NEWPORT NEWS, Va. (NNS) -- USS Theodore Roosevelt (CVN 71) reached a major milestone Oct. 8 when the 0-10 level of the ship's island was installed during the ship's on-going refueling and complex overhaul (RCOH) at Northrop Grumman Newport News Shipbuilding.
The installation was accomplished using Northrop Grumman's massive 310-ton crane at drydock 11. The assembly of the ship's island represents a major construction milestone that paves the way for installing the ship's lower mast in December and completing all necessary top-side work before the ship undocks and moves to pier three early next year.
"The 0-10 level is the largest, heaviest structural unit moved by the shipyard for the ship," said Lt. Cmdr. Steven Hernandez, USS Theodore Roosevelt combat systems maintenance officer. "The 0-10 level is the foundation, the building block for the new and improved lower mast."
The 66-ton 0-10 level structure houses radar, communication and other electronic equipment. During the ship's RCOH, most of the original structure and components from the 0-4 level and above are completely removed, reconfigured or strengthened to accommodate the ship's new mast.
Capt. William J. Hart, USS Theodore Roosevelt commanding officer, said it is important for the Sailors to see the island take shape.
"The O-10 lift and placement represents a tangible inflection point; we are rebuilding this warship to take its place on the line," said Hart.
With the 0-10 level now in place, work can begin on running cables, installing ventilation, and laying foundations for the state-of the-art electrical equipment that TR Sailors will test and operate.
"When the island takes shape, you stop seeing the ship being taken apart, and you start to see the ship being rebuilt," said Hernandez.
RCOH is an extensive yard period all Nimitz-class aircraft carriers go through near the mid-point of their 50-year life cycle.
During RCOH Theodore Roosevelt's nuclear fuel will be replenished and the ship's services and infrastructure will be upgraded to make her the most state-of-the-art aircraft carrier in the fleet and prepared for another 25 years or more of service.
