Operation Touchstone


The United States's Touchstone nuclear test series was a group of 13 nuclear tests conducted in 1987-1988. These tests followed the Operation Musketeer series and preceded the Operation Cornerstone series.
The series included Touchstone Kearsarge, a joint US-Soviet test as part of the Joint Verification Experiment. The JVE's purpose was to provide yield data to both parties about each other's nuclear test sites so that accurate remote measurements could be taken to verify each other's compliance with the Threshold Test Ban Treaty.
