> ranging from smaller equipment like semiconductors and GPS modules to larger parts like engines The Shahed-136 uses an MD-550 piston engine, according to Wikipedia. https://en.wikipedia.org/wiki/HESA_Shahed_136 https://en.wikipedia.org/wiki/HESA_Shahed_136 It was apparently developed by Limbach, Germany. Now the MD550 engines are made in China. https://www.militarydrones.org.cn/md-550-engine-price-p00583p1.html https://www.militarydrones.org.cn/md-550-engine-price-p00583... So the drones' engines don't appear to have anything to do with any US manufacturer, and even if they did, Iran could buy them from China. Good luck with sanctioning those.
