Bavar-373

Iran's flagship indigenous long-range SAM — an S-300/S-400-class system built to defend Tehran and its nuclear sites after sanctions delayed Russia's S-300. Iran claims it rivals the S-400; the 2025–26 air wars tested those claims hard.

Iran's flagship indigenous long-range surface-to-air missile system — an S-300/S-400-class air-defence platform built to shield Tehran, Isfahan and the nuclear sites after sanctions delayed Russia's S-300 deliveries. Iran claims it rivals the S-400; the Israeli and US air campaigns of 2025–26 put those claims under fire.

Overview

The Bavar-373 ("Belief-373") is Iran's most capable home-built long-range surface-to-air missile system, developed by the Ministry of Defence and Aerospace Industries Organization with Iran Electronics Industries. Built around the Sayyad-4 family of interceptors and a network of phased-array radars, it is a road-mobile system designed to engage aircraft, cruise missiles, drones and ballistic threats at long range — Tehran's sovereign answer to the Russian S-300 it struggled for years to obtain. Iranian officials describe it as the country's most significant air-defence achievement since the 1979 revolution and claim it matches or exceeds the S-300; independent verification is thin, and its real test came in the heavy air campaigns waged against Iran in 2025 and 2026.
