Iran’s Sevom Khordad Air Defense System: Tech Breakdown

TEHRAN (June 2025) – Iran’s Sevom Khordad (Third Khordad) is a mobile, medium-to-long-range air-defense system that has proven its operational value—most notably shooting down a U.S. RQ-4 Global Hawk in 2019 . Here’s a clear, U.S.-style technical overview:

✈️ System Architecture & Mobility

Platform: Road-mobile TELARs (Transporter Erector Launcher with Radar) mounted on 6×6 IVECO chassis.
Battery Composition: Each battery includes 1 TELAR with radar and 2 missile-only TELs, totaling 9 ready-to-fire missiles. A full battalion has 4 batteries plus a Bashir S-band surveillance radar with 350 km range.
Mobility Specs: Diesel-powered, capable of 65 km/h on road and ~500 km operational range. Launch-ready in under 3 minutes.

🛡️ Radar & Targeting

Engagement Radar: X-band AESA radar on TELAR—a “Buk-style” modern phased-array system.
- Detection: Up to 100 targets simultaneously
- Engagement: Can engage 4 targets concurrently, guiding 2 missiles per target.
Battalion Radar: Bashir 3-D S-band radar for early detection and networked C2 connectivity.
Integration: Part of Iran’s multilayered air defense, connected via data link to other systems to resist jamming.

🚀 Missile Suite & Performance

Primary Missiles: Taer‑2B (range 50–105 km, altitude up to 30 km).
Upgrades: Testing suggests integration of Taer‑3 extends engagement to ~200 km.
Close Defense: Optional loadout of eight Dey‑9 short-range SAMs for drone and fighter interception.
Kinematic Envelope: Effective against aerodynamic threats at 2–105 km and cruise missiles at 2–15 km altitude; target speeds up to 800 m/s.

🔬 Why It Matters

Proven Combat Value: Successfully shot down a high-value RQ-4 drone in 2019—first operational intercept of its kind.
Balanced Design: Mobile, radar-integrated, versatile missile mix gives the system adaptability across scales of threats.
Networked Resiliency: With AESA + S-band radars and data-link, provides multi-tiered coordination and enhanced jam resistance. However, effectiveness still lags behind Western systems like S‑300, S‑400, and Patriot—especially in radar sensitivity and stealth detection.

Iran Warns U.S. to Brace for “Everlasting Consequences” After Airstrikes

Washington, D.C. — Iran has issued a stern warning following U.S. airstrikes on its key nuclear facilities, accusing Washington of reckless aggression and urging Americans to prepare for severe reprisals. Spokesman for the Khatam al-Anbiya Central Command, Ebrahim Zolfaqari, delivered a statement today. Photo: Dnevnik During a televised statement, Iranian Foreign Minister Abbas Araghchi condemned the operation as a “criminal act under international law,” while threatening “everlasting consequences” for the U.S. Meanwhile, Supreme Leader Ayatollah Khamenei declared that any direct military involvement by the U.S. could spark an “all‑out war” across the Middle East. The U.S., which authorized strikes using B‑2 bombers and Tomahawk missiles targeting Fordow, Natanz, and Isfahan, describes the action as a decisive blow aimed at halting Iran’s nuclear progress—and insists it does not seek regime change. President Trump called the operation a “spectacular military success” and warned that ...

U.S. B‑2 Bombers Strike Three Iranian Nuclear Facilities, Trump Announce

WASHINGTON D.C. (June 22, 2025) — President Donald Trump has confirmed that U.S. B‑2 stealth bombers successfully carried out airstrikes on three Iranian nuclear sites—including the heavily fortified Fordow facility—aiming to pressure Tehran back to the negotiating table. Iranian officials acknowledged that the Fordow complex was hit, along with installations near Natanz and Isfahan. State media reported that no radioactive material was present at the time of the strike and that personnel had been evacuated in advance . Trump: Diplomatic Motive Behind Military Action According to U.S. sources cited by CNN, President Trump authorized the operation hoping that striking hardened nuclear assets would compel Iran to return to negotiations. Officials emphasized that no further U.S. strikes inside Iran’s territory are planned—at least for now . Political Fallout in Washington Reactions in Congress were sharply divided: Republican Rep. Thomas Massie condemned the strike as unconstitution...
