The Navy/Marine Corps has a new weapon in their inventory, and it may be just what the Coast Guard needs to deal with the potential threat of small, fast, highly maneuverable craft. It is a loitering munition, a drone with a warhead, making it a kind of slow cruise missile with an ability to abort.

Hero 120 will be going on the Marine Corps Long Range Unmanned Surface Vessel (LRUSV) as well as Marine manned ground vehicles.

Weight (with canister): 18 kg (40 pounds)
Warhead: 4.5 kg (10 pounds)
Range: 60+ km (32.4 nautical miles)
Endurance: 60 min
Engine: Electrical
Launch method: Single/Multi-Canister

Range is to some extent apparently limited by line of sight, but this could be used from land or from virtually any patrol boat.

Take a look.
