Iran's First Operational Use of IRBMs Targets Diego Garcia, Expanding War Theatre

Iran's targeting of Diego Garcia with ballistic missiles marks its first operational deployment of Intermediate-Range Ballistic Missiles (IRBMs), extending its military reach significantly beyond the immediate West Asia theatre. Diego Garcia, a joint US-UK military base, is approximately 4,000 km from Iran. While one missile reportedly failed mid-flight and the other was intercepted by a US Navy warship's SM-3 interceptor, this event signifies Iran's disclosure and deployment of such long-range capabilities. IRBMs, with a range of 3,000-5,500 km, bridge the gap between medium and long-range missiles, posing new strategic challenges.
