On April 8, the Nimitz-class aircraft carrier undocked, marking the transition from dry dock to the shipyard’s outfitting berth. This movement signifies the completion of a crucial phase in the $3 billion overhaul, which began in May 2021 and is now over 65 percent complete. The carrier is on track for redelivery in October 2026.

Commissioned in December 1995, the USS John C. Stennis is undergoing its mid-life RCOH, a comprehensive process involving upgrades to propulsion equipment, infrastructure, and electronic systems. The dry dock flooding involved over 100 million gallons of water, and the ship will now see the installation and testing of major components and combat support systems.

Capt. Mark Johnson, manager of the PEO Aircraft Carriers In-Service Aircraft Carrier Program Office, noted that lessons from previous RCOHs, particularly that of the USS George Washington (CVN 73), are being applied to streamline the process. The Navy-Industry team is leveraging digital management tools and processes to support the workforce.

The USS John C. Stennis’ RCOH involves over 25 million man-hours, with extensive upgrades including a new square and tapered mast, modernized defense and communications systems, updated shafts, refurbished propellers, and enhanced aircraft launch and recovery equipment.

During the upcoming outfitting and testing phase, shipbuilders will focus on completing the overhaul and ensuring the ship’s electronics, combat, and propulsion systems are fully operational. Improvements will also be made to the living areas and general quality of life for the sailors, including upgrades to crew living spaces, galleys, and mess decks.

The carrier's flight deck spans over 4.5 acres and can accommodate more than 70 aircraft, including F/A-18 Hornets, EA-18G Growlers, and E-2C Hawkeyes. Its complement includes a crew of approximately 3,200 sailors, with an additional 2,480 personnel from the embarked air wing.

Throughout its service, the USS John C. Stennis has participated in numerous military operations and exercises. It has been deployed to various regions, including the Persian Gulf, the Western Pacific, and the Indian Ocean, supporting U.S. interests and demonstrating naval presence. Notable deployments include operations in support of Operation Enduring Freedom in Afghanistan and Operation Iraqi Freedom.
