Thk terminator i think its more close to EJ correct me if im wrong
I think 2020 would most likely be closest to Kurnass 2000.
Whereas AUP is more of a multirole upgrade similar to German ICE, Terminator was more oriented around a strike aircraft, and it’s air-air capabilities remained similar to original F-4Es, with benefit of a better radar.
Upgrade was done by Israeli IAI, radar and many other components are of Israeli origin. As far as I remember it has two MFDs for back and one for front cockpit, as well as something akin to ICP & DED for both. I think it also had a new RWR. AGM-142 Popeye was probably the “shiniest” new addition to it’s arsenal.
Curiously though, no new TGP was integrated, and TGP capabilities remained same as the old F-4E, Pave Spike if I recall correctly.
I had an old magazine from ye olde 90s that had (fairly small) diagrams of cockpit upgrades.
Not sure if any additional upgrades were introduced since then, I think new Turkish cruise missile SOM was supposed to be integrated on it, and was test fired from one. Maybe locally designed/produced Aselpod TGP was also integrated not sure.
