Abstract : Edgerton, Germeshausen and Grier, Inc. (EG&G) furnished timing and firing signals for the thirty-seven shots of Operation Hardtack, Phase II. Six independent timing systems were installed in the CP-l building and in five timing signal distribution stations at the Nevada Test Site. Signals from the sequence timers were distributed to experimenters and to zero sites by wire; voice-time announcements were transmitted to experimenters on radio frequencies. The world-time system was operated on surface, tower, and balloon shots and on certain of the underground detonations. Most of the above-ground shots were instrumented for Bhangmeter recording.
