China’s aviation industry has achieved a significant milestone in stealth technology with the unveiling of a sixth-generation stealth fighter jet capable of evading military-standard radar detection. Zhou Hai, from the AVIC Chengdu Aircraft Design and Research Institute, introduced a more rigorous testing framework for evaluating stealth materials, as published in Advances in Aeronautical Science and Engineering.
Stealth background materials—essentially, the materials that allow aircraft to remain undetectable by radar—must block electromagnetic (EM) waves emitted by advanced military radars while remaining thin and lightweight. Additionally, they must counter low-frequency anti-stealth radar systems. Even weak EM emissions, such as those from exhaust nozzles, must be accounted for to achieve comprehensive stealth capability.
A recently spotted aircraft resembling the one described in Zhou’s study was photographed flying over Chengdu, Sichuan Province. This Falcon-like tailless stealth jet features a distinctive aerodynamic design inspired by a ginkgo leaf, with pronounced chine lines extending to the nose and a wide, delta wing. Its tailless configuration, nose-mounted air intake, and three-engine system represent a significant leap in stealth aerodynamics.
Reports suggest the aircraft is designed for a variety of roles, including air combat, electronic warfare, and directing drone swarms. With potential applications in space and naval operations, the jet’s multifunctional platform highlights its versatility in modern warfare. This development has intensified discussions about the global race for sixth-generation fighter jets.
Meanwhile, the U.S.’s Next Generation Air Dominance (NGAD) program faces challenges with the effectiveness of stealth coatings across a range of radar frequencies and angles. In contrast, China’s advancements in radar-absorbing materials and aerodynamics position its stealth jet as a strong contender for next-generation air dominance, reflecting the nation’s growing influence in military aviation technology.
