Huntington Ingalls Industries will perform a four-year overhaul and upgrade of the nuclear reactor, flight deck, catapults, combat systems and island on the Nimitz-class carrier.

The Nimitz-class nuclear-powered aircraft carrier USS John C Stennis is to undergo a major Refuelling Complex Overhaul (RCOH) to ensure it remains in service for 25 more years, the DoD announced on 19 February.

The Newport News Shipbuilding division of Huntington Ingalls Industries (HII) will conduct the refuelling, overhaul and modernisation effort under a $2.99 billion contract from Naval Sea Systems Command, with work scheduled for completion in August 2025.

RCOH will involve the removal and replacement of expended nuclear fuel from the reactor aboard John C Stennis ‘to support the second half of its 50-year service life’, the DoD noted.

Other upgrade activities will focus on the propulsion plant, upgrades to the flight deck, catapults, combat systems and island.

Shephard Defence Insight notes that HII Newport News received a $290 million contract modification in August 2019 for continued planning of the RCOH for John C Stennis, which is the seventh Nimitz-class carrier to undergo a major life-cycle overhaul at the shipyard.
