Los Alamos National Security, LLC (LANS) comprises four top U.S. organizations that have extensive experience in nuclear defense programs—Bechtel National, University of California, BWX Technologies, and Washington Group International. Our combined record of accomplishments and awards is unmatched in both science and industry.

Los Alamos` core values combine security awareness, intellectual freedom, and scientific excellence with national service to generate scientific and engineering solutions for the nation`s most pressing problems. Maintaining the nation`s nuclear stockpile is Los Alamos` most important job; certifying that the nation`s nuclear weapons remain safe and reliable without underground testing remains the biggest technical challenge. The Laboratory is the second-largest manufacturing site in the nuclear weapons complex and one of only two national laboratories operating at this high level of mission importance and scientific excellence.
