Britain shows off a laser weapon that could take out drones for as little as $13

• The UK has showcased its new laser weapon, DragonFire. 
• The weapon is highly accurate and cheap, the Ministry of Defence said, costing just $13 a shot.
• Lasers could prove an effective new form of air defense against military drones.

The UK's Ministry of Defence has released new footage of its laser weapon DragonFire being tested.

The video showed the laser-directed energy weapon, or LDEW, system successfully shooting an aerial target in tests off the coast of Scotland in January.

The weapon "has proven itself in testing and has the very real potential for it to transform the UK's Defence capability," the MOD said in a statement.
