Nuclear Notebook: How many nuclear weapons does France have?

France’s nuclear arsenal contains approximately 300 warheads, a number that has remained stable over the past decade. Nearly all of these warheads are deployed or operationally available for deployment on short notice. A small number of additional warheads are in maintenance.

Other than the United States, France is the most transparent of the nuclear-armed states, having disclosed details about its nuclear forces and operations for many years. The current force level is the result of adjustments made to France’s nuclear posture following former President Nicolas Sarkozy’s announcement on March 21, 2008 that the arsenal would be reduced to fewer than 300 warheads (Sarkozy 2008). Former President François Hollande reaffirmed this posture on February 19, 2015, when he declared that France had a stockpile of 300 warheads for “three sets of 16 submarine-based missiles and 54 ASMPA [air-launched] delivery systems,” which together provide France with both strategic and tactical nuclear capabilities (Hollande 2015)…

In August 1945, the United States used nuclear bombs on the Japanese cities of Hiroshima and Nagasaki. It was the first and remains the last time that nuclear weapons have been used in war. The story of how those bombs were made, the decision to use them, and the effects on Japan and its people have been central to conversations around nuclear weapons ever since. To mark 81 years since that August, the Bulletin is bringing together three storytellers who have engaged with that history in diverse ways to talk about what happened, what society remembers (and what it doesn’t), and why telling these stories is still crucial more than eight decades into the nuclear era. Join us on August 18 at 10:15 a.m. CT for this Bulletin virtual event.
