Meet SideArm: a giant drone catcher from DARPA that can horizontally launch and retrieve unmanned aerial systems of up to 900 pounds. It was recently tested by Aurora Flight Science to capture 400-pound Lockheed Martin Fury UAS repeatedly.
SideArm fits in a 20-foot shipping container. It can be transported by truck, ship, rail, or helicopter. A crew from 2 to 4 is required to set up the system. The above video show a prototype of SideArm in action.
