More than 20 U.S. Navy warships are enforcing a blockade of Iran in the U.S. Central Command (CENTCOM) area of responsibility, and CENTCOM says it has redirected 61 commercial vessels and disabled at least four attempting to run the blockade.
CENTCOM numbers and public accounting
CENTCOM made its tally public in a May 10, 2026 post, reporting that its forces have redirected 61 commercial vessels linked to Iran and disabled at least four attempting to run the blockade. The same release and imagery show over 20 U.S. warships operating in the CENTCOM AOR to enforce the maritime measures. The CENTCOM feed also photographed USS John Finn (DDG 113) following USS Milius (DDG 69), USNS Carl Brashear (T‑AKE‑7), and USS George H.W. Bush (CVN 77) in the Arabian Sea.
USS George H.W. Bush CSG: flight operations in the Arabian Sea
The U.S. Navy released images showing USS George H.W. Bush conducting flight operations in the Arabian Sea on May 6, 2026. Carrier Air Wing 7 aircraft visible on the flight deck included 25 F/A‑18E/F Super Hornets, two E‑2D Hawkeyes, and three MH‑60 Seahawks. The Navy note accompanying the photographs specifies that, unlike the Abraham Lincoln CSG operating in the same AOR, George H.W. Bush is not equipped with carrier-based F‑35C aircraft.
Gerald R. Ford CSG: extended deployment and westward transit
Gerald R. Ford Carrier Strike Group transited the Strait of Gibraltar westbound on May 6 and is steaming toward Norfolk. As of May 11, the strike group had been deployed for 322 days. The CSG departed Norfolk in June 2025 and was initially scheduled to return in January 2026; the deployment was extended twice to support combat operations in the Caribbean and the Middle East.
Other carrier movements and training: Eisenhower, George Washington, Theodore Roosevelt, Nimitz
Three carriers were reported underway for training or transit:
- Dwight D. Eisenhower CSG is working up off the U.S. east coast following a 15‑month availability, operating with AIS turned on.
- George Washington CSG got underway on May 10, departing Yokosuka, Japan, and was reported escorted by guided‑missile cruiser USS Robert Smalls.
- Theodore Roosevelt CSG was conducting "advanced training to bolster strike group readiness and capability" in the Pacific; the Navy published a May 4 photo of flight operations.
Separately, USS Nimitz was anchored off Rio de Janeiro, Brazil, for a five‑day liberty port call on May 7 while circumnavigating South America en route to a new homeport in Norfolk. The reporting notes that Nimitz’s service life was extended into 2027 after earlier plans to decommission her this year.
Boxer ARG and the 11th Marine Expeditionary Unit: an incoming expeditionary boost
An additional Marine Air‑Ground Task Force is set to arrive in CENTCOM in the near term. The Boxer Amphibious Ready Group (ARG) had not been confirmed in CENTCOM as of publication, but the reporting says an arrival announcement could come as soon as next week. Embarked aboard Boxer is the 11th Marine Expeditionary Unit (MEU), composed of a command element; a Ground Combat Element, Battalion Landing Team 3/5; an Aviation Combat Element with two squadrons — Marine Medium Tiltrotor Squadron (VMM) 163 (Reinforced) and Marine Fighter Attack Squadron (VMFA) 122 — and a logistics combat element. The reporting estimates roughly 5,000 Marines and Sailors aboard Boxer; those forces are expected to join the Tripoli ARG already on station in the Middle East and to "significantly enhance the United States’ expeditionary capabilities in the region."
What this means for CENTCOM, carrier air wings, and expeditionary forces
- CENTCOM and policymakers: The publicized figures — 61 redirected vessels and four disabled — are the operational results CENTCOM is using to describe enforcement to date; the planned arrival announcements (for example, Boxer ARG) and Gerald R. Ford’s westbound transit are immediate, named developments that will affect force posture in the coming days.
- Carrier air wings: Visual confirmation of George H.W. Bush’s Air Wing 7 composition (25 F/A‑18E/F, two E‑2D, three MH‑60) and the contrast drawn with Abraham Lincoln CSG’s F‑35C capability highlight differing organic aviation mixes across CSGs operating in the region.
- Expeditionary forces (Boxer ARG / Tripoli ARG / 11th MEU): The arrival of roughly 5,000 Marines and Sailors aboard Boxer would materially increase amphibious and aviation lift available to CENTCOM and join an already deployed ARG in the region.
The immediate picture, as of May 11, 2026, is a concentrated U.S. naval presence enforcing maritime measures in CENTCOM waters: over 20 warships on station, two carrier strike groups actively involved, and expeditionary reinforcements that could be announced as soon as next week. CENTCOM’s published counts — 61 commercial vessels redirected and at least four disabled — are the concrete operational markers available now; whether incoming amphibious forces or the Gerald R. Ford CSG’s return to Norfolk will shift enforcement patterns remains a named, near‑term development to watch.
