Recent successes for Iran missiles and shooting down F15 and several other US warplanes leave US in a tenuous air military position.
Beidou is Chinese sophisticated GPS which we understand incorporates signal jumping to combat surveillance and communications capabilities not existing in GPS. I have no direct confirmation on ability to locate US aircraft yet.

Background

BeiDou publicly confirmed by Chinese embassy —; China is now openly acknowledging its role in Iranian military capability. The “Axis of Evasion” characterisation (Atlantic Council) is now structurally confirmed, not inferential

New today: First public Chinese government acknowledgement — this moves the thread from analyst inference to state-confirmed.
Why it matters: ⚑ This is the BeiDou elevation signal. The combination of public Chinese confirmation and sub-5m CEP reporting satisfies the threshold for elevating this frame. US and Israeli electronic warfare dominance over Iranian guidance is no longer structural.
