The Russsians have not agreed to provide the workings of their radar to Israel to integrate the Derby-ER. Not sure they would want to, given how Israel humilates their equipment in the middle east. Note, that same radar that Su-30MKI is also on most of their top of the line fleet. They have no plans to given aways its secrets to anyone and i dont see them caring much for the Derby-ER either, as it gives them nothing and they lose military advantage through it !! This current setup is not the same as the Harrier integration with the Derby, etc.
The Russians may well have reviewed the encounter, and the loss of the Su-30MKI and determined it was the IAF at fault and not the platform, as we dont see Russia running around like headless chickens trying to integrate new missiles etc.. they seem rather calm, you have to wonder why !!!!!!!!
