The USS George Washington, a Pacific-based aircraft carrier, is making its way toward the Middle East to relieve the USS Abraham Lincoln, whose crew of roughly 5,000 sailors has endured a gruelling nine-month deployment marked by food shortages, mental health concerns and deteriorating conditions aboard the vessel. Tracking data indicates the Washington could arrive at Duqm port in Oman — a strategic naval facility on the Arabian Sea, approximately 500 miles from the Iranian coast — around 22 August. The ship was recently spotted crossing the Strait of Malacca, the narrow waterway linking the Pacific and Indian oceans, accompanied by a cruiser and a destroyer.

The Lincoln originally departed San Diego on 21 November and arrived in the Middle East in January, ahead of the launch of US military operations against Iran on 28 February. What was initially scheduled as a six-month deployment has since stretched beyond 260 days at sea — a record-setting uninterrupted stretch — as the ship supported the ongoing US war with Iran. The Navy has acknowledged that combat operations created a "highly contested environment" that disrupted traditional supply chains, leading to shortages of fresh food and mail, as well as broken plumbing and poor sanitation. Family members of sailors have reported loved ones losing significant weight and suffering from chronic exhaustion caused by constant aircraft noise and the ship's vibrations. The Navy confirmed that a sailor went overboard in early August but was recovered and transferred for further care; it has said it has "not observed an increase in suicidal ideations or attempts aboard the ship," though it declined to provide specific data.

President Donald Trump, asked about the welfare of sailors aboard the Lincoln, dismissed concerns from families and suggested the deployment had not been long enough — "not nearly long enough," he told reporters — while confirming that a replacement vessel was en route. Defence Secretary Pete Hegseth called media reports of poor conditions "completely misrepresented" but said he wants crews rotated home as quickly as possible. Several Democratic lawmakers, including Connecticut Senator Richard Blumenthal, a member of the Senate Armed Services Committee, and Arizona Senator Ruben Gallego, a Marine Corps veteran, have called for formal oversight and investigations into conditions aboard the ship.

The George Washington's westward movement will, for an unspecified period, leave the Pacific without a US carrier presence — a strategically sensitive gap given ongoing tensions with China in the region. Once it arrives, three carriers will be operating in and around the Middle East, alongside the USS George H.W. Bush already stationed there. The Navy has reimposed a blockade on Iranian ports in the Strait of Hormuz, the critical chokepoint through which a large share of global oil flows, and Defence Secretary Hegseth has said the US can maintain that blockade "indefinitely." The Lincoln's extended deployment is not an isolated case: the USS Gerald R. Ford returned home in May after an eleven-month deployment — the longest since the Vietnam War — and other carriers have faced similar strains during sustained operations in the region.
