Iran's Islamic Revolutionary Guard Corps launched anti-ship missiles from Qeshm Island and the Sirik area on its southern coast toward the Strait of Hormuz and the Gulf of Oman, adding to a string of military moves around a waterway that carries about a fifth of global oil supply. Qeshm, Iran's largest island in the Persian Gulf, sits at the mouth of the strait and has been built up as a fortified launch platform with underground missile storage facilities that Tehran revealed in 2021; satellite imagery from March 2026 showed anti-ship missile systems deployed there. The source links the latest launches to earlier incidents in 2026, including reported fire at an oil tanker near Oman's coast on August 10, Iranian claims in June that launches were directed at U.S. naval vessels, U.S. Central Command denials, and subsequent U.S. counterstrikes and operations against missile infrastructure on the island between May and July. The strait handles about 21 million barrels of oil a day and is only about 21 miles wide at its narrowest, with two-mile inbound and outbound shipping lanes, helping explain why even limited attacks in the area can quickly raise risks for energy markets.
