Russia's air-defense network in the south now operates with visible gaps large enough for Ukrainian drones to penetrate from the Black Sea to Rostov — a 400+ km strike corridor that did not exist when the layered system was intact. The mainland relocation of Crimea-based fighters (Su-30SMs) to Vityazevo puts them within the same standoff range, meaning Russia has traded peninsula vulnerability for mainland vulnerability without gaining survivability. If this pattern holds, Russian air operations over the southern front face a choice: operate from northern bases beyond Ukrainian drone reach (reducing close-air support tempo) or accept attrition rates that will force aircraft rotations faster than pilot training can replace them.
Ukraine is systematically collapsing Russia's integrated air-defense architecture in the south, forcing combat aircraft off Crimea and into mainland bases where they remain vulnerable to 300+ km standoff strikes.
Each radar kill widens the corridor for Ukrainian long-range weapons — the pattern visible in weeks-old targeting of co-located fighters and S-400 batteries now repeating at scale. Watch whether Russia responds by pulling air-defense assets from other fronts (northern sectors, occupied territories) to reconstitute the southern net — that would signal defensive desperation and expose other lines.
How many radar sets remain operational in Russia's southern integrated air-defense system, and what is the actual attrition rate relative to replacement production? The 20-in-August figure is a data point, not a trajectory.
