Directed energy weapons have been “just around the corner” for so long that healthy scepticism has become the default response to any announcement in the field. DragonFire, MBDA’s high-energy laser weapon developed for the UK armed forces, has spent years in that uncomfortable position – genuinely impressive in trials, but with an operational deployment date that kept sliding rightward.
In March 2026, that changed. The Minister for Defence confirmed the acceleration of DragonFire’s deployment onto Royal Navy Type 45 destroyers by 2027 – a reduction of approximately five years compared to earlier planning timelines (that’s not something you hear often). A £316 million production contract was awarded to MBDA in November 2025. The first installations are expected on at least two Type 45s, using feeds from the ships’ Sampson radar to acquire and engage targets.

What DragonFire actually does
DragonFire is a 50-kilowatt high-energy laser weapon, designed primarily to counter drone and missile threats at a cost that conventional weapon systems struggle to match. Its two headline statistics say it all: it costs around £10 per shot, and it is accurate enough to hit a £1 coin from a kilometre away.
The system uses UK-developed Coherent Beam Combination technology, which merges multiple glass-fibre laser sources into a single high-quality beam. Unlike some competing laser programmes, the technical approach is genuinely British – developed by MBDA, Leonardo, and QinetiQ, manufactured domestically. It is not an off-the-shelf American system with UK markings.
Recent trials at the MOD’s Hebrides range demonstrated tracking, targeting, and destroying drones flying at speeds up to 650km/h – twice the top speed of a Formula 1 car. A UK first was also achieved during those trials: above-the-horizon tracking of a target, expanding the effective engagement envelope.
Why the Type 45 is the right first platform
The Type 45 Daring-class destroyers are the Royal Navy’s primary air defence platforms, built around the Sea Viper missile system using Aster 15 and Aster 30 missiles. They are highly capable but face a fundamental challenge that has become increasingly acute in modern warfare: missile magazines run out. A ship that expends its Aster missiles defending against a drone swarm may have nothing left for the high-end threat that follows.
DragonFire addresses this directly. A laser weapon draws from the ship’s power supply rather than a finite magazine. As long as the propulsion system is generating power, the weapon can keep firing. Against drone threats specifically – which have proliferated to the point where swarm attacks are now a realistic tactical challenge – a power-magazine weapon is a transformative capability.
The Sampson radar’s integration with DragonFire is also significant. Sampson is one of the most capable naval radars in the world, capable of tracking hundreds of targets simultaneously. Pairing it with a directed-energy weapon creates an engagement system that can rapidly and precisely engage multiple targets in quick succession.
The bigger picture
The UK has been somewhat coy about its directed energy ambitions, but DragonFire’s acceleration suggests that the MoD is treating it as a genuine operational capability rather than a technology demonstrator. The five-year compression in the deployment timeline is remarkable – it implies that the Hebrides trials went significantly better than the original plan anticipated.
With the Type 83 destroyer cancelled and the Type 45s now expected to serve into the 2040s, fitting DragonFire to those ageing hulls is also a sensible way of maintaining their relevance against an evolving threat environment. It won’t make an old ship young. But it will make it substantially harder to attack cheaply.
