National Interest – Deterring regional adversaries from threatening Iran is the primary reason Tehran has amassed the largest ballistic missile force in the Middle East.
The missile program actually began under the Shah, but it was accelerated during the Iran-Iraq War in order to threaten Saddam Hussein with strikes deep in Iraqi territory. Since then, Iran has worked with countries like Libya, North Korea and China in order to develop a large and diverse arsenal of ballistic and cruise missiles that form one part of its three-leg deterrent strategy. With Iran now using missiles in conflict, it’s worth taking a closer look at the weapons in its arsenal.
Shahab-Series: The backbone of Iran’s missile forces are the Shahab-series of liquid-fueled (mostly) short-range ballistic missiles (SRBM). There are three variants of the missile: The Shahab-1, Shahab-2 and Shahab-3. The Shahab-1 was the first missile Iran acquired and is based on the Soviet Scud-B missile. Iran reportedly purchased these initially from Libya and possibly Syria, but North Korea has been its main supplier. The Shab-1 has a reported range between 285–330 kilometers, and can carry a warhead of around one thousand kilograms. Iran is believed to have three hundred Shahab-1 rockets.
Later Iran acquired Shahab-2 missiles, likely from North Korea. This missile is based on the Scud-C and has a range of five hundred kilometers with a payload capacity of 770 kilograms. Iran first began testing the Shahab-2 in 1998, and it has been operational since at least 2004. Like the Shahab-1, the Shahab-2 is road-mobile, however, the Congressional Research Service has noted that: “Wartime experiences, such as in Iraq, show these missiles tend to operate within a radius of about 100 kilometers or less from their bases because of the need to ensure operational security and to be able to maintain key logistics support.” Tehran only purchased between 100–170 Shahab-2s from North Korea, but can now produce them indigenously (although it relies on some imported parts).
