The ship is returning to the fleet after undergoing four days of sea trials to evaluate the crew and systems after more than four years of work, the service said.

The overhaul included refueling the large deck carrier’s two nuclear reactors, upgrading the ship’s infrastructure and modernizing combat systems and air wing capabilities, Naval Sea Systems Command said.

The work was done at contractor Huntington Ingalls Industries [HII] Newport News Shipbuilding yard in Newport News, Va.

Commissioned in 1986, the Roosevelt is expected to remain in service for another 23 years. The carrier, whose home port is Norfolk Naval Station, Va., will now begin local operations and flight deck certification.
