With so much additions coming concerning ground radars, like the new mi-8 aesa radar, the F-15E, SU-24M’s radar rework, Gaijin could look onto making the ground targeting capabilities fo the Su-39 radar pod more useful.
Here some proof of the situation:
If you manage to have a hard lock, it still loses track easily
I don’t know how it performed in irl, but this thing as it is in the game is useless. It can guide the vikhir missiles, and even use datalink to guide two of them. Being able to hit targets behind smoke or in poor weather, but not being able to keep a stable lock – even a hard lock slips – just makes it not worth, not even for just searching targets, in case of bad visibility.
