Abstract : A primary purpose of Operation Wigwam was to determine the effect the detonation of an atomic device at great depth would have on three submarine targets, called 'SQUAWS,' submerged to the same depth but at different distances from the device. In an attack on a submarine with an atomic device, as well as in an attack with a conventional weapon, the magnitude and character of the shock motions in the ship are functions of its depth and position relative to the device. The location and orientation of the SQUAW targets relative to the device would have to be known in order to evaluate fully the responses of the targets. Knowledge of the depth and orientation of each SQUAW was also required to guide in submergence and remote control of each target. A project was set up to measure and record the depth, angle of roll, angle of pitch, and heading of each SQUAW target. (Author)
