The Naval Explosive Ordnance Disposal Facility conducted tests to determine the cutting and penetration effects of 20-,30-,40-,60-,75-,125-,225-, 300-,400-,500-, and 600-grain-per-foot lead-sheathed flexible linear shaped charges FLSCs filled with CH-6 explosive, for use as a general-purpose tool by joint-service explosive ordnance disposal personnel. Tests were conducted on 25-millimeter-thick 1-inch-thick aluminum 2024-T4, 51-millimeter-thick 2- inch-thick aluminum 2024-T351, and 25- and 51-millimeter 1- and 2inch- thick mild steel 1018 witness plates, both with and without standoff material. In addition to the FLSC tests, tests were conducted on the same type of witness plates using Mk 8 Mod 2 and Mk 7 Mods 1 through 8 linear shaped-charge containers, hand packed with composition C-4 explosive, to document and compare their cutting and penetration effects with those of the FLSCs. The results of the tests indicate the flexible linear shaped charges filled with CH- 6 explosive are superior to comparable Mk 7 linear shaped charges due to their wider range in sizes. Also, the Mk 7 linear shaped-charge containers suffer from problems encountered in hand packing explosive in cold weather inconsistency between individual packers and rigid construction, which causes problems in placement on curved or bent surfaces.
