Newport News Shipbuilding division recently placed a new upper-level structure on top of USS Abraham Lincoln's (CVN 72) island, which is similar to an airport control tower. The aircraft carrier is undergoing its refueling and complex overhaul (RCOH), during which the shipyard refuels the ship's reactors, paints the ship's hull, modernizes systems and performs a complete recapitalization of the entire ship.
The structure, which will contain the ship's primary flight control systems when outfitted and serves as the platform for many of its various radars and antenna systems, is one of the largest structure lifts that will be performed during the RCOH process. At 88 feet long and 32 feet wide, the structure weighs about 68 long tons, which is equal to the weight of nearly a dozen elephants. It was set into place using the 310-ton gantry crane that straddles dry docks 10 and 11.
USS Abraham Lincoln arrived at Newport News in March 2013 and is on track to redeliver in 2016.
