Every Army Brigade Combat Team has an organic small drone capability for intelligence and situational awareness. These are smaller than the famous Predator and Reaper drones, and are currently unarmed.
But much as computers and cell phones have gotten smaller while greatly increasing their capabilities, defense contractors are seeing guidance kits and fuzing systems shrink while becoming ever more capable. And that means, there exists the possibility of deploying very small, yet extremely accurate, munitions from relatively small drones.
Raytheon is one company looking at fielding such a capability. Its Pyros small tactical munition could give small drones like the RQ-7B the ability to quickly strike time-critical high value targets. The small warhead also limits collateral damage.
The advanced warhead of Pyros uses an advanced semi-active laser seeker to precisely engage targets while significantly reducing the risk of collateral damage.
There are three choices for guiding the weapon to the target: GPS coordinates, inertial navigation or laser designation. To maximize kinetic effects and lethality, there are also three options for engaging the target: height-of-burst, point-of-impact or fuze-delay detonation.
Other companies such as General Dynamics are developing guided weapons based on 81mm mortar rounds.
