Book excerpt: Because of the large number of ships crippled by indirect detonations during World War II, the U.S. Navy took an interest in underwater explosion phenomena. To ensure future ship survivability, Navy rules soon dictated that the first ship in every new class or flight would be subjected to ship shock test trials. The Navy selected the Arleigh Burke class destroyer, USS WINSTON S. CHURCHILL (DDG-81), as the most recent platform and subjected it to an underwater explosion two-thirds the magnitude of the design level shot. Actual detonation of the design level shot was not conducted due to the high risk of failure. This thesis predicts the effects of the full design level shot and investigates its relationship to the two-thirds shot data. An additional study was done to see how the effects of the design shot would be altered if a combination of the standoff distance, angle of attack, and charge size was modified while keeping a constant shock magnitude. The findings show that the effects of the design shot are the same regardless of position and charge weight as long as the shock magnitude is kept constant. This is an important finding because the design shot can be achieved using a variety of attack geometries and charge sizes. (1 table, 68 figures, 23 refs.).
