SU-39 with R-27ER and Grippen JAS39-5

Why the SU-39 has access to SARH and to the R-27ER no less and remain at 11.3?

So it has a radar pod + R-73 + R-27ER = 11.3?

SU-39 = 12.0
SU-25T = 11.7
SU-25SM3 = 11.3 (This variant misses 2xR-60M on its payload and no IRCM module on its booty)

This changes only for Air Realistic Battles

Now why the JAS39-5 is 13.0, we finally got a decent decompression and now a new premium vehicle with FOX-3 is at 13.0…

JAS39-5 = 13.7 (How is it even lower in BR than the premium/tech tree Viggen (JAS37DI / F21 that have RB74 not RB-74(M)) that are at 13.3?)
JAS39D = 13.3 (JAS39-5 has the same radar and same engine of this variant, but this one lacks guns, it should be 13.3)

How many years do we will need to wait to those planes be moved to a higer BR?

11.7 if it has R-27s

Still too low (should be 12.0), but it’s not 11.3.

only if it is the R-27R not the ER
