Bavar-373 is Iran's road-mobile long-range surface-to-air missile system, developed by the Aerospace Industries Organization after the S-300 procurement gap and fielded in 2019. Iranian sources later advertised Sayyad-4B and Bavar-373-II upgrades with longer claimed reach, while 2025-2026 conflict reporting treated the system as part of Iran's high-end air-defense layer under Israeli and U.S. suppression pressure rather than a publicly confirmed source of intercept kills.
During Operation Rising Lion, specialist aviation reporting said Israeli strikes against Iranian air-defense facilities targeted SAM sites including Bavar-373, S-300, and 3rd Khordad systems; FPRI separately assessed that Israeli air superiority and suppression kept visible Iranian SAM activity limited, so the row supports Bavar-373 as a targeted/fielded air-defense layer rather than a confirmed interceptor success.
Role detailsDuring the 2026 Operation Epic Fury phase, Business Insider described Bavar-373 as part of Iran's higher-end layered SAM network while reporting U.S. military assessments that those long-range air defenses had been degraded enough to stop being major planning factors.
Open-source descriptions present Bavar-373 as a distributed road-mobile SAM battery rather than a single vehicle. The later upgrade path centers on longer-range Sayyad-family missiles and launch vehicles with more onboard sensor and fire-control functions.
| Element | Documented function | Source-backed notes |
|---|---|---|
| Transporter-erector-launchers | Missile launch vehicles | Army Recognition and CSIS describe truck-mounted launchers carrying Sayyad-family interceptors as the visible battery firing element. |
| Detection and engagement radars | Search, tracking, and fire-control support | CSIS reported Iranian claims for target detection, tracking, and engagement, while later Iranian reporting advertised higher claimed range figures for upgraded versions. |
| Bavar-373-II vehicles | More autonomous launcher configuration | Defense reporting on the 2025 configuration described launch vehicles integrating radar, fire-control, and launcher functions to reduce battery dependency on separate vehicles. |
Public reporting treats Bavar-373 as a family of road-mobile long-range SAM configurations built around Sayyad-family interceptors, with later Iranian claims centered on longer-range missiles and more autonomous launcher vehicles.
| Variant | Configuration | Designation notes |
|---|---|---|
| Sayyad-4B upgrade | 2022 missile and range upgrade | Iranian reporting credited the Sayyad-4B update with extending claimed detection and engagement ranges compared with the original public claims.

| Bavar-373-II | 2025 autonomous TELAR-style configuration | Defense reporting described Bavar-373-II as a later configuration with more autonomous launch vehicles integrating radar, fire-control, and launcher functions. |
CSIS notes that Iran first unveiled parts of the Bavar-373 system in 2016 after earlier S-300 delivery delays pushed Tehran toward a domestic long-range SAM program.
Iran displayed Bavar-373 and announced its entry into service with claims that the system could detect, track, and engage targets at long range.
Iranian reporting described an upgraded Bavar-373 with Sayyad-4B missiles and longer claimed detection and engagement figures.
Defense reporting described a Bavar-373-II configuration built around more autonomous launch vehicles and updated battery architecture.
FPRI's review of the June 2025 air and missile-defense fight identified Bavar-373 among Iran's promoted indigenous SAM systems while emphasizing limited visible Iranian SAM effectiveness under Israeli air superiority.
Business Insider reported U.S. military assessments that Iran's higher-end systems, including Bavar-373 within the layered SAM network, were no longer major planning factors during Operation Epic Fury.
