On F-4E/G models, the digital ARN-101 navigation system replaced the LN-12 inertial navigation system. The F-4E was equipped with the APQ-120 which offered considerable improvements in weight (290 kg), volume, performance and reliability through the use of solid-state circuitry.
So it actually despite being smaller and lighter actually did have superior range and tracking ability?
The F-4E also was equipped with the AIM-7F missile. The Northrop "Target Identification System Electro-Optical (TISEO)" camera system was also introduced in late F-4E production, being retrofitted to older aircraft as well. TISEO involved a steerable, stabilized telescopic camera mounted on the left wing, and was used primarily to inspect targets before engaging them. TISEO imagery was displayed on the WSO's radarscope. The camera could be slaved to the AN/APQ-120 radar, and linked to the navigation system to target flight checkpoints as well.
So it effectively allowed one to identify enemy aircraft further out making for more BVR engagements?
Navy F-4J/S were equipped with The AWG-10 and AWG10B using the AN/APG-59 radar.
The AWG-10 was the fire-control system and the AN/APG-59 was the radar?
This was the first multi-mode radar set that included pulse-Doppler look-down capability as well as a comprehensive built-in-test (BIT) system.
Assuming it's not classified: When you say multi-mode radar, do you mean it possessed both air-to-air and air-to-ground capability?
I assume it performed better than either the F-4C's radar, or the AN/APQ-120?
As for the BIT capability, it could do auto-diagnostics on itself then?
Both aircraft had an auto-retract flap system. On the F-15C flaps automatically retracted at 250 kts. On the F-4D the flaps automatically retracted at 220 kts. +/- 10 kts. Some of us actually used this feature on the F-4 during air-to-air as using ½ flaps provided some additional slow speed capability.
