People’s Daily republished an article from the PLA Daily highlighting the role of infrared-guided missiles in reportedly damaging a U.S. F-35 stealth fighter during the Iran conflict.
According to the article, the aircraft was struck by a surface-to-air missile over central Iran and forced to make an emergency landing, although the details remain unconfirmed. Analysts suggest that Iran’s short-range air defense systems or portable infrared-guided missiles may have been responsible. The incident underscores the effectiveness of infrared missiles as close-range weapons capable of targeting advanced stealth aircraft.
The article explains that infrared missiles rely on passive detection, meaning they do not emit signals and are therefore difficult to detect or jam. Because all objects above absolute zero (-273.15°C) emit heat, even stealth aircraft—designed to evade radar—remain vulnerable due to their thermal signatures. These missiles can track heat sources and enable “silent” engagements, making them effective in short-range ambush scenarios across land, sea, and air platforms.
Although infrared missiles have limitations—such as shorter range, sensitivity to weather and lighting conditions, and susceptibility to decoys—they remain widely used due to their relatively low cost, operational simplicity, and adaptability.
