During the United States-Iran Conflict, defense reporting described Bavar-373 as part of Iran's layered long-range surface-to-air missile network as U.S. and Israeli strikes targeted Iranian air defenses; separate April 2026 reporting said Iran used a new, unspecified air-defense system to target a U.S. fighter jet.
