In an instrumented test in September 1975 at the Naval Weapons Center, approximately 37,000 pounds (16 783 kilograms) of trinitrotoluene (TNT) explosive contained in a hemisphere built of 8-pound (3.6-kilogram) blocks were detonated by means of an initiation system located at the center of the base of the hemisphere. The principal objective was to demonstrate the resistance of a newly designed headwall and door combination to blast simulating that possible at the minimum front-to-rear spacing now permitted for standard earth-covered magazines. The test demonstrated this headwall and door design to be well balanced and completely effective in preventing communication of explosion between magazines in a front-to-rear exposure at a distance in feet of 2.0 x cube root of W, where W is the weight in pounds of the high explosive that detonates. Additionally, the results confirmed the ability of the single-leaf, sliding door to maintain its structural integrity whether mounted on a new structure or on an existing headwall. The results also demonstrated an imbalance in strength between this door and the existing headwalls built according to OCE standard drawing 33-15-64. The report contains data on igloo damage and structural motion and air-blast measurements at the site.
