IDF Phantoms received Elbit Jason digital bombing computers, Litton LW-33 inertial navigation systems, new radar warning receivers, TISEO and combat slats. IDF Phantoms took part in many other battles, among them Operation Mole Cricket 19 in June 1982, when Syrian SA-6 sites were destroyed by a coordinated attack made by IDF aircraft and unmanned aerial vehicles. By that time, new F-15 Eagles and F-16s were replacing the Phantom in front line service, so the F-4s scored only one aerial victory in that action. Weapons Among the weapons carried on IDF F-4s were the Gabriel, AGM-45, AGM-68, Shafir and Python missiles. Upgrades The planned program to replace the original J79 engines with the Pratt & Whitney PW1120 was cancelled, but the fleet was updated to Kurnass 2000 standards. This upgrade included installation of a wide-angle Kaiser HUD, a digital mission computer and some structural improvements. The main updates involved the APG-76 radar, Elbit ACE-3 mission computer, HOTAS, the addition of winglets for increased agility, ASX-1 TISEO and the ability to deploy Popeye missiles. The upgraded aircraft first flew on 15 July 1987 and was formally accepted on 11 August 1987. The Kurnass program was also used to upgrade Turkish Air Force Phantoms at the same time, realizing some economies of scale. Israeli Phantoms have suffered at least 55 combat losses but accounted for 116.5 claimed air victories. By the end of the 20th Century there were still 112 F-4s serving with the IDF, in three Squadrons: the 119, 142 and 201.

On 1 November 1968, this choice was made public and Japan became one of the few countries that license-produced this aircraft. The Nihon Koku Jietai (Japan Air Self-Defense Force, JASDF) received a total of 154 F-4EJ and RF-4Es. While the F-4EJs were built almost entirely by Mitsubishi Heavy Industries, the RF-4Es were bought directly from McDonnell-Douglas. Due to Japanese military limitations prohibiting air-to-ground ordnance, the F-4EJs were delivered without the AN/AJB-7 bombing computer system and also did not have an air-refueling probe or receptacle.
