Iran’s stealthy “358” loitering interceptor—also known as Saqr-358—is emerging as a disruptive, low-cost counter to high-value U.S. ISR assets like the MQ-9 Reaper. What makes the 358 especially dangerous is its cost asymmetry—tens of thousands of dollars versus multi-million-dollar platforms—turning it into a high-impact, low-cost threat. Interest from China further underscores its potential role in future conflicts, particularly as drone warfare becomes central to modern battlefields.
