NEWPORT NEWS, Va. — The USS John C. Stennis ship, a Nimitz-class aircraft carrier, has successfully completed a significant phase in its Refueling and Complex Overhaul (RCOH). Newport News Shipbuilding (NNS), a division of HII, announced the completion of the dry dock portion of the RCOH for the USS John C. Stennis (CVN 74).
Following the earlier flooding incident where over 100 million gallons of water entered the dry dock, the USS John C. Stennis was successfully relocated to an outfitting berth at the shipyard. Here, the remaining RCOH work and comprehensive testing will be finalized, marking a major step forward in the ship’s revitalization.
“Witnessing Stennis depart the dry dock and return to the water reflects the dedication of our shipbuilders, the ship’s crew, and our government collaborators,” stated Rob Check, Vice President of In-Service Aircraft Carrier Programs at NNS. “Our attention remains firmly on the tasks ahead during this RCOH period, as we are dedicated to preparing this formidable aircraft carrier for the next chapter of its operational service.”
Dry Dock Phase Completion and Ship Relocation
The dry dock phase of the RCOH for the USS John C. Stennis was marked by substantial upgrades and a comprehensive overhaul process, impacting both the interior and exterior of this significant naval vessel. This phase saw the successful defueling and subsequent refueling of the ship’s nuclear power plant, a critical element of the RCOH.
In addition to the complex power plant work, NNS shipbuilders undertook extensive preservation of tanks and the replacement of numerous essential components. This included thousands of valves, pumps, and piping components, ensuring the reliability and longevity of the ship’s systems.
Extensive Upgrades During Dry Dock
The exterior of the USS John C. Stennis also received considerable attention during the dry dock phase. Shipbuilders completed major structural enhancements to key areas, including the island, mast, and antenna tower, modernizing these critical structures. Furthermore, all aircraft launch and recovery equipment underwent upgrades, ensuring the John C. Stennis remains at the forefront of naval aviation capabilities.
Additional exterior work included a complete painting of the ship’s hull, encompassing sea chests and freeboard, enhancing protection and reducing corrosion. The propeller shafts were meticulously restored, and refurbished propellers and rudders were expertly installed, optimizing the ship’s propulsion efficiency.
Continuing the Overhaul: Next Phase at Outfitting Berth
With the dry dock phase now complete, the USS John C. Stennis has moved to the outfitting berth for the next crucial stage of its RCOH. Shipbuilders will now focus on completing the overhaul and installation of the ship’s major components. A significant aspect of this phase involves rigorous testing of the ship’s sophisticated electronics, combat, and propulsion systems, ensuring all systems meet stringent operational standards.
This phase of the RCOH also prioritizes enhancements to the living conditions onboard the John C. Stennis. Improvements to crew living spaces, galleys, and mess decks are planned, reflecting a commitment to the well-being and operational effectiveness of the ship’s company.
“Our commitment remains unwavering to return our ship to operational readiness and to support the professional and personal growth of our sailors,” commented Capt. J. Patrick Thompson III, Commanding Officer of USS John C. Stennis. “We look forward to continued collaboration with our industry partners to finalize production and testing, and to redeliver Stennis to the fleet.”
USS John C. Stennis and the RCOH Program
The USS John C. Stennis represents the seventh Nimitz-class aircraft carrier to undergo the RCOH program. This mid-life refueling overhaul and maintenance availability is essential for producing a recapitalized carrier capable of meeting the evolving demands of the U.S. Navy. Upon completion of the RCOH, the USS John C. Stennis will be equipped to serve in the fleet for the second half of its anticipated 50-year service life, continuing its vital role in naval operations for decades to come.
