Huntington Ingalls Industries’ (HII) Newport News Shipbuilding division will carry out the mid-life refuelling overhaul and maintenance availability of the carrier.

The contract related to the vessel’s RCOH works was awarded to the company in February this year.

As part of the RCOH, Newport News shipyard workers will perform hull and freeboard blast and paint, as well as repair its propellers, sea chests, shafts, and rudders.

Workers will also defuel and refuel power plant.

According to HII, more than 4,000 Newport News employees will support the RCOH execution effort, which will run until 2025.

The RCOH programme will prepare the aircraft carrier to continue operating for another 25 years.

Newport News in-service aircraft carrier programmes vice-president Todd West said: “For the last three years, we have planned each step of the aircraft carrier USS John C Stennis’ (CVN 74) RCOH, including procuring long lead-time materials, conducting shipboard inspections, and readying our facilities for this extensive engineering and construction project.

“We look forward to continuing our work with the ship’s crew and our 579 vendors across 36 states that provide material and services which brings stability of this industrial base and is critical to our ability to continue to build and maintain the navy fleet our navy and nation needs.”

Christened in 1993 and delivered to US Navy in 1995, USS John C Stennis is the seventh Nimitz-class aircraft carrier to undergo an RCOH programme.
