The engineering issue

Welcome to the summer 2025 issue of National Security Science magazine. This issue features weapons engineering Los Alamos National Laboratory. A primary focus is the safety, security, performance, and reliability of the nation’s nuclear deterrent. Los Alamos engineers rigorously assess the aging stockpile, predict its long-term performance, and address emerging challenges to ensure its effectiveness. Simultaneously, Lab engineers look to the future—developing advanced weapon designs, improved components, and modernized delivery systems. ★
