Reported shortages of basic supplies, crew morale concerns and maintenance problems aboard the USS Abraham Lincoln have intensified debate over the US Navy’s ability to sustain a prolonged war with Iran. Experts say the carrier’s conditions point to wider resupply and readiness challenges, while US officials have rejected descriptions of the situation as dire.
The Lincoln has been deployed since November 2025 and set a naval record for the longest period without a port stop. Acting US Navy Secretary Hung Cao has announced that the carrier will soon return home, with the USS George Washington moving from the western Pacific toward the Middle East as its replacement.
Reported conditions and the official response
Family members have raised concerns about the wellbeing of personnel aboard the Lincoln, including reported attempts by some personnel to jump overboard. The reported problems concern crew morale, basic supplies and maintenance rather than shortages of key offensive or defensive munitions.
The Pentagon and White House have pushed back on the characterisation of conditions as dire, describing the demands and austere environment as circumstances to be expected during wartime. Democratic lawmakers, however, have called the situation part of a broader pattern and said the Department of Defense has not adapted quickly enough to conditions in the US Central Command area of responsibility.

A resupply route stretched by attacks
Iranian attacks on US military sites, including heavy damage to a naval base in Bahrain early in the war, have complicated regional logistics. A US military official said the Navy has been using Diego Garcia in the Indian Ocean as its main supply hub.
The island is about 3,540km from the area near Iran where the Lincoln and the USS George H W Bush have been operating. Maritime security expert Alexandru Hudisteanu said the distance illustrates the logistical burden of maintaining aircraft-carrier operations when a closer resupply base is unavailable.
The carrier rotation and wider fleet pressure
The USS George Washington’s movement toward the Middle East leaves no aircraft carrier in the western Pacific, a longstanding US strategic priority. The Navy has not announced a replacement for the Washington. The three carriers identified as deployed are the Lincoln, the Bush and the Washington; the remaining carriers are based in the United States.

The USS Gerald Ford had spent 326 days deployed before rotating in May. Former naval officer Harlan Ullman said the Ford and Lincoln could each be unavailable for lengthy post-deployment refits, which typically last at least seven months but can take longer. A Center for the National Interest estimate said the San Diego-based USS Theodore Roosevelt is expected to deploy in September, while two other carriers could be available by the end of 2026 or early 2027.
Why experts say the conflict tests naval strategy
Bradley Martin, a retired US Navy captain and RAND Corporation senior policy researcher, said prolonged operations would eventually create readiness problems because the Navy has limits on how many demands it can meet. He argued that aircraft carriers are not well suited to the persistence and rotation requirements of a blockade-type operation against Iran’s drones and smaller vessels, which would require a stronger small-ship force structure.
Experts also linked the strain to the broader character of the conflict. Mona Yacoubian of the Center for Strategic and International Studies said drone-driven warfare and the vulnerability of regional bases were prompting questions about the sustainability of the US posture in the Middle East. The debate has expanded as the administration focuses its war aims on reopening the Strait of Hormuz and maintaining an indefinite blockade of Iranian ports.
