They could bring back R13 to mig 21s back and add flares
Don’t add flares, but adding basic R-60 is basically necessary unless you’re a god with the water gun.
Leave the R-13M1 for the SPS-K, the difference is one has the engine, the other has the flares and the long arm (R-13M1).
What 21S needs is a missile that can kill something in a short span of time. So it can like, play the game below 5 km.
i agree
