In addition to replacing the VISTA Simulation System (VSS) with a newer, upgraded version of the same system, a System for Autonomous Control of Simulation (SACS) will be added in order to operate X-62A as a Skyborg. One application is as autonomously piloted aircraft, perhaps as robotic wingman to a manned aircraft.
