# DragonFire (weapon)

DragonFire is a British laser directed-energy weapon (LDEW). It was first unveiled to the public as a technology demonstrator in 2017 at the Defence and Security Equipment International (DSEI) conference in London and is being developed by UK DragonFire, a collaboration consisting of MBDA UK, Leonardo UK, QinetiQ and the Defence Science and Technology Laboratory (dstl). A production version is expected to enter service in 2027 onboard Royal Navy ships.

## Development

The weapon was first shown publicly at the 2017 DSEI conference in London. Development of the technology demonstrator was to be carried out by a partnership between the British Ministry of Defence (MOD) and private industry. UK DragonFire is the result of contracts worth £100 million – of which £30 million was awarded by the MoD's Chief Scientific Advisor's Research Programme – from various companies, led by MBDA UK with QinetiQ, Leonardo, GKN, Arke, BAE Systems and Marshall Land Systems participating, to develop a technology demonstrator.
Trials were to begin in 2018, followed by a major demonstration in 2019; however, the COVID-19 pandemic and technical problems caused delays. It was ultimately deployed on trials in 2022 on the ranges in the Outer Hebrides in Scotland. According to MBDA, these initial low-power trials proved DragonFire's ability to track air and sea targets with exceptionally high accuracy. This was followed by high-power trials in November 2022, where the weapon engaged targets using its high-power laser in operationally representative scenarios. DragonFire engaged an airborne target in exercises in Scotland in January 2024. The MOD stated: "The range of DragonFire is classified, but it is a line-of-sight weapon and can engage with any visible target. The precision required is equivalent to hitting a £1 coin (23 mm) from a kilometre away." However according to an article on Freethink, "On November 8, 2022, it revealed that the $115 million laser weapon had been fired at high power at targets, including a drone and metals like the ones used in ship hulls, at ranges up to 2.1 miles." It has been tested against mortar rounds and drones, and fitted to a Wolfhound armoured vehicle. The UK MoD claims the firing of the weapon, for 10 seconds, only costs £10 per shot or the equivalent of running a heater for one hour.
In April 2024, the MOD announced that new procurement rules had increased the rate of development of the weapon and, as a result, it is expected to be in service onboard Royal Navy ships from 2027 instead of the originally planned 2032. UK Defence Secretary Grant Shapps stated that an early version of the weapon could be used by Ukraine against Russia as part of the Russo-Ukrainian War.

## Characteristics

DragonFire uses UK-pioneered beam-combining technology to deliver a laser beam with increased power density, reduced defeat times and increased effective range. This is achieved, in part, through the use of tens of glass fibres; however, the full technical approach remains classified. The laser and its associated targeting systems, including an electro-optical camera and second lower-power laser for imaging and tracking, are mounted to a turret. The laser is reportedly in the 50 kW class and is designed to defend land and maritime targets from threats such as missiles and mortar rounds. Its energy demands may be met by a Flywheel Energy Storage System (FESS), a joint UK–US innovation currently in development. The range of the weapon is undisclosed classified information. Cost per firing is very low; it has been stated as £10.
The UK envisages high-energy laser weapons, like DragonFire, onboard future Royal Navy warships, British Army armoured vehicles and fighter aircraft of the Royal Air Force, including the BAE Systems Tempest; it aims to demonstrate these concepts on board a Type 23 frigate and a Wolfhound armoured vehicle.
