I would echo this. With just the A-A capability, I think the APG-71 could be accurately simulated. Don't know about the IRST given a lack of details on it. I just know I've heard there were plans of improving it if they had gone ahead with upgrading to the proposed Super Tomcat 21.
I'd also be curious if the improved AIM-54C++ could be simulated aswell if we ever get the D.
