UK to Deploy $13 Laser Weapon on Royal Navy Destroyers by 2027

The United Kingdom will install a laser weapon system capable of destroying drones for approximately $13 per shot aboard Royal Navy destroyers by 2027, according to reporting from The Defence Blog. This deployment would make the UK the first European NATO member to field an operational shipborne directed-energy weapon.

The system’s developers presented the technology at a NATO industry forum in Portsmouth during the week of June 20, 2026. The weapon uses a high-energy beam to disable or destroy aerial targets, providing a low-cost alternative to traditional missile-based air defense.

How does the laser weapon reduce defense costs?

The primary advantage of the system is its cost-efficiency. While traditional interceptor missiles can cost millions of dollars per unit, the laser weapon requires only electricity to fire. The Defence Blog reports the cost per shot is roughly $13.

This price point allows the Royal Navy to engage low-cost threats, such as small drones, without depleting expensive missile stockpiles. The beam travels at the speed of light, removing the need for the lead-time calculations required for kinetic projectiles.

What is the timeline for Royal Navy deployment?

The UK government expects the system to be operational on destroyers by 2027. These ships serve as the primary air-defense escorts for the Royal Navy’s aircraft carriers.

The transition to shipborne deployment follows a series of land-based trials. The Ministry of Defence has previously tested the system’s ability to track and neutralize targets with high precision over long distances.

Why is this significant for NATO?

The deployment marks a shift in European naval capabilities. By fielding an operational directed-energy weapon (DEW) at sea, the UK becomes the first European member of the NATO alliance to do so.

This capability addresses the increasing threat of “drone swarms,” where numerous inexpensive unmanned aerial vehicles (UAVs) attempt to overwhelm a ship’s defenses. A laser system can engage multiple targets in rapid succession as long as it has a power source, unlike missile launchers which have a finite number of rounds before requiring a reload.

How does the system compare to traditional defenses?

Traditional air defense relies on kinetic energy, using missiles or guns to physically strike a target. These systems are limited by magazine capacity and the high cost of each interceptor.

The laser system offers a contrast in both logistics and economics. It eliminates the need for storing and transporting volatile missiles on deck and reduces the financial burden of engaging low-value targets. According to the technical details shared at the Portsmouth forum, the system’s precision allows it to target specific critical components of a drone to cause immediate failure.

The Royal Navy’s move toward directed energy reflects a broader trend in global military procurement to counter asymmetric threats from low-cost autonomous systems.
