America has dropped at least two nuclear warheads on itself accidentally, which have all failed to detonate.
These are known as “Broken Arrow” incidents, and at least 32 have been officially recognized by the government. Some of them were accidental releases of the bombs, others were plane (or other vehicle) crashes that contained bombs. There’s likely more that haven’t been recognized by the government. almost all of them happened between 1950 and 1980. Now that the cold war has died down, we haven’t been moving around our nuclear warheads as often and so haven’t had a new one. At least, not an official new one.
At this point it’s pretty hard to have an accidental detonation at this point, though. Prompt criticality is tricky to achieve and easy to deliberately not achieve. Word is the newest bombs require a specific electronic sequence of fuse activations that’s stored encrypted, and would require being a superpower to reproduce, so it’s actually impossible to set them off as designed even if one was stolen.
