Iranian media agency Tasnim reported that the Islamic Revolutionary Guard Corps (IRGC) has downed a US F-35 Lightning II fighter jet, claiming to have captured a US pilot. This incident follows an earlier emergency landing of another F-35 due to Iranian fire. Analysts are questioning whether this marks the end of the era of stealth dominance in military aviation. The IRGC has not disclosed the specific air defense system used but is believed to have deployed an evolved version of the Bavar-373 or Khordad-15, utilizing advanced Passive Coherent Location (PCL) and Infrared Search and Track (IRST) technologies. These systems allow for tracking stealth aircraft by monitoring heat emissions rather than relying on traditional radar, which can be detected by stealth technology. The implications of this incident could be significant, as it may force the US to reconsider its military tactics in contested airspace. If confirmed, the capture of a pilot would also provide Iran with leverage in ongoing peace negotiations.
