The inital 6 jets order for Zambia are L-15A with non-afterburning engine and no radar. It was reported that they made a follow up order for another 6 L-15A and 12 L-15B.The Zambian L-15Z is a subsonic, non-afterburning variant of the L-15 as confirmed with this interview with the Zambian Air Force. It does appear to have some sort of radar from photos posted here, but I do not believe anybody has been able to confirm which radar it is other than compatibility with PL-5EII all aspect WVRAAM as well any many guided air-to-surface munitions.
I cannot clear your doubt that L-15B with radar and afterburner are still at prototype stage of development. AAD 2016 is 5 years ago, many things have moved on.
