HII’s Newport News Shipbuilding division has completed the dry dock portion of the refueling and complex overhaul (RCOH) of Nimitz-class aircraft carrier USS John C. Stennis (CVN 74).

Following the recent flooding of more than 100 million gallons of water into the dry dock, USS John C. Stennis was moved to an outfitting berth at the shipyard, where the remainder of the RCOH work and testing will be completed.

During the dry dock phase of the RCOH, USS John C. Stennis received significant upgrades and began an extensive overhaul process, both inside and outside the ship. In addition to defueling and refueling its power plant, NNS shipbuilders preserved tanks and replaced thousands of valves, pumps and piping components. On the outside, they performed major structural updates to the island, mast and antenna tower; upgraded all aircraft launch and recovery equipment; painted the ship’s hull, including sea chests and freeboard; restored the propeller shafts; and installed refurbished propellers and rudders.

During the next phase of RCOH, shipbuilders will complete the overhaul and installation of the ship’s major components and test its electronics, combat and propulsion systems. This period will also focus on improving the ship’s living areas, including crew living spaces, galleys and mess decks.

USS John C. Stennis is the seventh Nimitz-class aircraft to undergo its RCOH — the mid-life refueling overhaul and maintenance availability that produces a recapitalized carrier capable of supporting current and future Navy requirements. Once the RCOH is complete, USS John C. Stennis will be equipped to operate in the fleet for the second half of her 50-year expected service life.
