The U.S. Navy is rotating carriers in the Middle East as the Lincoln's record-breaking deployment raises questions about fleet sustainability.
The U.S. is sending USS George Washington to the Middle East to replace USS Abraham Lincoln, which has logged more than 250 days at sea as the Iran standoff continues.
"The Lincoln is not an isolated case," Senator Richard Blumenthal, a Connecticut Democrat, wrote in an Aug. 12 letter to Defense Secretary Pete Hegseth and Acting Navy Secretary Hung Cao, citing the USS Gerald R. Ford's 326-day deployment that ended in May.
The rotation comes with less than one week remaining in the 60-day timetable agreed in the June memorandum of understanding between Washington and Tehran. Two supercarriers — Lincoln and USS George H.W. Bush — currently enforce the blockade of Iranian ports alongside more than 20 Navy warships. CENTCOM forces have redirected 55 commercial vessels, kinetically disabled two and boarded another two as of Aug. 9.
The extended carrier presence carries direct market implications. The Strait of Hormuz handles roughly 21 percent of global oil trade, and sustained U.S. naval operations in the region keep a geopolitical risk premium embedded in crude prices. Defense contractors supplying carrier-based aircraft and munitions also stand to benefit from continued operations.
Lincoln departed San Diego on Nov. 21 for what was planned as a routine Pacific deployment, then was redirected to the Middle East in January ahead of Operation Epic Fury, the U.S. bombing campaign against Iran. The carrier has since supported 40 days of continuous combat operations and gone more than 200 days without a port call — a record for consecutive days at sea, according to Navy officials.
The deployment has taken a visible toll on the roughly 5,000 sailors and Marines aboard. Family members reported food and water shortages, disrupted mail service and deteriorating mental health at town hall meetings with Cao and Vice Adms. Douglas Verissimo and Joseph Cahill in San Diego last week. One spouse told officials she received a message from her husband saying "he hopes he doesn't wake up tomorrow," according to attendees. Sailors also described an incident in which a crew member was prevented from jumping overboard.
Cmdr. Joseph Hontz, spokesperson for U.S. 5th Fleet, said the crew "remains resilient and ready to accomplish any tasking given to them," adding that the ship has "an adequate supply of food and supplies to sustain operations."
Blumenthal's letter asks the Navy to explain its carrier strike group rotation plan for the Middle East over the next 12 to 24 months, the impact on maintenance schedules and U.S. naval presence in the Indo-Pacific, and whether current deployment demands exceed what the fleet can sustainably generate. He requested a response by Aug. 27.
The George Washington, currently operating in the South China Sea after a five-day port call in Vietnam, is escorted by the guided-missile cruiser USS Robert Smalls and destroyers USS Shoup and USS Benfold. Its arrival in CENTCOM's area of operations would maintain dual-carrier coverage alongside USS George H.W. Bush.
The broader fleet picture shows the strain. Three U.S. carriers are deployed, three are working up or at homeport, four are in maintenance and one is being used for training. The USS Theodore Roosevelt returned to San Diego this month after RIMPAC 2026 and could be tapped for a Western Pacific patrol or a Middle East rotation depending on how negotiations with Iran unfold.
The last time a U.S. carrier deployment stretched this long was the Ford's 326-day tour, which ended in May and was the longest modern carrier deployment since the Vietnam era. That precedent, combined with the Lincoln's extended tour, suggests the Navy's carrier force-generation model is being tested at a level not seen in decades. President Donald Trump is reportedly leaning toward applying economic leverage over returning to all-out war, according to the Wall Street Journal, which would keep the carrier presence in the region extended but at a lower intensity than the bombing campaign phase.
