Serving the nation and our allies by providing a safe, secure, and effective stockpile

The Weapon Systems Engineering (W) Division provides system engineering and program management necessary to sustain the safety, reliability, and security of the Los Alamos National Laboratory-designed weapons in the active United States’ nuclear stockpile—the B61, W76, W78, and W88.

The Division generates key certification data for the Weapon Annual Assessment supporting the Laboratory Director's letter to the President on the health of these weapon systems. This role demands ongoing surveillance of the active stockpile and evaluation of the potential impact of any issues through design, engineering, fabrication, testing using state-of-the-art computational simulation tools and engineering test facilities.

The Division works closely with several of the production facilities across the nuclear security complex as well as with customers in the US Navy and US Air Force.

The Division continually strives to advance the capabilities underpinning its mission in engineering, explosives safety, and security.
