Refueling and Complex Overhaul (RCOH)

Optimizing Carrier Service and Performance

HII is only shipyard to execute the Refueling and Complex Overhaul (RCOH) of aircraft carriers halfway through a nuclear-powered aircraft carrier’s 50-year service. The mid-life RCOH includes refueling of nuclear reactors, overhauling most machinery, and modernizing warfare systems. RCOH ensures carriers incorporate improved capabilities needed for success in the remaining 25 years of service.
