The real story behind the USS Lincoln's troubled deployment

The USS Abraham Lincoln has begun its roughly 21,000-km return to home port San Diego, bringing to a close a 272-day deployment that stretched considerably beyond what had originally been planned. The USS George Washington has arrived in the Middle East to take its place. Although the rotation itself is explained as routine, the manner in which it unfolded points to deeper strains in how the US Navy is currently able to sustain its carrier presence across multiple theatres.

The Lincoln departed its home port in November 2025 and, over the course of its deployment, became engaged in high-intensity combat operations and a sustained naval blockade against Iran, as part of the ongoing war. What was intended as a standard deployment was extended well beyond its expected duration, leading to logistical and welfare problems that developed over the months.

The problems started to aggravate after Iran inflicted severe damage on a US Navy logistics hub in Manama, Bahrain, which disrupted the ship's supply chain for an extended period and left the crew without reliable access to essential goods. Families of the crew, along with several members of Congress who took up the matter, subsequently described conditions on board that included food and water shortages, contaminated water supplies, plumbing failures, the presence of mould in living quarters and repeated disruptions to mail delivery. Sailors went more than 240 consecutive days without a single port call or day off, a stretch that appears to have taken a significant toll on morale. Reports later emerged of sailors contemplating, or in some cases attempting, to commit suicide, though the exact number of such incidents has not been made public. Admiral Brad Cooper of US Central Command characterised these reports as old news, although the underlying conditions were clearly serious enough.

In response, the Pentagon ordered the USS George Washington to leave its home port in Yokosuka, Japan, and proceed to the Arabian Sea, a redeployment that required the ship to cover a considerable distance in a relatively short window. It arrived in the Central Command area of responsibility on August 19 and subsequently joined the USS George H.W. Bush in maintaining the ongoing blockade of Iranian ports. Officials off the record have described the move as a last-resort measure intended to relieve the Lincoln, rather than a planned or strategically motivated redeployment.

The episode reflects a set of broader constraints affecting the carrier fleet as a whole. The United States maintains 11 nuclear-powered supercarriers, but only a few are available for combat duty at any given time. Longer maintenance schedules, limited shipyard capacity and training requirements keep ships out of active service. For instance, the USS John C. Stennis and USS Harry S. Truman  have been unavailable for some time as they are undergoing extended overhauls. The newer Ford-class carriers, which were meant to ease some of this pressure, have themselves faced repeated construction delays.

The prolonged conflict in the Middle East has placed further strain on an already constrained rotation and maintenance schedule. Longer deployments of the kind experienced by the Lincoln tend to result in greater wear on critical systems, which in turn leads to longer repair times. The volume of missiles, precision munitions and fuel expended during operations against Iranian targets have shown the limits of how many fronts the Pentagon can sustain simultaneously.

The redeployment of the George Washington carries a direct consequence for the Indo-Pacific region. For the first time in several decades, the Western Pacific is without a forward-deployed US carrier strike group, despite the Pentagon has for some years identified this region as a strategic priority.

Analysts have noted that this absence creates a window that could be used by China to increase coercive patrol activity near Taiwan, the Philippines or the South China Sea, while also allowing Beijing to characterise the temporary US absence as evidence of reduced regional commitment. North Korea may see a similar opportunity to test the responsiveness of regional forces during this interval.

The shift has already drawn attention from regional allies. Japan and the Philippines are among the countries currently assessing how quickly US reinforcements could realistically be deployed in the event of a regional crisis. In South Korea, existing concerns have been compounded by the decision to scale back the Ulchi Freedom Shield exercises, a move the Trump administration has framed as consistent with its broader approach to allied burden-sharing.

These developments may over time prompt allies to reconsider aspects of their own defence planning, including a greater emphasis on submarines and land-based systems that do not depend on the continuous availability of a single, heavily committed carrier group.
