Bulgaria joins NATO PURL for joint Ukrainian UAV production

Bottom line

Bulgaria has joined NATO's PURL mechanism and signed a 10-year security agreement with Ukraine, including a joint weapons production deal for UAVs under the 'Drone Deal' initiative.

Why it matters

This expands the NATO industrial base for Ukrainian drone production, potentially increasing the volume and variety of drones available to Kyiv and integrating Bulgarian manufacturing into the broader NATO supply chain for the conflict.

Rybar reports that Bulgaria has shifted from covert supplies to a commercial model for arms exports to Kyiv by joining NATO’s PURL mechanism. A 10-year security agreement includes a joint weapons production agreement for UAVs under the ‘Drone Deal’ initiative. This marks a significant escalation in Bulgaria’s direct industrial support for Ukraine’s drone ecosystem.
