“Dedicated Navy divers, demolition teams, and high-powered sonar spent weeks searching the ocean floor and came up empty.”

Throughout history, the idea of misplacing a nuclear weapon may sound like a plot twist in an espionage novel. The United States has experienced more than a handful of such incidents. Known as “Broken Arrows,” these events typically refer to any accidents involving nuclear weapons that do not pose an immediate risk of triggering a nuclear war.
For decades, details remained hidden behind top-secret clearances. However, unclassified records reveal that the U.S. military has had a surprising number of mishaps, with some bombs still unaccounted for to this day.
What are broken arrows?
The Department of Defense defines a “Broken Arrow” as any incident involving a U.S. nuclear weapon or warhead that results in accidental launching, firing, detonating, theft, or loss of the weapon. From 1950 to 1980, official sources cite 32 Broken Arrow incidents, but there may have been more, given the secrecy surrounding nuclear matters.
