[i]The F-15SA is the second version (after Singapore) to be delivered with the APG-63(V)3 active, electronically scanned array (AESA) radar. It is the first to have BAE Systems’ digital electronic warfare system (DEWS), .....Like the Singaporean aircraft, it has a Lockheed Martin AAS-42 infrared search-and-track system, known as TigerEye on the F-15.
The Saudi variant is the first all-fly-by-wire F-15, which is expected to reduce maintenance requirements because the controls are self-rigging. It has a so-called PDM-free wing that does not require periodic depot maintenance on its structure. Another change is that the wing stores stations Nos. 1 and 9 are activated, mainly in order to carry a larger air-to-air load in conjunction with air-to-surface weapons. The Saudi order includes AGM-88B High-Speed Antiradiation Missiles from U.S. stocks.[i]
Are these F-15s better than any in the US inventory? Certainly they are the 1st all fly by wire ones. Though I am not sure that helps in combat.
