Iran fires ballistic missile at U.S. base in Jordan, says retaliation for US airstrike

Iran launched several ballistic missiles at United States military bases in Jordan in the early hours of Wednesday, targeting the Ameinik Air Force Base near the city of Arab and an army outpost in Wadi al‑Hasir. The Islamic Revolutionary Guard Corps (IRGC) Ground Forces Command said the strike was a “direct response” to recent U.S. airstrikes in Iraq and Syria against Iran‑backed armed groups, and warned that the United States would face “larger‑scale” military action if it does not withdraw from the Middle East. The U.S. Department of Defense reported that the missiles caused no substantive damage to the facilities and that air‑defence systems intercepted some of the warheads.

A ballistic missile is a weapon that, after launch, travels most of its trajectory without propulsion, relying on inertia and gravity to follow a parabolic path. Depending on range, they are classified as short‑range ballistic missiles (SRBMs) or longer‑range types, including intercontinental ballistic missiles (ICBMs). Unlike cruise missiles, ballistic missiles fly outside the atmosphere, attain higher speeds and destructive power, and are more difficult to track and intercept with radar. Iran now possesses the capability to develop and deploy medium‑range ballistic missiles; the missiles used in this attack appear to have been Zolfaghar or a similar short‑range type with an estimated range of 300‑500 km, sufficient to reach U.S. installations throughout Jordan.

The launch occurred against a backdrop of heightened tension in the region. Since the end of 2023, the United States has intensified aerial campaigns in Iraq and Syria, conducting “precision strikes” against Iran‑supported militias and Iran’s nuclear and missile programs. Iran has responded with both rhetoric and concrete actions, including missile tests over the Persian Gulf and Saudi Arabian airspace and the deployment of air‑defence systems inside Iraq. Jordan, a key U.S. ally on the Arabian Peninsula, has long provided logistical and intelligence support to American forces and has become a focal point of Iran’s warnings.

International reactions have been divided. The European Union and the United Nations have called on all parties to exercise restraint and avoid escalation, while the United States and its NATO partners have condemned Iran’s actions as provocative and pledged to bolster defensive deployments in the Middle East. Iran’s foreign ministry reiterated a “zero‑tolerance” stance toward the U.S. military presence and accused Washington of pursuing “military hegemony” that undermines regional stability. This missile salvo may prompt the United States to reassess its force posture in Jordan and across the broader Middle East.

For Taiwan, the incident underscores the pivotal role of missile technology in regional conflicts and reinforces the need for continued investment in air‑defence and missile‑defence capabilities. Although Taiwan is geographically distant from the Middle East and has limited direct stakes, rising tensions there could affect global energy supplies and international financial markets, thereby influencing Taiwan’s energy costs and export environment. Moreover, Iran’s use of medium‑range ballistic missiles demonstrates that even weapons of modest range can exert strategic deterrence against distant targets, offering a case study relevant to Taiwan’s own defence planning and strategic assessments.
