The ShadowHawk is a 50lb mini drone chopper that can be fitted with an XREP taser with the ability to fire four barbed electrodes that can be shot to a distance of 100 feet, delivering “neuromuscular incapacitation” to the victim. The drone can travel at a top speed of 70MPH and can operate for 3.5 hours over land and sea.

A video clip of the drone shows off its impressive maneuverability as it tails a suspect attempting to evade capture with sophisticated object tracking technology. Another video shows the drone conducting surveillance of two individuals involved in a firearm transaction.

The drone also has the capacity to carry 37mm or 40mm grenade launchers and or a multiple shot 12 gauge shotgun.
