USS George H.W. Bush (CVN-77) is the tenth and final Nimitz-class supercarrier of the United States Navy. Northrop Grumman Newport News built the USS George HW Bush aircraft carrier. September 6, 2003, marked the laying of BUSH's keel - the bottom-most structure of the ship. Approximately 47,000 tons of structural steel and a million pounds of aluminum were used to construct the carrier according to a modular construction process. Try to imagine interlocking building blocks - each individual unit of the carrier was constructed and welded together to form a module weighing up to 900 tons.
