The U.S. plans to conduct tests on its nuclear weapons systems.
The tests will not involve nuclear explosions but they will examine the system functionality, geometry, and delivery mechanisms.
The purpose is to evaluate the new systems and ensure replacement nuclear weapons perform effectively.
The U.S. previously conducted nuclear test explosions in the 1960s, 1970s, and 1980s, and now uses advanced simulations to predict detonation outcomes.
Officials cited monitoring global nuclear developments (Russia, China, North Korea) and maintaining strategic readiness as reasons for testing.
