In stark contrast to chronic software crashes early on, the command-and-control system accurately tracked everything from drones to helicopters to fighter jets, both Army aircraft and Marine ones. (It’s hit ballistic and cruise missiles in earlier tests). It drew data from Patriot and Sentinel radars that were not designed to work together.
