Absolutely incorrect. The F-15SA is an excellent CAS platform with good loiter capability and a large munition carrying capacity. The A-10s claim to fame is its gun and payload. The F-15 is able to replicate the payload easily , and for anything other than tanks.. the 20mm vulcan is quite effective.It is a deep strike platform not a ground support platform, the SU-24 and he A-10 thunderbolt are dedicated ground support platforms.. most fighters can do ground strike and naval strike and air to air combat , but we are talking about a ground troops support platform, if the JF-17 is used in that role it will free the other more potent and powerful platforms to perform other important missions..
KSA is getting its F-15SA in 2017 through 2020 and will upgrade all its F-15 S to SA locally..
