On Oct. 1, 1962, U.S. intelligence alerts Defense Secretary Robert McNamara to the possibility that medium-range ballistic missiles have been positioned in Pinar del Río province, Cuba. The CIA also pinpoints San Cristóbal in Cuba, shown above, as a suspected medium-range ballistic missile (MRBM) site. McNamara then directs the heads of the U.S. Navy and Air Force to prepare for both a blockade and an airstrike against Cuba.
At the same time, the Soviet cargo ship Omsk leaves Nikolaev in the Black Sea, bound for Cuba with seven R-12 missiles.
