Shots
Distant Zenith
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.
