NNSA delivers the U.S. nuclear stockpile, strengthens nonproliferation, powers a global naval fleet & advances transformative tech. Led by @NNSAWilliams.
NNSA teams train hard so they are ready when it matters most. NNSA recently hosted the 2026 Active Assailant Response Workshop bringing protective force officers, firefighters, and emergency responders together for realistic training that improves teamwork, communication, and lifesaving response.
