MANAMA, July 12 — The United States Fifth Fleet, operating from its headquarters at Naval Support Activity Bahrain, remains the principal American naval force ensuring maritime security across the Persian Gulf, Gulf of Oman, and Red Sea. Under the operational command of U.S. Central Command (CENTCOM), the fleet’s mission is to deter aggression and guarantee free passage under international law, including the 1982 United Nations Convention on the Law of the Sea (UNCLOS), to which Iran is a signatory.
Since its re-establishment in 1995, the Fifth Fleet has maintained a formidable presence in one of the world’s most strategically vital waterways. Its typical order of battle includes an aircraft carrier strike group, amphibious ready groups, and dozens of surface combatants.
Among the assets routinely deployed are Arleigh Burke-class destroyers, such as the USS Mitscher, and the USS Dwight D. Eisenhower carrier strike group. In 2023 alone, the fleet conducted 14 freedom-of-navigation operations (FONOPs) in the Strait of Hormuz.
Command and Allied Coordination
As of 2024, the fleet’s commander is Vice Admiral George Wikoff. He coordinates not only with CENTCOM but also with allied navies through the International Maritime Security Construct (IMSC), established in 2019. The IMSC includes the United Kingdom, Australia, and Bahrain itself.
The fleet’s operations are grounded in the provisions of UNCLOS, which codifies the right of innocent passage through territorial seas and transit passage through straits used for international navigation. Iran, as a signatory, is bound by these rules.
The IMSC, meanwhile, provides a multilateral framework for burden-sharing. The involvement of the United Kingdom and Australia brings additional naval assets and political weight, while Bahrain’s participation as a host nation underscores the local dimension of the security challenge.
What to Watch
As the Fifth Fleet continues its patrols and exercises, the key indicators to monitor are the frequency and nature of Iranian interactions with allied vessels. Any escalation in the Strait of Hormuz would test the fleet’s capacity to respond under Vice Admiral Wikoff’s command.
