Chariot Defense’s M424 hybrid system delivered 36 hours of low-signature power as Army leaders push faster procurement and U.S. battery production.
Chariot Defense founder and CEO Adam Warmoth and U.S. Army CTO Alex Miller explain why modern, distributed warfare needs a new tactical power layer. Soldiers can draw 30–60 watts continuously, while legacy generators sized for peak demand create heat, noise, fuel burdens and detectable signatures. Chariot’s M424 combines batteries, power electronics and controls to buffer surges, provide clean power and let generators shut down; a reconnaissance company ran radios, electronic warfare equipment and drones for 36 hours without detectable thermal or acoustic output. Miller describes Army experiments that shrink command posts and put technology in soldiers’ hands sooner, replacing years of requirements-writing with field feedback and outcome-focused acquisition. The Army is consolidating acquisition portfolios and investing with the Department of Energy in domestic battery manufacturing, while Warmoth says defense demand can help U.S. suppliers move down the cost curve. Their goal: make power reliable and interoperable enough that soldiers can focus on the mission, not charging batteries.
