Operation Tumbler–Snapper was a series of atomic tests conducted by the United States in early 1952 at the Nevada Test Site. The Tumbler-Snapper series of tests followed Operation Buster-Jangle, and preceded Operation Ivy.

The Tumbler phase, sponsored by the Atomic Energy Commission consisted of three airdrops which were intended to help explain discrepancies in the actual and estimated blast shock wave damage noted on previous detonations, and to establish more accurately the optimum height of burst.

The Snapper phase, sponsored by the Department of Defense consisted of one airdrop and four tower shots intended to test various new weapons developments.

The military exercise Desert Rock IV, involving 7350 soldiers, took place during the test series. They trained during the Charlie, Dog, and George shots and observed shot Fox.
