Thank you Vasili Arkhipov, the man who stopped nuclear war

Fifty years ago, Arkhipov, a senior officer on the Soviet B-59 submarine, refused permission to launch its nuclear torpedo.

Edward Wilson in The Guardian:

If you were born before 27 October 1962, Vasili Alexandrovich Arkhipov saved your life. It was the most dangerous day in history. An American spy plane had been shot down over Cuba while another U2 had got lost and strayed into Soviet airspace. As these dramas ratcheted tensions beyond breaking point, an American destroyer, the USS Beale, began to drop depth charges on the B-59, a Soviet submarine armed with a nuclear weapon.

The captain of the B-59, Valentin Savitsky, had no way of knowing that the depth charges were non-lethal "practice" rounds intended as warning shots to force the B-59 to surface. The Beale was joined by other US destroyers who piled in to pummel the submerged B-59 with more explosives. The exhausted Savitsky assumed that his submarine was doomed and that world war three had broken out. He ordered the B-59's ten kiloton nuclear torpedo to be prepared for firing. Its target was the USS Randolf, the giant aircraft carrier leading the task force.

If the B-59's torpedo had vaporised the Randolf, the nuclear clouds would quickly have spread from sea to land. The first targets would have been Moscow, London, the airbases of East Anglia and troop concentrations in Germany. The next wave of bombs would have wiped out "economic targets", a euphemism for civilian populations – more than half the UK population would have died. Meanwhile, the Pentagon's SIOP, Single Integrated Operational Plan – a doomsday scenario that echoed Dr Strangelove's orgiastic Götterdämmerung – would have hurled 5,500 nuclear weapons against a thousand targets, including ones in non-belligerent states such as Albania and China.
