- china stealth tech sure has come a long way - undetected flight of china's j-20 vs the supremely fortified Tsushima Strait between korea and japan - about 6 months ago and till now, not a word from the US, japan or sk; no denial or admission, recently another such undetected event happened near southern tw - the US-west have fallen behind and seem to have no answer at all to china's super fast military developments - btw the chinese govt and medias' reporting are a lot more trustworthy than western ones ...
- China’s J-20 stealth fighter reportedly conducted a patrol over the Tsushima Strait — a highly sensitive corridor between South Korea and Japan — without being detected by either nation’s radar systems.
The claim stems from a recent segment aired by state broadcaster CCTV, highlighting the missions of the First Fighter Brigade from the People’s Liberation Army Air Force (PLAAF).
While the program did not explicitly name the aircraft, it featured continuous footage of the J-20 and referenced patrols over the Bashi Channel and Tsushima Strait — strongly implying the jet’s involvement.
The Tsushima Strait is considered one of the most heavily surveilled airspaces in the region, monitored by advanced radar systems operated by Japan, South Korea, and the U.S. military, including the THAAD system. Neither Tokyo nor Seoul has acknowledged any recent incursion by a foreign stealth aircraft.
If validated, the flight would mark a significant milestone for the PLAAF, showcasing both the operational reach and the low-observability performance of the J-20 — and highlighting challenges for regional air defense systems in detecting next-generation threats.
