The US military is developing a futuristic weapon to shoot enemy drones out of the sky at the speed of light.
Named THOR, the weapons system uses a drone-killing microwave beam to stop swarms of drones, which have proven incredibly difficult to defend against.
The US military this month released a visualisation showing how THOR can protect bases and outposts from small drones carrying explosives.

In the video, THOR's microwave beam sweeps across the sky at the speed of light, taking out enemy drones.
THOR is viewed inside the US military as an ideal way to stop drones which are carrying explosives or surveilling troops and operations below.
Islamic State fighters began to use low-cost drones, like those used by everyday hobbyists, with increasing frequency to attack coalition forces in Iraq and Syria.
The fast-moving drones can be notoriously hard to counter.

Prototypes of THOR, also known as a Tactical High Power Microwave Operational Responder, were tested in Africa last December.
"It's been tested extensively, works remarkably well," US Air Force chief scientist Richard Joseph told the Mitchell Institute.
"I've watched it in action and it's really quite impressive."
The US military is planning for THOR to be stationed at bases around the world.
THOR uses short bursts of high-powered microwaves to fry the electronics of incoming drones.
The weapons system can be easily packed inside a shipping container and rapidly moved to bases around the world.
THOR can be set up and operational in three hours, according to the US military.
