Directed Energy Weapons and the Future of Military Power

Directed Energy Weapons (DEWs) are military systems that emit focused energy – such as high-power laser beams or microwaves – to disable or destroy targets without traditional munitions. After decades of research, DEWs are entering an emerging operational role in the 2025–2035 timeframe, with Western armed forces fielding demonstrators and initial systems.

The United States deployed the first operational laser weapon in 2014 aboard USS Ponce , and since then has accelerated development across all services. Key programs like the U.S. Navy’s HELIOS laser, the U.K.’s DragonFire laser, and the U.S.

This analysis answers: How do directed-energy weapons using high-power lasers and microwaves disable or destroy targets without traditional munitions? What operational role are DEWs entering in the 2025-2035 timeframe as Western forces field demonstrators and initial systems? How do programmes such as the US Navy HELIOS, the UK DragonFire and early operational systems mark the maturation of DEW capability? What are the doctrinal implications and strategic outlook for DEWs in the future of military power?
