Israel reportedly has US-made drones capable of launching grenades

Aerodynamics and physics dictate that you can't quite strap an assault rifle onto a DJI Phantom and expect it to fly and hit a target. Florida company Duke Robotics has apparently devised a way to keep a drone steady while compensating for a gun's recoil. "Though a system of flexibly connected pates, the TIKAD distributes the backward momentum in a way that keeps the vehicle stationary in the air," Defense One writes. "A ten-pound robot gimbal allows six degrees of movement freedom and the ability to rapidly re-target the weapon and camera." Supposedly the system can keep a UAV steady whether it has a grenade launcher for a payload, or a pistol -- so long as the weapon is under 22 pounds.
