The aircraft carrier USS Theodore Roosevelt departed San Diego on Sunday, September 27, 2026, to deploy to the Middle East. The vessel, which serves as the flagship of Carrier Strike Group 9, is scheduled to relieve the USS George Washington in the U.S. Central Command (Centcom) region. The deployment occurs amid ongoing hostilities between the United States and Iran that began in late February 2026.
Navy officials stated the Roosevelt was prepared using lessons from the recent deployments of the USS Gerald R. Ford and USS Abraham Lincoln. The Navy expanded storage for food and hygiene products to allow the carrier to remain self-sufficient for longer periods. Chief of Naval Operations Adm. Daryl Caudle reported that a specialized team optimized the ship's climate control systems and updated software to maintain critical services if the ship is forced to operate in degraded conditions.
Recent operations in the region have focused on a U.S. naval blockade and the transit of oil through the Strait of Hormuz. U.S. Central Command reported Friday, September 25, 2026, that U.S. forces had redirected 122 commercial vessels since July to ensure compliance. On Tuesday, September 8, 2026, U.S. forces destroyed five tankers carrying Iranian crude oil following what officials described as two attempts by the Islamic Revolutionary Guard Corps to strike a U.S. Navy warship with ballistic missiles.
The scale of the military presence in the Arabian Sea involves approximately 19 U.S. warships, including the aircraft carrier USS George H.W. Bush and the amphibious assault ship USS Boxer. The economic impact is centered on the Strait of Hormuz, a waterway that U.S. military officials say has seen the passage of more than 1 billion barrels of oil over the past few months. Before the current conflict, the strait handled roughly 20 percent of the world's daily crude oil and liquefied natural gas supply, with approximately 125 commercial vessels passing through per day.
The deployment of the Roosevelt follows reported difficulties during the USS Abraham Lincoln’s 293-day deployment, which included accounts from sailors of food and water shortages and mental health concerns. The USS George Washington, which the Roosevelt will relieve, was only dispatched to the region last month. Diplomatically, Iranian Foreign Minister Abbas Araghchi recently presented a seven-day peace plan to U.S. negotiators at the UN General Assembly, though President Donald Trump rejected the proposal. U.S. aircraft carriers remain on station as officials monitor potential Iranian responses to the ongoing naval blockade.
