AN/APG-70 is an evolutionary branch of the
AN/APG-63 radar series, used on the late model
F-15C/D, Israeli F-15I and Saudi F-15S, as well as the
F-15E Strike Eagle.
[1] Late-model U.S. F-15's, however, now use an AN/APG-63 V(3), and the Strike Eagle will upgrade to the AN/APG-63 V(4), a hybrid developed from the active radar elements from the AN/APG-63 V(3) and the ground attack software of the AN/APG-70.
The AN/APQ-180 is an AN/APG-70 repackaged to go into an AC-130 aircraft.
