Ensuring tomorrow’s U.S. nuclear deterrent through stockpile life extensions, while maintaining and advancing knowledge and capabilities

The Weapon Stockpile Modernization (Q) Division provides the system engineering, program management, component technology development, and system and sub-system testing necessary to field modernizations authorized to extend the life of Los Alamos National Laboratory-designed weapons in the active United States nuclear stockpile.

Currently, these modernizations are directed at the B61 and the W88 programs. This role demands expertise in design, engineering, fabrication and testing of multiple components 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 U.S. Navy and US Air Force.

The Division is also tasked with anticipating a broad range of possible future modernizations and with developing the various technology advances that might be required.
