Five new explosive formulations were screened for possible use in foxhole digging. Three of them were based on nitromethanenitroethaneRDX NM NERDX, with viscosities varying from liquid through slurry to paste. The other formulations were 1 a two-part gelled slurry mix, DBA-208X, submitted by the IRECO Chemical Corporation, and 2 a two-part liquid formulation, LLTX G-2, submitted by the Explosives Corporation of America EXCOA. After testing, the liquid NMNERDX was selected as the most promising formulation for fulfilling the requirements of ENSURE 279-K because of its superior handling, performance, and sensitivity characteristics, as well as its moderate cost. Suggestions for improving the use of liquid explosives in cratering are also given. Finally, the 3.5-in. M28A2 HEAT rocket warhead is evaluated for its capability to produce boreholes in permafrost as a prerequisite for placing explosive cratering charges.
