Those radars look to be the original fire control radars for the standard missiles (mihrab) of the navy. Seems that these radars were needed to adapt the mihrab to sayyad 2 level until the najm radars were available. I still see them in use for irgc exercises, indicating they are still used by them, but artesh has better najm radars for their sayyads. I always assumed talash was simply a testing phase for what would eventually become the 15th khordad and bavar systems, but it seems they might be operating in parallel and possible competition. The total system looks a bit bulky and seems to use an amalgam of older radars coupled with sayyad2 & 3 launchers and it seems to have different configurations of radars, ;aunchers, etc.
