Timing and Firing: Operation Tumbler-Snapper

Abstract

The contractor was commissioned to do the following tasks as part of the timing and firing functions on Tumbler-Snapper (April to June 1952). (1) Generate and distribute predetonation timing signals for all shots-four airdrops and four tower shots. (2) Install and operate switching relays connected to the timing circuits at the various experimental locations. (3) Install and operate the bomb-firing and monitoring circuits for nonairdrops. (4) Determine the time of detonation with respect to world time. (5) Determine, for airdrops, the time of fall. (6) Generate and deliver to the Communications Group a 1000-cycle tone keyed to a specified code. (7) Telemeter, record, and indicate meteorological data. (8) Provide photocell-actuated Blue Box fiducial markers for various experiments to give millisecond accuracy to zero time signals. (9) Provide timing dry runs for the benefit of experiments twice daily and more often if required. (10) Provide personnel to serve as member of the Firing Team as directed by the Test Director. Five major stations were operated (one Control Point and four switching stations), and upward of 500 separate signals were operated at about 200 separate locations.
