Abstract : The objectives of Project 3.1 were closely related to the tests of effects of underwater nuclear burst on ships to be conducted later in the summer of 1958 at the Eniwetok Proving Ground during Operation Hardtack. Thus, the main objectives of this project were to: (1) develop and check the tapered charge technique as a method of simulating and determining the effects of underwater nuclear detonations on ships; (2) provide a pretest experimental check on the target damage predictions in order that optimum placement of the ships targets could be achieved for the later Hardtack effort; and (3) calibrate instrumentation and check out the adequacy of the recording installations and shock mountings thereof designed by the various agencies for the later Hardtack effort. Keywords: Tapered Charges; Ships; Underwater Explosions.
