About NNSA

Established by Congress in 2000, NNSA is a semi-autonomous agency within the U.S. Department of Energy responsible for enhancing national security through the military application of nuclear science. NNSA maintains and enhances the safety, security, and effectiveness of the U.S. nuclear weapons stockpile; works to reduce the global danger from weapons of mass destruction; provides the U.S. Navy with safe and militarily effective nuclear propulsion; and responds to nuclear and radiological emergencies in the United States and abroad.

NNSA Mission: To deliver weapons that deter our adversaries and reassure our allies. To protect the homeland from nuclear and radiological threats. And to power the world's strongest navy – all in service of protecting America’s national security.

NNSA Vision: Deterrence | Urgency | Production
We will build weapons that deter our adversaries. We will move with the urgency demanded by today’s national security challenges. And we will return to our Manhattan Project roots as an organization focused on production.
