Abstract : The use of Minol-II as an emergency substitute for Tritonal in the Mk 82 and M117 general purpose bombs was studied. One of the principal areas of concern in the use of Minol-II filled bombs is that the volume of the explosive apparently increases during temperature cycling. For this reason, a study is recommended to determine the effect of long term storage. The safety tests seemed to indicate that Minol-II is no more hazardous than Tritonal or H-6. Performance tests indicate that Minol-II is better than Tritonal although not as powerful as H-6. Minol II did fail the 20 mm AP bullet impact test, however, H-6 and Tritonal will not pass this very severe test either. Although Minol-II was primarily considered on an emergency basis because of a shortage of TNT there is a distinct possibility that a permanent substitution should be considered. The cost advantage of ammonium nitrate over TNT is considerable. It might be possible to modify the phase transitions of ammonium nitrate in such a way as to eliminate one of the principal objections to its use.
