Lethal Range of Wigwam Targets Based on Hull Response and Applied Pressure Measurements
Abstract
The external pressures applied to the three SQUAW targets in Operation Wigwam were measured with pressure gages, and the deformations of the hull were measured with strain and displacement gages. The results indicate that SQUAW-12 was at a horizontal range of 5150 ft and a depth of 290 ft; the peak shock pressure at the hull was about 850 psi and the target destroyed, probably within 10 msec. SQUAW-13 was at a horizontal range of 7200 ft and a depth of 260 ft; the peak dynamic pressure at the hull was about 615 psi, and the hull was probably near collapse but did not rupture. The estimation is that the lethal horizontal range of the SQUAW target under the Wigwam test conditions is about 7000 ft for a depth of 250 ft and about 4500 ft for a depth of 70 ft.
