The Joint Strike Fighter (JSF) program conducted two virtual air-to-air combat effectiveness Aircrew System Advisory Panels (ASAPs) at WPAFB in support of the Joint Operational Requirements Document (JORD). In December 1998 the program sponsored a collateral-SECRET level simulation to evaluate possible avionics configurations. Trade studies were conducted on proposed radar, infrared, and other weapons system attributes to determine their impact on JSF combat effectiveness in the Defensive Counter Air mission. Pilots from the JSF Operational Advisory Group (OAG), tasked to write the JORD, participated in the event.
