A $13 Defense Against Drone Swarms
The United Kingdom’s Ministry of Defence will deploy the DragonFire laser-directed energy weapon (LDEW) aboard Royal Navy destroyers by 2027. This timeline positions the UK as the first European NATO member to field an operational shipborne laser weapon.
The system is designed to provide a high-precision, low-cost defensive layer against drone swarms and other aerial threats. By utilizing concentrated light energy, the weapon eliminates the need for expensive interceptor missiles, which can cost hundreds of thousands of dollars per unit.
From Prototype to Maritime Service
Following successful land-based trials, the Royal Navy is moving to integrate the technology into its fleet. During a NATO industry forum held last week in Portsmouth, officials and industry partners discussed the transition from prototype status to active maritime service.

The move represents a shift in naval defensive doctrine. It prioritizes sustainment and ammunition cost-efficiency in environments where drone saturation is increasingly common.
Unlimited Capacity at the Speed of Light
The $13-per-shot estimate reflects the cost of electricity required to fire the laser, excluding the initial capital expenditure of the platform. Unlike traditional point-defense systems, such as the Phalanx Close-In Weapon System (CIWS), DragonFire does not require a physical magazine.
This allows for theoretically unlimited engagement capacity, provided the vessel maintains a consistent power supply. Because the system tracks and targets at the speed of light, it offers a distinct advantage against low-cost, expendable unmanned aerial vehicles (UAVs).
Logistical Shifts in Naval Warfare
While traditional kinetic interceptors remain necessary for hardened targets, the Ministry of Defence views directed-energy weapons as a primary tool for mitigating the logistical burden of maintaining large stockpiles of defensive munitions. The UK’s procurement schedule places it at the forefront of European directed-energy development, moving ahead of the various test programs conducted by the United States and Germany.
Integration Challenges and Fleet Readiness
The British government has not yet specified which class of destroyer will receive the first installation, though integration assessments are currently underway. The Ministry of Defence is in the final stages of evaluating the hardening requirements for the weapon’s power management and cooling systems to ensure compatibility with existing warship infrastructure.
