Iran Tests Extended Missile Range With Failed Strike on Diego Garcia U.S.–British Base
Iran attempted a long‑range missile strike on Friday against the joint U.S.–British military base at Diego Garcia in the Indian Ocean, firing two missiles roughly 2,500 miles from Iranian territory, according to U.S. and Western officials. One missile reportedly failed mid‑flight and the other was intercepted by an American warship, but the launch surprised U.S. planners because the distance exceeds the range usually attributed to Iran’s ballistic arsenal. Missile‑defense analyst Tom Karako of the Center for Strategic and International Studies said the shot was "beyond what we and they usually advertise," yet current Iranian missiles still cannot reach the U.S. homeland, contrary to some online speculation. A senior Western military official suggested Tehran may be trying to force Washington to disperse its missile defenses beyond Middle East bases, complicating U.S. war planning as Britain prepares to expand American access to its bases, including Diego Garcia. The episode underscores both the growing reach and the limits of Iran’s missile program, and it will feed directly into debates over U.S. basing and missile‑defense posture in the wider Iran conflict.
