CARRIER SURGE: USS Theodore Roosevelt Heads to Mideast as U.S. Reinforces Iran Blockade and Sustains Massive Naval Presence
The USS Theodore Roosevelt departed San Diego on Sunday for an extended deployment expected to take the aircraft carrier to the Middle East, where it will reinforce a major U.S. naval buildup as the war with Iran enters its eighth month and American forces continue enforcing a blockade against Iranian ports.
The nuclear-powered Nimitz-class carrier, the flagship of Carrier Strike Group 9, left Naval Air Station North Island and began moving west across the Pacific. A U.S. defense official confirmed that the Theodore Roosevelt had begun its planned deployment.
The carrier is expected eventually to enter the U.S. Central Command area and relieve the Japan-based USS George Washington, which was dispatched to the Middle East in August.
The Theodore Roosevelt is deploying with Carrier Air Wing 11 and a strike group that includes Destroyer Squadron 23, Information Warfare Squadron 9 and the guided-missile cruiser USS Chosin.
Its air wing includes F/A-18E and F/A-18F Super Hornets, F-35C Lightning II stealth fighters, EA-18G Growler electronic-warfare aircraft, E-2D Advanced Hawkeye command-and-control aircraft and Navy helicopters.
The deployment comes as the United States maintains an unusually large concentration of naval power across the Middle East and surrounding waters. The USS George Washington and USS George H.W. Bush carrier strike groups are currently operating in the region, while the Boxer Amphibious Ready Group is also deployed there.
The George H.W. Bush Carrier Strike Group is operating in the Arabian Sea in support of U.S. operations in the Middle East. Additional American destroyers and a cruiser are positioned in the Indian Ocean, while other U.S. warships are operating in the Red Sea and eastern Mediterranean.
The Theodore Roosevelt is expected to replace the George Washington rather than permanently add a third carrier strike group to the region, but its arrival will allow the Navy to maintain its two-carrier presence as the conflict continues.
The buildup reflects the enormous demands that the Iran war has placed on the Navy since President Donald Trump launched U.S. military operations against Iran on Feb. 28. American aircraft carriers have since played a central role in strikes, air-defense missions and maritime operations throughout the region.
The Theodore Roosevelt’s deployment also comes as Washington continues enforcing its renewed maritime blockade of Iran.
U.S. Central Command said Friday that American forces had redirected 122 commercial vessels since the current phase of the blockade began in July. Ships seeking to enter or depart Iranian ports are subject to the restrictions.
CENTCOM has emphasized that the blockade is directed at Iranian ports and does not prohibit commercial vessels from traveling through the Strait of Hormuz to non-Iranian destinations.
American officials have pushed back against Iranian claims that Tehran exercises complete control over the strategic waterway, arguing that thousands of vessels have successfully transited the strait in recent months.
The first phase of the American blockade ran from April 13 until June 18. During that period, more than 140 commercial vessels were redirected, according to CENTCOM. The blockade was subsequently resumed in mid-July, with Friday’s figure of 122 applying to the renewed operation.
The Strait of Hormuz remains one of the most consequential flashpoints in the conflict because of its enormous importance to the global energy market. Before the war, approximately one-fifth of the world’s oil supply passed through the narrow waterway linking the Persian Gulf with the Gulf of Oman.
The U.S. Energy Information Administration estimated that petroleum flows through the strait averaged approximately 21.6 million barrels per day during the final quarter of 2025. By the second quarter of 2026, amid the fighting and disruption to shipping, that figure had fallen to approximately 4.9 million barrels per day.
The agency has cautioned, however, that tracking commercial vessels in the region has become considerably more difficult since hostilities began in February, making current shipping estimates less certain.
The Roosevelt’s departure comes as another carrier, the USS Abraham Lincoln, finally makes its way home following an extraordinarily long Middle East deployment.
The Abraham Lincoln was sailing near Hawaii on Sunday as it headed toward California following more than eight months in the region without a port call. As of Monday, the carrier had been deployed for 311 days.
The Lincoln and its embarked Carrier Air Wing 9 spent months supporting U.S. military operations connected to the Iran conflict before beginning the long voyage back to the West Coast.
The extended deployment has highlighted the growing strain that sustained Middle East operations are placing on Navy personnel and their families.
“We’ve been in conflict pretty much the whole time I’ve been in the seat, and that’s certainly stressed the force. If we know we’re going into harm’s way, we should be able to project with a little bit more fidelity how long the carrier and the strike group is going to stay on station,” Chief of Naval Operations Adm. Daryl Caudle said in August.
Caudle said that repeatedly extending deployments for short periods creates particular difficulties for sailors and their families because they cannot reliably determine when service members will return home.
“We do these extensions in little chunks, and the families don’t see any end point so they can plan their own lives. That creates a lot of stress for sailors.”
Navy leadership has already been preparing Theodore Roosevelt families for the possibility that the carrier will remain away from home for an extended period.
Master Chief Petty Officer of the Navy John Perryman said in August that families connected to the Theodore Roosevelt were preparing for a deployment exceeding seven months. The carrier’s commanding officer had provided families with an eight-month estimate for planning purposes.
The new deployment comes at a particularly sensitive moment in the conflict. Washington and Tehran are again communicating indirectly through mediators in an attempt to find a formula for ending hostilities, reopening the Strait of Hormuz and addressing Iran’s nuclear program.
Iranian Foreign Minister Abbas Araghchi has presented a proposal under which the United States would end the blockade and ease economic pressure while Iran would reopen the Strait of Hormuz and resume nuclear negotiations. Trump said Saturday that he rejected Iran’s latest proposal, although both sides have indicated that further negotiations remain possible.
The continued movement of American naval forces demonstrates that Washington is simultaneously maintaining military pressure while diplomatic efforts continue.
With the Theodore Roosevelt now crossing the Pacific, the George Washington and George H.W. Bush operating in the Middle East, the Abraham Lincoln finally returning home after 311 days, and additional American surface warships positioned across surrounding waters, the Navy is continuing one of its most demanding sustained carrier operations in recent years.
