Operation Tumbler–Snapper was a group of nuclear weapons tests carried out by the United States. These tests happened in early 1952 at the Nevada Test Site. This series of tests came after Operation Buster–Jangle and before Operation Ivy.

Understanding the Tests

The Tumbler Phase

The first part of the tests was called Tumbler. The Atomic Energy Commission was in charge of this phase. It included three tests where bombs were dropped from planes. The main goal was to understand how the shock waves from explosions caused damage. Scientists wanted to figure out the best height for a bomb to explode to get the most impact.

The Snapper Phase

The second part was called Snapper. The Department of Defense led this phase. It involved one bomb dropped from a plane and four bombs set off on tall towers. These tests were designed to try out new ideas for nuclear weapons.

During these tests, a military exercise called Desert Rock IV also took place. About 7,350 soldiers participated. They trained during some of the explosions, known as the Charlie, Dog, and George shots. They also watched the Fox shot.

What Happened After the Tests?

US nuclear test exposure
This chart shows the ten highest radiation exposures to people from US nuclear tests on land. The shot named George is in the first column.

Some of the Tumbler-Snapper explosions created a lot of fallout. Fallout is radioactive dust that spreads after a nuclear explosion. One test, called George, caused more people to be exposed to radiation than any other nuclear test in the United States. The George test alone was responsible for about 7% of all the radiation exposure to people during the 1,032 nuclear tests done by the U.S.
