#Iran reportedly acquired fragments of the US AGM-158B JASSM-ER cruise missile near Arak. Remains include composite fuselage, wiring, and engine parts. Reports claim Iran obtained an intact missile and an unexploded WDU-42/B penetrator warhead. This allows Tehran to reverse-engineer stealth technology and improve air defense detection. Similar to the 2011 RQ-170 capture, this provides long-term strategic value for Iranian weapons development and countermeasures against advanced US munitions.
