Here’s TWZ’s weekly carrier tracker monitoring America’s flattop fleet, including deployed Carrier Strike Groups (CSG) and Amphibious Ready Groups (ARG), using publicly available open-source information. Check out last week’s report here.
The U.S. naval blockade of Iranian ports remains in full effect, for now, pending the execution of the ceasefire agreement, scheduled to be formally signed on Friday in Geneva, according to a notice released today by NAVCENT. U.S. Central Command (CENTCOM) forces launched multiple waves of strikes last week against Iran following the shootdown of a U.S. Army Apache helicopter, and disabled an additional two commercial vessels that tried to skirt the blockade, bringing the total to nine. Two carriers, USS Abraham Lincoln and USS George H.W. Bush, embarked with a combined seven squadrons of F/A-18E/F Super Hornets, two squadrons of EA-18G Growlers, and one squadron of F-35C Lightning IIs, continue to support “self defense” strikes and blockade operations.

The Lincoln CSG has been deployed for nearly seven months and would likely be among the first naval assets to rotate out of the theater if the blockade winds down. The details, and scale, of the drawdown of forces in the CENTCOM area of responsibility (AOR), as agreed upon in the memorandum of understanding (MOU), are murky as of publication. More than 20 U.S. Navy surface combatants have been operating in the region.
USS Nimitz entered the final leg of her homeport shift to Norfolk, operating off the east coast in U.S. 2nd Fleet AOR after a monthslong circumnavigation of South America, according to flight tracking data and public AIS. Nimitz conducted operations northwest of Cuba and the Bahamas last week. On Thursday, six Super Hornets, attached to the “Kestrels” of Strike Fighter Squadron (VFA) 137, carried out an air power demonstration and show of force, dropping MK-82/BLU-111 bombs on a simulated target in the Gulf of America.
On the west coast, USS Theodore Roosevelt continues working up in preparation for a future deployment. The flattop got underway on June 10 for INSURV inspections to verify readiness and returned to San Diego the following day. The group was also spotted conducting a live fire exercise with the Mk 38 25mm machine gun. USS Carl Vinson got underway for sea trials after a nine-month Planned Incremental Availability (PIA) and moored at port in San Diego on June 13.
In the Western Pacific, USS George Washington is on a summer patrol and operating in the Philippine Sea. The CSG conducted a replenishment-at-sea with USNS Earl Warren and helo operations while underway in the vicinity of Guam last week. Destroyer USS Shoup, part of the CSG, pulled into Apra Harbor early this morning, according to AIS.
Two ARG-MEUs are currently deployed. Forward-deployed USS Tripoli continues operations in the CENTCOM AOR, and USS Boxer is underway in the Indo-Pacific (INDOPACOM) AOR, operating in the South China Sea. For a detailed review of America’s amphibious assault fleet, check out our recent report here.
Note: Positions are general approximations. Non-deployed LHA/LHD amphibious warships are not shown.
