Russia's drone delivery window closed on 31 March with no public confirmation that Iran received upgraded Shahed-136 variants with AI guidance and jet propulsion. 1 The Kremlin continues to deny all transfers. EU High Representative Kaja Kallas confirmed at the G7 on 26 March that the phased deliveries were due for completion by end of March.
The absence of confirmation is not evidence of non-delivery. Iranian operational use of upgraded Shaheds, identifiable by their flight characteristics and targeting precision, would be the first clear indicator. The Prince Sultan Air Base strike on 27 March used 29 drones of unconfirmed origin .
