Family stepArab News and GIDS describe Shahpar-III as the third generation of the Shahpar series, following Shahpar-II and adding greater payload and endurance margins for armed missions.
Official current scanGIDS's current page lists the 140 hp Shahpar-III with SATCOM, six hardpoints, 570 kg external payload, EO/IR, SAR, COMINT/ELINT payload options, and AI-assisted video processing.
