I wasn't the first to spot these - a colleague of mine identified them in satellite imagery, after which we held some discussions about the findings.Is this your own finding
First, this cluster spans approximately 40 kilometers north-south, containing around 90 uniformly distributed similar structures (the exact count requires verification). If these are indeed silos, their configuration resembles the mountain-shadow concentrated deployment scheme used for the MX missile system.what makes you think they're ICBM silos?
Second, while I'm familiar with the training silos at Jilantai, these differ completely in both scale and design. I assess these to likely be slide-opening silos - the white-black-white patterns likely represent sliding tracks. All previously observed silos used flip-top mechanisms, though I recall a now-removed painting at the National Museum depicting slide-opening silos.
While I cannot state this with certainty, the scale of this complex suggests this interpretation is plausible. Additional analysis and discussion would be valuable.
