The Khorramshahr-4, also known as the Khyber, is one of Iran’s most advanced ballistic missiles, representing a significant step forward in the nation’s military and aerospace capabilities. Developed as an evolution of the earlier Khorramshahr series, this new variant is designed for long-range precision strikes and rapid launch readiness, making it an important element in Iran’s strategic arsenal.
One of the key innovations of the Khorramshahr-4 is its advanced engine, which uses hypergolic fuel. This fuel and oxidizer combination allows the missile to have a range of roughly 2,000 kilometers while carrying a payload of approximately 1,500 kilograms. Hypergolic propellants ignite spontaneously upon contact, making the missile much quicker to launch compared to those using traditional solid or liquid fuels. This unique feature reduces its launch preparation time to roughly 12 minutes, allowing for a higher degree of tactical responsiveness.
In addition, the hypergolic propellant can be stored in the missile’s tanks for long periods — potentially years — without significant degradation. This means that the missile can remain fueled and ready for deployment, a characteristic that is highly advantageous in a rapidly evolving security environment.
The Khorramshahr-4’s range allows it to cover a significant area across the Middle East and beyond, making it a credible deterrent within the regional balance of military power. Its precision and payload capacity enable it to effectively target critical infrastructure and strategic installations, providing the user with a valuable long-range strike option.
With its advanced propulsion, reduced preparation times, and long shelf life of its stored fuel, the Khorramshahr-4 demonstrates a notable technological advancement, underscoring its role as both a tactical and strategic weapon in Iran’s growing missile arsenal.
