Israeli financial daily Calcalist reported that Iran has possessed American stealth drone technology since 2011 and has since produced at least five radar-evading unmanned aerial vehicles.

The newspaper said Iran reverse-engineered the US RQ-170 Sentinel drone that crash-landed inside its territory in 2011, developing several variants under the Shahed series, including reconnaissance and attack models.

Calcalist warned that while Iran has used stealth drones in past operations, it did not deploy them extensively during the recent 12-day conflict, suggesting Tehran may be preserving the advanced systems for future engagements or export purposes.
