What is the difference between the FIM-9E and the FIM-9K

I was wondering what the difference is between these missiles. Also the MIM-72C and the -72E.

9E doesn’t have a proxy fuse, meaning it directly has to hit the aircraft. 9K has a proxy fuse, meaning it can damage an aircraft on a near miss. IRL there’s a couple differences that aren’t modelled in-game IIRC. 72C is rear-aspect only, while 72E is all-aspect. Both are shit.


Thank you

I fucked up actually. The 72C is all-aspect as well. Don’t know what the real difference is between them, I guess.
