Directed-Energy Weapon

An umbrella term for any weapon system that emits focused energy rather than firing projectiles. This includes lasers (electromagnetic radiation), microwave weapons (heating effects), particle beams (subatomic particles), and plasma weapons (ionized gas). Directed-energy weapons offer theoretical advantages: speed-of-light engagement (for lasers), deep magazines (power-limited rather than ammunition-limited), adjustable effects (from non-lethal to lethal), and reduced logistical burden. Operational systems include laser counter-drone weapons, microwave area-denial systems (Active Denial System), and research continues into higher-power systems for missile defense and anti-satellite roles. Directed-energy weapons represent a fundamental shift in warfare: from throwing things at the enemy to radiating them.
