Since the new update completely destroyed j35xs the j35xs in real life can hold radar missles and they are not in the game it could hold the rb27
Also Finnish air force used R-13M1’s
It’s already been stated by Gaijin they consider them to bad to be added.
Which are equivalent to the missiles it already gets.
R-13M1s are far superior to the AIM-9J, they get 50% increased thrust
Gaijin haven’t added any aim4’s or any planes that only carry aim4’s. I don’t think they like them.
Old forum thread with additional info on AIM-4 performance.
Apparently the later versions were fairly decent missiles, despite the limitations of no proximity fuse. This’d also open the door for AAM-2 from Japan, which could be comparable to R-60M if sources are accurate. I have heard talk of swede upgrades to the AIM-4, but not seen any proper sources describing what was modified.
Turns out the AIM-4 was decent, as long as you flew anything but the F-4. Only the F-4 is to blame for the poor reputation of the missile. It basically had none of the fire control equipment to employ the weapon in a usable capacity.
R-13M1 also cannot lead as well as 9J nor turn as well due to that speed.
So while R-13M1 will go faster in a straight line, 9J will turn more with a better off-boresight capability as well.
