🇺🇸⛴📉 U.S. Navy’s Supercarriers Disappear Into Shipyard for Years A Nimitz-class aircraft carrier reaches middle age after roughly 25 years. The Navy then sends it to the only American shipyard capable of refueling its reactors, and the vessel disappears from the operational fleet for five or even six years. The process is called a Refueling and Complex Overhaul (RCOH). Workers at Newport News Shipbuilding must cut controlled access routes through the 100,000-ton ship to reach two nuclear reactors buried behind armor, shielding, machinery and structural compartments. Once the carrier has been opened, the flight deck, catapults, propulsion system, radars, electronic warfare equipment, electrical networks and thousands of pipes and valves are repaired or replaced. One overhaul can consume around 25 million labor hours and account for 35% of all maintenance and modernization performed during a carrier’s 50-year life. The bill runs into several billion dollars. Recent projects show how quickly the schedule can slip. USS George Washington entered Newport News in August 2017 under a $2.8B contract and emerged 69 months later. USS John C. Stennis began its $3B overhaul in May 2021. Its original delivery date was August 2025; the Navy now expects it back in October 2026. USS Harry S. Truman is preparing for the next overhaul. Another carrier will spend years unavailable for deployment while consuming money, shipyard capacity and thousands of workers. Newport News is the central weakness in the system. It is the only yard that performs carrier RCOHs. A workforce shortage, supplier delay or unexpected damage found inside one ship can disrupt the schedule for the vessels waiting behind it. No second facility is ready to absorb the work. The effects spread through the fleet. Remaining carriers cover more deployments, stay away from port longer and fit training and maintenance into tighter schedules. USS Abraham Lincoln has just reached Thailand after 286 days at sea, including combat operations during the war against Iran. Keeping one carrier deployed for that long solves an immediate problem and creates the next maintenance bill. The transition to the Ford class has brought another delay. The Navy extended the service life of USS Nimitz into 2027 to bridge the gap until the new USS John F. Kennedy is delivered. The Pentagon can assign ships to the Pacific, Middle East and Europe on a map. A carrier trapped behind scaffolding in Virginia contributes nothing to any of those theaters. Washington built its global military posture around the assumption that a supercarrier would always be available when a crisis began. Only one American shipyard can perform these overhauls, and its schedule is already measured in five-year blocks. The usable fleet is considerably smaller than the official ship count suggests. @NewRulesGeo❗Follow us on X
