France to Boost Nuclear Arsenal, Involve Allies
President Macron announced France will increase the size of its nuclear arsenal and, in an unprecedented move, allow temporary deployment of nuclear-armed jets to allied European nations. The decision marks a significant geopolitical pivot, aiming to bolster France's role in European security.
France's nuclear doctrine has historically emphasized "strict sufficiency," maintaining the smallest possible arsenal for a credible deterrent. The country's stockpile peaked at 540 warheads toward the end of the Cold War and has been nearly halved since. President Macron's decision to increase the arsenal for the first time in decades marks a significant departure from this long-standing policy, though the new total will remain confidential. This strategic shift is underpinned by a significant investment in modernization. The nuclear deterrent currently accounts for 13% of France's defense budget, a figure expected to reach €57.1 billion ($61.7 billion) by 2026. Key upgrades include the new M51.3 submarine-launched ballistic missile, with a range of up to 10,000 km, and the development of the ASN4G air-launched hypersonic missile, designed to fly at over Mach 6. The new "forward deterrence" policy will involve eight other European nations in discussions and exercises: Belgium, Denmark, Germany, Greece, the Netherlands, Poland, Sweden, and the United Kingdom. This could see French nuclear-capable Rafale jets temporarily stationed on allied territory for the first time, a move intended to "complicate the calculations of our adversaries." While allies will participate in exercises, the ultimate decision to use nuclear weapons remains solely with the French president. Initial reactions from partners have been positive, with Germany agreeing to conventional forces participating in French nuclear drills and Poland's Prime Minister confirming talks on the advanced deterrence program. France's nuclear posture has always been independent from NATO's integrated military command. A founding member of the alliance, France, under Charles de Gaulle, withdrew from the command structure in 1966 to maintain strategic autonomy, and to this day, it does not participate in NATO's Nuclear Planning Group. This new "Europeanized" deterrence effort is presented as complementary to, not a replacement for, NATO's security architecture.
