The F-15QA (Qatar Advanced) is the most advanced variant of the F-15 Eagle. It is based on the F-15SA that is in production for Saudi Arabia, and has the same fly-by-wire flight control system introduced by the Saudi version. It also has Raytheon’s APG-63(V)3 AESA radar, Lockheed Martin AAS-42 Tiger Eyes infrared search and track system, a redesigned internal wing structure, and two additional wing hardpoints that allow it to carry up to 16 AIM-120 AMRAAM air-to-air missiles.
Where the F-15QA differs is that it is the first version to feature a new BAE Systems head-up display and a single wide-area cockpit display that replaces the multiple screens of previous variants. Boeing has also installed a new mission computer and a digital electronic warfare suite. The F-15EX for the U.S. Air Force is based closely on the Advanced Eagle that Saudi Arabia (F-15SA) and Qatar (F-15QA) both procured.
