Air War: What If Russia's Lethal Su-35 Battled America's F-15?
The Su-35S can carry over 17,000 pounds of munitions on its hardpoints, with up to 14 usable for air-to-ground attacks.
The F-15C can carry…none. Because it is purely an air superiority fighter. (To be fair, refitting for ground combat would not be an insurmountable task—Israel already refitted its Eagles in the 70s in this manner and used them destroy the Iraqi nuclear reactor at Osiriak.)
