Operation Anadyr was the code name used by the Soviet Union for its Cold War secret operation in 1962 of deploying ballistic missiles, medium-range bombers, and a division of mechanized infantry to Cuba to create an army group that would be able to prevent an invasion of the island by United States forces. The plan was to deploy approximately 60,000 personnel in support of the main missile force, which consisted of three R-12 missile regiments and two R-14 missile regiments. However, part of it was foiled when the United States discovered the plan, prompting the Cuban Missile Crisis.

The Cuban Missile Crisis, also known as the October Crisis in Cuba, or the Caribbean Crisis, was a 13-day confrontation between the governments of the United States and the Soviet Union, when American deployments of nuclear missiles in Italy and Turkey were matched by Soviet deployments of nuclear missiles in Cuba. The crisis lasted from 16 to 28 October 1962. The confrontation is widely considered the closest the Cold War came to escalating into full-scale nuclear war.
