in all likelihood everyone’s had this technology for a while now. i lean a bit towards giving the f35 the benefit of the doubt though, and just assume that its signature is small and fuzzy enough for it to have a smaller confidence interval than other less stealthy aircraft

same goes for submersible gliders equipped with passive sonar systems, just saturate an area with those and suddenly the ashbm kill chain is a lot more cloud cover resistant than nafo would have you believe
