Iran fires ‘dancing’ ballistic missile with solid fuel and 1,240-mile range
Iran has confirmed the use of its Sejjil medium-range ballistic missile as part of the 54th wave of its “True Promise-4” operation, a strategically noteworthy move in the ongoing conflict involving Israel and the United States. Recent reports indicate that this is the first time the Sejjil-2 has been used in the current war, signaling a shift from deterrence to active deployment.
Israeli authorities acknowledged the incoming missile fire, reporting injuries and damage in affected areas. The launch highlights a growing intensity in exchanges, as more advanced systems are introduced into the conflict.
The Sejjil is one of Iran’s most advanced domestically developed ballistic missiles. It is a two-stage, solid-fuel medium-range (MRBM) with an estimated range of around 2,000 kilometers (about 1,240 miles), enabling it to strike targets across the Middle East, including Israel, from within Iran.
According to the , the missile can carry a payload of roughly 700 kilograms, and is about 18 meters long with a launch weight exceeding 23,000 kilograms.
Its classification as a road-mobile system further enhances its strategic value. Mobile launchers allow it to be moved, fired, and relocated quickly, reducing vulnerability to preemptive strikes.
The “dancing missile” and maneuverability
The Sejjil is often referred to as a “dancing missile,” a nickname linked to its ability to maneuver during flight. While detailed specifications remain classified, analysts note that such systems may incorporate trajectory adjustments or reentry maneuvering, making interception more difficult.
This matters because missile defense systems depend on predicting flight paths. Any mid-course or terminal maneuver reduces interception probability, especially against layered defenses.
Why solid fuel changes everything
What truly distinguishes the Sejjil from earlier Iranian missiles is its solid-fuel propulsion system. Older systems like the rely on liquid fuel that must be loaded before launch, a time-consuming process that increases the risk of detection. By contrast, solid-fuel missiles are stored in a ready-to-launch state, allowing for rapid deployment with minimal preparation time.
This reduces warning time for adversaries and significantly improves survivability. It also aligns Iran’s capabilities with modern missile doctrines, where solid-fuel systems dominate due to their responsiveness and operational flexibility.
From testing to combat use
Iran began developing the Sejjil (also linked to the earlier “Ashoura” program) in the late 1990s, with its first successful test conducted in 2008. Subsequent tests in 2009 demonstrated improvements in range and guidance.
Over time, the system evolved into one of Iran’s most advanced MRBMs, though it remained largely a strategic asset until now. Its use in the current conflict represents a turning point, indicating that systems once reserved for deterrence are now being operationally deployed.
Variants and future developments
The version believed to be used in recent strikes is the Sejjil-2, an improved iteration with better guidance and possibly reduced radar visibility. There are also unconfirmed reports of a more advanced Sejjil-3 under development, which could extend the missile’s range to around 4,000 kilometers, significantly expanding its strategic reach.
If realized, such a system would move beyond regional deterrence into a broader intermediate-range capability.
Iran’s strategic shift
The deployment of the Sejjil is not just about firepower or a display of power. It shows that Iran is now bringing its new stockpile into the field. While there are reports of already under strain, solid-fuel, mobile, and potentially maneuverable systems complicate detection and interception even further, making them deadlier in the current phase of the conflict. Whether this marks a sustained shift or a limited escalation remains uncertain, but it clearly signals that the technological threshold in the conflict is rising.
