Stockpile Stewardship Program

The Stockpile Stewardship Program is a U.S. government initiative aimed at maintaining and ensuring the safety, security, and effectiveness of the nation's nuclear arsenal without conducting nuclear tests. Established after the end of nuclear testing in 1992, the program employs advanced science, technology, and engineering to conduct experiments, simulations, and assessments. This helps scientists understand the aging of nuclear weapons and addresses any potential issues, ensuring that they remain reliable and effective as a deterrent while promoting non-proliferation and international safety.
