Ukrainian military intelligence claims that the air‑defense system around Moscow contains more than 100 S‑300 and S‑400 launchers and about 50 Pantsir systems, giving the city a stockpile of over 700 ready‑to‑fire missiles.
The agency also says at least one S‑500 "Prometheus" system has been deployed in the Moscow area, although independent confirmation is lacking. Video footage circulating on social media shows Russian helicopters transporting and installing Pantsir units on rooftops in the capital, a move aimed at strengthening close‑range air defense against drone attacks.
