{"slug":"iron-dome-vs-s-400","question":"Iron Dome vs S-400","answer":"Iron Dome is Israel's short-range rocket defense system with a 90%+ interception rate against rockets and mortars. The S-400 Triumf is Russia's long-range air defense system designed to shoot down aircraft, cruise missiles, and ballistic missiles at 400km range. They serve completely different roles.","answer_curated":true,"verdict":"These aren't competitors — they're different classes. Iron Dome defends against short-range rockets (Hamas, Hezbollah).

Russia claims yes. Western analysts are skeptical, as the F-35's stealth and electronic warfare capabilities are designed specifically to defeat systems like the S-400.
