A security incident involving the diversion of critical F-35 fighter jet components, including a cockpit canopy and weapons bay door, has prompted investigations by the Pentagon and the U.S. House Armed Services Committee. The parts, which were being shipped from Australia for inspection and repair, were reportedly diverted to Hong Kong and are believed to be held by Chinese authorities. These components feature radar-absorbent material that could assist in the analysis of stealth technology.

Following these developments, China has claimed the capability to detect stealth aircraft like the F-35 using various radar systems, such as passive, over-the-horizon, and meter-wave arrays. Technical assessments indicate that while low-frequency radars may detect stealth objects as metallic masses, they currently lack the angular precision required for effective targeting, leaving the full kill chain as a significant technical challenge.
