The Iranian F-14A-GR in his main life fight as stock F-14A.
All main air battles, all victories and falls against the Iraqi airforce were flying as the stock versions. Was not upgraded.
So no need to create any later "degradation" of Iranian Tomcat when it has dead AWG9 radars, dead batteries for phoenixes = no use Aim-54, any cannibalized parts, and imported Russian avionics.
The great Iranian Tomcat from the 80s was clear US Tomcat with few exceptions determined for export. A bit downgraded ECM, ECCM (on Aim-54A) - a bit lower frequency of microprocessor, missing fuel probe (later was again introduced), had better engines: TF30-P-414A, IFF had component only for IFF Russian made aircrafts, not US. And Iranian "asia minor" skin. That's all. :)
