USS Theodore Roosevelt at Newport News Shipbuilding for refueling and complex overhaul (RCOH) in 2012.

Newport News Shipbuilding is the only shipyard to perform refueling and complex overhaul work on Nimitz-class aircraft carriers. This massive undertaking was described in a 2002 Rand Study as one of the most challenging engineering and industrial tasks undertaken anywhere by any organization.

The nearly four-year project is performed only once during a carrier’s 50-year life and includes refueling of the ship’s two nuclear reactors, as well as significant repair, upgrade and modernization work. We have completed the refueling and complex overhaul of the first five ships of the Nimitz-class, USS Nimitz (CVN 68), USS Dwight D. Eisenhower (CVN 69), USS Carl Vinson (CVN 70), USS Theodore Roosevelt (CVN 71) and USS Abraham Lincoln (CVN 72). Today, we are performing this work on the sixth ship in the class, USS George Washington (CVN 73).
