AAM-4 Speed

Sorry if this has been posted already but anyone else notice that the AAM-4 only reaches Mach 2.7 then dumps its speed? shot 2 of them 6km behind another F15 and in the replay it showed mach 2.7 then dipped to 1.6 immediately and lost all tracking. Once again sorry if this was posted already or posted in the wrong section.


I thought it was too late. Thank you
