In October 1983, DIRECT COURSE, the worlds largest non-nuclear height-of-burst HOB event took place. In June 1985, MINOR SCALE, the worlds largest 8KT equivalent non-nuclear surface event, took place. These two events represented a marked departure from the earlier rather standard and sporadic 1 KT equivalent surface events conducted by the Defense Nuclear Agency DNA. By developing these two new techniques as viable simulations, DNA has opened the door to further phenomonology research and airblast effects testing on a scale not previously attainable. The 1 KT equivalent HOB technique offered the opportunity to examine on a large scale, the phenomonology associated with the regular reflection, irregular Mach reflection, and regular Mach reflection regions together with the associated flow fields, both dusty and clean. The greater than 1 KT technique afforded an opportunity to examine structures, weapons systems, etc. at a significantly different impluse level than that previously available. This paper will review the two new techniques and assess their simulation fidelity.
