- Kheibar: Another long-range missile, the Kheibar, can reach targets up to 2,000 kilometers (1,240 miles) away. It provides Iran with the ability to strike regional adversaries, including Israel, with precision.
- Haj Qasem: With a range of 1,400 kilometers (870 miles), the Haj Qasem missile is another key component of Iran’s missile capabilities. It offers a balance between range and accuracy, making it suitable for regional operations.
Overview of Iran’s Ballistic Missile Ranges
The Arms Control Association, a prominent non-governmental organization, has detailed Iran’s extensive ballistic missile inventory:
- Shahab-1: This missile has an estimated range of 300 kilometers (190 miles). It is a short-range option primarily used for regional conflicts.
- Zolfaghar: Capable of striking targets at a distance of 700 kilometers (435 miles), this missile is more advanced than the Shahab-1.
- Shahab-3: With a range between 800 and 1,000 kilometers (500 to 620 miles), the Shahab-3 provides Iran with a medium-range option for targeting regional adversaries.
- Emad-1: Currently under development, the Emad-1 is designed to reach distances of up to 2,000 kilometers (1,240 miles).
- Sejil: In addition to the longer-range variant, another version of the Sejil is under development, with a range between 1,500 and 2,500 kilometers (930 to 1,550 miles).
Iran’s Missile Launch Methods: Solid vs. Liquid-Fueled Technology
Iran’s missile arsenal includes both solid-fuel and liquid-fuel missiles, each with distinct advantages:
- Solid-Fuel Missiles: These missiles are generally more advanced due to their rapid launch capabilities. They are often deployed from mobile, angled launchers, providing flexibility and reducing the time required for launch preparation. Solid-fuel missiles, such as the Haj Qasem, Kheibar Shekan, and Fattah 1, were reportedly used during the October 1 strike on Israel.
- Liquid-Fuel Missiles: These missiles, while older in design, remain a key part of Iran’s arsenal. They are typically launched from fixed, vertical platforms. Reports indicate that during the October 1 strikes, Iran launched liquid-fueled missiles, including the Emad, Badr, and Khorramshahr, from Isfahan.
The Strategic Role of Iran’s Missile Capabilities
Iran’s ballistic missiles serve as both a deterrent and a retaliatory tool against perceived threats, including the U.S., Israel, and other regional adversaries. Despite international concerns, Iran maintains that its missile program is solely for defensive purposes, not for developing nuclear capabilities.
A 2023 report by Behnam Ben Taleblu, a Senior Fellow at the Foundation for Defense of Democracies, highlighted Iran’s ongoing efforts to enhance its missile infrastructure. This includes developing underground missile storage facilities, transport systems, and even production centers. Notably, Iran demonstrated its ability to launch ballistic missiles from underground sites in 2020, showcasing its technological advancements.
Advancements in Hypersonic Missile Technology
In June 2023, Iran unveiled what it described as its first domestically produced hypersonic ballistic missile. Hypersonic missiles are known for their ability to travel at speeds at least five times faster than the speed of sound, following complex trajectories that make them difficult to intercept. This development marks a significant step forward in Iran’s missile technology, potentially altering the balance of power in the region.
The Influence of External Partnerships
Iran’s missile program has been heavily influenced by foreign technology, particularly from North Korea, Russia, and China. The Arms Control Association notes that many of Iran’s missile designs are derived from North Korean and Russian models, while China has provided technical assistance in key areas. These partnerships have allowed Iran to refine and expand its missile capabilities over the years.
Iran’s Regional Missile Operations
Iran has not hesitated to use its missile capabilities in regional conflicts, furthering its strategic interests. Some of the notable instances include:
- Strikes in Iraq and Syria: In January 2024, Iran’s Revolutionary Guards launched missile strikes targeting what they identified as Israeli spy headquarters in Iraq’s Kurdistan region. Additionally, Iran has used missile strikes against Islamic State militants in Syria, demonstrating its willingness to project power beyond its borders.
- Attacks in Pakistan: Iran has also used missile strikes against Baluchi militant bases in neighboring Pakistan, highlighting its efforts to counter perceived threats along its borders.
- 2019 Saudi Arabia Attacks: The United States and Saudi Arabia accused Iran of orchestrating a missile and drone attack on key Saudi oil facilities in 2019. While Iran denied involvement, the incident underscored the potential reach of its missile program.
Iran’s Missile Support for Allied Forces
Iran’s missile capabilities are not only used directly but are also transferred to allied groups in the region, further complicating the security landscape. Two key examples include:
Backing for Yemen’s Houthis
The United States accuses Iran of providing ballistic missiles and other weaponry to Yemen’s Houthi rebels. The Houthis have used these weapons to launch attacks on shipping routes in the Red Sea and to target Israel amid the ongoing Gaza conflict. Tehran denies supplying arms to the Houthis, but reports indicate that Iran facilitated secret talks with Russia to transfer anti-ship missiles to the Houthis2, the Houthis launched a missile attack on the United Arab Emirates, targeting a U.S. military base. However, U.S.-built Patriot interceptor missiles successfully thwarted the attack, showcasing the ongoing missile arms race in the region.
Support for Hezbollah in Lebanon
Lebanon’s Hezbollah, a powerful paramilitary group backed by Iran, has become a significant player in the region. The group has boasted of its ability to convert conventional rockets into precision-guided missiles with the assistance of Iranian experts. This capability poses a direct threat to Israel, which has long been in conflict with Hezbollah.
In a critical blow to Hezbollah, its leader, Hassan Nasrallah, was killed in an Israeli airstrike on September 27, 2024. The group’s missile capabilities, however, remain a key aspect of Iran’s strategy to maintain pressure on Israel through proxy forces.
Iran’s Role in Syria’s Missile Capabilities
Iran has also played a pivotal role in enhancing Syria’s missile capabilities. Intelligence reports suggest that Iran has transferred precision-guided missiles to Syria, providing support to President Bashar al-Assad in his battle against various rebel factions. Additionally, Iran has helped establish underground missile production facilities in Syria, enabling pro-Iranian forces to produce their own missiles. This has significantly bolstered Syria’s ability to confront opposition forces and deter potential attacks from regional adversaries.
