IMX-101 costs more than TNT, but the more the military buys the cheaper it gets, and that economies of scale may further accelerate its adoption in other large-caliber munitions. Having a less volatile explosive means the military can store more of the stuff in one place and transport more of it in any given vehicle than they could previously. That cuts down on supply chain problems and logistical headaches, not to mention the vulnerability of convoys delivering the goods in combat zones.
