Radar-linked computers convert data generated by onboard sensors to a readily comprehensible display for the pilot. Simultaneously, they relieve the pilot's workload by performing rapid ballistics, wind, velocity, altitude and other fire control calculations to ensure accurate weapons delivery to target. Release cues alert the pilot by means of HUD and CRT displays.

Today, the APG-65 radar has been superseded by the more capable APG-73. With no corresponding increase in weight, this radar is three times faster, has greater memory than its predecessor and provides for easier maintenance. It is characterized by a changed bandwidth, upgraded power supply, increased internal operating rates of the receiver/exciter, raised processing speed in the radar signal processor and new radar data processing hardware to boost throughput. Further upgrades will make high resolution radar ground maps comparable to those of the F-15E's APG-70 and the U-2.
