The Iranian Sejjil ballistic missile is a two-stage, solid-fueled medium-range missile that represents a significant advancement in Tehran's missile program.
Unlike older liquid-fueled systems, Sejjil’s solid fuel allows for rapid launch readiness and increased survivability, as it can be stored and fired from mobile transporters with minimal preparation.
The Sejjil ballistic missile has an estimated range of 2,000–2,500 kilometers and a payload capacity of up to 1,000 kilograms. It can strike targets across the Middle East with relatively high accuracy.
