The Soviet submarine officer who single-handedly prevented a nuclear strike during the Cuban Missile Crisis

In short: In October 1962, a Soviet submarine commander, isolated and under fire, ordered the launch of a nuclear torpedo against the US Navy. He believed World War III had begun. Only the intervention of one man, Vasily Arkhipov, prevented the launch, potentially saving the world from a catastrophic nuclear exchange.

During the Cuban Missile Crisis, the Soviet submarine B-59 was part of a secret deployment to Cuba. On October 27, 1962, while operating in the Sargasso Sea, the vessel was hunted by US Navy forces using "hunt to exhaustion" tactics. The submarine had been out of contact with Moscow for days, and the crew, suffering from extreme heat, high CO2 levels, and exhaustion, believed they were under attack and that war had likely broken out.

The submarine's captain, Valentin Grigoryevich Savitsky, was pushed to his limit by the relentless pressure from US destroyers and aircraft. When the vessel was hit by signalling depth charges, Savitsky ordered his crew to prepare a nuclear-tipped torpedo for launch. Under the specific command structure of the B-59, the authority to fire this weapon required the unanimous consent of three officers: the captain, the political officer, and the chief of staff, Vasily Arkhipov.

While the captain and political officer were reportedly in favor of the launch, Arkhipov refused to give his consent. He successfully persuaded Savitsky to surface the submarine instead of engaging. At the time, the US Navy was entirely unaware that the submarine carried a nuclear weapon with the approximate power of the Hiroshima bomb. It was not until a 2002 conference marking the 40th anniversary of the crisis that the full extent of this near-miss was publicly recognized, with observers later noting that Arkhipov's decision had effectively averted a global catastrophe.
