Sandia ensures US nuclear weapons deterrent can remain effective, credible

Sandia ensures US nuclear weapons deterrent can remain effective, credible

As part of its mission of ensuring the nation's stockpile is safe, secure and effective as a deterrent, Sandia National Laboratories must make sure crucial parts can function if they're hit by radiation, especially a type called fast neutrons. It created a science-based program called QASPR, which combines computer modeling and simulation, and experiments and technology development.

Wind tunnel tests support improved aerodynamic design of B61-12 bomb

Sandia National Laboratories has finished eight days of testing a full-scale mock unit representing the aerodynamic characteristics of the B61-12 gravity bomb in a wind tunnel. The tests on the mock-up were done to establish the configuration that will deliver the necessary spin motion of the bomb during freefall and are an important milestone in the Life Extension Program to deliver a new version of the aging system, the B61-12.
