Khorramshahr 4
The Khorramshahr 4 is an advanced Iranian liquid-fueled ballistic missile with a range of approximately 2,000 km, designed to carry heavy warheads and penetrate air defense systems.
The Khorramshahr 4, also known as the 'Kheibar,' represents a significant evolution in the Islamic Republic's strategic missile arsenal. As a fourth-generation member of the Khorramshahr family, it is characterized by its liquid-fuel propulsion and its ability to remain fueled for extended periods, reducing the preparation time required for launch—a critical factor in surviving pre-emptive strikes. With a reported range of 2,000 kilometers and the capacity to carry a 1,500 kg warhead, the missile is specifically engineered to reach targets across the Middle East, including the entirety of Israel.
Technologically, the Khorramshahr 4 is noted for its mid-course guidance system, which allows for trajectory adjustments outside the atmosphere, making it more difficult for traditional interceptors to track and neutralize. The Iranian defense establishment has emphasized its 'cyber-attack resistance' and high maneuverability during the terminal phase.
In recent operational contexts, the Yazd missile base has emerged as a primary hub for this platform. Intelligence reports from July 2026 indicate that the Iranian regime has been conducting 'layering work' at the entrances of missile tunnels at the Yazd facility. This activity is interpreted by security analysts as a high-readiness signal, preparing the infrastructure for rapid-response launches. The Khorramshahr 4 remains a cornerstone of Iran's deterrence strategy and its capacity for long-range precision strikes against regional adversaries.
