The taxpayer funded platform is four times as much.
Another potentially useful anti-drone device would be an old-fashioned, early 20th century spark-gap transmitter/antenna...the drones are probably designed to hover and circle if they lose contact with the controller. So, they eventually run out of gas/electricity, and drop out of the sky. It is important to recover it reasonably intact, because there are valuable goodies on/in it...for example, the particular drone in this article probably had a GoPro camera, which is very nice (a few hundred bucks at least) and could be “re-purposed”.
That's because its armament are $600 hammers!
