https://cast.pudmed.ir/videos/watch/c15d888b-267c-4b5b-bfd4-1a26d6243f2c The Soviet Union built a wall in the sky. It was called PVO – Protivovozdushnaya Oborona – Air Defence Forces. Separate from the Air Force, the PVO had one mission: no enemy bomber would ever reach Moscow. This episode covers the dedicated interceptors – the Su-15, MiG-25, MiG-31 – and the surface‑to‑air missile systems that made the Soviet sky the most defended on earth. In this full-length episode: 🔴 The Su-15 Flagon – The Interceptor That Shot Down Korean Air Lines 007 – The controversial 1983 incident. We examine the Su-15's design: delta wings, powerful radar, and no gun (only missiles). Why it was the PVO's frontline interceptor for 20 years. ⚡ MiG-25 Foxbat – The PVO's High‑Altitude Hammer – Designed to intercept the SR-71 and B-70. We cover its PVO service, its limitations, and its 1976 defection. 🚀 MiG-31 Foxhound – The Ultimate Interceptor – The successor to the MiG-25. Two seats, the first Soviet phased‑array radar (Zaslon), and the ability to fire six long‑range missiles at six targets. We break down its Mach 2.4 speed, its 1,500 km range, and its role as a flying command post. The MiG-31 remains the backbone of Russian air defence today. 🛡 The Missile Wall – S-75, S-125, S-200, S-300 – The surface‑to‑air missiles that protected Soviet cities and military sites. The S-75 downed Gary Powers' U-2. The S-125 sank an Israeli F-16? We explain the difference between interceptor aircraft and SAM systems. 🎖 The Pilots of the PVO – Life in the air defence forces: 24/7 alert duty, interceptions over the Barents Sea, and the psychological toll of sitting in a cockpit, engines running, waiting for World War III.
