Clearly the Iranians are going to have to make a warranty claim for the failure of their recent purchase of the Chinese HQ-9B system.
There is no report that it worked with any effect.
If deployed and integrated successfully, the system would directly address one of Iran’s most serious vulnerabilities: its difficulty tracking and engaging modern Western fighters such as the U.S. F-35 and F-22.
Why the HQ-9B Matters
The HQ-9B is China’s most capable operational long-range surface-to-air missile system, often compared to Russia’s S-400. With a reported engagement range of up to 250 kilometers and the ability to intercept targets at altitudes approaching 50 kilometers, the system is designed to counter aircraft, cruise missiles, and some ballistic threats.
Unlike earlier generations of Iranian air defenses, the HQ-9B employs active radar homing in the missile’s terminal phase. This allows launch radars to disengage or shift targets after firing, complicating suppression efforts by attacking aircraft. Sources familiar with the reported delivery say the package also includes advanced phased-array surveillance radars, most notably the JY-26 “Skywatch”, which Chinese engineers advertise as optimized for detecting low-observable (stealth) aircraft.
