Sejjil Missile of Iran – Home Academy Defence Update

Introduction

The Sejjil missile is one of the most advanced ballistic missiles developed by Iran. It represents a major technological shift from liquid-fuel to solid-fuel missile systems, making it faster, more reliable, and combat-ready in a short time. This missile plays a significant role in Iran’s strategic deterrence capability in the Middle East.

Development Background

The Sejjil missile program was initiated in the late 1990s as part of Iran’s effort to modernize its missile arsenal. It was first successfully tested in 2008, followed by improved tests in subsequent years.

The development of Sejjil marked Iran’s transition from older missiles like Shahab missile (liquid-fueled) to advanced solid-propellant systems, which are more efficient and difficult to intercept.
