Huntington Ingalls Industries (HII) announced that the nuclear-powered aircraft carrier Gerald R. Ford (CVN 78) has put on significant weight in the dry dock at its Newport News Shipbuilding division with the installation of four 30-ton bronze propellers. At 21 feet in diameter, each propeller spins to push the aircraft carrier through the water. "Installation of the propellers culminates more than 10 months of focused work by numerous trades in support of installing the underwater shafting," said Rolf Bartschi, NNS' vice president, CVN 78 carrier construction.
