear triad.

Sea

The ocean-based, mobile component of the French nuclear triad entered service in December 1971, with the commissioning of its first ballistic missile submarine, the nuclear submarine Le Redoutable, which initially carried 16 M1 intermediate-range ballistic missiles, similar to the US Polaris missiles.

Since then, the ocean-based French nuclear weapons arsenal has been expanded to a squadron of four submarines, one of which is always on patrol. Since 1985, some of the French ballistic missile subs have become obsolete. The subs have been retired and replaced by newer subs that also have 16 missile tubes apiece and carry the more advanced French M45 missile. A new submarine, the Le Terrible, was put into service on 20 September 2010, armed with the M51 missile, which is similar to the US Trident II.

In late 2025 it was reported that the M51.3 variant of the missile had entered operational service. The missile is said to have an operational range of 8,000 to 10,000 km, with a speed of Mach 25 also offering improved accuracy and penetration capabilities.

The Aéronavale or French Naval Aviation has operated a fleet of nuclear-armed aircraft since 1962, with the Dassault Etendard IV on its Clemenceau-class aircraft carriers. The Etendard could be armed with AN-52 nuclear gravity bombs. In 1978, the Dassault Super Etendard entered service, giving the Aéronavale a stand-off nuclear strike ability via its Air-Sol Moyenne Portée (ASMP) nuclear missiles. As the Clemenceau class retired from 1997 to 2000, the Super Etendard remained in service on the succeeding R91 Charles-de-Gaulle. Since 2010 it carries Rafale F3 fighters armed with the upgraded ASMP-A nuclear missiles.

Components

Land-based component

France no longer possesses land-based nuclear missiles. The IRBM base aérienne 200 Apt-Saint-Christol at the Plateau d'Albion (Vaucluse) was deactivated in 1996 and its missiles scrapped. All French Army units equipped with short-range missiles such as the Pluton and the Hadès were disbanded, their missiles scrapped and their fissile nuclear materials recycled.

Sea-based component

The French Navy includes a nuclear strategic branch, the Force Océanique Stratégique, which has contained as many as six nuclear-powered ballistic missile submarines (SSBNs) in service at one time. An estimate 80 percent of France's nuclear arsenal is sea-based.

As of 2026, ten SSBNs have been built for the French Navy:

  • Six Redoutable-class submarines, armed with 16 M4 IRBMs entered service between 1971 and 1985. The last of these, L'Inflexible (S 615), was retired in 2008.
  • Four Triomphant-class SSBNs: Le Triomphant (S 616), Le Téméraire (S 617), Le Vigilant (S 618), Le Terrible (S 619). Commissioned between 1997 and 2010, each armed with 16 M51.3 SLBMs.

Air-based component

thumb|right|[[Mirage 2000N]]The French Air and Space Force has 54 ASMP-A medium-range air-to-ground missiles with the TNA (Airborne nuclear warhead) at its disposal. These are deployed on the Dassault Rafale B, which fully replaced the Dassault Mirage 2000N in 2018.

Additionally, French Naval Aviation can operate the ASMP-A missile from the Dassault Rafale M (CATOBAR carrier variant). These aircraft are based at Landivisiau Naval Air Base and on the aircraft carrier Charles de Gaulle, allowing for operational flexibility. The Rafale M is also certified to operate from United States Navy aircraft carriers.

The locations of the nuclear missiles are secret (although many storage facilities are already known to the public, the number of warheads inside is classified and changes frequently). The range of strike aircraft is extended currently by the KC-135 and in the future by the forthcoming Airbus A330 MRTT aerial refueling fleet.

Operations

Nuclear strike order

The President of France is the sole person who can order a French nuclear strike; there is no formal requirement for the president to consult anyone before taking the decision. This authority can be transferred (devolved) along the presidential line of succession, which, according to the Defense Code, is the President of the Senate followed by the Prime Minister. In the event all three offices become simultaneously vacant, the authority to order a nuclear strike is transferred to a person whose identity remains classified. The Chief of the Military Staff of the President of the Republic is tasked with assisting the President in ordering the strike.

Under duress, the President can transmit a counterfeit code to let the receiving military officer know not to execute the strike.

Jupiter Command Post

The Jupiter Command Post (Poste de commandement Jupiter, PC Jupiter) is a structure in the bunker of the Élysée Palace equipped to enable the French president and his advisers to manage crisis situations and maintain contact with other government entities, military command posts, and foreign governments.

The main mission of this specific branch is to secure the government's control over all the nuclear forces and weapons. More specifically, the gendarmes of this unit are responsible for ensuring the protection and the readiness of the different kinds of missiles used by the French Navy and Air Force.

In order to do so, the GSAN is composed of its own units and of units from other branches of the gendarmerie, temporarily placed under its command like squadrons of the Mobile Gendarmerie to protect the convoys of nuclear weapons components.

Forward nuclear deterrence

In March 2026, France offered to extend ‌the ⁠protection of its nuclear umbrella to other European countries amid heightened tensions with Russia and doubts about long-term U.S. security guarantees. Under the scheme, members may temporarily host French nuclear armed "strategic air forces", conduct joint nuclear drills, and coordinate on collective security. As of May 2026, nine nations have joined the initiative: Belgium, Denmark, Germany, Greece, the Netherlands, Norway, Poland, Sweden and fellow nuclear power the United Kingdom.
