Manufacturer catalog

Sandia National Laboratories

Sandia National Laboratories is a U.S. National Nuclear Security Administration laboratory responsible for nonnuclear components, systems engineering, quality assurance, testing, and stockpile support across U.S. nuclear weapon systems. Its manufacturer role in this catalog centers on Sandia's design-agency and systems-integrator work for B61-12 test and life-extension records.

2 weapons

Sandia is a government-owned, contractor-operated national laboratory with its largest site and headquarters in Albuquerque, New Mexico, and a second principal laboratory in Livermore, California. The laboratory is managed by National Technology and Engineering Solutions of Sandia, LLC, a Honeywell subsidiary, under an NNSA management-and-operating contract.

Within the nuclear security enterprise, Sandia develops and qualifies the nonnuclear parts, firing and control systems, test assets, and system integration work that allow U.S. nuclear weapons to meet military, safety, security, reliability, and surveillance requirements. Public NNSA and Sandia material describes that role across original design, stockpile assessment, life-extension programs, production support, and dismantlement.

For the connected catalog records, Sandia's public role is especially clear on the B61-12 program. Sandia describes itself as the design and engineering laboratory for the B61-12's nonnuclear components and as the systems integrator responsible for ensuring the B61-12 weapon system and subsystems work together; related Sandia and Air Force reporting also documents B61-12 Joint Test Assembly flight-test and surveillance work.
