Bwx Technologies, Inc.
A maker of nuclear components and fuel, BWX Technologies builds reactors and parts for the U.S. Navy's submarines and aircraft carriers, manages high-consequence government sites, and supplies medical radioisotopes. It grew out of the Babcock & Wilcox boiler company founded in 1867, and spun off on its own in 2015. Its roots go back to the Manhattan Project, and it helped build the world's first nuclear-powered submarine, the USS Nautilus.
