Yes, militaries are working on drone swarms

That the battlefield of tomorrow will be abuzz with death is clear. Say hi to America's drone cannons.

LOCUST can launch swarming UAVs to autonomously overwhelm an adversary. The deployment of UAV swarms will provide Sailors and Marines a decisive tactical advantage.

"The recent demonstrations are an important step on the way to the 2016 ship-based demonstration of 30 rapidly launched autonomous, swarming UAVs," said ONR program manager Lee Mastroianni.

The LOCUST program includes a tube-based launcher that can send UAVs into the air in rapid succession. The breakthrough technology then utilizes information-sharing between the UAVs, enabling autonomous collaborative behavior in either defensive or offensive missions.

Since the launcher and the UAVs themselves have a small footprint, the technology enables swarms of compact UAVs to take off from ships, tactical vehicles, aircraft or other unmanned platforms.
