Who manages and maintains America's nuclear weapons?

America's nuclear weapons are managed by the Department of Energy's National Nuclear Security Administration (NNSA). The work primarily takes place at the Pantex plant near Amarillo, Texas, where employees and contractors inspect, outfit, and maintain nuclear weapons with high explosives and radioactive cores of uranium and plutonium. The NNSA oversees the entire U.S. nuclear stockpile through a network of plants, labs, and bases nationwide. They also handle the transportation of nuclear materials on highways using specially trained armed personnel. This highly secretive and dangerous work is conducted by career professionals with specialized expertise, some with decades of experience.
