Subfile: ERA (Energy Research Abstracts). Country of Origin: United States GRA (NTIS NTS) Country of Publication: United States Abstract: On Operation Hardtack, arming and firing signals for 35 devices in addition to a sequence of timing signals for the experimental programs aré presented. Also, a voice countdown on all dry runs and detonations, monitoring vital information, and determining, where practicable, the time of burst and the Bhangmeter yield is included. The complexity of the shot schedule, which involved several differing modes of detonation, necessitated a multiple timing and firing installation comprising seven independent systems; three were operated from Eniwetok, two from Bikini, one on the USS Boxer, and one on Johnston Island (Operation Newsreel). Besides the four control centers, the timing and firing complex included nine island-based, signal distribution stations, as well as several shipboard stations. A versatile timing system was devised for this operation which employed a coder-decoder combination capable of transmitting twenty-four signals. Signals were transmitted by telephone line or on radio frequencies as dictated by the individual shot requirements. The timing and firing system operated accurately and reliably, transmitted.
