Raduga (in Russian Радуга, Rainbow) is the codename of a Soviet thermonuclear test, conducted in October 20, 1961, in Mityushikha Bay, Severny Island of Novaya Zemlya.

The test was realized by the Northern Fleet. A R-13 rocket with a thermonuclear warhead was fired from a submarine K-102. When the submarine reached the specified point in the Barents Sea, she could not clarify her position due to cloudiness and snowfall. Firstly the shot an R-13 rocket without nuclear warheads, which fell to a strong deviation from the testing ground. However, it was decided to continue the experiment in spite of bad weather. The next rocket reached the target point with a deviation less than the previous one, exploded at 1000 m height and released an energy of 1450 kilotons.
