The Khorramshahr-4 just publicly displayed
The Khorramshahr-4, also known as the Kheibar missile, is an Iranian medium-range ballistic missile (MRBM) developed by the Shahid Hemmat Industrial Group. Unveiled in May 2023, it is the most advanced variant of the Khorramshahr family, featuring a liquid-fuel propulsion system and a heavy payload capacity.
Key specifications and capabilities include:
1. Range and Payload: It has an official operational range of 2,000 km (though analysts estimate potential capabilities up to 4,000 km) and can carry a warhead weighing approximately 1,500 kg, making it one of the heaviest payloads in Iran's arsenal.
2. Propulsion: The missile uses the Arvand engine with hypergolic propellants (UDMH and N2O4), allowing for a short launch preparation time of about 12–15 minutes compared to earlier liquid-fuel systems. While the missile's overall design is derived from the
North Korean Hwasong-10 (Musudan), the Arvand engine and its hypergolic fuel system represent a significant advancement in Iran's autonomous missile propulsion technology.
3. Guidance and Maneuverability: It employs an inertial navigation system with satellite updates and a Maneuverable Reentry Vehicle (MaRV) that can adjust its trajectory during the terminal phase to evade missile defenses.
4. Accuracy: The system is reported to have a Circular Error Probable (CEP) of approximately 30 meters.
5. Operational Use: In March 2026, during the 19th wave of Operation True Promise 4, the IRGC launched Khorramshahr-4 missiles at targets in Tel Aviv, including Ben Gurion Airport and the 27th Air Base, as well as at U.S. military installations in Qatar and Bahrain.
The missile is deployed on road-mobile transporter-erector-launcher (TEL) vehicles and is stored in hardened underground facilities within the IRGC’s "missile cities." Its design, derived from the North Korean Hwasong-10 (Musudan), emphasizes strategic deterrence and the ability to strike hardened infrastructure and air bases across the Middle East.
