The long-term goals of the research were 1 to establish vulnerability of finite concrete targets to a variety of warhead technologies, 2 to develop a damage rule which relates obstacle destruction to warhead and obstacle characteristics, and 3 to ultimately understand the ordnance options to break up the concrete blocks into pieces with maximum standing dimensions that will not impede the advance of an Amphibious Assault Vehicle AAV. The objectives of the FY98 effort were to wrap up the five-year concrete target vulnerability work with an experimental program that would broaden our assessment of two warhead types against finite concrete obstacles by including the effect of submergence under water. A direct comparison to the break up in air could be made since identical warheads as used in the FY96 and FY97 test program were tested. The warheads planned for the FY98 testing were explosively-formed projectiles EFPs available from the lot specially designed by, and procured from, DE Technologies, Inc. DET for the FY96 and FY97 test program and a 3200 grft CuRDX linear-shaped charge LSC originally procured from GOEX International. As detailed below, these objectives have been met.
