National Security, Weapons Science
National security depends on science and technology. The United States relies on Los Alamos National Laboratory for the best of both. No place on Earth pursues a broader array of world-class scientific endeavors.
National security and weapons science is at the core of ensuring the safety, security, and effectiveness of the U.S. nuclear deterrent and protecting against a radiological or nuclear attack on the United States. The research performed by laboratory scientists and engineers provides the base from which new, innovative solutions are developed for the nation’s nuclear security problems.
National security and weapons science at the laboratory spans essentially all the physical, life, and engineering sciences. Notable examples include:
- nuclear physics
- computer and information science
- earth and space sciences
- materials science
- energetic materials
- and many others
National security and weapons science supports a variety of deployed systems, both for the nuclear stockpile and for monitoring and understanding natural and man-made phenomena.
Los Alamos National Laboratory is the design agency for the W76/W88 Submarine Launched Ballistic Missile warheads, the W78 Intercontinental Ballistic Missile warhead, and the B61 gravity bomb. These four systems constitute 80 percent of the nation’s on-alert nuclear deterrent.
Examples of monitoring systems include ground- and space-based systems that the Lab produces for detecting violations of nuclear-test treaties.
