U.S. forces struck Iranian cruise-missile storage and coastal-defense systems on Greater Tunb on July 15, 2026 [1].
The operation targets a critical chokepoint for global trade. Control of the islands allows Iran to monitor and potentially threaten the heavy flow of commercial shipping through the Strait of Hormuz [2].
The strike focused on Greater Tunb, one of three disputed islands in the region [3]. These islands, Greater Tunb, Lesser Tunb, and Abu Musa, sit at the confluence of the Persian Gulf and the Gulf of Oman [4]. While the United Arab Emirates claims the islands, Iran has controlled them since seizing them in 1971 [5].
Washington said the strikes hit cruise missile storage and coastal defence systems, aiming to curb Iran's ability to threaten shipping [6]. A U.S. military spokesperson said Wednesday it had attacked Iranian cruise missile storage and launch sites on Greater Tunb [1].
The strategic importance of the area is underscored by the volume of energy transit. Approximately one-fifth of global oil passes through the Strait of Hormuz [7]. Because of this vulnerability, the U.S. military has previously evaluated security measures for the waterway.
On March 10, 2026, Gen. Dan Caine said, "We are looking at ways to escort ships safely through the Strait of Hormuz" [8]. The recent strikes represent a shift from planning escorts to actively degrading the infrastructure Iran uses to monitor and target vessels in the strait.
“The U.S. military said Wednesday it had attacked Iranian cruise missile storage and launch sites on Greater Tunb.”
The U.S. strike on Greater Tunb signals an escalation in the effort to ensure the freedom of navigation in one of the world's most vital maritime corridors. By targeting the physical infrastructure of Iran's coastal defenses, the U.S. is attempting to neutralize Iran's tactical advantage provided by the 1971 seizure of the islands, reducing the risk of a blockade or targeted attacks on oil tankers that could destabilize global energy markets.
