At 12:12 am EDT, on October 27, the US informed its NATO allies that "the situation is growing shorter.... the United States may find it necessary within a very short time in its interest and that of its fellow nations in the Western Hemisphere to take whatever military action may be necessary." To add to the concern, at 6:00 am, the CIA reported that all missiles in Cuba were ready for action.

On October 27, Khrushchev also received a letter from Castro, what is now known as the Armageddon Letter (dated the day before), which was interpreted as urging the use of nuclear force in the event of an attack on Cuba: "I believe the imperialists' aggressiveness is extremely dangerous and if they actually carry out the brutal act of invading Cuba in violation of international law and morality, that would be the moment to eliminate such danger forever through an act of clear legitimate defense, however harsh and terrible the solution would be," Castro wrote.

Later that same day, what the White House later called "Black Saturday", the US Navy dropped a series of "signalling" depth charges (practice depth charges the size of hand grenades) on a Soviet submarine (B-59) at the blockade line, unaware that it was armed with a nuclear-tipped torpedo with orders that allowed it to be used if the submarine was damaged by depth charges or surface fire.[147] As the submarine was too deep to monitor any radio traffic, the captain of the B-59, Valentin Grigoryevich Savitsky, decided that a war might already have started and wanted to launch a nuclear torpedo. The decision to launch these normally only required agreement from the two commanding officers on board, the Captain and the Political Officer. However, the commander of the submarine Flotilla, Vasily Arkhipov, was aboard B-59 and so he also had to agree. Arkhipov objected and so the nuclear launch was narrowly averted.

On the same day a U-2 spy plane made an accidental, unauthorised ninety-minute overflight of the Soviet Union's far eastern coast. The Soviets responded by scrambling MiG fighters from Wrangel Island; in turn, the Americans launched F-102 fighters armed with nuclear air-to-air missiles over the Bering Sea.

Later revelations

Submarine close call

Arguably, the most dangerous moment in the crisis was not recognized until the Cuban Missile Crisis Havana conference, in October 2002. Attended by many of the veterans of the crisis, they all learned that on October 27, 1962, USS Beale had tracked and dropped signalling depth charges (the size of hand grenades) on B-59, a Soviet Project 641 (NATO designation Foxtrot) submarine. Unknown to the US, it was armed with a 15-kiloton nuclear torpedo. Running out of air, the Soviet submarine was surrounded by American warships and desperately needed to surface. An argument broke out among three officers aboard B-59, including submarine captain Valentin Savitsky, political officer Ivan Semyonovich Maslennikov, and Deputy brigade commander Captain 2nd rank (US Navy Commander rank equivalent) Vasily Arkhipov. An exhausted Savitsky became furious and ordered that the nuclear torpedo on board be made combat ready. Accounts differ about whether Arkhipov convinced Savitsky not to make the attack or whether Savitsky himself finally concluded that the only reasonable choice left open to him was to come to the surface.  During the conference, McNamara stated that nuclear war had come much closer than people had thought. Thomas Blanton, director of the National Security Archive, said, "A guy called Vasily Arkhipov saved the world."
