The United Kingdom's Ministry of Defence has released a video of a firing exercise by its first-ever laser weapon - DragonFire.
The ministry said that the video was of the weapon's 'first high-power firing against an aerial target.'
It said that DragonFire was precise enough to hit £1 coin from a kilometre away
The test was conducted in January but the video was posted by the defence ministry on March 11.
The UK is looking at DragonFire as a low-cost alternative to missiles.
According to the UK goverment's website, 'the cost of operating the laser is typically less than £10 per shot.'
'The range of DragonFire is classified, but it is a line-of-sight weapon and can engage with any visible target,' the website added.
The website explained that 'laser-directed energy weapons can engage targets at the speed of light, and use an intense beam of light to cut through the target.'
