Worth noting that Yugoimport-SDPR (Serbia) revealed the Aleksandar SPH a few weeks ago, a fairly upgraded variant of the NORA B-52 they had sent for trials in Pakistan. Any chance the feedback from the trials could have gone into the Aleksandar?
I do not yet have the full technical details of the said trials. But I know for sure that none of the participating contestants were shortlisted or approved for further evaluation.
