Although Russia’s defense program marketing efforts may be among the most robust in the world, China is no slouch when it comes to making lofty claims about military capabilities through state-owned media outlets with global reach. China’s latest claim pertains to a new radar system that, according to reports, might render stealth technology obsolete.

In February, Chinese state-owned media reported on a spray-on coating they claimed had turned their J-16 into a “near-stealth” fighter. Although a radar-absorbent coating does play an important role in any stealth aircraft’s ability to evade detection, simply spraying it onto a platform prone to producing both large radar and IR returns does little to offset detection. However, according to Chinese media, the coating not only gave the aircraft stealth “capabilities,” it also made it nearly invisible to the naked eye.

“Brigade commander Jiang Jiaji, the first pilot to win the PLA’s Golden Helmet competition three times, told CCTV at the exercise that the silver-gray painting covering the J-16 is a kind of cloaking coating that gives the warplane a certain stealth capability, making it nearly invisible to the naked eye and electromagnetic devices,” China’s state-owned Global Times reported.

Now China claims to have developed a new radar array that can penetrate the stealth coating found on most low-observability aircraft, delivering radar returns that are precise enough to make a clear distinction between the types of aircraft that have been spotted. The radar array works by using terahertz radiation, which travels in a frequency range that’s higher than radio or microwaves but lower than infrared light waves. Theoretically speaking, terahertz radiation could penetrate the composite materials and radar-absorbent coating of a stealth aircraft, then bounce off of the metallic objects housed inside and produce a viable radar return.
