Although modern warfare has evolved rapidly due to the proliferation of unmanned systems, precision weapons are the future of the battlefield. Independent strike capabilities are critical to the US and allied war efforts, allowing for the defeat of high-value enemy military assets and infrastructure at much lower costs than traditional methods and with significantly reduced collateral damage. Recognizing the critical need for these capabilities, Heaviside develops precision explosives designed to operate in competitive environments—where legacy systems degrade or fail—without increasing cost or sacrificing performance.
