Counter Unmanned Aerial Systems (C-UAS)

When it comes to countering small unmanned aerial systems (C-UAS), we’ve combined three of our advanced technologies to address drone attacks. First, our Mobile – Acquisition, Cueing and Effector System (M-ACE) is an integrated system utilizing intelligent command and control tools to rapidly detect, track, and identify hostile targets and then cue the optimal effector. The M-ACE system can then “cue” a nearby Bushmaster® Chain Gun®, equipped with our advanced ammunition to provide an effective, low-cost kinetic defeat.
