Nuclear Weapons Accidents
Since 1950, a total of 32 U.S. nuclear weapons accidents are
known to have occurred resulting in the loss or destruction of nuclear warheads.
Most of these accidents involved a single warhead an onboard aircraft that
crashed or a missile that blew up, but some accidents destroyed up to four
The most recent known accident occurred in 1980 when a nine
megaton warhead was blown out of an ICBM silo in Arkansas when missile fuel
vapors ignited and exploded.
U.S. Air Force bombers no longer fly with live nuclear
weapons, but thousands of nuclear warheads are still on alert on top of
potentially volatile missiles. Nuclear warheads are frequently transported on
military cargo aircraft and trucks within the United States and to forward
deployed locations in Europe.
