The norm for the F15 is the center line tank only, however, there are times when the two wing pylon tanks would be installed without the center line, it depends on mision requirements. I do not know of any time that bombs have been carried by an F15A ,B,C or D. I think I remember hearing something about IDF Eagles being fitted to carry bombs, but I'm not that sure of it. I know they are getting an E varrient now.
