Period | 1990–1991 |
Number of tests | 7 |
Test type | underground shaft, tunnel |
Max. yield | 140 kilotonnes of TNT (590 TJ) |
Test series chronology | |
The United States's Sculpin nuclear test series [1] was a group of 7 nuclear tests conducted between October 1990 and September 1991. These tests [note 1] followed the Operation Aqueduct series and preceded the Operation Julin series.
Shot Distant Zenith included the experiment Hydroplus. The Defense Nuclear Agency (DNA) developed a means of verifying non-standard nuclear tests using ground peak stress and velocity at several ranges from a possible detonation point using computer hydrocodes. These codes required calibration data which was gathered at Distant Zenith. Further Hydroplus experiments were conducted in shot Hunters Trophy of Operation Julin. [2]
