The U.S. Navy signed a $3 billion aircraft carrier maintenance contract with Huntington Ingers Industries (HII) Newport News Shipbuilding, mainly for “Stannis”. “CVN-74, USS John C. Stennis performs loading nuclear fuel and refueling service (RCOH).
This refueling overhaul is expected to last for four years and be completed by August 2025.
According to the Defense World website on February 20, the U.S. Department of Defense said that the U.S. Navy Stanis has been in service until the middle of the year and needs to refuel, overhaul and modernize nuclear equipment to support the second half of its original 50-year service life.
Reloading and overhaul account for 35% of all maintenance and modernization required for the 50-year service life of nuclear-powered aircraft carriers.
The refueling overhaul of Stannis will include refueling two nuclear reactors of the aircraft carrier and modernizing more than 2,300 cabins and hundreds of subsystems.
In addition, the carrier-based combat system of the aircraft carrier will also be significantly upgraded, including the pilot system, aircraft catapults and electronic equipment upgrades on the island.
Stanis is the 7th ship of the Nimitz class aircraft carrier.
Construction began in 1991, was launched in 1993, and entered service at the end of 1995. It has been 25 years now.
At present, the three aircraft carriers belonging to the U.S. Navy, Stanis, Washington and Bush, are undergoing overhaul.
