Comrades Wong and Chen, keep up the excellent People’s work you are doing.
Here what Grok 4, that piratical capitalist tool, has to say regarding the glorious PLA’s triumph in easily evading the best radar detection the degenerate Americans and their South Korean and Japanese lackey lapdogs have to offer:
Yes, there is some basis to the recent online buzz about a Chinese stealth fighter jet—specifically the J-20 “Mighty Dragon”—evading U.S. and allied detection systems, but the claims appear to stem primarily from Chinese state media and lack independent verification from Western or neutral sources, suggesting they may be exaggerated for propaganda purposes. These reports surfaced in late July and early August 2025, aligning with heightened U.S.-China tensions in the Indo-Pacific, including increased PLA Air Force (PLAAF) patrols near Taiwan and Guam. I’ll break this down based on available information, noting that while stealth technology inherently challenges radar systems, absolute “undetectability” is rare and context-dependent (e.g., radar type, distance, environmental factors).
The Specific Claims Circulating Online
The core narrative revolves around a July 27, 2025, PLAAF mission where a J-20 reportedly transited the Tsushima Strait (between Japan and South Korea) and the Bashi Channel (south of Taiwan), areas heavily monitored by U.S., Japanese, and South Korean radars, including advanced systems like THAAD (Terminal High Altitude Area Defense) and Patriot missiles. Chinese state broadcaster CCTV aired footage implying the flight went unreported by regional militaries, framing it as a demonstration of the J-20’s low-observability (stealth) capabilities. Social media amplified this with videos and posts claiming the jet “evaded” U.S. boundaries near Guam, sometimes tying it to broader PLAAF incursions. Some accounts exaggerated it as a “shock to the West,” portraying the J-20 as untouchable.
Evidence and Substantiation
• Chinese Perspective: Beijing’s reports position this as proof of the J-20’s effectiveness, with upgrades like improved radar-absorbing materials, a redesigned canopy for better stealth, and domestic WS-10C engines reducing infrared signatures. A June 2025 upgrade reportedly tripled its radar detection range using advanced semiconductors, enhancing its ability to operate undetected while spotting adversaries first. Analysts note the J-20’s design (canards, diverterless supersonic inlets) minimizes radar cross-section (RCS), potentially comparable to U.S. F-22/F-35 in certain bands, though not fully “invisible.” China has also tested sixth-generation concepts with even lower RCS, like the tailless J-36 and J-50, which could build on this.
• U.S. and Allied Silence: No official responses from the U.S. Department of Defense, Japan, or South Korea confirm or deny the undetected flight. This could indicate it didn’t happen as claimed, or that allies chose not to publicize detections to avoid escalating tensions or revealing capabilities. Past incidents, like Indian claims of detecting J-20s with Su-30MKI radars in 2018, suggest stealth isn’t foolproof, especially against low-frequency or multi-angle radars. U.S. systems like E-2D Hawkeye or ground-based radars are designed to counter stealth, but gaps exist in vast oceanic areas.
• Broader Context and Limitations: Stealth evades high-frequency radars well but struggles against low-frequency (VHF/UHF) systems like China’s JY-27A, which claims to detect F-35s at 200+ km. The J-20 has been “detected” in exercises (e.g., “shot down” by a J-10C in simulations), and experts like Justin Bronk argue its stealth is partial, especially with radar reflectors used in peacetime. Related claims, like Chinese carriers approaching Guam undetected, highlight electronic warfare (e.g., electromagnetic fog from Type 815A ships), but these are also unverified. Overall, while the J-20’s stealth is advanced and could delay detection, complete evasion in a contested area like Tsushima is improbable without countermeasures like jamming—claims of which appear in X posts but lack proof.
In essence, there’s partial truth in the sense that China’s stealth tech is rapidly advancing and challenging U.S. dominance, but the specific “undetected flight” narrative seems like state-driven hype rather than substantiated fact. Independent analyses (e.g., from Asia Times, The War Zone) view it as a psychological flex amid sixth-gen races, not a game-changer |
