The mission of Los Alamos National Laboratory is national security.
Most Los Alamos employees are working to help ensure the safety and reliability of the nuclear weapons in our country's stockpile. Many others work to prevent the spread of weapons of mass destruction and to protect our homeland from terrorist attack. Much of their work relates to Laboratory's work on national security and must be kept secret. There is, however, a great deal about national security and the nuclear weapons work being done at Los Alamos that is unclassified.
