US firm develops high capacity battery for next-gen laser weapons

KULR Technology, a US-based company, has developed a next-generation 400V rugged battery prototype designed to power high-power laser weapons, particularly for counter-drone (Counter-UAS) applications. The Houston firm completed the prototype in just five weeks using in-house testing and advanced engineering methodologies, including model-based electrical and thermal simulations, proprietary cell selection, and a design-for-safety architecture. The battery is engineered to withstand harsh operational conditions and meet the rigorous MIL-STD-810H military standards. Production is planned to begin in 2026 as part of an expansion of KULR’s defense-focused KULR ONE Guardian (K1G) platform. The development comes amid a rising global demand for counter-drone systems, as drones have become a significant threat in modern warfare for surveillance, reconnaissance, and strikes. The directed energy weapons market is projected to grow from $7.9 billion to nearly $40 billion over the next decade, driven by increased defense budgets and modernization efforts
