The bomb was tested on October 30, 1961, in Novaya Zemlya, an island in the Arctic Sea. The device was scaled down from its original design of 100 megatons to reduce the resulting nuclear fallout. Although the bomb was a 'light version' which would of allowed a yield of 150 megatons.

The fireball touched the ground, reached nearly as high as the altitude of the release plane, and was seen 1,000 km away. The heat could have caused third degree burns at a distance of 100 km. The subsequent mushroom cloud was about 60 km high and 30–40 km wide. The explosion could be seen and felt in Finland, even breaking windows there. Atmospheric focusing caused blast damage up to 1,000 km away. The seismic shock created by the detonation was measurable even on its third passage around the earth.
