Abstract:

The original objectives of this experiment were to determine the effects of very high-altitude, large-yield nuclear detonations on the ionosphere and on signals propagated via the ionosphere. However, the location of the Teak and Orange Shots was changed and it was not possible to obtain suitable project sites. Therefore, the original objectives no longer applied and the experiment became an attempt to increase the store of knowledge about ionospheric effects of large-yield ground-level detonations using the sites that had already been instrumented for Teak and Orange. It is recommended that any future project of this type that might operate at a site where commercial power is not available, furnish its own run-in diesel generators, including 100 percent backup, all necessary maintenance supplies, and transfer pump with fuel line fittings.
